Hi,

I wrote a new Catalog Entry EJB (JansCatalogEntryBean) using VisualAge for Java 3.5.3. I added a JansCatalogEntryAcessBean. Then I exported an EJB JAR and put it in the depoyableEJBs directory in IBM WebSphere Application Server.

In WAS Admin Console, I added this EJB to the WCS EJB Container. Then I have a WCS command which I wrote. When this command tried to new a JansCatalogEntryAccessBean, error 500 occurred. The error message was:
Server caught unhandled exception from servlet [WCS Request Servlet]: com/ibm/commerce/janscatalog/objects/JansCatalogEntryAccessBean

In the wcs.log, I found these lines:
[02.03.19 17:49:08:119 CST] 509701c ServletInstan X Uncaught service() exception thrown by servlet {0}: {1}

Could anyone please suggest to me what's wrong there? Thank you for your help.
