class loaded wrong

[Huaxin <hx...@cs.ualberta.ca>]

I am moving my 3.2.3 application to 4.0.1, and it
failed to work

my jsp file uses a bean which is defined under WEB-INF/classes
(without package)

say that class is MyBean.java, the error log shows

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

An error occurred at line: 4 in the jsp file: /process.jsp

Generated servlet error:
D:\henry\jakarta-tomcat-4.0.1\work\localhost\survey\process$jsp.java:61:
Class org.apache.jsp.MyBean not found.


Must I define all classes inside a package?

Thanks Craig for the info.  You do a great job with the TC 4 development and 
answering questions on the list!

I kind of thought of that after I sent the email but I did the method below 
as a fake, fudge, and cheat method in a learn-as-you-go experiment page.  
Some time soon I'll have to take the time to learn the class loading scheme 
and how to use it right. :-)

Back to reading the docs for me.....

To use a class that is not in a package, you have to specifically import
it in a <%@ page %> directive.  However, you should know that this is
likely to cause you portability problems -- you are much better off using
fully qualified bean names in packages.

I've done this in one of my JSP pages and all I did was import the class.  
Only specified the class name itself (no org.whatever....) and placed the 
.class file in the WEB-INF/classes directory.  You do need to compile your 
class though with javac or equivalent.

I'm using Tomcat 4.0.1.
