DII client question

[acxjbertr]

I am attempting to write a stand-alone JUnit test to invoke and validate a web service I have running in JBoss 4.0.4GA (JDK 5). According to http://labs.jboss.com/portal/jbossws/user-guide/en/html/clients.html all I need to do is use this:

public void testEchoString() throws Exception
 {
 ServiceFactoryImpl factory = new ServiceFactoryImpl();
 Service service = factory.createService(new QName("ANY_SERVICE_NAME"));

 Call call = service.createCall();
 call.setOperationName(new QName(TARGET_NAMESPACE, "echoString"));
 call.addParameter("String_1", Constants.TYPE_LITERAL_STRING, ParameterMode.IN);
 call.addParameter("String_2", Constants.TYPE_LITERAL_STRING, ParameterMode.IN);
 call.setReturnType(Constants.TYPE_LITERAL_STRING);

 call.setTargetEndpointAddress(TARGET_ENDPOINT_ADDRESS);

 String hello = "Hello";
 String world = "world!";
 Object retObj = call.invoke(new Object[]{hello, world});
 assertEquals(hello + world, retObj);
 }

However, the "echoString" service takes simple String objects as input and my service takes a custom object. I have tried modifying the code to use my object but I am getting an exception. Here is my code:

public void testEchoString() throws Exception {
 ServiceFactoryImpl factory = new ServiceFactoryImpl();
 Service service = factory.createService(new QName("JBossTest2"));

 Call call = service.createCall();
 call.setOperationName(new QName("http://us.mycompany.com/jbosstest2/1.0", "prescreen"));
 call.addParameter("JBossTest2Request", new QName("JBossTest2Request"), ParameterMode.IN);
 call.setReturnType(new QName("com.mycompany.us.test.JBossTest2Reply"));

 call.setTargetEndpointAddress("http://jbertr1005:8080/jbosstest2/1.0");

 String hello = "Hello";
 String world = "world!";
 Object retObj = call.invoke(new Object[] { new JBossTest2Request() });
 assertEquals(hello + world, retObj);
 }

And here is the exception I am receiving:

How do I get a simple DII client to invoke a web service that uses custom objects for input and output?

[thomas.diesler]

The user guide has been updated on this

http://labs.jboss.com/portal/jbossws/user-guide/en/html/clients.html

This type of "do it all yourself" DII is the worst possible choice. Use wsdl + jaxrpc-mapping.xml to configure your client proxy

[sverker]

Thomas,
if the neither wsdl nor jaxrpc-mapping.xml are availible then there are no other option than to use DII. It sucks but that's the case sometimes..

However, I still can't find from the users guide how to do when the web service return a complex type.

My code now looks like this:

 String endpoint = "https://cbg.tele2.com:443/xmlrpc-login";

 ServiceFactory factory = ServiceFactory.newInstance();
 Service service = factory.createService(new QName("ANY_SERVICE_NAME"));
 Call call = service.createCall();
 call.setTargetEndpointAddress(endpoint);
 call.setOperationName(new QName("http://testuri.org", "TRANSLATEIP"));
 call.addParameter("login.user", Constants.TYPE_LITERAL_STRING, ParameterMode.IN);
 call.addParameter("login.password", Constants.TYPE_LITERAL_STRING, ParameterMode.IN);
 call.addParameter("OriginatingCustomerIP", Constants.TYPE_LITERAL_STRING, ParameterMode.IN);

 QName qn = new QName( "item" );
 call.setReturnType(qn,Item.class);
 Item ret = (Item) call.invoke( new Object[] { user, password, ip});

This cause a stack trace like this:
java.lang.IllegalArgumentException: Invalid namespace for type: item
at org.jboss.ws.jaxrpc.SchemaGenerator.assertXmlType(SchemaGenerator.java:104)
at org.jboss.ws.jaxrpc.SchemaGenerator.generateXSDSchema(SchemaGenerator.java:55)

From the doc of this api:

An example request:

