Re: NULL Pointer exception in BeanDeserializer

[Ramesh Vijayaraghavan]

Thanks Peter, Line 282 falls somewhere in the comments section in the 
source. Can somebody provide some information if this issue will be fixed in 
the stable release. Any workarounds are welcome.

Thanks,
   // Register value target
   if (propDesc.isWriteable()) {
   // If this is an indexed property, and the deserializer we found
   // was NOT the ArrayDeserializer, this is a non-SOAP array:
   // bean
   //   fieldvalue1/field
   //   fieldvalue2/field
   // ...
Line 282   // In this case, we want to use the collectionIndex and 
make sure
   // the deserialized value for the child element goes into the
   // right place in the collection.
   if (propDesc.isIndexed()  (
   !(dSer instanceof ArrayDeserializer) ||
   propDesc.getType().isArray())) {
   collectionIndex++;
   dSer.registerValueTarget(new BeanPropertyTarget(value,
   propDesc, 
collectionIndex));
   } else {
   // If we're here, the element maps to a single field value,
   // whether that be a basic type or an array, so use the
   // normal (non-indexed) BeanPropertyTarget form.
   collectionIndex = -1;
   dSer.registerValueTarget(new BeanPropertyTarget(value,
   propDesc));
   }
   }

   // Let the framework know that we need this deserializer to complete
   // for the bean to complete.
   addChildDeserializer(dSer);

Also, please note that his looks like an array within an array, Array of 
variables enclosing an Array of anytype. Is this WSDL definition corrrect?
Thanks,

That would refer to a local definition of a type called anyType, it
probably should be referencing the XML schema type anyType, e.g.

s:complexType name=ArrayOfAnyType
  s:sequence
 s:element minOccurs=0 maxOccurs=unbounded name=item
type=s:anyType nillable=true /
  /s:sequence
/s:complexType 

Cheers
Simon

 I'm a little leary of this definition in the schema:
 
 s:complexType name=ArrayOfAnyType
   s:sequence
 s:element minOccurs=0 maxOccurs=unbounded name=anyType
  nillable=true /
   /s:sequence
 /s:complexType
 
 This defines an *element* named anyType (rather than a 
 *type* named anyType), which I suspect could cause a lot of 
 confusion.
 
 I would suggest changing it to 
 
 s:complexType name=ArrayOfAnyType
   s:sequence
  s:element minOccurs=0 maxOccurs=unbounded 
 name=item type=anyType 
  nillable=true /
   /s:sequence
 /s:complexType

A bug detection tool I ran recently identified a possible null pointer 
dereference in this very method. (line numbers don't match exactly but I 
was using 1.2beta3 source code).

The problem detected by the tool related to an unguarded dereference of 
the 'dSer' local var:

   dSer.registerValueTarget(new BeanPropertyTarget(value,
   propDesc, collectionIndex))
Unfortunately, I am not at all familiar with the Axis code, nor how your 
scenario has caused this problem, but at least now that there is 
apparently a *real* user problem I hope my earlier bug report may be 
taken a bit more seriously ;-)

See http://issues.apache.org/jira/browse/AXIS-1924

I am passing an input parameter with a forward slash like

This is when I see this exception.
