Description

« Hide

Hi,

I have been using the displaytag v 1.0-b3 jar for my application and it was properly working on BES
(Borland) app server since the last 2 years :)

When I migrated my application to Websphere App Server, it gave me an exception in the logs which reads
like:
javax.servlet.ServletException:
org/displaytag/tags/TableTag

The error doesn't say much about the root cause which is why I have been breaking my head over this for the last couple of days, albeit with no gains :(

Has anyone encountered this error ? From the above exception, looks like the jar file is being loaded properly.

Any pointers would be much appreciated.

TIA,
Kirti

I have the same problem when I try to deploy my portlet project with displaytag to our WebSphere Portal 5.0 build server. In WebSphere TE all is ok. There are no messages in portal log except this one: org/displaytag/tags/TableTag.

an error message like org/displaytag/tags/TableTag means that the classpath is missing some of the classes displaytag depends on. Please check if the needed jars (commons-lang, commons-logging, etc) are properly deployed
