I think I have tried everything to fire up some browser applets in some web-pages that I am visting frequently. Everything was OK under FC 5 - Firefox -2, but now it just does not start. I expect a login screen as the first response to starting up, but it does never appear. - I have installed the libjavaplugin_oji.so softlink in /home/<my user>/.mozilla/plugins - I have tried both jre 6 and jre 5 (i have installed the .bin self extracting file according to some advide I found) - I have Gooogled extensively to get hints, some were fond, but they did not work. - I have checked /usr/java/jre1.5.0_16/bin/ControPanel, as well as the /usr/java/ jre1.6.0_07/-ditto- and I cannot find anything wrong. - Right now the ..-oji.so points to jre1.5....
- Perhaps Firefox-9 searces in some other location to find this link? I have found no hint about that. In FC 5 this works like a charm.
- One text I found hinted that this area is full of potential trouble, and one issue is which version of C has been used to compile both Java and Firefox.
Does anyone have some experience in this area?

See if you have the package below installed and if not, install it. Java works just fine once installed, and no symbolic links or anything needs to be created.

Hi again, this is really puzzling. This is what I have:
Java(TM) Plug-in 1.5.0_16-b02
File name: libjavaplugin_oji.so Java(TM) Plug-in 1.5.0_16
that is - the same as you. On my old computer i have JRE 1.6.0_05 and Firefox 2.0.0.16. Now the certificate of the applet in question has expired, so its name is diplayed and I am promted to confirm that I want to run it. So I know its name. When I accept it it takes opens a new window, running interactive Java application ps ax shows that java-vm is running. Perhaps this is part of the problem in the new environment. How do I check that -vm is ready to go to work? ( I have litte Java experience - which I obviously have to do something about - I work with C) Is there any other way to detect what Firefox 3 does with this applet when trying to start it? That might give a clue as to what's (not) going on.
NB! I have another URL which I access from time to time, this has a frame on top of the screen displaying a series of highlights pertaining to the page (a sort of "whats new" flash), and this applet works. But it is simple, and it is working wihin the web page, it does not launch an application in a new window. Maybe Java VM is the problem (?)

Well, my Intel Core 2 Duo came like yours, installed with 32-bit Linux, but it is certainly 64 bit capable. I'm running x86_64 on it now. From what I've read, here and elsewhere, if you run a 64-bit version of Linux on it, you should be able to use all 4GB of your RAM.

also, by any chance are you running 'noscript'? this is an extension that you have to install to get into firefox. if you did not install it, or do not know, then you probably do not have it.
to also see what you have install, in main menu bar, click 'tools > add-ons', then check 'extensions' and 'plugins' to see what extras you have. anything under 'extensions' will be 'noscript', if you have it. under 'plugins', you should see 'java' and what ever else you have added.
what do you have listed?
Is there any other way to detect what Firefox 3 does with this applet when trying to start it?
good question. there may be, but i can not answer. maybe mozilla-firefox faq will give answer or someone from list. or you could search from mozilla site for java.

Yes it is, though may have to search for it. It's an add-on that disables all scripts on pages you visit. You can then re-enable them selectively, either for the current session or permanently. Very useful and highly recommended.

I think what needs to be understood is that, at least for me, the Sun supplied java pieces work just fine with the URLs that you have listed.

As far as I can tell you have both the open-java as well as the Sun java environments installed. It isn't clear to me what environment is being picked up by your browser.

Ok, that may be it. I'd better clean the PC of everything Java runtime-related, and reinstall the programs from Sun. Fedora 9 had Java installed ($java did execute before I started downloading anything) I guess this is Java Development then - since JRE was missing. Am I then safe to assume that removal of everything under /usr/java/jre1.n... (I have both n=5 and n=6) will be enough? The libjavaplugin_oji.so is set to point to jre1.5... and I cannot remember where I got that from. So, my procedure would be: Delete everything below /usr/java - download jre.1.5-- from Sun and install it. (I did also use www.java.com before) I did not use .rpm downloads, some advice I picked up in some article I read. I have observed that the install procedure (starting the self extracting .bin file) is creating some libraries, do I have to remove these as well, or will they be overwritten? I cannot remember where they were located, perhaps yum can list then .. (that I cannot remember either, I am going to buy more memory! :-) ) BTW: In what environment exactly did you manage to bring up the login screen? You use jre1.5--- ?
The open-java stuff does not work.
As far as I can tell you have both the open-java as well as the Sun java environments installed. It isn't clear to me what environment is being picked up by your browser.
Honestly, it is not clear to me either right now. I was not aware that this was an issue, so I did not think about it at all.
But I hope the strategy designed above will get this straight.

