Hi
I need to develop a web service with Message broker (toolkit v.5.0.7) and I have developed a message flow with:

HttpInput->Compute->HttpReply

The compute code is:

Code:

CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
SET OutputRoot = InputRoot;
SET OutputRoot.MRM.*:Body.*:http.HTTPInputBody.OutputData.Data = 'xxxNEWDATAxxx';
RETURN TRUE;
END;

I have created a message definition file importing this xsd file:

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema targetNamespace="http://www.mrmnames.net"
xmlns:mrm="http://www.mrmnames.net"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:complexType name="HTTPMessageType">
<xsd:sequence>
<xsd:element name="URL" type="xsd:string"/>
<xsd:element name="InputData" type="mrm:DataType"/>
<xsd:element name="OutputData" type="mrm:DataType"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="DataType">
<xsd:sequence>
<xsd:element name="Data" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:element name="HTTPInput" type="mrm:HTTPMessageType"/>
<xsd:element name="HTTPOutput" type="mrm:HTTPMessageType"/>
</xsd:schema>

I use NetTool (v 4.5.1) to put this SOAP message:

Code:

<?xml version='1.0' encoding='UTF-8'?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Body>
<ns1:http xmlns:ns1="tns:HTTPMsgSetPortType" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<HTTPInputBody xmlns:ns2="http://www.mrmnames.net" xsi:type="ns2:HTTPMessageType">
<URL xsi:type="xsd:string">Test_url_ejemplo01</URL>
<InputData xsi:type="ns2:DataType">
<Data xsi:type="xsd:string">TEST_input_ejemplo01</Data>
</InputData>
<OutputData xsi:type="ns2:DataType">
<Data xsi:type="xsd:string">TEST_input_ejemplo01</Data>
</OutputData>
</HTTPInputBody>
</ns1:http>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

And then I invoke the web service so that it returns this soap message:

Code:

<?xml version="1.0"?>
<tns:Envelope xmlns:tns="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:ns2="http://www.mrmnames.net"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<tns:Body>
<NS1:http xmlns:NS1="tns:HTTPMsgSetPortType" tns:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<HTTPInputBody xsi:type="ns2:HTTPMessageType">
<URL xsi:type="xsd:string">Test_url_ejemplo01</URL>
<InputData xsi:type="ns2:DataType">
<Data xsi:type="xsd:string">TEST_input_ejemplo01</Data>
</InputData>
<OutputData xsi:type="ns2:DataType">
<Data xsi:type="xsd:string">xxxNEWDATAxxx</Data>
</OutputData>
</HTTPInputBody>
</NS1:http>
</tns:Body>
</tns:Envelope>

In this response soap message the field OutputData.Data has the new value 'xxxNEWDATAxxx'

But the problem that I have is that I donÂ´t know what happens

When I test this web service with a client application it retuns nothing.
I generate the wsdl files and then wsdl2java (with AXIS) to generate a java client applicacion. My test class is:

Code:

public static void main(String[] args) {
try {
Ej_01HTTP_SOAP_Service service = new Ej_01HTTP_SOAP_ServiceLocator();
Ej_01PortType port = service.getHTTPSOAPPort();

HTTPMessageType msgIn = new HTTPMessageType();
DataType data_in = new DataType();
data_in.setData("TEST_Input_ejemplo01");
msgIn.setURL("Test_url_ejemplo01");
msgIn.setInputData(data_in);

HTTPMessageType msgOut = new HTTPMessageType();
DataType data_out = new DataType();
data_out.setData("TEST_Output_ejemplo01");
msgIn.setOutputData(data_out);

msgOut = port.message_Category(msgIn);

System.out.println("DATA is :" + msgOut.getOutputData().getData());
} catch (Exception ex){
ex.printStackTrace();
}
}

And the result is the same that I put in the InputData.:

â€œDATA is :TEST_Output_ejemplo01â€

Can anyone help me? Why do I get the input data? is there any problem with the response soap message?
I extract this sample from:
http://www-128.ibm.com/developerworks/websphere/library/techarticles/0311_withers/withers.html
Sample 3 Scenario 2 and Websphere Integrator.

Thanks.

Emilio.
