Java EE (Java Enterprise Edition) General Discussion

Hi All,

I have already tried some sample examples using WSAD 5.1 , successfully deployed and run many types of beans. Now just today i tried running one of the sample bean which displays "HelloWorld" message, I started getting all these errors.


When starting the websphere server I get the below error :

[8/11/04 15:05:37:656 EDT] 4f4e4f4e ConcreteBeanC E PMGR1000E: Exception occurred :com.ibm.websphere.naming.CannotInstantiateObjectException: Exception occurred while the JNDI NamingManager was processing a javax.naming.Reference object.

And when i try running the sample "HelloWorld" session bean it gives error :


javax.naming.NameNotFoundException: Context: localhost/nodes/localhost/servers/server1, name: ejb/my/examples/Hello: First component in name Hello not found. Root exception is HelloClient Runtime error Context: localhost/nodes/localhost/servers/server1, name: ejb/my/examples/Hello: First component in name Hello not found.

I remember getting this NameNotFoundException errors before but i don't remember what setting is required to be made. Can anyone help me out with it?

Thanks in advance .
