Thanks Karl, Here is quick summary on how I embedded Manifold in my
application.
- All the required manifold jar dependencies are in pom.
- The properties.xml is served through org.apache.manifoldcf.configfile
settings in catalina.properties
- There is an application ready Lister where I do following things.
IThreadContext tc = ThreadContextFactory.make();
ManifoldCF.initializeEnvironment(tc);
ManifoldCF.registerThisAgent(tc);
ManifoldCF.reregisterAllConnectors(tc);
AgentsDaemon.startAgents(threadContext)
One thing which I observed is that the "threadContext" which is using for
API *AgentsDaemon.startAgents( threadContext )* is different than the
other initialization APIs. Is this causing this issue?. But I can create
jobs and its running for while (may be weeks or months) until I am start
getting this exception. I mean I don't know the pattern which this is
happening. And I am still trying to understand that overlapping of thread
that you mentioned in previous mail.
