Xrpcc: Generate stub from WSDL

Question

Hi,
I created a JAX-RPC based web services and used xrpcc tool to generate the server-side classes and wsdl file. And then deployed them on tomcat successfully.
To access the web service, the remote client needs to get the wsdl document (in this case, i used the one generated by the xrpcc tool on the service side) and generate the client-side stub and other classes.
However, i got an error message when trying to generate the stub:
error: modeler error: invalid entity name: "PriceQuote" (in namespace: "http://www.w3.org/2001/XMLSchema")
The wsdl document looks as follows:
<?xml version="1.0" encoding="UTF-8"?>
<definitions name="TestService" targetNamespace="http://www.deitel.com/test.wsdl" xmlns:tns="http://www.deitel.com/test.wsdl" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">
<message name="getPrice">
<part name="String_1" type="xsd:string"/></message>
<message name="getPriceResponse">
<part name="result" type="xsd:PriceQuote"/></message>
<portType name="Test">
<operation name="getPrice">
<input message="tns:getPrice"/>
<output message="tns:getPriceResponse"/></operation></portType>
<binding name="TestBinding" type="tns:Test">
<operation name="getPrice">
<input>
<soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="encoded" namespace="http://www.deitel.com/test.wsdl"/></input>
<output>
<soap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" use="encoded" namespace="http://www.deitel.com/test.wsdl"/></output>
<soap:operation soapAction=""/></operation>
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="rpc"/></binding>
<service name="TestService">
<port name="TestPort" binding="tns:TestBinding">
<soap:address location="http://zhang:8080/jaxrpc-test/test/endpoint/Test"/></port></service></definitions>
I noticed that the error is caused by PriceQuote data type. Then I added PriceQuote data type definition to the wsdl file.
<types>
<xsd:schema
targetNamespace="http://www.deitel.com/schema"
xmlns="http://www.w3.org/2001/XMLSchema">
<xsd:complexType name="PriceQuote">
<xsd:sequence>
<xsd:element name="price" type="xsd:double"/>
<xsd:element name="ISBN" type="xsd:string"/>
<xsd:element name="storeID" type="xsd:int"/>
<xsd:element name="storeDescription" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
</types>
<message name="getPrice">
<part name="String_1" type="xsd:string"/></message>
<message name="getPriceResponse">
<part name="result" type="xsd1:PriceQuote"/></message>
The xrpcc tool then can generate the client-side stub and classes without any problems. However, when the client is executed, I got the following error message:
java.rmi.RemoteException: deserialization error: deserialization error: deserial
ization error: deserialization error: unexpected element type: expected={http://
www.deitel.com/schema}PriceQuote, actual={http://www.w3.org/2001/XMLSchema}Price

Any suggestions?
Thanks in advance,

Hi Todor,
I found out what caused the problem: I used
"http://www.w3.org/2001/XMLSchema" as the
typeNameSpace in the configuration file that is passed
into the xrpcc tool when generates the wsdl document.
Once I changed it to something else, everything works
fine.
Thanks,
Su
