You said you were using Struts 1.2.7. I'm guessing those 1.1 TLDs are declaring the TEI class Tomcat's failing to load in the old location. Try using the TLDs (and other configuration files) that correspond to the Struts release you're using.

Hi Laurie,

Thanks for your answer.  I did a quick search to find if that
was my problem and unfortunately it isn't.  I don't have any other
copy of struts.jar in any other directory than in my project directory (WEB-INF/lib)... 

Here is the struts structure I have:
WEB-INF/struts-bean-1.1.tld
WEB-INF/struts-bean.tld
WEB-INF/struts-html-1.1.tld
WEB-INF/struts-html.tld
WEB-INF/struts-logic-1.1.tld
WEB-INF/struts-logic.tld
WEB-INF/struts-nested-1.1.tld
WEB-INF/struts-nested.tld
WEB-INF/struts-tiles-1.1.tld
WEB-INF/struts-tiles.tld
WEB-INF/lib/struts.jar

I just hope this ok.  Thanks again for helping me.  This is really strange
since I have been able to use struts without any problem on older Tomcat
version.

Thanks,
Christian Dionne

You probably have multiple copies of the struts jar on you application's class path. Make sure that struts.jar only exists in your WEB-INF/lib directory and not elsewhere in whatever application server or servlet container you're using. Assuming you're using Tomcat, look for copies of struts.jar in common/lib, shared/lib, etc.

Hi!

I'm using Tomcat 5.5.9 with Struts 1.2.7.  I am trying to convert my
application that was working
fine with Tomcat 5.0.30.  I mostly fixed everything except that now I am
getting this error.

This occurs when parsing a .jsp file that includes a struts .tld.

Any idea how to fix this?  I saw a lot of similar post on the internet
