Hi,

I am trying to run statelessSession from weblogic example, but I got this error message when I tried 'ant run' command. My ant command works fine and I didn't change any directories.

are you sure you have deployed the EJB at the server?

it says:

Running the build script places the EJB in the %applications% directory, where it automatically deploys once the server is started. If you are already running the server and build another EJB, it is automatically placed in this directory and instantly deployed.

do I need to deploy manually?

It is always good to to a manual deploy. If the automatic deployment fails you would have to do it manualyl anyway.
