我的EJB应用程序没有部署在WebSphere上吗？

Question

I've tried installing an application onto a server and when the server tries to start the application, I am seeing an error in the log. The most relevant part of the stack trace appear to be

    000000ab SharedEJBRunt E   WSVR0040E: addEjbModule failed for BasicsJMSEJB.jar

I am having an enterpraise application and this EJB jar is added to my ear. I do not have any compilation error and build is also successfull through maven.I do have added log4j jar file as dependecy to this project. COuld you please help me where and what did I miss?

Answer 1

There are only two ways from your deployed application to find a dependent jar.

1 Include it correctly in the EJB jar itself. You should inspect the contents of your packaged EJB jar file to confirm that the log4j jar is in fact included. Use jar tf jar-file or winzip.

2 By adding the log4j JAR file as a Shared Library on the Websphere server instance. In which case it will be available to all applications deployed on the server instance.

If you are using Maven, ensure that you have not set the log4j dependancy to use the

<scope>provided</scope>

option. This option will not include the log4j jar in the packaged application.
