JSP 500 Errors

[Nancy.Nicole]

I apologize in advance if my question is easily answered (I've never
used JSP before). However, I've tried to fix this problem for days and
nothing I do seems to work. Please help if you can. Before you ask, I
have the jar file in both the WEB-INF\classes and \javalib directories.
Also, they are in a subfolder (my useBean id). I've tried to research
this but can't find an answer that seems to work.
Here's the error:

exception

org.apache.jasper.JasperException: Unable to load class for JSP

I do not know if it is the cause of your problem, but jar files
should be in WEB-INF\lib !

If fixing that does not solve the problem, then you need
to post more info like code snippet and an overview of
files and directories.

Thank you for your response . This is my first time working with JAR
files. Is the *.jar file the only file that needs to go in the
WEB-INF\lib folder? The classes go in the WEB-INF\classes folder,
correct?

Thanks,
Nancy

class files goes on WEB-INF\classes\xxxx where xxxx
is the package of the classes.

Should the package be named the same as my jar file or does that
matter?

A Jar file might contain classes from many packages.
The name of the Jar is not connected with the name
of the package(s) it contains (though ideally, the Jar
name should be as 'meaningful' to the classes it contains).
