infopath-problem: integrate webservice with complex datatype return

[tine]

Hello,

I created a simple axis-java-webservice by writing

1) a Server-Class (Skeleton):

package myPflanzenschutz;

public class PflanzenschutzNameServer {
public String[] getPflanzenschutzNamen()
{
String[] p = new String[3];

p[0]="erster Pflanzenschutz";
p[1]="zweiter Pflanzenschutz";
p[2]="dritter Pflanzenschutz";

return p;
}
}

2)a wsdd-file (server-config-wsdd) with the following service-tag:

<service name="Pflanzenschutz" provider="java:RPC" style="document"
use="literal">
<parameter name="className"
value="myPflanzenschutz.PflanzenschutzNameServer"/>
<parameter name="allowedMethods" value="getPflanzenschutzNamen"/>
<parameter name="scope" value="Session"/>

<operation
name="getPflanzenschutzNamen"
xmlnsperNS="http://develop2.fh-bingen.de:8080/axis/services/Pflanzenschutz"
qname="operNS:getPflanzenschutzNamen"
returnQName="operNS:getPflanzenschutzNamenReturn"
returnType="ns:ArrayOfString"
xmlns:ns="http://soapinterop.org/xsd">
</operation>

<typeMapping
xmlns:ns="http://soapinterop.org/xsd"
qname="ns:ArrayOfString"
type="java:java.lang.String[]"
serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
/>
</service>

If I call the service from my Client, everything works fine. But there
is a problem using the service in Infopath:

PROBLEM:

I created a form with datasource in infopath, and choose a webservice
as datasource. After that I choose, that the webservice only retrieves
data (not sends data). After that, Infopath asks me about the adress
of the datasource/webservice:
this is
http://develop2.fh-bingen.de:8080/axis/services/Pflanzenschutz?wsdl.
After that, Infopath shows me the methods which are contained in the
webservice and tells me to choose one of them. my webservice has only
a single method "getPflanzenschutzNamen", so I choose the method.
Now the Infopath-Error occurs:

Infopath tells me: ERROR:

/schema/element[1][@name= 'getPflanzenschutzNamenReturn']
xsd-type: '{http://soapinterop.org/xsd}ArrayOfString' is not declared

Now my questions:
- is there an error in my wsdd-file?? I think there is not, because my
own client (java-client, not infopath) works fine
- or is infopath not able to receive string-arrays or other complex
datatypes?

thanks for help!
