EJB API Deployment

Mullin · September 19, 2001, 5:20pm

I’m trying to use SUN J2EE Reference Implementation, and I’ve followed the documentation step by step, and then after setting up the classpath, I don’t know how to run the application.

Then, I tried to use the deploytool to deploy the application. Since I’m not very good at that, does anyone have a detailed documentation for this part.

By the way, do I need to use the Sun’s Deployment tool to deploy a ear file? How can I run the example provided, like Telephone.

Thanks for your help.

I can deploy it and run the application, but I faced an error - getConnection failed. Any ideas on this?

D:\ejb>runclient -client Telephone.ear -name TelephoneClient

I found another clue regarding my problem:
No suitable driver.

But, I think I’ve followed the installation procedures to add driver and database. And you can view from below that there’s already a binding

When I looked into EjbClient.java, and I found out BeansJNDIName is “DemarcatedTelephone” by default if we didn’t pass anything.

But, is it correct to change it to
“java:comp/env/ejb/DemarcatedTelephone” or
“java:comp/env/DemarcatedTelephone” depending and then basic on this value, we type it on the deployment tool.

I’m not sure whether it’s related to my stated problem or not.

Sorry that I’m not familiar to use ANT to recompile all the application. It would be great if someone can give me the build.xml to help compile all the java files.

Thanks!

Finally, I got it working. It’s due to mis-configuration of environment.
