Error on writing a connector using WSIF to provision users.

Question

Hello All,
I am writing a connector to provision users using WSIF. Everything works great through my IDE (eclipse on Windows XP), but when I drop the jar, map the adapter (using OIM 9.0.3, RH4, and weblogic 8.1 SP6) and invoke a process task I get the following error:
The WSIFDefaultMapper class exists in the wsif.jar file and as far as I can tell, only one instance of that class file exists (did a grep on all jar files).
Any pointers will be appreciated.

Answer 1

I have narrowed this down to the following (some of this is a repetition, I am copying and pasting my post from a WSIF forum):
I am using wsif wsif-2.0.1_IB3 to connect to a webservice to create user accounts. Everything works great in Eclipse.
When I deployed my jars (application jars, wsif and dependencies) to weblogic 8.1 sp6 and generate a task through OIM that calls this adapter, I run into the following error:
org.apache.wsif.WSIFException: Unable to create new mapper; nested exception is:
java.lang.ClassNotFoundException: org.apache.wsif.mapping.WSIFDefaultMapper

at org.apache.wsif.mapping.WSIFMapperFactory.newMapper(WSIFMapperFactory.java:100)
The WSIFMapperFactory.class exists in wsif.jar file and makes a call to newMapper but is unable to load org.apache.wsif.mapping.WSIFDefaultMapper that is in the same wsif.jar file.
public static WSIFMapper newMapper() throws WSIFException {
return newMapper(false);
The line that it fails on is Class c = Class.forName(mapperClassNameBuffer.toString(), true, Thread.currentThread().getContextClassLoader());
from the following code snippet in WSIFMapperFactory.class file
try {
Class c =
Class.forName(
mapperClassNameBuffer.toString(),
true,
Thread.currentThread().getContextClassLoader());
return (WSIFMapper) c.newInstance();
} catch (ClassNotFoundException cnf) {
throw new WSIFException("Unable to create new mapper", cnf);
} catch (Exception e) {
throw new WSIFException("Unable to create new mapper", e);
Any ideas on how to fix this?
I modified some of the WSIF code to try using the following:
Class c = Thread.currentThread().getContextClassLoader().loadClass(mapperClassNameBuffer.toString()); but it had the same effect.
Again, the same code path works great standalone in Eclipse.
Any help/pointers would be appreciated.
