JNDI lookup

[swarna jaya]

Hi ,
When trying to access an EJB from a Java client, I get the exception
Cannot instantiate class: com.ibm.websphere.naming.WsnInitialContextFactory [Root exception is java.lang.ClassNotFoundException: com.ibm.websphere.naming.WsnInitialContextFactory].
What could be the problem? Could the problem be with the classpath settings or is some work required to be done in the Adminsitrative console. I am using Websphere Application Server 4.0
Please help
Thank you Swarna

Do u have all client jar files containing stubs on the classpath of your client program.
Do u using VAJ to develope then generate the client.jar file from VAJ and put the same in classpath of your client program.

Hi Mike,
Thanks for the help. But what are the client jar files required? I have the home interface,remote interface, bean class in a jar and I have made sure this is in the classpath. Apart from this what else is required?
Thank you Swarna jaya

I think ur missing the jndi.jar from ur classpath (which should contain that WsnInitialContextFactory class). However, I recommend u use launchClient to run ur client application. Look into Kyle's Workbook and it gives a very lucid explanation of the process.

Swarna,
Make sure your EJB is in the JNDI tree. With WebSphere running, run WebSphere/Appserver/dumpNameSpace.bat.
I second looking at Kyle's EJB workbook www.store.yahoo.com/titan-books/download.html
*** although note workbook Errata -> www.jmiddleware.com/workbooks/websphere_errata.html
I did have success once "Uninstalling" an EJB and "reinstalling" FWIW with AEs using the Admin Console.
Hope that helps.

Hi Mike,
DumpNameSpace.bat is to be run from this location
d:\websphere\appserver\
or from
d:\websphere\appserver\bin
this location.
thanks

R,
Yes, /WebSphere/Appserver/bin.
Sorry for the typo.
