Add code to a button?

Question

Hi friends,
[Apps R12]
If I add a button to an OAF screen :
I have no idea of how :
- to add code when it's clicked... The idea would be to call a database procedure that receives,as parameters, certain values of that OAF screen and that returns, in an output parameter, a value to be posted in a screen field.
Any example would be appreciated
Thanks!
Jose L.

package oracle.apps.fnd.framework.toolbox.labsolutions.webui;
import oracle.apps.fnd.common.VersionInfo;
import oracle.apps.fnd.framework.webui.OAControllerImpl;
import oracle.apps.fnd.framework.webui.OAPageContext;
import oracle.apps.fnd.framework.webui.beans.OAWebBean;
import oracle.apps.fnd.framework.webui.beans.OABodyBean;
import oracle.apps.fnd.framework.webui.beans.layout.OAPageLayoutBean;
import oracle.apps.fnd.framework.server.OADBTransaction;
import oracle.apps.fnd.framework.OAApplicationModule;
import java.sql.CallableStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import oracle.apps.fnd.framework.webui.beans.message.OAMessageLovInputBean;
import java.util.Enumeration;
import oracle.apps.fnd.framework.webui.beans.message.OAMessageTextInputBean;
import oracle.apps.fnd.framework.webui.OAWebBeanConstants;
* Controller for ...
public class EmpSearchPGLayOutRNCO extends OAControllerImpl

VersionInfo.recordClassVersion(RCS_ID, "%packagename%");
* Layout and page setup logic for a region.

if (pageContext.getParameter("clearclearButton")!=null)
OADBTransaction txn = getDBTransaction();
CallableStatement cs =
txn.createCallableStatement("begin dbms_application_info.set_module(:1, :2);
end;");
try{
cs.setString(1, module);
cs.setString(2, action);
cs.execute();
cs.close();
catch (SQLException e)
try { cs.close } catch (Exception(e) {}
throw OAException.wrapperException(sqle); }
}