- I have installed the libjavaplugin_oji.so softlink in /home/<my
user>/.mozilla/plugins
- I have tried both jre 6 and jre 5 (i have installed the .bin self
extracting file according to some advide I found)
- I have Gooogled extensively to get hints, some were fond, but they
did not work.
- I have checked /usr/java/jre1.5.0_16/bin/ControPanel, as well as the
/usr/java/ jre1.6.0_07/-ditto- and I cannot find anything wrong.
Right now the ..-oji.so points to jre1.5....
Perhaps Firefox-9 searces in some other location to find this link?
I have found no hint about that. In FC 5 this works like a charm.
- One text I found hinted that this area is full of potential trouble,
and one issue is which version of C has been used to compile both Java and Firefox.
Does anyone have some experience in this area?
Different versions of java, and other version specific tools and applications, can happily co-exist on Fedora. This is what the alternatives tools are for.
You can, with impunity, install the latest java rpms from SUN and test them. You can switch back, or forth, to any version, at any time. The Fedora java (iced tea) is the SUN java, just missing some libraries that are not licensed as OSS, yet.
It is also worth mentioning, that java.sun.com will allow you to download any previous version.
I DO recommend the rpms for simplicity.
alternatives takes about 10 minutes to figure out, and then you keep a couple scripts handy for future reference.
Like all super flexible applications, there is an easy way, and very complex methods for using alternatives. I will happily share the 'easiest' way to make it happen.
# fix alternatives rm /var/lib/alternatives/java /usr/sbin/alternatives --install /usr/bin/java java /usr/lib/jvm/jre-1.4.2-gcj/bin/java 1 /usr/sbin/alternatives --install /usr/bin/java java /usr/java/jdk1.6.0_04/bin/java 2 /usr/sbin/alternatives --install /usr/bin/javac javac /usr/lib/jvm/jre-1.4.2-gcj/bin/javac 1 /usr/sbin/alternatives --install /usr/bin/javac javac /usr/java/jdk1.6.0_04/bin/javac 2
Simply change the names as desired, and fire away! No need to remove anything.
The result of these commands are:
/usr/bin/java, /usr/bin/javac will point to the versions in /usr/java/jdk1.6.0_04/bin
easy!
You already know how to make the link for mozilla/firefox, but alternatives could do that, too.
Enjoy!

It is a flash application.
Start with www.cbfx.com Click Live Account Login - choose ICTS institutional login Then "Platform Login (java version)" Then this URL is launched: http://live.cbfx.sysfx.com:8100/trade/trade.jsp?entry=deal.77&lang=en_US and (when it works) after some processing the login screen appears. At the top of this screen (with red capital letters (CLOSE THIS PAGE ONLY...) there is a marked triangle in grayish color which used to display the Java symbol as the applet was firing up. Now nothing happens and the message line at the botton says "Done".
OK....
This works fine in one of my environments. I get the login applet.
Fine!!
Both these are made for JRE 1.4... are there major revisions in 1.5 that might cause problems?
This works fine on FF 3.0.1 and Java(TM) Plug-in 1.6.0_07-b06 on RHELv5. It does not work on FF 3.0.1 with:
GCJ Web Browser Plugin (using IcedTea) 1.2

