How to debugging tomcat5 mailer problems
by Peter Carroll 30 Aug '06

30 Aug '06

I am completely lost on this one. I have a tomcat5 web application running on Fedora Core 4. It ran perfectly until a few months ago when suddenly it stopped sending email. I was using the Jakarta mail-1.1 taglib and it looked like it worked but nothing went out. I started using the mailer2 taglib and that finally gave me some errors (below). Even the examples don't work. Initially I had this on both my development and production servers. I hacked away at the dev server replacing jar files and restarting and eventually it all went away. I then reconciled that with my production server and nothing works. I am sure it is some kind of version conflict as it showed up as quickly as it went away. I've been beating my head on this for a couple of months now with no progress at all. Can someone please suggest an approach to debug this? I'm at a total loss. Thanks Peter The code as follows: <%@ page contentType="text/html" %> <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> <%@ taglib prefix="mt" uri="http://jakarta.apache.org/taglibs/mailer2" %> <mt:mail from="peter.carroll(a)xxxxxxx.org" to="peter.carroll(a)xxxxxxx.org" subject="simple mail example using mt:send" background="false" > Hello,

interpreter mystery
by Anthony Green 30 Aug '06

30 Aug '06

gdb tells me that the azureus in x86 rawhide doesn't appear to be running any of the Azureus or SWT .jar.so code. It's all being interpreted. However, lsof tells me that both the Azureus and SWT .jar.so files are being held open by the gij process. This doesn't appear to be a system-wide issue, since I can see that tomcat5 is not being interpreted (again, via gdb). But looking at rssowl, I see the rssowl .jar.so _is_ being used, but swt's .jar.so isn't (despite being held open by the process). Any ideas or suggestions? AG

gcj trunk -> redhat/gcc-4_1-branch merge complete
by Thomas Fitzsimmons 24 Aug '06

24 Aug '06

Hi, gcc.gnu.org/svn/gcc/branches/redhat/gcc-4_1-branch-java-merge-20060823 now contains the trunk -> redhat/gcc-4_1-branch Java merge that I'd like to see go into FC6test3. libjava's "make check" passes except for the -O3 StackTrace2 tests: FAIL: StackTrace2 -O3 execution - source compiled test FAIL: StackTrace2 -O3 execution - bytecode->native test but these tests also failed on redhat/gcc-4_1-branch before my 2006-08-23 merge. Andrew, can you take a look at what's causing these failures? The merge includes the fix for PR13212, which fixes 33 tests that failed on redhat/gcc-4_1-branch before my 2006-08-23 merge, and will allow you to remove gcc41-java-pr13212.patch from the SRPM. I tested the following on i386 Rawhide: Eclipse - extssh mode works well, better than pre-merge when performance was unacceptably slow gcjwebplugin - works Azureus - works AWT/Swing - work much better than pre-merge, more responsive, no crashes Java2D - works much better than pre-merge, faster, no crashes Can we include this merge in the next Rawhide gcc release?

gcj trunk -> redhat/gcc-4_1-branch merge status
by Thomas Fitzsimmons 24 Aug '06

24 Aug '06

Hi, I tagged revision 116352 as redhat/4_1-branch-java-merge-20060823, and I committed the preliminary merge to the redhat/gcc-4_1-branch-java-merge-20060823 branch. The branch builds but there are still some test suite failures to work through. Once the test suite runs I'll move on to testing bigger applications. Tom

gcj trunk -> redhat/gcc-4_1-branch merge
by Thomas Fitzsimmons 23 Aug '06

23 Aug '06

Hi, I'm going to do the trunk to redhat/gcc-4_1-branch backport now. I'm planning to tag revision 116352 as "redhat-java-merge-20060823". If you have an outstanding patch that you want included in this merge, let me know today and I'll hold off tagging until you've committed it. Tom

aot-compile-rpm problem
by Anthony Green 23 Aug '06

23 Aug '06

Hi, On rawhide, when I do a "yum install java-1.4.2-gcj-compat-devel" on my x86-64 system I get both the x86-64 and x86 packages. I suppose the x86 version is written last, because aot-compile-rpm's LIBDIR is set to /usr/lib/gcj instead of /usr/lib64/gcj. This pretty much breaks rpm building. The fix is to make sure I just "yum install java-1.4.2-gcj-compat-devel.x86_64". Is this expected behaviour? I don't remember this being a problem for my in the past. Thanks, AG

GNU Classpath 0.92 release schedule and FC6test3 backport
by Thomas Fitzsimmons 14 Aug '06

