Sorry, it sent the mail too early....
As I said, I wrote a jdo-conf.xml file compatible with my database and I'm
now trying to make the interact.
I wrote a little main which instanciates a person and tries to put it in the
database.
This is the code trying to save a person in the database (the person object
is called single).
*try
{
db=manag.getDatabase();
db.begin();
System.out.println("On a prepare");
}
catch(Exception e)
{ e.printStackTrace(); }
this.getCastorTemplate().create(single);
try
{
db.commit();
db.close();
}
catch(Exception e)
{ e.printStackTrace(); }
*
But every time, I get the Java Exception: No transaction in progress.
But I am instanciating the database and I begin the transaction before I try
to save.........
Does anyone know a solution to that ?
Best regards,
Jorrit Wortel
