We are facing an issue while porting it to Axis2. The class hierarchy looks like: QRequest --> Abstract class Project --> Child class deriving from QRequest with some fields In the web service, I have defined a method String getStringRequest(QRequest obj) Now, from the client side, when I call this method and pass an instance of "Project", it fails. The stack trace mentions "InstantiationExceptionConstructorAccessorImpl". My guess is that axis is trying to instantiate the abstract class here. I am copying SOAP request and response below. Any help would be greatly appreciated. Thanks, Aman SOAP Request ----------------------- <?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema";><soap:Body><getStringReques t xmlns="http://webservice.manager.quark.com";><request xmlns:q1="http://ro.clientsdk.manager.quark.com/xsd"; xsi:type="q1:Project"><q1:request xsi:nil="true" /><q1:jobJacket xsi:nil="true" /><q1:jobTicket xsi:nil="true" /><q1:projectName xsi:nil="true" /><q1:saveAs xsi:nil="true" /><q1:xMLVersion xsi:nil="true" /></request></getStringRequest></soap:Body></soap:Envelope> SOAP Response ------------------------- <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";><soapenv:Body> <soapenv:Fault><faultcode>soapenv:Server</faultcode><faultstring>unknown </faultstring><detail /></soapenv:Fault></soapenv:Body></soapenv:Envelope>
