Loosing context setting in AMImpl

Question

Hi,
R12.
I have created a custom OAF page which runs in apps.
When I call pl/sql packages I seem to loose the context setting.
So I tried something and I see a difference in behaviour when:
I do
     - create a method in AMImpl
          This method does the call to the pl/sql (Oracle callable statement)
     - create a method in CO to call method in AMImpl
     - call method in CO from processFormRequest
or I do
     - call pl/sql in processFormRequest (Oracle callable statement)
I loose the context when I call the pl/sql from the AM.
When I call the pl/sql from processFormRequest, the context is not lossed. The pl/sql runs in proper org settings and finds data.
Why is that? Do I need to do something additional to keep that context?
thanks
Ronny

No problem. Here it is:
in PFR
System.out.println("in SettleBatchesCO, processFormRequest, checking for supported actions ");
OAApplicationModule am = pageContext.getApplicationModule(webBean);
// Check for the RebuildBatch button
if (pageContext.getParameter("RebuildBatch") != null)
System.out.println("in SettleBatchesCO, processFormRequest, RebuildBatch : before rebuilding batch");
rebuildBatch(pageContext, webBean);
System.out.println("in SettleBatchesCO, processFormRequest, RebuildBatch : after rebuilding batch");
In CO
public void rebuildBatch(OAPageContext pageContext, OAWebBean webBean)
String currBatchId = pageContext.getParameter("SearchBatchId");
System.out.println("in SettleBatchesCO, rebuildBatch : currBatchId : " + currBatchId);
if (currBatchId == null || ("".equals(currBatchId.trim())))
throw new OAException("XXFSS", "XXFSS_SETTLE_NO_BATCH");
// Process the modified transaction data
OAApplicationModule am = pageContext.getApplicationModule(webBean);
Serializable[] parameters = { currBatchId
HashMap resultRebuildBatchMap = (HashMap)am.invokeMethod("rebuildThisBatch", parameters);
String rebuildStatus = (String)resultRebuildBatchMap.get("RebuildStatus");
String rowCount = (String)resultRebuildBatchMap.get("RowCount");
System.out.println("SettleBatchesCO, rebuildBatch, rebuildStatus : " + rebuildStatus);
System.out.println("SettleBatchesCO, rebuildBatch, rowCount : " + rowCount);
// Set the status of the batch back to SELECTED
Serializable[] statusParameters = { currBatchId
, "SELECTED"
HashMap resultStatusBatchMap = (HashMap)am.invokeMethod("setStatusOfThisBatch", statusParameters);
String resultSetStatus = (String)resultStatusBatchMap.get("SetStatusStatus");
String processedStatusRows = (String)resultStatusBatchMap.get("RowCount");
System.out.println("SettleBatchesCO, rebuildBatch, resultSetStatus : " + resultSetStatus);
System.out.println("SettleBatchesCO, rebuildBatch, processedStatusRows : " + processedStatusRows);
} // rebuildBatch
In AM
/**Se the status of the batch by calling the stored package procedure for it
public HashMap setStatusOfThisBatch( String BatchId
, String StatusCode
throws SQLException
HashMap setstatusBatchHash = new HashMap(2);
System.out.println("settleARbatchesAMImpl, setStatusOfThisBatch : setStatusOfThisBatch (+) ");
OracleCallableStatement callPLSQLStmt = null;
try {
// Put your PL/SQL block in a String variable.
String plsqlStmt = "begin xxfss_ar_stlmnt.p_update_status \n" +
" ( :1 \n" +
" , :2 \n" +
" , :3 \n" +

OADBTransaction txn = getOADBTransaction();
// Pass the PL/SQL block to the callable Statement
callPLSQLStmt = (OracleCallableStatement)txn.createCallableStatement(plsqlStmt, 1);
// Fill the input parameters
callPLSQLStmt.setString(1, BatchId);
callPLSQLStmt.setString(2, StatusCode);
// And register the output parameter types
callPLSQLStmt.registerOutParameter(3, Types.VARCHAR);
callPLSQLStmt.executeUpdate();
// After execute you can get the value of pl/sql block output
String RowCount = callPLSQLStmt.getString(3);
callPLSQLStmt.close();
System.out.println("settleARbatchesAMImpl, setStatusOfThisBatch : after call to update ");
setstatusBatchHash.put("SetStatusStatus", "SUCCESS");
setstatusBatchHash.put("RowCount", RowCount);
} catch(SQLException sqle) {
String errorMessage = sqle.getMessage();
callPLSQLStmt.close();
setstatusBatchHash.put("SetStatusStatus", "FAIL");
setstatusBatchHash.put("RowCount", -1);
throw new OAException("Setting the status of this batch has failed: " + errorMessage );
System.out.println("settleARbatchesAMImpl, setStatusOfThisBatch : setStatusOfThisBatch (-) ");
return setstatusBatchHash;
} // end setStatusOfThisBatch
/**Do the rebuilding of the batch by calling the stored package procedure for it