gcjwebplugin.so does not work as hoped. This is the open source environment.
Is there something else besides gcjwebplugin.so that might help execute java applets?
I think what needs to be understood is that, at least for me, the Sun supplied java pieces work just fine with the URLs that you have listed.
Ok, that may be it. I'd better clean the PC of everything Java runtime-related, and reinstall the programs from Sun.
That should not be necessary. Multiple versions of multiple VM's can co-exist peacefully. I have had machines with different versions of 4 jvms (IBM/BEA/Sun/IcedTea) and they have been fine. It appears there is some issue with setup on your end.
Fedora 9 had Java installed ($java did execute before I started downloading anything) I guess this is Java Development then - since JRE was missing.
Right, once you have java-1.6.0-openjdk installed, "java" should work.
Am I then safe to assume that removal of everything under /usr/java/jre1.n... (I have both n=5 and n=6) will be enough?
Only Sun rpms install in /usr/java AFAIK. Removing those rpms should clean up that directory. Alternatively, those dirs may have come from manually extracting the Sun binary distribution, in which case you can just rm -rf them to clean up.
The libjavaplugin_oji.so is set to point to jre1.5... and I cannot remember where I got that from. So, my procedure would be: Delete everything below /usr/java - download jre.1.5-- from Sun and install it. (I did also use www.java.com before) I did not use .rpm downloads, some advice I picked up in some article I read. I have observed that the install procedure (starting the self extracting .bin file) is creating some libraries, do I have to remove these as well, or will they be overwritten?
Everything extracted by the Sun .bin is in a single dir, so removing that should be enough.
I cannot remember where they were located, perhaps yum can list then .. (that I cannot remember either, I am going to buy more memory! :-) ) BTW: In what environment exactly did you manage to bring up the login screen? You use jre1.5--- ?
The open-java stuff does not work.
openjdk in Fedora 9 currently uses the GCJ web plugin, which lacks LiveConnect support. So sites that make use of that will not work. We are working on that support, and you can always check out iced tea and try out the new experimental plugin if you like to live on the edge :)
As far as I can tell you have both the open-java as well as the Sun java environments installed. It isn't clear to me what environment is being picked up by your browser.
Honestly, it is not clear to me either right now. I was not aware that this was an issue, so I did not think about it at all.
The environment picked up by the browser plugin is dependent on where the linked .so points to. If you want to use the Sun plugin for example, make sure that the .so in the plugins dir (~/.mozilla/plugins/ or /usr/lib/mozilla/plugins) is a _symlink_ to the .so in the java dir. Copying the file will probably not work..
For example, if you want to use the vm in /usr/java/jdk1.5.0_10/ , make sure you have a link:
libjavaplugin_oji.so -> /usr/java/jdk1.5.0_10/jre/plugin/i386/ns7/libjavaplugin_oji.so
In one of those plugins dir. If you have that, that is the jvm that will be used.
Cheers, Deepak
But I hope the strategy designed above will get this straight.

I'm not sure, but perhaps as you have 2 java plugins showing in about:plugins, maybe Firefox is defaulting to using the iced tea one, which I've found has had problems with some sites.
if you type about:config, then scroll down to "plugin.expose_full_path", then double click on this line, you should now in about:plugins, see where the iced tea one is. Perhaps re-name it, then try the site again, which should now be using the one from Sun.
All the best.

expose_full_path gives:
the GCJ Web *Browser Plugin (using IcedTea) 1.2 is found in: /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0/jre/lib/i386/gcjwebplugin.so

Yes, I think you have started to confuse yourself...and potentially others. :-)
First, the Sun Java plugin is supposed to be in the location you indicate above.
Second, I *think* you have placed a symbolic link in your ~/.mozilla/plugins directory pointing to it since I *think* have have indicated that typing "about:plugins" in FF shows the existence of both gcjwebplugin.so and libjavaplugin_oji.so.
As I've already mentioned, I've not tried working on a system with both Sun's Java stuff and open Java stuff installed on the same system.
So, why don't you simply uninstall the open-java stuff and try using *only* Sun's Java? I have mentioned that it *does* work here on both of the sites you indicated.

