Hi all,
I'm using one of AjaxTags's tag in my jsp page. When deployed in Tomcat 5
it runs fine, but under Equinox environment it throws the following
exception:
java.lang.ClassCastException: org.ajaxtags.tags.AjaxHtmlContentTag cannot
be cast to javax.servlet.jsp.tagext.Tag

I was wondering if there is any difference between JSP compiler used in
Equinox and Tomcat 5.
Any help would be greatly appreciated.

Simon,

I only have one jsp that imports this ajaxtags.

Actually the ajaxtags is not packaged as an OSGI bundle, I include it only
for internal use of one bundle certain and not to be exported.
Does packaging the ajaxtags as bundle will make a difference instead ?

Could you elaborate more on this ?
Best Regards,
Setya

Hi,
To clarifiy a few things a bit:
1. When deployed in Tomcat 5, the app wasn't deployed as OSGI app, just
plain web app.
2. The AjaxTags framework only used internally by a bundle, I put its jars
and dependencies in folder /web/WEB-INF/lib and put the reference to these
jars in my MANIFEST.MF under Bundle-ClassPath segment. So I don't package
this AjaxTags as separate bundle.
Best Regards,
Setya
