In continuation of my previous post on working with SOAP nodes, I switched the compute node to start using a javaCompute node. But I have been running into numerous issues after I made this change.
We have the apache commons logging library in the shared-classes folder. It's more or less a given that there is no way we can remove that file from there since multiple projects at our work place are dependent on it. After I modified the flow by replacing ESQL code with java code, I deployed to the same execution group I was using before. Deployment goes through fine. Time to test I thought and proceeded to execute the same test case that I was previously running when I had the ESQL code. I do not have any logging statements in my java code nor were there any changes to our broker environment from the time I last tested. Here is what gets thrown into the stdout:

| What gets thrown to the flow? What gets logged in the system log? |

Service Log also has the same content that I have provided in the previous post above. User trace shows this:

Seems like a class-loading issue. The presence of the commons logging jar in the shared-classes makes the logger etc classes loaded by the Shared Classloader while the Axis2 library is in the webservices folder, contents of which are loaded either by the Common Classloader or Broker Classloader(mebbe even the JVM Classloaders). I strongly believe that's where the issue lies but do not know how to get around it....yet!

Have you looked at the configurable services for your classloaders?

configurable service for classLoading? How do I do that? I went through the infocenter and found no references to it.

Look at the community pages ... there was a webinar on stuff like that about a month ago... However it might be V7 only...

Yes you are right. I found that info in V7 infocenter.
I'm out of luck with this in V6.1 then!!!?

No JavaClassLoader configurable service in v6.1.
The classloader structure is different too.
Putting log4j into shared-classes however should not be interfering with MbService.log() though, afaik.
Make sure you're at 6.1.0.8, though. |

Can you try a newer 6.1 fixpac? I know there have been some classloading fixes in one of the 6.1.x releases, but I forget which...
