∟org.apache.axis2.rpc.client.RPCServiceClient Class

This section describes the org.apache.axis2.rpc.client.RPCServiceClient class that represents an RPC based Web service client. The invokeBlocking() method can be used to invoke an RPC method based operation without using OMElement objects.

To make invoking an RPC method based Web service easier, Axis2 extends the org.apache.axis2.client.ServiceClient class to a sub class, org.apache.axis2.rpc.client.RPCServiceClient, to offer additional methods for client programming.

1. Creating an RPC method based service client object from an existing WSDL document with this constructor method:

   RPCServiceClient client =
      new RPCServiceClient(null, wsdlURL, serviceQName, portName)
// "null" indicates a default ConfigurationContext object to be used
// "wsdlURL" specifies a WSDL document using a new URL(wsdlUrlString)
// "serviceQName" specifies a service within the WSDL document
//    using a new QName(tns,serviceName)
//    "tns" specifies the target namespace of the Web service
// "portName" specifies a port within the service using the port name

2. Invoking an RPC method based operation and receiving return values as an OMElement with this invokeBlocking() method:

   response = invokeBlocking(operationQName, args)
// "operationQName" specifies an operation within the service
//    using a new QName(tns,operationName)
//    "tns" specifies the target namespace of the Web service
// "args" specifies input parameters as an Object[].
// "response" receives the SOAP Body element in the response message
//    as an org.apache.axiom.om.OMElement object

3. Invoking an RPC method based operation and receiving return values as an Object[] with this invokeBlocking() method:

   returnValues = invokeBlocking(operationQName, args)
// "operationQName" specifies an operation within the service
//    using a new QName(tns,operationName)
//    "tns" specifies the target namespace of the Web service
// "args" specifies input parameters as an Object[].
// "returnValues" receives return values as an Object[].
