Hi
I am new to JSP. Could anyone plz tell as to how we include a jar file in the jsp. All I know is that we put it in WEB-INF/lib folder. But it does not fix my problem. If I write : <%@ page import = "WEB-INF/lib/*.jar" %> I get the following error in TOMCAT:
HTTP Status 500 -
--------------------------------------------------------------------------------
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
org.apache.jasper.JasperException: Unable to compile class for JSP
Generated servlet error:
E:\Tomcat\work\Catalina\localhost\RssHelper\org\apache\jsp\displaynews_jsp.java:10: '.' expected
import WEB-INF/lib/*.jar;
^
Generated servlet error:
E:\Tomcat\work\Catalina\localhost\RssHelper\org\apache\jsp\displaynews_jsp.java:10: unclosed comment

^
Generated servlet error:
E:\Tomcat\work\Catalina\localhost\RssHelper\org\apache\jsp\displaynews_jsp.java:128: <identifier> expected

3 errors
If I remove the import tag from the jsp, but have the jar in the lib folder, even then i get the following error:
HTTP Status 500 -

Actually, I want to include the xerces.jar file from apache in the jsp.

I am getting the same error (500) when I try to run a jsp that fetches server time. I am using java.util.Date package. It also says it cannot find out.write() even when I have not used it!
