How to return a complex object from an axis web service

Question

Hi all,

I am writing a simple web service to return an object with 2 properties.

I am embedding the service into an existing web application.

My wsdd looks like this.

<globalConfiguration>
    <parameter name="adminPassword" value="admin"/>
    <parameter name="sendXsiTypes" value="true"/>
    <parameter name="sendMultiRefs" value="true"/>
    <parameter name="sendXMLDeclaration" value="true"/>
    <parameter name="axis.sendMinimizedElements" value="true"/>

    <requestFlow>
        <handler type="java:org.apache.axis.handlers.JWSHandler">
            <parameter name="scope" value="session"/>
        </handler>
        <handler type="java:org.apache.axis.handlers.JWSHandler">
            <parameter name="scope" value="request"/>
            <parameter name="extension" value=".jwr"/>
        </handler>
    </requestFlow>
</globalConfiguration>

<handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/>
<handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/>
<handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>

<transport name="http">
    <requestFlow>
        <handler type="URLMapper"/>
        <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>
    </requestFlow>
</transport>


<transport name="local">
    <responseFlow>
        <handler type="LocalResponder"/>
    </responseFlow>
</transport>


<service name="helloService" provider="java:RPC" style="document" use="literal">
    <parameter name="className" value="ws.example.HelloService"/>
    <parameter name="allowedMethods" value="*"/>
    <parameter name="scope" value="application"/>
</service>

I am able to deploy it successfully.

If I try to invoke the method which returns a String, it is successfully returning the String.

But when I invoke the method which returns an object, I am getting the following error.

AxisFault faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException faultSubcode: faultString: org.xml.sax.SAXParseException: Premature end of file. faultActor:

Can any body help?

Hi all,

I sorted this by following information provided at other forums.

We need to use if complex types need to be returned.

Thank you.