14 Aug '06

Hi, I'm wondering when GNU Classpath 0.92 is scheduled to be released. I'm trying to plan for another backport before FC6test3. My main interest in a backport is pulling all the GUI improvements from GNU Classpath 0.92 to FC6test3, since there are some major ones including fixes for crashers. But I know that you're more interested in a complete backport, because it makes subsequent merges easier. I'm going on vacation next week, so if possible, I'd like for us to make a decision on our plan by tomorrow, so that I can start merging/testing immediately when I get back. Tom

Enviroment Variables
by Ryan Ollerenshaw 06 Aug '06

06 Aug '06

I can write a shell script that will set an enviroment variable using the export command, but then when i try and print the variable after the shell scrit has been run the variable is no longer set. Why is this? my problem is that i need to set some enviroment variables in a shell script that is run when my tomcat server is started, but after the startup script runs the variables are no longer set. Here is what i am using in my scripts: export CLASSPATH=/usr/root/ echo $CLASSPATH but then when i do a echo $CLASSPATH from the command line the original value is printed and not the one set in the shell script. any help would be great.

Tomcat Help
by Ryan Ollerenshaw 04 Aug '06

04 Aug '06

I am trying to set up Tomcat 5 on Fedora Core 5 and everything iw working find but i do not know how to set my classpath when using tomcat below is a few things that i have tried. I have found i can use the following code to print out the classpath that my program is actaully using, the code is: Get the System Classloader ClassLoader sysClassLoader = ClassLoader.getSystemClassLoader(); //Get the URLs URL[] urls = ((URLClassLoader)sysClassLoader).getURLs(); for(int i=0; i< urls.length; i++) { out.println(urls[i].getFile()); out.println("<br>"); } and the classpath that is printed is: /usr/java/j2sdk1.4.2_12/lib/tools.jar /etc/tomcat5/bin/dist/commons-daemon.jar /etc/tomcat5/bin/bootstrap.jar But i am not sure where this is getting set, i do have the following in my /tomcat5/bin/startup.sh export CLASSPATH=./mapscript.jar:.:/etc/tomcat5/webapps/my_test/WEB-INF/classes so why is this not my classpath at run time??

This should probably go in the java-1.4.2-gcj-compat package (our JDK compatibility layer on top of gcj).

gcjwebplugin has landed in Rawhide
by Thomas Fitzsimmons 03 Aug '06

03 Aug '06

Hi, gcc-4.1.1-12, which contains libgcjwebplugin.so, went into Rawhide last night along with java-1.4.2-gcj-compat-plugin which installs an alternatives-managed "libjavaplugin.so" symlink in /usr/lib/mozilla/plugins. I closed the long-standing "Inclusion of gcjwebplugin" bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=127537 and updated the release notes with a "Handling Java Applets" section: http://fedoraproject.org/wiki/Docs/Beats/Java Rawhide users can install gcjwebplugin with "yum install java-1.4.2-gcj-compat-plugin". Please try this out, file bugs and comment on the release note additions. The GNU Classpath AWT and Swing code was in a state of flux when the backport that included gcjwebplugin was done (because of a large Java2D rewrite to make the Cairo backend the default), so there are some regressions in AWT and Swing applications for FC6test2. My post-test2 plan for gcjwebplugin is to gage the reaction of Rawhide users, and also to do another GUI backport from GNU Classpath HEAD to Fedora's libgcj, to fix the AWT and Swing regressions. If the reaction turns out to be overly negative, even after the new AWT and Swing backport, we can always make gcjwebplugin not installed by default, for FC6test3. For FC6test2 though, it is installed by default if the Internet group is selected. Tom

fc6 extras java status
by Anthony Green 01 Aug '06

01 Aug '06

Things are a little ugly in fc6 extras java land... * Azureus makes my computer practically unusable because of libgcj's new SecureRandom implementation. I've filed a bug for a work around here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200653 Mark tells me this is the root cause of some crypto test timeout problems on the autobuilder as well. Casey says that this same code doesn't seem to have a problem on jamvm. * RSSOwl no longer fails to start because of the zip problem (thanks tromey!), but now crashes in _Jv_ClassReader::checkExtends (super = 0x3). I'm rebuilding libgcj with -O0 -g3 to debug. * I've updated jogl to jsr231 1.0 beta 5. The good news is that it builds sans patching! The bad news is that demos crash the X server (like, try resizing the gears demo). I think this is an X problem, so I'm going to push this out anyways because the latest WW2D (and "WW2D plus one", which looks awesome -- http://www.alpix.com/3d/worldwin/WW2d_Java.html) use this version of the jogl API. * kawa is fine.
