Subject RE: java.lang.ClassNotFoundException with small jsp file
Date Wed, 31 Dec 2008 01:51:53 GMT

I can't seem to find where the log entries are for this problem.  The logs
that are under ...\Tomcat 6.0\logs don't have any entries for this problem.
I'm thinking that maybe, since I launched the Tomcat from eclipse, that it
changed the log location.  (But I don't know where it is)

Both the class file and the java file exist in the specified folder.  I even
deleted them and they were re-created by the application server.

I gave full permissions to Everyone for the directory:
C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\work

This actually fixed a previous problem I had with a compilation problem.

I'm thinking that it's some variable that I didn't set but the installation
didn't ask for anything like this and the example jsp applications work
fine.

Is there any error messages before this in the logs that might offer any
further insight?  

When you say the class file exists, do you mean there
is both hello_jsp.java and hello_jsp.class?  Or is the .class file
missing.  Lastly, are you sure the user tomcat is running as has read
privilege to the file?
