problem deploying jsps with tomcat

[Ryan]

The only java beans I can get to work are the ones that come in the example
directory.

I made a simple jsp and put it in the 'cal' package under the examples
directory. It works fine if use the TableBean that comes with tomcat as
follows:

<jsp:useBean id="table" scope="session" class="cal.TableBean" />

If I save TableBean as TableBean2.java and I only change the class name and
the constructor to TableBean2 and recompile, I then use the following to
call it in my jsp

<jsp:useBean id="table" scope="session" class="cal.TableBean2" />

I get the following set of errors: I get these errors everywhere I use a
bean I create. I do not get errors when I use the default beans. Is there a
configuration parameter i need to set? I don't see it in any books.

I think you got a tomcat configuration error

I ran into a problem similar to this, what I did wrong is that my
tomcat is run by a JVM older than java Compiler that I used.

What I would do, is install java and tomcat from scratch and try it
again.

hope this help

So how, precisely, did you compile it? If I was in the cal subdirectory
then I would issue the following command:

javac -d .. TableBean2.java

looks like the compiled class file is not in the right classpath. please
make sure that you have the TableBean2.class somewhere in the classpath as
"cal/TableBean2.class". Or you can put the class in a jar file and put the
jar file in the class path.