I have observed that the install procedure (starting the self extracting .bin file) is creating some libraries, do I have to remove these as well, or will they be overwritten? I cannot remember where they were located, perhaps yum can list then .. (that I cannot remember either, I am going to buy more memory! :-) )
I would surely buy more memory. :-)
I would also recommend using the rpms in the future. Makes installing/uninstalling/updating much easier.
FWIW, you can also confirm what lib FF is referencing by doing an:
lsof -p XXXX where XXXX is the PID of FF and then grepping the output for "plugin".
BTW: In what environment exactly did you manage to bring up the login screen?
My environment is Red Hat Enterprise Linux V 4.7 with FF 3.0.1 and Sun's latest java and java plugin.
You use jre1.5--- ?
No, I've installed Sun's jdk-1.6.0_07-fcs.
I downloaded
JDK 6 Update 7
/The Java SE Development Kit (JDK) includes the Java Runtime Environment (JRE) and command-line development tools that are useful for developing applets and applications.
/from the SUN site.
I went through the motions, executing the ....*.rpm.bin inder /usr/java, created symlinks (libjavaplugin_oji.so) both in ---/.mozilla/plugins and (to be sure) /usr/lib/mozilla/plugins.
Still no effect. And the funny thing is: about:plugins now report this:
Java(TM) Plug-in 1.6.0_06-b02
File name: libjavaplugin_oji.so Java(TM) Plug-in 1.6.0_06
I was expecting _07, not _07 if the last 2 digits identify the update number.
I also have:
GCJ Web Browser Plugin (using IcedTea) 1.2
File name: gcjwebplugin.so The GCJ Web Browser Plugin (using IcedTea) executes Java applets.
I can't think of a reason to have both of these.
I now have only Sun's Java installed on FF 9. I "rpm -e" the open-java stuff. And both of your sites run just fine. -- snip --
Then there should be hope for me as well. But I must admit that I have not dived into this java plugin stuff so much before, (under Fedora Core 5 it was just to enter the softlink .._oji.so in /home/.../.mozilla/plugins and then everyting played nicely. So there is a lot of new stuff now that I try to bring under control. Therefore I am compelled to ask more uninformed questions: rpm -e ? I.e: What should I enter after the erase clause to make sure that I get it all erased?
rpm -e java-1.6.0-openjdk java-1.6.0-openjdk-plugin
is all you need do.
java-1.6.0-openjdk ,jre-1.6.0-openjdk etc appears in several directories (Dolphin Find File search) /usr/lib/jvm /usr/lib/jvm-exports /usr/share I want to make sure that I know what I am doing now, which I am not sure that I do, because there is quite a flow of details to manage.

This is where I found it after installing the Sun Java, so it seems to fit. I moved the *.rpm.bin to /usr/java and executed the .bin there.
Could I have crossed my eyes and downloaded the wrong Java from the Sun site? Now there are so many details on the table that I am struggling against my own confusion. :-)
Yes, I think you have started to confuse yourself...and potentially others. :-)
I am very sorry if I have not managed to ask precise question, and give all important details.
First, the Sun Java plugin is supposed to be in the location you indicate above.
Then there is one item that is correct.
Second, I *think* you have placed a symbolic link in your ~/.mozilla/plugins directory pointing to it since I *think* have have indicated that typing "about:plugins" in FF shows the existence of both gcjwebplugin.so and libjavaplugin_oji.so.
the symbolic link IS placed in ~/.mozilla/plugins, that is correct. gcjwebplugin also exists, that is correct.
As I've already mentioned, I've not tried working on a system with both Sun's Java stuff and open Java stuff installed on the same system.
I have a t'strong feeling that this must be the problem!
So, why don't you simply uninstall the open-java stuff and try using *only* Sun's Java? I have mentioned that it *does* work here on both of the sites you indicated.
Yes, I will do that, ref. my last mail where I want to make damn sure that I know what I am doing, i.e. doing it correctly. Or is it as simple as rpm -e openjdk?
How about using yum remove? I was checking earlier whether the open stuff was installed. I got that advice, saying that no symlinks should be necessary if this is properly installed. It was properly installed, but noting worked.
I ask all such silly questions to be sure that I make no mistakes due to many detalils and my own confusion about things. My speciality is not programming or maintenance in the system environment, I do applications (in finance for trading purposes - you might have guessed that), and I simply do not have the time to learn everything there is to know about whats going on behind the curtain. That makes me feel stupid, yes, but there are only 24 hours a day available.

