if("update".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
String rowReference = pageContext.getParameter(OAWebBeanConstants.EVENT_SOURCE_ROW_REFERENCE);
String userName="";
if(rowReference != null)
PosUserAdminVORowImpl vorowimpl = (PosUserAdminVORowImpl)am.findRowByRef(rowReference);
userName = vorowimpl.getUserName();
System.out.println("print username"+userName);
OADBTransaction txn =am.getOADBTransaction();
CallableStatement callablestatement1 = txn.createCallableStatement("begin FND_USER_PKG.DISABLEUSER(?);end;",1);
System.out.println("procedure1 is:"+callablestatement1);
try
callablestatement1.setString(1,userName);
callablestatement1.executeUpdate();
callablestatement1.close();
txn.commit();
