Sarang Anajwala [https://community.jboss.org/people/saranganajwala] created the discussion "javax.naming.NamingException: Could not dereference object [Root exception is java.lang.reflect.org.jboss.remoting.InvocationFailureException: Unable to perform invocation; nested exception is: java.io.EOFException: end of file]" To view the discussion, visit: https://community.jboss.org/message/720081#720081 -------------------------------------------------------------- Getting following exception while trying to connect to remote EJB. I tried to send 500 requests (through a for-loop in java client program) to the EJB.... about 400 went throgh and then I started getting this error, so certainly this is not a classpath issue or code issue. Anything related to configuration?
