Weblogic. ejbc error

[DhirenThakur]

Hi All,

I am learning EJB and trying to deploy first stateless session bean on
weblogic 8.1 server. I have created the different files in required
directory structure format. I have compiled all the java files and
created a test.jar file with all the contents.

I have included the weblogic.jar file in classpath. Now when I am
executing the command java weblogic.ejbc test.jar final.jar following
errors are shown:

<Warning> <EJB> <BEA-010054> <EJB Deployment: sta
telessSession 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: sta
telessSession 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: sta

<Warning> <EJB> <BEA-010202> <Call-by-reference i

descriptor for this
EJB.>

What should be done to rectify these errors.

Thanks in advance.
