Issues deploying application on websphere 7

I am getting problems starting my application on Websphere 7.

The application has jsp, jspx files.

The application works fine on tomcat. However when I try to start application on web sphere 7, I get following errors in the logs

I checked the tld files in web.xml and they all exist.

Any idea what can be the problem ?

---

I recently encountered this exact same error and it turned out to be some invalid elements defined in the TLD XML. I compared the TLD I was given against the DTD it declared to be valid against and noticed some discrepancies. Also, WebSphere did not like that <info> had embedded HTML tags in it. Fixing those problems eliminated this exception.
