Hello,
I'm trying to understand the problems/issues of using multiple DaoManagers in
the same application.
Say I have 2 jars:
MyApp.jar
TheirLib.jar
Both use Ibatis DAO. So, somewhere in their initialization, each makes a call
to DaoManagerBuilder.buildDaoManager(...) and keeps their DaoManager instance
somewhere.
If in a thread I call a method that uses the daomanager of MyApp and in the
same method I use the daomanager of TheirLib, won't the first commit of the 2
commit everything?
ie:
// Code in MyApp.jar
public void testMethod() {
daoManager_.startTransaction();
try{
doSomethingWithTheAppDaos();
TheirLibMethod(); <--- Somewhere in here there is a
theirLibDaoManager.commitTransaction();
daoManager_.commitTransaction();
}
finally {
daoManager.endTransaction();
}
}
Since the contexts/transactions are kept in the TLS (thread local storage)
doesn't multiple daomanager instances step on eachother (as long as they are
used in the same thread)?
Thanks
Louis
