RE: NULL Pointer exception in BeanDeserializer

2005-04-13 Thread Simon Fell
That would refer to a local definition of a type called anyType, it
probably should be referencing the XML schema type anyType, e.g.

I'm a little leary of this definition in the schema:


  

  


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

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,




Re: NULL Pointer exception in BeanDeserializer

2005-04-13 Thread Ramesh Vijayaraghavan
This is the WSDL file of the .NET service provider that I am using. I am 
wring an Apache Axis Java Client to access a .NET web service provider. I am 
trying to invoke the GetLaunchInformation web service and I am getting a 
NULL pointer exception in the BeanDeserializer. see my earlier emails. The 
input is a user name( in the following format DOMAIN/USERNAME)

And the interesting part is that  output is an array of anytype and an error 
string. The internet is full of information about the problems with array of 
anytypes as output.

Also I generated the java stub files using WSDLtoJava and the array of 
anytype uses BeanSerializer and Bean Deserailizer as its serializer and 
deserializer. Shouldn't it be using Array Serializer and Array Deserializaer 
instead? These files were autogenerated. so won't WSDLto java know what type 
of serializer to use.

Are there any caveats for the Array of Anytpe for .NET interop with Axis 
java client.

Any help is appreciated.

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,

   // was NOT the ArrayDeserializer, this is a non-SOAP array:

Re: NULL Pointer exception in BeanDeserializer

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
