Installation of EJB Adapter

I am trying to install EJB adapter but I am getting the following error
“Introspection failed (052) Could not introspect adapter class com.wm.adapter.ejb.EJBAdapter.
java.lang.ClassNotFoundException:com.wm.adapter.ejb.EJBAdapter”

I have checked the classpath…the following jar files also exist in the classpath.

CLASSPATH=lib/jars/jndi.jar;lib/jars/javax_ejb.zip;lib/jars/log4j-full.jar;lib/ejbAdapter42.jar;

Any suggestions

We see this error message come up if we install the adapter to a different directory that what the Enterprise Server is looking for.
