Commit crashes on bdbxml transaction

Question

Hi,
I'm trying to perform a simple transaction for my xmlcontainer, but everytime i try to commit my transactions, my program crashes, it goes to the dbgheap.c then says that i have an unhandled exception. Here's my snippet:
int mySample()
String theContainer = "name";
String path2DbEnv = ".";
DbEnv env(0);
env.set_cachesize(0, 64*1024*1024, 1);
env.open(path2DbEnv.c_str(),
DB_INIT_MPOOL | DB_CREATE | DB_INIT_LOCK |
DB_INIT_LOG | DB_INIT_TXN, 0);
XmlManager mgr(&env);
XmlTransaction containerTxn = mgr.createTransaction();
XmlContainer container = mgr.createContainer(containerTxn, theContainer);
containerTxn.commit();
return 0;
// i just removed the try catch stuff, but other than that, what did i do wrong? did i miss something?
thanks,
Chesca

Hi,
I modified your code to get it to run. I am not seeing the exception. Note that if you use createContainer and the container already exists, an exception is thrown.
Try the following, and if that still causes an error, see if you can get an error message from the exception and a stack trace.
Here is what worked for me:
Ron
int test1 ()
std::string theContainer = "name";
std::string path2DbEnv = ".";
try
DbEnv env(0);
env.set_cachesize(0, 64*1024*1024, 1);
env.open(path2DbEnv.c_str(),
DB_INIT_MPOOL | DB_CREATE | DB_INIT_LOCK |
DB_INIT_LOG | DB_INIT_TXN | DB_RECOVER, 0);
XmlManager mgr(&env);
XmlTransaction containerTxn = mgr.createTransaction();
XmlContainer container = mgr.openContainer(containerTxn, theContainer, DB_CREATE);
containerTxn.commit();
container.close();
env.close(0);
std::cerr << "Success! ";
catch(std::exception &e) {
          std::cerr << "Exception. ";
          std::cerr << e.what() << "\n";
          exit( -1 );
return 0;
}
