UIX BC4J Java

Question

How could I transfer the information from UIX site in my Java class and work it on.
My Scenario:
Each employee works in a departmebt.
Now I want to change the department of a employee.
I show all departments,that I have and I select the current one,
I would like to select another department and display it by my employee.
I call method of my class TestSel in UIX in handlers::
<event name="find" >
<bc4j:findRootAppModule name="ViewAppModule" >
<bc4j:findViewObject name="View" >
<ctrl:method class="bo.TestSel" method="doSel"/>
</bc4j:findViewObject>
</bc4j:findRootAppModule>
</event>
package bo;
import...
public class TestSel {   
public static EventResult doSel(BajaContext bc, Page page, PageEvent event){   
ViewObject res = (ViewObject)bc.getProperty("http://xmlns.oracle.com/uix/bc4j", "viewObject");
Row cur=res.getCurrentRow();
//Not the selected position, but the last of the site (in range)
System.out.println("cur"+cur.getAttribute("Id1").toString()) ;
System.out.println("cur"+cur.getAttribute("FmlyNam").toString()) ;
if (res.getEstimatedRowCount() != 0)
RowSetIterator secondRSI = res.createRowSetIterator("secondRSI");
if (secondRSI.hasNext())
Row firstRow = secondRSI.first(); //the first row
System.out.println(firstRow.getAttribute("Id1").toString()) ;
System.out.println(firstRow.getAttribute("FmlyNam").toString()) ;
secondRSI.closeRowSetIterator();
How could I get selected data record here?
How could I change a value of attributes and apply it in UIX ?
Help me please!!!

Answer 1

Would it be easier to use a custom method on the bc4j Application module?
Take this scenario...
1. User opens UIX XML web page which opens a bc4j App Module..it has a VO based on all employees.
2. User presses the add button and a new employee is created (using the bc4j App Module).
(Notice: no commit yet!)
3. User presses the submit button...fires event REVIEW_SALARY.
4. This event is 'handled' in the event section of the UML XML...it calls:-
public static EventResult handleREVIEW_SALARYEvent (BajaContext context, Page page, PageEvent event)...
5. I now want to call a java class I wrote that computes an employees new salary and updates the employee record with this new salary. This update will fail unless it is part of the same transaction as the one used by the bc4j App Module (that inserted the new employee).
How best to proceed from here?
How about having a method on the bc4j App Mod's VO called 'reviewSalary'? Calling this would use the same transaction? I could then call my java class from within the VO's method? However do I still have the same problem in that my java class expects to be passed the connection object?
The approach you suggested previously seems a touch dangerous....in that these are not 'publically exposed'...and a new release of JDev may break my code.
Thanks,
