Default autocommit is true or false?
Hi, list!
A strange problem.
I have a session bean that access a datasource. When a connection is
requested and method Connection.getAutoCommit() is called, I always obtain
true. The default autocommit isn't false?
Stranger! See this code:
try {
Connection con = getConnection(); //obtain connection in datasource
con.setAutoCommit(false);
stmt.executeUpdate(sql1);
stmt.executeUpdate(sql2);
} catch(Exception) {
sessionContext.setRollbackOnly();
}
When stmt.executeUpdate(sql) throws a SQLException, my session bean calls
setRollbackOnly and the transaction should rollback. In fact, I saw that
stmt.executeUpdate(sql1) didn't have effect in database just after this
method have execute. But after about 1 minute, I turn to database and I saw
that the effect of stmt.executeUpdate(sql1) was commited.
I repeat the experiment many times, and the same occurred after one minute.
It sounds like the container had setted the autocommit true after some
timeout. Does anyone knows what is happenning? The default autocommit isn't
false?
