Weblogic.ejbc error

[Dhirender Kumar Thakur]

Hi All,

I am learning EJB and trying to deploy a stateless session bean. I have compiled all the java files and created test.jar(contains .class files and META-INF/.xml files) file.

When I am executing the command java weblogic.ejbc test.jar final.jar, following errors are shown:

<Warning> <EJB> <BEA-010054> <EJB Deployment: stat
elessSession has a class TraderBean that is in the classpath. This class should
only be located in the ejb-jar file.>
<Warning> <EJB> <BEA-010054> <EJB Deployment: stat
elessSession has a class TraderHome that is in the classpath. This class should
only be located in the ejb-jar file.>
<Warning> <EJB> <BEA-010054> <EJB Deployment: stat

EJB.>

ERROR: Error from ejbc: Compiler class: 'com.sun.tools.javac.Main', not found


ERROR: ejbc couldn't invoke compiler

How can I rectify these errors. Please guide me. I have included the weblogic.jar file in classpath.

Thanks in advance.

To get rid of the warnings you need to remove the ejb classes from the server classpath.

To fix the classdefnotfound problem you should probably add tools.jar from the jdk to the classpath.

Hope this works.

I had this same problem when building my EJBs using Ant. I added "-compiler javac" to the weblogic task and it fixed the problem:

<weblogic destdir="${JAR.DIR}" args="-nowarn -compiler javac" ejbcclass="weblogic.ejbc">
<wlclasspath>
<path refid="ejbc.classpath"/>
</wlclasspath>
</weblogic>
