we are successfully using Sybase with PersistenceBroker (no ODMG) however this shouldn't be a problem.
depending on your Sybase version you should try to use platform="SybaseASE" instead of "Sybase" in your connection descriptor.
this solved our problems (we also were using platform="Sybase" at the beginning)

Hi, I tried to use ojb with Sybase, it did not work.
but the same code worked fine with mysql and sql server.
I wanted to do an easy retrieve from the Sybase,I met an Exception that is "[org.apache.ojb.odmg.collections.DListImpl] ERROR: Generation of new id failed
ConnectionManager is NOT in transaction" .
Here is my code,xml and Exception , anyone can give me some clue to solve this problem which puzzle me two days.
CODE:
public static List retrieveBook(String bookName){
Implementation impl = OJB.getInstance();
Database db=impl.newDatabase();
try {
db.open("webpublishSybase",db.OPEN_READ_ONLY);
} catch (ODMGException e) {
e.printStackTrace(); //To change body of catch statement use Options | File Templates.
}
List list=null;
Transaction tx = impl.newTransaction();
try{
tx.begin();
OQLQuery query = impl.newOQLQuery();
query.create("select results from "+Book.class.getName()+" where bookName like $1 ");
query.bind(bookName);
DList results = (DList) query.execute();
tx.commit();
list=results;
}catch(Exception e){
e.printStackTrace();
tx.abort();
}finally{
try {
db.close();
} catch (ODMGException e) {
e.printStackTrace(); //To change body of catch statement use Options | File Templates.
}
}
return list;
}
