Issue in Calling PL/SQL packages using callable statement

Question

Hi ,
I have the requirement of calling two pl/sql packages , After call of first package is successful , i need to pass the output of that first package as input to second package.
Since i have called both the packages in same method of AM, first package gets executed successfully but second package doesnt get the input values required from first package and results in error.
Looks like since commit is happening in the single session second package is passed with NULL values.
Need suggestion for proper way of calling pl/sql packages when second package is dependant on first one:
Code used inside AM Method:
if("PENDING_XXX".equals(regVORow.getRegStatus()))
regVORow.setRegStatus("VENDOR_CREATED");
getOADBTransaction().commit();
OracleCallableStatement cStmt = null;
OADBTransaction dbTxn = getOADBTransaction();
NUMBER vendor_id = new NUMBER(-1);
NUMBER vendor_site_id = new NUMBER(-1);
int vendor_id_value = -2000;
String vendor_number = null;
try
cStmt = (OracleCallableStatement)dbTxn.createCallableStatement("begin *XXB_POS_PVT.create_vendo*r( p_vendor_name => :1, p_supplier_reg_id => :2, p_vendor_id=>:3); end;", 1);
cStmt.setString(1, regVORow.getSupplierName());
cStmt.setNUMBER(2, new Number(Integer.parseInt(supplierId)));
cStmt.registerOutParameter(3, 4);
cStmt.execute();
vendor_id = cStmt.getNUMBER(3);
vendor_id_value = vendor_id.intValue();
catch(SQLException e)
throw new OAException(e.getMessage());
Number vendorId = new Number(vendor_id_value);
regVORow.setVendorId(vendorId);
if(vendorId != null)
vendor_number = getSupplierVendorNumber(vendorId);
getOADBTransaction().commit();
AsiPosSupplierOpCosVOImpl regOpCosVO = (AsiPosSupplierOpCosVOImpl)this.getAsiPosSupplierOpCosVO1();
AsiPosSupplierOpCosVORowImpl row = null;
int fetchedRowCount = regOpCosVO.getFetchedRowCount();
RowSetIterator createIter1 = regOpCosVO.createRowSetIterator("createIter1");
if(fetchedRowCount > 0)
createIter1.setRangeStart(0);
createIter1.setRangeSize(fetchedRowCount);
for(int i = 0; i < fetchedRowCount; i++)
row = (AsiPosSupplierOpCosVORowImpl)createIter1.getRowAtRangeIndex(i);
if(row.getApprovalStatus().equalsIgnoreCase("HEAD_APPROVED"))
try
oadbtransactionimpl.writeDiagnostics(this,"Creating Site - " + vendor_id_value+" "+row.getSupplierOpcoCode()+" "+supplierId,1);
cStmt = (OracleCallableStatement)dbTxn.createCallableStatement("begin *XXB_POS_PVT.create_vendor_sites*(p_supplier_reg_id => :1, p_vendor_id=>:2, p_opco_code=>:3, p_vendor_site_id=>:4); end;", 1);
cStmt.setNUMBER(1, new Number(Integer.parseInt(supplierId)));
cStmt.setNUMBER(2, new Number(vendor_id_value));
cStmt.setString(3,row.getSupplierOpcoCode());
cStmt.registerOutParameter(4, 4);
cStmt.execute();
vendor_site_id = cStmt.getNUMBER(4);
getOADBTransaction().commit();                                    
catch(SQLException e)
throw new OAException(e.getMessage());
createIter1.closeRowSetIterator();

Hi ,
There are some validation that can be performed from Entity level ( EO ) , you can go through them in Jdev guide .
It depends on the business requirement , not all validation can be performed from Entity level .
Let us know your business requirement , will try to clear your doubt .
