DATASET-HANDLE (dynamic ProDataSet) parameters

In Java, the client interface for a DATASET-HANDLE parameter is based on the following:

For every Web service object containing a method that passes a DATASET-HANDLE parameter, the WSDL contains a <DatasetHandleParam> element defined as a <complexType> definition. Therefore, a DatasetHandleParam class is created for every client object which contains a method that passes a DATSET-HANDLE parameter.

For input DATASET-HANDLE parameters, the client must create a DatasetHandleParam object, consisting of a MessageElement array containing the XML Schema and data for the DATASET-HANDLE. For output DATASET-HANDLE parameters, the client must parse the XML Schema and data in the MessageElement array.

The following code snippet reads an OUTPUT DATASET-HANDLE from a Web service, outDynDS:

Table 57. Reading OUTPUT DATASET-HANDLE in Java
StringHolder retval = new StringHolder(); DataSetHandleParamHolder dsParamH = new DataSetHandleParamHolder(); // call outDyn.p on appserver appobj.outDyn(retval, dsParamH); DataSetHandleParam dsParam = dsParamH.value; MessageElement domElem[] = new MessageElement[2]; domElem = dsParam.get_any(); // Extract the schema, followed by the data. MessageElement schemaElem = domElem[0]; // parse the XML Schema for the Dataset MessageElement dataElem = domElem[1]; // parse the XML Data for the Dataset
