How to enable el-api.jar ver. 2.2 in Tomcat 7 ?

[Dlugi Dlugiass]

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.
