GET_SCHEMA_VIEW_VALUES gives output null

Question

Hi,
I am new to UCM. I am using below RIDC code:
dataBinder.putLocal("IdcService", "GET_SCHEMA_VIEW_VALUES");
dataBinder.putLocal ("schViewName", "SecurityGroups");
ServiceResponse response = idcClient.sendRequest (userContext, dataBinder);
DataBinder serverBinder = response.getResponseAsBinder();
DataResultSet resultSet = serverBinder.getResultSet("SecurityGroups");
for (DataObject dataObject : resultSet.getRows ())
          System.out.println (" Security Group : " + dataObject.get ("SecurityGroups") );
i want the list of security group as out put.
But the out put i am getting is as below:
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Security Group : null
Please help me with what is wrong in the code.
Thanks.

You can use the HowToComponents and the available SampleComponents (google searching will bring you to the download pages) to find samples of queries in components. The Developer doc also has sample query components.
you have to use the available methods to find the names of the elements. You already found that the DataResultSet contains DataObjects. You just have to continue to drill down until you find the element (i.e., Field) names. You can quickly use the java debugger to crack open objects and see their contents. That's how to determine in any case, but in this case you knew what schema you were looking into. In that case, you should simply be able to check the schema/view in the config manager applet. Without even looking at the backing table, you can see that the Internal Column is dGroupName and the Visible Column is dDescription.
Hope this helps,
