Hi all,
Each time when create a OQL Query with
OQLQuery query = odmg.newOQLQuery();
I get the following error message:
java.lang.NoClassDefFoundError: antlr/TokenStreamException
at org.apache.ojb.odmg.OJB.newOQLQuery(Unknown Source)
at
ch.lcu.mycoach.data.MemberFactory.getMemberDO(MemberFactory.java:56)
...
Whats wrong? The same query is working when I use the PersistenceBroker
implementation. Can anybody help me?
I'm working with ojb-1.0.rc4.
Thanks for your help!
Rolf
NB:This is the code of the MemberFactory class:
package ch.lcu.mycoach.data;
import org.apache.ojb.odmg.OJB;
import org.odmg.*
import ch.lcu.mycoach.entities.Member;
public class MemberFactory {
Implementation odmg = null;
Database db = null;
Member member = new Member();
public MemberFactory() {
// get odmg facade instance
odmg = OJB.getInstance();
db = odmg.newDatabase();
//open database
try {
db.open("mycoach", Database.OPEN_READ_WRITE);
} catch (ODMGException ex) {
ex.printStackTrace();
}
}
public Member getMemberDO(String username, String password) {
Transaction tx = odmg.newTransaction();
try {
// 1. open a transaction
tx.begin();
// 2. get an OQLQuery object from the ODMG
facade
OQLQuery query = odmg.newOQLQuery();
// 3. set the OQL select statement
String queryStr = "select members from " +
Member.class.getName();
queryStr += " where username = $1 adn password =
$2";
query.create(queryStr);
query.bind(username);
query.bind(password);
// 4. perform the query and store the result
// in a persistent Collection
DList members = (DList) query.execute();
member = (Member) members.get(0);
tx.commit();
} catch (Throwable t) {
// rollback in case of errors
tx.abort();
t.printStackTrace();
}
return member;
}
}
