Try block inside a try block - who is throwing StaleConnectionException?

Question

int retry = 0;
try{ //MAIN TRY
//GET Datasource from context<---is this throwing?
boolean retry = false;
do {
     try {
          retry = false;
GET CONNECTION FROM DATASOURCE<--or shld this be?
     }catch(SQLException e) {
     //FIRST CATCH
     if (retryattempts++ < 3){
          retry = true;
} while (retry);
//DO something which requires try block
}catch(SQLException e)
{//Second catch
When I do this the StaleConnectionException is caught by the second catch... does this mean that the staleconnectionexception is thrown when getting datasource from initialcontext and not while getting connections?

Answer 1

I am not sure what your are trying to do. Your code as posted is incomplete and could not possibly compile. The Try/catches do not seem to be nested.
More importantly, why in the world would you ever want to have a try inside a try? You can have a single try, then several different calls in loops or whatever that can potentially throw Exceptions and then have mulitple catch statements to handle them. For instance, you could have something like this:
try {
} catch (NullPointerException ne) {
   // handle null issues here
} catch (NumberFormatException nfe) {
   // handle number format issues here
} catch (Exception e) {
   // everything else falls here
}Keep in mind that you don't want to do any "Error Hiding". Make sure you handle each case appropriately.
