I have seen an unanswered request pertaining to this error before.

Hibernate 2.1
DB2 7.2
Tomcat 5.0.19

I have set up a resource in the server.xml file and configured the Hibernate xml files as outlined in the user reference documentation "Quickstart with Tomcat." I have additionally set the hibernate.jdbc.batch_size = 0 as recommended for DB2. I am using the HibernateUtil class also outlined in the "Quckstart"

Here is my unique code in HibernateManager.executeQuery():
Session session = HibernateUtil.currentSession();
Transaction tx= session.beginTransaction();
Query query = session.createQuery(getQuery(userName));

for (Iterator it = query.iterate(); it.hasNext();) {
appUser = (AppUser) it.next();
System.out.println("AppUserId: " + appUser.getUserId() );
}

tx.commit();
HibernateUtil.closeSession();

private String getQuery(String userName) {
StringBuffer sb = new StringBuffer();
sb.append("from com.lat_inc.hibernate.pojo.AppUser appUser");
sb.append("where appUser.userId = " + userName);
return sb.toString();
}

The Error:

java.lang.AbstractMethodError: COM.ibm.db2.jdbc.net.DB2DatabaseMetaData.supportsResultSetType(I)Z

I find nothing in the log files except the above error. If there is anywhere else I can look please let me know.

Thanks

you have to use a JDBC 2.0 compatible driver, ist looks like you are using JDBC 1.2 compatible driver.
We use the driver from the DBConnect installation CD. There are to db2java.zip-files on the CD, use the one with the newer version of java in the pathname.
