Hi everybody,

I have 2 questions regarding WebServices DataTypes:

1. Problem with String Arrays

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

/**
 * @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:

...
- <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:

/**
 * @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...

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

This just shows a 0. What is the problem with this ?? testint.Length returns the correct array size of 3.

Thanks
matt
