problem in compiling with Jbuilder

Hi,

I'm using Jbuilder9 for editing the .Par files and getting lots of error message, like

1.package com.sapportals.htmlb.page does not exists.

2. cannot resolve symbol: class PageProcessorComponent

etc.,

basic thing what I understood is that its not identifying the import packages. Is it anything to do with the classpath?

I have installed tomcat in c:\tomcat and jbuilder in c:\jbuilder9 and jdk in c:\jdk1.3.1_09.

PDK documentation shows JCo.jar file in c:\tomcat\libs\apps but I don't see it in the specified directory. Pl. suggest me in this.

Thanks in advance.
