Oracle MAF WebService invokeDataControlMethod SOAP error - web-services

Question

Any help in resolving this invokeDataControl Method will be greatly appreciated. Please find the link below for a complete reference of the problem. I was basically trying to execute an Oracle/Java MAF example to understand the concept and present it to user for a critical go/no-go situation.
Environment:
1) Jdeveloper 12.1.3.0.0
2) MAF 2.0.1
3) Example tried: DSI037 in https://java.net/projects/smuenchadf/pages/ADFMobile
OR "http://deepakcs.blogspot.com/2013/06/offline-data-synchronization-for-adf.html"
4) MAC OS 10.9
5) WebLogic 12C
6) Error Message
[SEVERE - oracle.adfmf.framework - HttpServiceConnection - log] Connection Error: 500
[SEVERE - oracle.adfmf.framework - HttpTransport - parseResponse] Response [Error: {0}]: {1}
[SEVERE - oracle.adfmf.framework - SoapTransportLayer - invokeSoapRequest] Encountered exception while invoking SOAP request
EndPoint: http://XXX.XXX.XXX.XXX:80/EJBSyncWebServiceApp/SessionFacadeBeanService
SOAPAction: "http://service.soap.dsid.com/persistDepartments"
Exception: HTTP Status Code 500 Internal Server Error: The server encountered an unexpected condition which prevented it from fulfilling the request.
7) More Details:
The following code was executed. The method and all others are working fine in HTTP analyzer or when individually executed (binding "persistDepartments" with a button) but not when wrapper in AdfmfJavaUtilities.invokeDataControlMethod
public void syncDataFromOfflineToOnline() {
Trace.log(Utility.FrameworkLogger, Level.FINE, this.getClass(), "syncDataFromOfflineToOnline",
"Executing syncDataFromOfflineToOnline Method");
try {
Connection conn = DBConnectionFactory.getConnection();
conn.setAutoCommit(false);
PreparedStatement pStmt =
conn.prepareStatement("SELECT DEPARTMENT_ID, DEPARTMENT_NAME, LOCATION_NAME, STATUS from DEPARTMENTS WHERE STATUS IN (?, ?, ?)");
pStmt.setString(1, STATUS_NEWLY_CREATED);
pStmt.setString(2, STATUS_MODIFIED);
pStmt.setString(3, STATUS_DELETED);
ResultSet rs = pStmt.executeQuery();
while (rs.next()) {
List namesList = new ArrayList(1);
List paramsList = new ArrayList(1);
List typesList = new ArrayList(1);
Departments dept = new Departments();
dept.setDepartmentId(rs.getInt("DEPARTMENT_ID"));
dept.setDepartmentName(rs.getString("DEPARTMENT_NAME"));
dept.setLocationName(rs.getString("LOCATION_NAME"));
dept.setStatus(STATUS_NOT_CHANGED);
if (rs.getString("STATUS").equals(STATUS_NEWLY_CREATED)) {
System.out.println("I got a STATUS_NEWLY_CREATED");
GenericType gtDept =
GenericTypeBeanSerializationHelper.toGenericType("MYWS.Types.persistDepartments.arg0",
dept);
namesList.add("arg0");
paramsList.add(gtDept);
typesList.add(Object.class);
AdfmfJavaUtilities.invokeDataControlMethod("MYWS", null, "persistDepartments", namesList,
paramsList, typesList);
//Once the data sync with online, change the status for the row as STATUS_NOT_CHANGED
PreparedStatement pStmt1 =
conn.prepareStatement("UPDATE DEPARTMENTS SET STATUS=? WHERE DEPARTMENT_ID=?");
pStmt1.setString(1, STATUS_NOT_CHANGED);
pStmt1.setInt(2, rs.getInt("DEPARTMENT_ID"));
pStmt1.execute();
conn.commit();

Answer 1

I faced this problem.
Change the typesList.add(Object.class) to typesList.add(GenericType.class)
