Hi Oleg,
here are some code snippets from my bean:
private Database getDatabase() throws PersistenceException,
NamingException {
InitialContext ic = new InitialContext();
DataObjects jdo = (DataObjects) ic.lookup("java:comp/env/jdo/castor");
System.out.println("[IMOST] getDatabase current: " +
Thread.currentThread().getContextClassLoader());
Database db = jdo.getDatabase();
System.out.println("[IMOST] Database: " + db.getClassLoader());
return db;
}
public Collection ejbFindAll() {
ArrayList result = new ArrayList();
try {
Database db = this.getDatabase();
Query oql = db.getOQLQuery("SELECT o FROM de.imost.user.ejb.UserDO
o");
QueryResults qr = oql.execute();
while(qr.hasMore()) {
UserDO d = (UserDO) qr.next();
result.add(d.getLogin());
}
db.close();
} catch(Exception e) {
e.printStackTrace();
throw new EJBException(e);
}
return result;
}
public void ejbLoad() {
try {
login = (String) ctx.getPrimaryKey();
Database db = this.getDatabase();
data = (UserDO) db.load(UserDO.class, login);
db.close();
} catch(Exception e) {
e.printStackTrace();
throw new EJBException(e);
}
modified = false;
}
The debug messages are printed in getDatabase(). Some other messages
(UserDO and UserRightDO) are printed in the constructors of the
corresponding data objects.
