While it is possible to use "/ddm.ddmforminstancerecord/get-form-instance-records" public API (jsonws) to retrieve form entries data, there is no public API for retrieving its field values.However, there is available "getDDMFormInstances" method, which can be used to accomplish that in plain regular java.
Here's a quick example on how to use it:
import com.liferay.dynamic.data.mapping.service.DDMFormInstanceLocalServiceUtil;
import com.liferay.dynamic.data.mapping.model.DDMFormInstance;
import com.liferay.dynamic.data.mapping.model.DDMFormInstanceRecord;
import com.liferay.dynamic.data.mapping.storage.DDMFormValues;
import com.liferay.dynamic.data.mapping.storage.DDMFormFieldValue;
import com.liferay.portal.kernel.exception.PortalException;
import com.liferay.dynamic.data.mapping.model.Value;
List<DDMFormInstance> ddmFmInstanceList = DDMFormInstanceLocalServiceUtil.getDDMFormInstances(-1, -1);
for(DDMFormInstance ddmFmInstance : ddmFmInstanceList) {
List<DDMFormInstanceRecord> reclist = ddmFmInstance.getFormInstanceRecords();
for(DDMFormInstanceRecord rec : reclist) {
DDMFormValues fmvals;
try {
fmvals = rec.getDDMFormValues();
List<DDMFormFieldValue> formFieldVals = fmvals.getDDMFormFieldValues();
for (DDMFormFieldValue fmval : formFieldVals) {
Value val = fmval.getValue();
String data = val.getString(Locale.ROOT);
String name = fmval.getName();
out.println(" My DDM Form Values Details : "+name+" => "+data); } }
catch (PortalException e) { e.printStackTrace(); } } }
Executing this script from "Control Panel > Server Administration > Script" will list all the form's field values.
