Hi
  I have a problem in which I need to invoke a method on catching "ObjectNotFoundException".Now this invoked method also throws an exception; can I catch it in the same try/catch block ; cause nested try/catch are not allowed any way.

  try
  {
   //find something
   //update if found
   updateRow(arguments)
  }
  catch (ObjectNotFoundException e)
  {
   //insert some data in the database using a method
   // insertRow (which throws an exception insertException)

   insertRow(arguments);
  }
  catch (insertException e) //IS THIS ALLOWED ?????????
  {
  //do some logging
  }
  catch (updateException e)
  {
  //do some logging
  }

  I think this wont work ; cause (insertException) is not thrown in "try" block . what say u?

  Thanks

Jack


  

Hi
  I again checked my java knowledge base and its true that once a catch{} has been executed ; all other catch{} are ignored .So I guess "insertException" will be caught by the program which called the current program.
  Can there be any other way of handling this ; I mean the situation in which if an object is not found ; insert it.
  Thanks

Hi,

Let me know if this helps. You can create nested try catch block as follows

try
{
}catch(ObjectNotFoundException onfe)
{
   try
   {
   }catch(InsertException ie)
   {
   }
}

Cheers,

Hi
  Can i create nested try/catch block?I used to think that nested try/catch blocks are not allowed?
  Is it part of java 1.3? or I was ignorant of it?
Jack

this is definitely allowed, i've been using this in jdk1.2.

Hi
  can a catch block return to the calling program?

  I mean

  try
  {
   return 0 ;
  }
  catch (Exception e)
  {
   return 1 ;
  }


  I guess this is allowed?
  Sorry for this elementary questions ; havent programmed much in java ; so sometimes my fundamentals complain :-)
