OJB hang

Hello everyone,

I am using ojb 1.0.4 in weblogic 8.1.5 on HP unix, I use ojb to retrieve 
data from a database view. However, when record is few, the retrieve is 
OK. But if the record is bigger, ojb will hang. My retrieval is like 
this:
ReportQueryByCriteria query =
        QueryFactory.newReportQuery(ShipmentViewImpl.class, crit);
Iterator iter = broker.getReportQueryIteratorByQuery(query);

The query will hang at the getReportQueryIteratorByQuery() statement.

Anyone can give me any suggestion to solve this problem.

Best Regards
Feng Qiang
