Subject [jira] Commented: (AXIS2-3301) Generated WSDL has validation errors when methods launch exceptions

nadir amra commented on AXIS2-3301:
-----------------------------------

I think this is a major problem so it needs some focus since tools like eclipse indicate that
the generated the WSDL is not valid and affects the generation of client stub code. So here
are the various artifacts to recreate (we are using Axis 1.3):

A POJO, ConvertTemp3Services() is deployed that returns an object of type CONVERTTEMPResult
.  The java classes are very simple: 

===================================
package iseries.wsbeans.converttemp3;

public class ConvertTemp3Services
{
    public ConvertTemp3Services()
    {
        super();
    }

    public CONVERTTEMPResult converttemp()
    {
        CONVERTTEMPResult resultData = new CONVERTTEMPResult();
        resultData.set_TEMPOUT("99");
        return resultData;
    }
}
==============================
package iseries.wsbeans.converttemp3;

import java.io.Serializable;

public class CONVERTTEMPResult implements Serializable
{
    private static final long serialVersionUID = -6046540633483862560L;
    private String TEMPOUT = "";

    public CONVERTTEMPResult()  { super(); }
    public void set_TEMPOUT(String value) { TEMPOUT = value; }
    public String get_TEMPOUT() { return TEMPOUT; }
}
===============================

The services.xml file is as follows:

===============================
<?xml version="1.0" encoding="UTF-8"?>
<service activate="true" name="ConvertTemp3" scope="application">
    <description/>
    <messageReceivers>
        <messageReceiver
            class="org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver" mep="http://www.w3.org/2004/08/wsdl/in-only"/>
        <messageReceiver
            class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" mep="http://www.w3.org/2004/08/wsdl/in-out"/>
    </messageReceivers>
    <parameter name="ServiceClass">iseries.wsbeans.converttemp3.ConvertTemp3Services</parameter>
    <parameter name="useOriginalwsdl">false</parameter>
    <operation name="converttemp"/>
    <excludeOperations/>
</service>
===============================

The Axis 3 automatically generates the following WSDL:

===============================
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

		</wsdl:port>
	</wsdl:service>
</wsdl:definitions>

===========================

The problem is the namespace ns1  in "ns1:CONVERTTEMPResult" in the "converttempResponse"
element. Bascially the WSDL validator in eclipse indicates the following errors:

       IWAB0380E Errors were encountered while validating XML schemas.
       XSD: Type reference 'http://converttemp3.wsbeans.iseries/xsd#CONVERTTEMPResult' is
unresolved

In axis 1.1 (not sure about 1.2), everything use to be in 1 schema.  Not sure why this was
changed.  Please fix or give me some clues on where I should take a look and I can fix.  Thanks.
