Error while CacheFactory.getCache

Question

Hello All,
I am trying a simple BPEL to call a Java Code which writes to coherence cache - I am getting the following error
Can someone please suggest what could be wrong.

Hi Avijeet,
It looks like that for whatever reason the context classloader is unable to see coherence.jar.
If you change com.oracle.coherence.handson.MyFirstSample to
            NamedCache  cache;
            Thread      thread     = Thread.currentThread();
            ClassLoader loaderPrev = thread.getContextClassLoader();
            try
                thread.setContextClassLoader(com.tangosol.net.NamedCache.class.getClassLoader());
                cache = CacheFactory.getCache(sName);
            finally
                Thread.currentThread().setContextClassLoader(loaderPrev);
                }this problem will go away.
Regards,
Dimitri
