Hi

Just playing with the WTP contributions...
Firstly followed instructions verbatim in the docs...

1. Set up Tomcat 4.1 (in preference to 5.0)
2. Created Convertor Project (Dynamic Web Project)
3. Selected Create Web Services
4. Selected the Tomcat 4.1 installation etc etc.

Then get an error

java.lang.NullPointerException

This is different from other posted problems (mainly due to Tomcat 5.0 and
arrangement of
directories.

Any ideas???

I will mention that the system is on a mac OS-X - latest version and
updates and uses 1.4.2 java
I use that mac as it is the only system that I do not have to reboot and
reload every 3 months!!!

Hi,

I believe you are trying to generate a Web service from a Java bean. Can you
double check that the Java bean you selected (in the 2nd page of the wizard)
is loadable from the service project you selected (in the 3rd page of the
wizard)?

For example, if you have a Web project called "wp" that contains a Java bean
called "test.MyBean", but you didn't pick "wp" as your service project, then
you may run into this error. In any event, there should be better error
handling, I'll submit a fix for it.

The URL is: http://www.eclipse.org/webtools/index.html.

Go to the bottom of the page and you'll see under the Initial Code
Contributions section, a file called ibm.zip and on the same line "Getting
Started Guide". Click on that link and you'll get to the documentation on
how to get started with the various components contributed by IBM.
