I am getting this error randomly. I am getting this error any time and if i restart my tomcat it goes away!!!! I am not getting this error in my local system but i am getting this error when i run my project on web-server.

[This](http://stackoverflow.com/q/7837576/1285418) might help — Pau Kiat Wee, May 28 '12 at 08:45
Du you use it in a multi-thread environment? Concurrent access of more than one thread can randomly provoke errors. — Johanna, May 29 '12 at 08:46

The error is because you have multiple different version of JSTL libraries in classpath.

You can remove:

standard.jar
standard-1.1.2.jar
jstl-1.1.2.jar
jstl.jar

Sorry, no: containers are not guaranteed to provide JSTL. If you are using Tomcat and want JSTL, you'll have to provide it in your webapp's WEB-INF/lib directory. Be sure not to have JSTL libraries in Tomcat's (server) lib/ directory as well. – Christopher Schultz May 29 '12 at 21:06
I would like to add that in my case I get that error as I have jstl-1.1.2 and jstl.jar, both together does not work well also seems that jstl.jar contains some standard.jar stuff – Koitoer Feb 24 '17 at 21:43

deferredExpression error mostly comes due to duplicate or same jar with different versions jars in you applications. If you will remove those conflicts it will not shown up again
