Urgent Help Please..How to show an alert in jsp if servlet has an exception

Hi
I am calling a servlet from popup jsp.
When the values are submitted from the jsp I am calling the servlet where i have functionality to send an email. But if email fails in the servlet I have to return to the popupjsp and show an alert to the user.
If any body knows please help.
thanks in advance.

Hi,
Do like this :
In the servlet's doPost() method, add codes in the manner
mentioned below.
public void doPost(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{
PrintWriter out = response.getWriter();
try{
//throw new Exception();
catch(Exception ex){
out.println("<html><body>");
out.println("<script language='javaScript'>");
out.println("alert('Exception Occured Servlet...');</script>");
out.println("</body></html>");
Hope it helps.
Regards,
Sudhir

Load XML in intranet ? urgent help please...

Dear friends, I need urgent help: I have a CAYIN screen (which lets me display evetns, etc) and gives me the option of loading/displaying a FLASH (SWF) file, well, I need this SWF to load some XML data ("texto.xml") but seems that when the CAYIN program which executes flash, does not allow the SWF to find the XML in the same folder...
Then I tried many ways to load the XML file with no success till now. Some tries are :
obj_xml.load("\\192.168.0.100\media\texto.xml")
obj_xml.load("\media\texto.xml")
obj_xml.load("texto.xml")
obj_xml.load("../media/texto.xml")
obj_xml.load("\\media\texto.xml")
obj_xml.load("file:\\192.168.0.100\media\texto.xml")
obj_xml.load("..\\192.168.0.100\media\texto.xml")
I guess I am writting something wrong or forgetting something. Would anyone please help me ? because these files are in an internal server "192.168.0.100" (intranet).
Urgent help please, thanks in advance,

if the swf is in a directory with subdirectory media which contains texto.xml, use:
obj_xml.load("media/texto.xml")

URGENT HELP PLEASE - drop index hangs on SAP

Hi all,
OS = Linux
DBVersion = Oracle10.2.0.2
Need some urgent help advise please on how to get around this problem.
On a SAP system, am trying to drop six indexes, largest is 300MB and smallest is 50MB.
I tried running drop index sapusername.index_name on the 50MB index via SQL*Plus and it seems to be taking forever. Can anyone please suggest if there is anything I can check on the database on why it is taking such a long time?
I can leave it to run overnight but worried that when I come back the next day, it will still be hanged. Is there any quick way of dropping the index, .i.e. drop immediate ... :-)
Am not using SAP's BRTOOLs as it is also hanging from there and the SAP-ADMIN had approved for the DBA to drop it from our end instead.
Any response and advise on this will be very much appreciated.
From Google'ing, I found some that mentioned that the fault could be because of the existence of the constraints on the table that I am dropping the index of.
Checking the table, it has 17 SYS_ named constraints. None of these constraints have INDEX_NAME that refers to the indexes that am dropping.
Should I disable the constraints and then run the drop index again?
Thanks in advance.
Edited by: user649596 on Apr 13, 2010 11:49 PM

Should I disable the constraints and then run the drop index again?NO, certainly not !!
Ask SAP Support on what methods you should use to diagnose the "hang" and what your next step(s) should be.

Storing rows returned back in Memory.Urgent Help please

I have a method is thats all information from the Database and I need to hold this data
in a HashMap of some sort of data structure
Lets suppose this result set returns 5 rows.I need to hold all 5 rows in a datastructure.
The variable f_OrderID is the principal and this should return back all values associated with it.
I cant use HashMap as the key:f_OrderID is always the same,
Key f_orderID
Value :f_EffTs,f_ClrAcct f_MsgSeqNum
Please can anyone help me how to store this in memory,
using the same f_OrderID but with different values?
public void getAcctChgDataFromDB(String orderNo,String indicator){
     if((rs == null) ){
                   logger.equals("No rows returned for Order No " + orderNo);
                   throw new AcctChgException("No rows returned for Order No " + orderNo );
              }else
                             while(rs.next()){
                                  f_OrderID = rs.getString("FixOrderID");
                                  f_EffTs    = rs.getString("EffTs");
                                  f_ClrAcct = rs.getString("ClrAcct");
                                  f_MsgSeqNum = rs.getString("FixMsgSeqNum");
         } catch (Exception e) {
               e.printStackTrace();


well i fell
List<Map<String,Object>> or
List<CustomDTOBean>could be a specific data structure which you can look for.
where List would have reference to 5 Objects(Row) and each object could be a Map or a CustomDTO.If we consider map it would be like structure something like
key=TABLE_COLUMN_NAME
value=TABLE_COLUMN_VALUE

Urgent help please with MIDI pedal

I just got an old awesome midi pedal called the X-15 Ultrafoot.
The pedal has two expression pedals, and 10 pushbuttons/pads. (and two buttons to cycle through additional banks, and a "mode" and "bypass" button)
Somebody please help I am on the verge to having amazing control.
What I want to do is have each pushbutton be assigned to a parameter, which is easy to program. Then I want to make the expression pedal(s) also be assigned to that last selected parameter. How do I do this?
How can I make the expression pedals control over the parameter remain exclusive to just the last selected parameter?!
Somebody save me please thanks
