Re: NULL Pointer exception in BeanDeserializer

[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.
