PM66000: differently named uri path template variables in jax-rs subres

APAR status

• Closed as program error.

Error description

• Consider the following resource class:
  
  @Path("/books")
  public class MachineCollectionEntity  {
  
   @GET
   @Path("/{bookTitle}")
   public Response getBookByTitle(@PathParam("bookTitle") String
  bookTitle) throws Exception {
    ...
   }
  
   @POST
   @Path("/{isbn}")
   public Response addBookToCollection(@PathParam("isbn") String
  isbn) throws Exception {
    ...
   }
  }
  
  Depending on the order of the methods, either the bookTitle or
  isbn parameters will be null, even though the path parameter
  specified in the request is non-null.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  Application developers of JAX-RS services   *
  *                  specifying URI path template variables on   *
  *                  subresource methods, running IBM WebSphere  *
  *                  Application Server V8.0 and V8.5.           *
  ****************************************************************
  * PROBLEM DESCRIPTION: Subresource methods (meaning, methods   *
  *                      with an @Path annotation implemented    *
  *                      within a resource class) can use        *
  *                      variables in their Path value. If       *
  *                      subresource methods have differently    *
  *                      named URI path template variables,      *
  *                      such as what is shown in the previous   *
  *                      example, the parameter that is passed   *
  *                      into the subresource method might be    *
  *                      null.                                   *
  ****************************************************************
  * RECOMMENDATION:  Install a fix pack that contains this       *
  *                  APAR.                                       *
  ****************************************************************
  Subresource methods (meaning, methods with an @Path annotation
  implemented within the resource class) can use variables in
  their Path value. If subresource methods have differently
  named URI path template variables, such as what is shown in
  the example, the parameter that is passed into the subresource
  method might be null.
  For example, using the same example, if the application tries
  to print the value of the isbn parameter, you might observe
  that it is null, when the path parameter specified with the
  request URL is not null.
  

Problem conclusion

• The JAX-RS engine was corrected to process each subresource
  method's URI path template variable, if present.
  
  The fix for this APAR is currently targeted for inclusion in
  fix packs 8.0.0.6 and 8.5.0.1.  Please refer to the Recommended
  Updates page for delivery information:
