Import metadata error.

Question

Hi, everyone.
I have a task.
I need to develop ADF Business Component using only WEB-services and integrate this app into BI Repository.
So, I developed this app, and completed all steps here -> [http://docs.oracle.com/cd/E15586_01/fusionapps.1111/e20836/adf.htm#CHDDAFAG] .
Metadata was imported but when I try to view data this exception appears:
"An error occurs while calling remote service ADFService11G"
In details it can't query data from table, because table doesn't exist.
In ADF BC: I've created a programmatic view object. Here it's listing:
package sit.model;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;
import oracle.jbo.server.ViewObjectImpl;
import oracle.jbo.server.ViewRowImpl;
import oracle.jbo.server.ViewRowSetImpl;
import sit.tsds.TSServiceViewObjectImpl;
import ts.service.stub.FilterBean;
import ts.service.stub.TaskBean;
public class v_baseTaskImpl extends TSServiceViewObjectImpl {
* This is the default constructor (do not remove).
public v_baseTaskImpl(){
super();
public v_baseTaskImpl(String newFilterName){
this.filterName = newFilterName;
private String filterName = "Все задачи";
protected String rootTaskNumber = "1";
protected void executeQueryForCollection(Object qc, Object[] params, int noUserParams) {
super.executeQueryForCollection(qc, params, noUserParams);
* hasNextForCollection - overridden for custom java data source support.
protected boolean hasNextForCollection(Object qc) {
boolean bRet = super.hasNextForCollection(qc);
return bRet;
* createRowFromResultSet - overridden for custom java data source support.
protected v_baseTaskRowImpl createRowFromResultSet(Object qc, ResultSet resultSet) {
v_baseTaskRowImpl btr = (v_baseTaskRowImpl)super.createRowFromResultSet(qc, resultSet);
Long a = 12321L;
populateAttributeForRow(btr,0,"1");
populateAttributeForRow(btr,1,"shortName");
populateAttributeForRow(btr,2,"name");
populateAttributeForRow(btr,3,a);
populateAttributeForRow(btr,4,a);
populateAttributeForRow(btr,5,a);
populateAttributeForRow(btr,6,"Desc");
populateAttributeForRow(btr,7,a);
populateAttributeForRow(btr,8,a);
populateAttributeForRow(btr,9,a);
populateAttributeForRow(btr,10,"categ");
populateAttributeForRow(btr,11,"stat");
populateAttributeForRow(btr,12,"resol");
populateAttributeForRow(btr,13,"prior");
populateAttributeForRow(btr,14,"subm");
populateAttributeForRow(btr,15,"handl");
populateAttributeForRow(btr,16,"2");
populateAttributeForRow(btr,17,"00001");
return btr;
* getQueryHitCount - overridden for custom java data source support.
public long getQueryHitCount(ViewRowSetImpl viewRowSet) {
long value = super.getQueryHitCount(viewRowSet);
return value;

in v_baseTaskImpl I've just tried to put some test values.
So, there is my question:
Is problem with ADF BC or in BI? And was file v_baseTaskImpl edited correctly? If no, please, give me some advice about creating programmatic view objects.
I'll be very grateful for any answers.
thanks, and best regards, Eugene.

Answer 1

Hi,
I registered the location in control center, but I yet can not import the metadata. Once I try to import the metadata with Import Metadata Wizard, "import service failed" error poped up.
I have no idea.
Just following the normal steps: 1. Create a module and identify the type as source.
2. During the process of creating the module, should enable a location relate to this module.
3. Make sure the location works well with the corrected database connection.
4. Certainly, should register the location through control center.
Hari, do I get the right steps? Any problem please let me know.
Thanks a lot.
