In that case, the simplest thing to do would be
1:Step 1:Commit
try {
2:Call method 1
3:call method 2
}catch(Throwable t){
rollback;
}
4:commit.
finally{
close connection;
}
As u can see, if u do a commit just before method call1, its like u are starting a new
transaction.
And u issue next commit only if m1 and m2 succeed else u rollaback to the previous
state(prior to m1)
HTH.

Shirish

Guess you have understood in wrong way.
Both are NOT data base methods, they could be any Java methods. I am not
talkin database txns. it's java transactions !!
I hope it make it clear.

|If you r using the same connection for both the methods, then u can
|rollback. I wud suggest you to do sth like this
|Main method()
|{
|Open ur connection
| Method1(pass connection object);
| Method2(pass connection object);
| Rollback or commit the connection based on ur exceptions etc.
|Close the connection
|}
|
|I guess the above shud be doable.
