Hi I'm using eclipselink 1.0.2 from Jdeveloper 11.1.0.1 and MySQL as database.
I'm running a java client to test the written functionality in a Session Bean deployed to weblogic server (default in jdeveloper).
and I'm getting the error
[code]

Here is my fetchLocation() method:
public IPGroupCity fetchLocation(String ip){
//String sql="SELECT * FROM `ip_group_city` where `ip_start` <= ((INET_ATON(?1))/256) order by ip_start desc limit 1";
Query query = em.createNamedQuery("findLocationForIP");
int ipNumber = GeoIPUtils.convertIPStringToNumber(ip);
query.setParameter("ipNumber",ipNumber);
query.setHint("eclipselink.jdbc.fetch-size",1);
IPGroupCity location= (IPGroupCity) query.getSingleResult();
return location;
}[/code]
Can you help me find out why eclipselink could not fetch the result of my query?
and what I need to to do to fix this...
Thanks and Regards,
Samba
