Title: RE: InstantiationException in Tag Extension Tutorial, Lesson #3

Magnus,

 

Thanks for the prompt reply. I fixed the typo, but my problem remains. How does JSP decide where to look for classes? I've been unable to get my jsp files to find classes in jar files.

For example, if I put hello.jsp and mytags.jar (from Lesson 2) directly under orion/default-web-app, I get "The page cannot be displayed". Yet I can run the example JSPs OK.

Similarly, Lesson 3 says to put connection.jar into orion/servlets, but as far as I can tell it's ignored unless I put it in orion/lib, and I got farther by moving the class tree directly to orion/default-web-app/Web-Inf/classes. What is correct?

 

James

James,

im very sory for this typo, but under "Update the Tag Library Descriptor", step 2, make sure that the name of the iterate tag is <name>iterate</name> with a lowercase 'i'.

I will try to update the online docs asap.
It has been fixed before, so Im quite bewildered at it reappearing..

Hello all,
I'm getting the same error that David Geary was getting a few weeks ago,
when I get to the end of Lesson 3 in the Tag Extension Tutorial.
My ContactLister.jsp is directly from Orion's website. What could I be doing
wrong?
Incidently, I could only get this far by putting my connections.jar in
/orion/lib, not in /orion/servlets, as it says in step 4 of "Create some
Beans".
If I do put it in /orion/servlets I get "java.lang.NoClassDefFoundError:
com/acme/connections/Company".
Thanks for any light that might be shed on this problem,

James McMullen
