Hi,

 

I figured out what was wrong with this. It had to do with how I was
generating my jar file.

 

I changed this

<jar basedir="${classes.dir}/${package.dir}"
destfile="${service.dir}/stage/rs.jar" />

 

to this

<jar basedir="${classes.dir}" destfile="${service.dir}/stage/rs.jar" />

 

So, the root resource file was being found in the jar file, but it
couldn't be loaded as the jar file did not contain the package
information.

 

Also, these notes from Paul Sandoz are necessary as far as jar files
you'll need:

 

"See here [1].

 

In the taskdef you need to include all the jars mentioned in the Tools
section of [2] as well as the core set of jars.

In the WADLGenerate you need to include *only* your application
classes/jars.

Thanks,

Dave

Subject: ant WadlGeneratorTask help

 

Hi,

 

I'm having a bear of a time getting WadlGeneratorTask to work. Here's
my ant and the error I'm receiving. It finds my root resource, but
cannot seem to load it. I've tried several different ways to affect my
classpath, but none seem to fix this problem. Is there something I'm
overlooking and does anyone have a working example I could look at?

 

Thanks in advance for any help,

Dave
