New To JSP

[Bal Sharma]

Hello Everybody:
I am using tomcat 4. Among the JSP sample example only Number guess is working. I tried to run rest of the sample examples but I got following errors. What is going on? I am new to JSP and Servlet. Please tell me how to fix it?
A Servlet Exception Has Occurred
org.apache.jasper.JasperException: Unable to compile class for JSP if (pageContext != null) pageContext.handlePageException(t);

i got the same problem too when I installed Tomcat 4. All along I have been using Tomcat 3.23 and I have had to stick to it because it works. Apparently there is something that we don't know about Tomcat 4 and maybe the experts will tell us why this error comes up one day. By the way I also posted the same question about Tomcat 4 about 2 weeks ago and nobody answered me. So my advise is that you should isntall Tomcat 3.23 and it works real good.
