| We have an application that communicates with WSRR using CORBA. Our application was working at one point and things seem to have broke recently. I can't track it down to any configuration made on the servers, so I don't really know where to start, excep
t it seems classloading related. The error is:<br />
<br />
org.omg.CORBA.MARSHAL: Unable to read value from underlying bridge : Class 'WSRR' not found. (file:///opt/WebSphere/AppServer/all.datagraph, 6, 15)<br />
vmcid: IBM minor code: 89A completed: No<br />
at com.ibm.rmi.iiop.CDRInputStream.read_value(CDRInputStream.java:1855)<br />

at com.company.wsrr.WSRREJBClient.retrieve(WSRREJBClient.java:101)<br />
...company specific classes...<br />
at java.lang.Thread.run(Thread.java:567)<br />
<p />
It's strange that that the "WSRR" class isn't qualified by a package name. Is there potentially some configuration or something else messed up here?<br />
<br />
I've enabled both ORB tracing and classloading via:<br />
ORBRas=all=enabled:com.ibm.ejs.containter.*=all=enabled:com.ibm.ws.webcontainer.*=all=enabled:WebSphere ClassLoader=all=enabled<br />
<br />
The native_stderr.log does have some error messages in it, but I can't tell if these are just informational or part of the root cause:<br />
<br />

Neither classloading or orb tracing displays any information about trying to load the "WSRR" class.
