Problem with Java Client

[janki rathod]

I am trying to invoke a web-service that returns a String to my Java Client..
Here's the code snippet..

String endpoint = "http://203.94.240.89/webservices1.5/services/IRCTCAuthenticationService";

org.apache.axis.client.Call _call = createCall();
_call.setOperation(_operations[0]);
_call.setUseSOAPAction(true);
_call.setSOAPActionURI("");
_call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);
_call.setOperationName(new javax.xml.namespace.QName("http://webservices.irctc.com", "endUserAuthentication"));

setRequestHeaders(_call);
setAttachments(_call);
java.lang.Object _resp = _call.invoke(new java.lang.Object[] {inputXML});

This throws an error from _call.invoke, which is
AxisFault

Here is a little sample:
========================

 
try
{
Call call = (Call) new Service().createCall();
call.setOperationName(new QName("urn:xmethods-BNPriceCheck","getPrice"));
call.setTargetEndpointAddress(new java.net.URL("http://services.xmethods.com:80/soap/servlet/rpcrouter"));
call.addParameter("testParam",org.apache.axis.Constants.XSD_STRING,javax.xml.rpc.ParameterMode.IN);
call.setReturnType(org.apache.axis.Constants.XSD_FLOAT);
//call.setr

//String ret = (String) call.invoke( new Object[] { isbn } );

Float f1 = (Float) call.invoke( new Object[] { "0596000685" } );
ret = f1.toString();
        System.out.println("Response Value: " + ret);

}
catch(Exception e)
{
e.printStackTrace();
}


}
