[jboss-dev-forums] [Design of JBossXB] - Re: How to force strict validation?

[rob.stryker@jboss.com]

Hey Alexey:

I'm looking at the absolute latest JBoss XB (now, at least), specifically MarshallerImpl vs XercesXSMarshaller. 

It is plain to see (IMO) that MarshallerImpl does *not* throw any exceptions if a required attribute is missing. I just ran a test to verify.

I did manage to get one marshaller to throw such an exception (after slight modification). I took the XercesXSMarshaller's and added the following code starting at 695:


  |          } // end if attrValue != null 
  |          else if( currentAttribute.getRequired()){
  |         	 // its required and is not present. Must throw exception
  |         	 String name = currentAttribute.getAttrDeclaration().getName();
  |         	 throw new JBossXBRuntimeException("Required Attribute " + name + " is not present");
  |          }
  | 

Once I made this modification to XercesXSMarshaller, my test passed successfully. After reading your suggestion about MarshallerImpl, I switched to that marshaller, and the exact same test failed to throw any sort of JBossXBRuntimeExcepton of any sort for missing a required attribute. 

The test, plainly, is that my schema REQUIRES an attribute (such as "name") and I am trying to marshall an object lacking this attribute. 

Since I've found a workaround in my edits to XercesXSMarshaller, I can move forward with my project; but I think some similar functionality needs to be added to MarshallerImpl if you intend for it to replace XercesXSMarshaller. 

Hope all's well! Thanks for your help!