<?xml version="1.0" encoding="ISO-8859-1"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:si="http://soapinterop.org/xsd">
<SOAP-ENV:Body>
<ns1:TRANSLATEIP xmlns:ns1="http://testuri.org">
<login.user xsi:type="xsd:string">K123456</login.user>
<login.password xsi:type="xsd:string">XXXXX</login.password>
<OriginatingCustomerIP xsi:type="xsd:string">129.23.23.2</OriginatingCustomerIP>
</ns1:TRANSLATEIP>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

An example response looks the following way:

<?xml version="1.0"?>
<SOAP-ENV:Envelope
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/1999/XMLSchema"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:si="http://soapinterop.org/xsd" xmlns:ns6="http://testuri.org" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<Response>
<item>
<OriginatingCustomerId xsi:type="xsd:string">46736123123</OriginatingCustomerId>
</item>
</Response>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

I was able to implement this with Axis by doing like this:

 QName qn = new QName( XMLConstants.NULL_NS_URI, "item" );
 call.registerTypeMapping(Item.class, qn,
 new org.apache.axis.encoding.ser.BeanSerializerFactory(Item.class, qn),
 new org.apache.axis.encoding.ser.BeanDeserializerFactory(Item.class, qn));
 call.setReturnType(qn);

plus that the Item class contains a type description like this:

 // Type metadata
 private static TypeDesc typeDesc = new TypeDesc(Item.class, true);

 static {
 typeDesc.setXmlType(new QName(XMLConstants.NULL_NS_URI, "item"));
 ElementDesc elemField = new ElementDesc();
 elemField.setFieldName("error");
 elemField.setXmlName(new javax.xml.namespace.QName("", "Error"));
 elemField.setXmlType(new javax.xml.namespace.QName("http://schemas.xmlsoap.org/soap/encoding/", "string"));
 elemField.setNillable(true);

 typeDesc.addFieldDesc(elemField);
 elemField = new org.apache.axis.description.ElementDesc();
 elemField.setFieldName("originatingCustomerId");
 elemField.setXmlName(new javax.xml.namespace.QName("", "OriginatingCustomerId"));
 elemField.setXmlType(new javax.xml.namespace.QName("http://schemas.xmlsoap.org/soap/encoding/", "string"));
 elemField.setNillable(true);
 typeDesc.addFieldDesc(elemField);

 elemField = new org.apache.axis.description.ElementDesc();
 elemField.setFieldName("transactionId");
 elemField.setXmlName(new javax.xml.namespace.QName("", "TransactionId"));
 elemField.setXmlType(new javax.xml.namespace.QName("http://schemas.xmlsoap.org/soap/encoding/", "string"));
 elemField.setNillable(true);
 typeDesc.addFieldDesc(elemField);

 elemField = new org.apache.axis.description.ElementDesc();
 elemField.setFieldName("status");
 elemField.setXmlName(new javax.xml.namespace.QName("", "Status"));
 elemField.setXmlType(new javax.xml.namespace.QName("http://schemas.xmlsoap.org/soap/encoding/", "int"));
 elemField.setNillable(true);
 typeDesc.addFieldDesc(elemField);
 }

How to accomplish the same with jbossws?

The example soap request didn't show correctly. New try:

QName qn = new QName( "item" );

I don't get why you want to make "item" a QName, it's just a simple tag...
So, I suggest something like:

call.addParameter("item", XMLType.XSD_STRING, ParameterMode.IN);
(ofcourse you have to change the parameters)

Success,

Hi Mylene
that was how I interpertated the javadoc for javax.xml.rpc.Call as the purpose is to set the type of the response to a Item object. Isn't what you suggest what I should do if I wanted to have item as a call parameter? I'll try it anyway and see what happens..

[mylene]

Have a look at http://users.skynet.be/pascalbotte/rcx-ws-doc/dii.htm
He gives nice (working) examples, though not JBoss WS specific.

Mylène

[sverker]

Unforturnatly that example still needs the wsdl when the service return an object..

This example shows how to do it on Weblogic:
http://www.manojc.com/?sample25

and earlier in the thread is an example on how to do it wil Axis. However, I can't find a way to do it with JBossWS :(