Ok, that may be it. I'd better clean the PC of everything Java runtime-related, and reinstall the programs from Sun. Fedora 9 had Java installed ($java did execute before I started downloading anything) I guess this is Java Development then - since JRE was missing. Am I then safe to assume that removal of everything under /usr/java/jre1.n... (I have both n=5 and n=6) will be enough? The libjavaplugin_oji.so is set to point to jre1.5... and I cannot remember where I got that from. So, my procedure would be: Delete everything below /usr/java - download jre.1.5-- from Sun and install it.

rpm -e gave error messages, but yum remove did the trick. And THEN: The login screen popped up, and everything worked as it used to work after logging in.
I am very grateful for all good help, I have learned a lot from this, I have some more understanding of how Java plugins work, but also how Firefox deals with plugins. I will study Java more and use it for some purposes, then I don't have to ask so many uninformed questions - hopefully.

Hi: I also experienced the same problem, so I switched over to SUN Java. I did this as per instructions given at http://www.mjmwired.net/resources/mjm-fedora-f9.html#java. You may test the status of your browser with http://webapps.ou.edu/it/browser. Sivaraman.

Also in reply to Ed: There are two web-pages (both for interactive currency trading):
Do you mean the login at https://live.webtradingonline.com/web/webtrading.aspx ?
It is a flash application.
Start with www.cbfx.com Click Live Account Login - choose ICTS institutional login Then "Platform Login (java version)" Then this URL is launched: http://live.cbfx.sysfx.com:8100/trade/trade.jsp?entry=deal.77&lang=en_US and (when it works) after some processing the login screen appears. At the top of this screen (with red capital letters (CLOSE THIS PAGE ONLY...) there is a marked triangle in grayish color which used to display the Java symbol as the applet was firing up. Now nothing happens and the message line at the botton says "Done".
OK....
This works fine in one of my environments. I get the login applet.
Both these are made for JRE 1.4... are there major revisions in 1.5 that might cause problems?
This works fine on FF 3.0.1 and Java(TM) Plug-in 1.6.0_07-b06 on RHELv5. It does not work on FF 3.0.1 with:
GCJ Web Browser Plugin (using IcedTea) 1.2
File name: gcjwebplugin.so The GCJ Web Browser Plugin (using IcedTea) executes Java applets.
This is installed -- but it does not work in your environment? Maybe that is the problem then,... and RHEL - Red Hat Enterprise?? What plugin does it use to execute applets?
gcjwebplugin.so does not work as hoped. This is the open source environment.
Is there something else besides gcjwebplugin.so that might help execute
java applets?
I think what needs to be understood is that, at least for me, the Sun supplied java pieces work just fine with the URLs that you have listed.
The open-java stuff does not work.
As far as I can tell you have both the open-java as well as the Sun java environments installed. It isn't clear to me what environment is being picked up by your browser.

My PC is only 2-3 weeks old in my possesion and this is my first encounter with Fedora 9. (Earlier I was running Fedora Core 5) The only screen resolution option I have now is 640x488, and I would like to change that. So I took a look at the ../resources/.. site, where I found instructions for downloading Nvidia-driver:
$yum install kmod-nvidia , nvidia installation through Livna.
Installation went OK , and I did reboot the PC as recommended, but no change, and the PC does not identify the LCD. It is "unknown" to it. It is configured as Vesa, which I guess is the best option when nothing else is known. But I saw a message flashing over the screen on bootup stating something about the Nvidia driver - it would not take effect until.... something I did not manage to read before it vanished. Does anyone know what I should be looking for? (I did demsg, but no trace of the message there)

Since this new question has nothing to do with Java applets you need to start a new thread.
