Hi Gurus,


since few hours I`m trying to install el-api.jar ver 2.2 (el-api-2.2.jar) in my Tomcat. I deleted TOMCAT_HOME/lib/el-api.jar old version and copied new one.
After restart tomcat 7 showing me that error.

Should I configure something in web.xml ? Would be great if somebody could support me...

How to install el-api.jar in version 2.2 in Tomcat ?

I think you probably made a mistake in deleting the original el-api.jar from TOMCAT_HOME/lib. It's probably critical to Tomcat internal functioning.

Unless you were using a published recipe for upgrading to EL 2.2 that explicitly mentioned doing that as one of the steps, I'd restore the deleted jar.
 
It is sorta covered in the JavaRanch Style Guide.
