I am getting some errors during I build my project.
If I use taglib, Do I need to download jstl.jars ?
Please suggest me
You need to download the JSTL 1.1 or 1.0 core taglibs and put the jars in a place where your webapp can reach them. (Make sure you have the version that matches the servlet spec for your app server) for example you are using tomcat, so you will want to put the files in TOMCAT_DIR\common\lib so all webapps can use these taglibs.
Note: that there are two jars in the zip package that you need: "jstl.jar" and "standard.jar". To make it work put them both in the common\lib directory and it should work. OR you can put them in your WEB-INF\lib so it will be more portable with your .war file..
