Hi,


I recently updated one of our RHQ plugins to include an implementation of ws-management. I added the following jars to the lib/ folder within the plugin jar:


wiseman-core.jar

wiseman-client.jar


We have a ResourceComponent which uses an API, which in-turn uses ws-management to make configuration changes to one of our other servers. However, when we call this API in our ResourceComponent , and it tries to use ws-management, I'm getting the following error:


java.lang.reflect.UndeclaredThrowableException

I'm not sure why this is happening. The class: com.sun.ws.management.transfer.Transfer exists in wiseman-core.jar, which is included in the lib/ directory within the plug-in jar. I'm pretty sure this is the right location to put the jars, since I have other jars in this lib/ folder, and the plug-in seems to use them just fine (i.e. it seems to be able to use wiseman-client.jar) .


Does anyone know why this issue would be happening, and how I could resolve it? Appreciate the help


Thanks
