OK, I am running JRun 3.0 on Redhat 6.2. I have JRun installed under the
default directory of /opt/JRun and I have jdk1.2.2 installed under
/usr/local/jdk1.2.2
I just added in my version of the CLASSPATH and my servlet is working again.
Here is what I used for a CLASSPATH.
CLASSPATH=.:/usr/local/jdk1.2.2/lib/tools.jar:/opt/JRun/lib/jrun.jar:/opt/JR
un/lib/jsp.jar
I have no idea of my CLASSPATH is correct or not, since I can only guess
what my required libraries are. Since it works again maybe the above was a
good guess.
I will try running in Netscape and see what happens as you suggest.
10 minutes later:
OK, now its giving me that error again after recompiling. It looks like
something is wrong with how the servlet knows about the bean I am using.
Below is the error that I get in both IE 5.0 and Netscape 4.72.
shopping.Item I assume is the line import shopping.Item; from the servlet.
500 Internal Server Error
/rhii/servlet/ShopServlet:

Subject: Re: Compiling your beans...
Ah, I see the problem, the lines get cut off :-)
I am attaching a text file with the two classpath lines in it...
The line that starts with 'jar' should actually be a part of the line above
it.
This classpath only works for Linux or Unix and only works with Resin 1.1
that has been installed in /usr/local/resin1.1.
What servlet engine are you using? What platform (Windows, Linux) are you
running it on?
When you say that you are getting an error, what kind of error? If it's a
500 Servlet Exception or just a 500 then there is an error in your code. If
you are using Internet Explorer, it very hard to find out where the error
is. If you use Netscape as your browser, you'll get lots more information
about the error (which will help you find it). As well, you might want to
turn off JIT. JIT compiles your code. If your code isn't compiled it'll
run a little slower, but you'll get the line number of the error in your
error 500 message!!! If you want to turn off JIT, simple add:
set JAVA_COMPILER=NONE
to your autoexec.bat file if you are running your servlet engine under
Windows
If you are running Linux, add:
JAVA_COMPILER=NONE
export JAVA_COMPILER
to the .bashrc file in your home directory.
Hope this helps,
Donald
