Code generation from WSDL causes exception

Question

I'm using Axis2 1.5.1 (wsdl2java) for code generation (client stubs) from a given WSDL file.
The webservice is provided by an external application.

<?xml version="1.0" encoding="utf-8"?>  
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"  
xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility- 1.0.xsd"

<wsdl:types>  
<xsd:schema targetNamespace="http://tempuri.org/Imports">

<xsd:include schemaLocation="SampleApp.App.ApplicationManager.RemoteApplication3.xsd" />  
</xsd:schema>  
</wsdl:types>  
...  
</wsdl:definition>  

Content of RemoteApplication0.xsd is as follows:

<?xml version="1.0" encoding="utf-8"?>  
<xs:schema xmlns:tns="http://schemas.microsoft.com/Message" 
elementFormDefault="qualified"  
targetNamespace="http://schemas.microsoft.com/Message"

<xs:complexType name="MessageBody">  
<xs:sequence>  
<xs:any minOccurs="0" maxOccurs="unbounded" namespace="##any" />  
</xs:sequence>  
</xs:complexType>  
</xs:schema>  

commandline:

wsdl2java -ss -g -d adb -or -p com.sampleapp.ws.generated.client -uri SampleRemoteProcess.wsdl  

Generation process causes an exception.

Seems there is a namespace problem, but i dont know how to fix it.
Can anybody give me a hint!

Answer 1

the problem is your use of "include". "include"ed schemas must have the same target namespace as the schema in which the include resides (you are esentially splitting the same namespace across multiple files). you must "import" a schema to use another schema file with a different target namespace.
