How to fetch parent form Data in OIM?

public static Map<String, String> getParentFormData(long processKey)

throws tcAPIException, tcInvalidLookupException, tcColumnNotFoundException, tcFormNotFoundException,

tcProcessNotFoundException, tcVersionNotFoundException, tcNotAtomicProcessException, LoginException {

String methodName = "getParentFormData";

System.out.println(CLASS_NAME + "/" + methodName + "; processKey = " + processKey);

tcFormInstanceOperationsIntf formInstOps = Platform.getService(tcFormInstanceOperationsIntf.class);

tcFormDefinitionOperationsIntf formDefOps = Platform.getService(tcFormDefinitionOperationsIntf.class);

tcResultSet tcresultset = formInstOps.getProcessFormData(processKey);

long l1 = formInstOps.getProcessFormDefinitionKey(processKey);

tcResultSet formFieldresultset = formDefOps.getFormFields(l1, formInstOps.getProcessFormVersion(processKey));

int formfieldCount = formFieldresultset.getRowCount();

Map<String, String> result = new HashMap<String, String>();

for (int j1 = 0; j1 < formfieldCount; j1++) {

formFieldresultset.goToRow(j1);

String s4 = formFieldresultset.getStringValue(Structure Utility.Additional Columns.Field Label);

String val = tcresultset

.getStringValue(formFieldresultset.getStringValue(Structure Utility.Additional Columns.Name));

result.put(s4, val);

}

System.out.println("Exiting from the method : " + methodName);

return result;

}
