JMX Connections within Eclipse?

[scotta irwin]

Outside of Eclipse my code works fine. I'm getting a JMX Connector to a local agent using the following URL format.

service:jmx:rmi:///jndi/rmi://localhost ort/jmxrmi

Get the connector, get the MBean server and I'll all set.....

Within Eclipse I can't ge the connector due to the the following error. I have no clue why - same JDK specified. Eclipse must be sending the factory method down a different path and its looking for a class I don't have.

thanks in advance,

Scott

We've got a forum for IDE-specific questions here. I'll move this thread there for you.

I'm guessing that you mean you get this error when you attempt to run your app in an Eclipse debugging environment. If Eclipse just spontaneously spits out a stack trace when you copy code into a project - or whatever - I think I'd like to know before it happens to me!

Assuming that the above is true, there are 3 likely reasons for it.

1. You're using a different JRE when you run inside Eclipse. This is settable via the Run/Debug dialog.

2. Your runtime environment is pulling a different set of settings. This is also settable via the Run/Debug dialog. You can also dump the (java.lang.)System properties to check.

3. You are somehow pulling in different runtime libraries (classpath). The classpath is one of the System properties you can dump, BTW. If this is the problem, you have to add the appropriate classpath items - (e.g. jars) on the Run/Debug dialog.

Eclipse maintains its own environment for its internal use, but you have pretty much total control over the runtime and debug environments, so the first step is to try and find out where the differences are, then address them. Hopefully the above info will help.
