If it was working fine earlier and suddenly stopped working, something must have changed in between.

May be your web.xml instructs the container to ignore EL. (See under <jsp-config><jsp-property-group> element. <el-ignored>true</el-ignored> .

Make sure your new file is part of the same web-application the old one was part of.

i have not changed anything.there is no <jsp-config> tag in my web.xml.Since this is part of my exam prep the web-app issue is not there.

I too had the same problem while learning Expression Language. EL is enabled by default. This is what I learned. At first, when learning I did not have any <el-ignored> entry in the web.xml. I was surprised to find that el was not evaluated. Then I put in an entry to eveluate EL in the DD. Even after that the EL was not evaluated. Then the last thing I added an entry to evaluate EL in the jsp page. Huh! It worked. The EL in the page was getting eveluated. I really dont understand why the EL was not evaluated when there was an entry in the DD.

Check whether jstl.jar and standard.jar are present in your web application's web-inf/lib directory.
