IfsException (IFS-10811) starting the example LoggingAgent

Question

Hi,
I am trying to write my own Agent for iFS 9.0.1.
The compilation goes fine but when trying to launch it in standalone mode,
an exception occurs.
To be sure it is not an implementation problem, I tried to launch the
LoggingAgent provided in the "samplecode" folder. I get the same error:
10/10/02 4:22 PM LoggingAgent: Requested to start
10/10/02 4:22 PM LoggingAgent: Starting

The message complains about an "invalid class path specification". However,
I am sure the class "oracle.ifs.server.cache.BoundedLibraryObjectCache" is
present in the classpath (in the repos.jar library).
Is this problem related to cache size ? If so, how can I increase the cache ?
I know the Agent reads its configuration file (LoggingAgent.def) correctly and
uses the appropriate service name and schema password because the main method
succeeds to start the service and to initialize the LoggingAgent instance.
The failure happens when the connectSession() method is invoked in the
preRun() method.
Any help will be greatly appreciated,
Tristan

I hate to suggest this, but this impliens that the IFS repos did not install properly. Can you try re-running the ifsconfig process and either create a new repos, or re-initialize your existing repos (Be careful re-initializing an existing repos will cause all info in the repos in the lost).
