Hi everybody,

I have 2 questions regarding WebServices DataTypes. I'm using Jboss 4.0.0DR4 and a C# Client.

1. Problem with String Arrays

I created a function in J2EE exposed as a web-service that returns a string array to the caller:

Code:
/**
* @jboss-net.web-method
* @jboss-net.wsdd-operation
* @ejb.interface-method view-type = "remote"
*/
public String[] testStringArray(){
String s[] = {"test","string"};
return s;
}
 


When I call this function in a C# Client - I get an System.InvalidOperationException that states that there is an error in the XML-Document.

Part of the WSDL looks like this:

Code:
...
- <complexType name="ArrayOf_xsd_string">
- <complexContent>
- <restriction base="soapenc:Array">
  <attribute ref="soapenc:arrayType" wsdl:arrayType="xsd:string[]" />
  </restriction>
  </complexContent>
  </complexType>
...
  <wsdl:message name="testStringArrayRequest" />
...
- <wsdl:message name="testStringArrayResponse">
  <wsdl:part name="testStringArrayReturn" type="impl:ArrayOf_xsd_string" />
  </wsdl:message>
 


If I transfer an int-array everything works fine. Does this have something to do with the way XDoclet generates the WSDL-file ?? Or is this a fault of the WSDL generator from Microsoft.


2. Accessing Array content in C#

If I transfer an int-array everyting works fine:

Code:
/**
* @jboss-net.web-method
* @jboss-net.wsdd-operation
* @ejb.interface-method view-type = "remote"
*/
public int[] testIntArray(){
int i[] = {10,20,30};
return i;
}
 


but on the C# site I can't figure out how to access the content of the array...

Code:
...
int[] testint = stub.testIntArray();
Console.WriteLine(testint[0]);
...
 


The output is 0 - which should be 10. What is the problem with this ?? testint.Length returns the correct array size of 3.

Thanks

Unless these are document/literal .NET will not understand the binding, or will have interop problems. Is there any way to instruct jboss to generate document/literal binding?

I think I read something about changing the style of the message. But would this constraint only apply to array types ??

I don't get any problems when exchanging simple Types like String, int, double, boolean etc. Furthermore it works fine to transfer BeanObjects and Arrays of Beans (Jboss uses AXIS and AXIS implements a BeanSerializer/DeSerializer).
