Did you include a package statement in your
UserData.java file? Something like
package org.apache.jsp;
?
If so, then the compiled class file needs to be in
/WEB-INF/classes/org/apache/jsp/

Re: JavaBeans
Could this be a package issue as well (see Tomcat can't find my
classes)? Classes places in the /classes folder must be in nested folders
matching the package name. When you reference this class, you must use the
package name, for instance:
jsp:useBean id=user class=mypackage.userclasses.UserData scope=session/

I sent like three responses to this yesterday.
I'll paste them in until people get sick of this, or this problem goes away.

From the error message, your class LogonData is part of the
org.apache.jsp packages.
If that is right, you will need to put the class file LogonData.class in c:
\tomcat\webapps\ROOT\WEB_INF\classes\org\apache\jsp
Sorry to be a pedant, but this is not true. Tomcat looks for classes that
don't have a package home in the tomcat default jsp package -- which is
org.apache.jsp . This is why you either need to explicitly import the
classes before you use them or put them in your own packages to avoid this
problem altogether.
See my answer of about 5 minutes ago.

you need to import the bean before you can use it - finally remembered this.
it's been discussed a lot on this list. i think -- or maybe i'm remembering
something else.
try making a line at the top of your jsp that says:
%@ page language=java contentType=text/html import=LogonData %
If you put your classes in packages this doesn't happen, AFAIK.

RE: JavaBeans
Hi Kavi, JavaBeans must be placed in the Web-Inf/classes directory of your webapp as long as they don't belong to a package and you don't set a classpath. Else you must create a directory structure similar to your package name, i.e. package: yourpack.com -- web-inf/classes/com/yourpak. Hope this helps Thomas
RE: JavaBeans
Hi Place the bean class either in the Web-inf/classes directory (along with the package directory structure) or package it in a jar and place it in the Web-Inf/lib directory. regards -Original Message- From: Kavi [mailto:[EMAIL PROTECTED]] Sent: Tuesday, May 29, 2001 7:13 AM To: [EMAIL PROTECTED] Subject: JavaBeans Hi everyone, I am trying to use my first javabean in a JSP using tomcat but where I must place the bean(or package??)
