Please resend this email to users_at_jersey.dev.java.net. The WADL generation
code in Jersey is not part of the wadl.dev.java.net project codebase.

Thanks,

Marc.

Subject: WadlGeneratorResourceDoc NullPointerException

Hello,

I’ve just updated jersey version to 1.3 and I’m facing a curious behavior
generating extended wadl.

Using the wadl-resourcedoc-doclet maven task to write the wadl to a file I
just had to change xercesImpl to version 2.8.1 and it works fine.

But when starting the server (tomcat 6) I have this error:

java.lang.NullPointerException

      at
com.sun.jersey.server.wadl.generators.resourcedoc.WadlGeneratorResourceDocSu
pport.createParam(WadlGeneratorResourceDocSupport.java:325)

      at
com.sun.jersey.server.wadl.WadlBuilder.generateParam(WadlBuilder.java:260)

com.sun.jersey.server.wadl.WadlBuilder.generateResource(WadlBuilder.java:282
)

com.sun.jersey.server.wadl.WadlBuilder.generateResource(WadlBuilder.java:265
)

      at
com.sun.jersey.server.wadl.WadlBuilder.generate(WadlBuilder.java:101)

In fact “_delegate.createParam( r, m, p );” line 320 of WadlGenerator class
return null.

The resource, the error appends on, has those annotations:

      @POST

      @Consumes(MediaType.APPLICATION_FORM_URLENCODED)

      @Produces( { MediaType.TEXT_PLAIN })

Public Response stuff(@FormParam("stuff") Integer stuff1, ….)

My maven dependencies:

                <properties>

                               …

I’m looking for a solution if you can help me.

Thank you in advance.
