Tomcat 7 javax.el.ELException

I restarted the httpd and tomcat service today, and after doing so. I was greeted with the following message.

I saw this thread http://www.coderanch.com/t/592922/Tomcat/enable-el-api-jar-ver

And did as they told. I checked, and the el-api.jar is there. I checked another server, and tomcat is running great with it as well.

The server is a Centos 6.4 (final) and Tomcat 7.0.23.

I tried everything, even replacing the jar files, but nothing seems to work.

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.

I got the same error today on Tomcat 9.0.21

and as per this bug - https://bz.apache.org/bugzilla/show_bug.cgi?id=64097

It is a known bug with "el-api.jar" and has been fixed in following versions

Fixed in:

  • master for 10.0.0.0-M1 onwards
  • 9.0.x for 9.0.31 onwards
  • 8.5.x for 8.5.51 onwards
  • 7.0.x for 7.0.100 onwards

Solution :- You can upgrade tomcat to these versions or just bring over the "el-api.jar" from the lib folder of a newer tomcat (which has the fix), place it in your lib folder and restart tomcat. It would work.

Please, make sure you have both these jars at ${TOMCAT_HOME}/lib

el-api-2.2.jar // jar version could differ
el-impl-2.2.jar
