Migrating from Websphere

craig_perring Oct 5, 2004 2:50 AM

I am in the process of evaluating JBoss as a possible replacement to Websphere. I have an existing application that uses JSP tags, JMS, EJBs etc. So far I have managed to get a test app up that uses a datasource to access my database and uses JMS to get/put to a Websphere MQ queue.

No problems yet.

I have also managed to deploy my existing application so that JBoss starts up without any errors. However when I access a jsp that uses tags I find that the tags are duplicating the HTML that is produced. Subsequent refreshes on the page causes the duplication to double, triple etc. This carries on until I restart the JBoss server at which stage it all starts over.

Has anyone encountered this bizarre behaviour before? The application runs perfectly under Websphere.

I think I've found my problem. It concerns the "enablePooling" init-parm of the org.apache.jasper.servlet.JspServlet. I have changed the init-parm in my jboss-3.2.5\server\default\deploy\jbossweb-tomcat50.sar\web.xml file but the apache instance in JBoss still appears to be pooling the Tags.

Any ideas?

Silly Me. I needed to delete the compiled JSPs. All good now. Thanks for all your help
