I have two tables named Job and Jobpackage with many-to-one association. It means many jobs are asssociated with one Jobpackage.
I'm manually creating Javabean classes for both and using hiberantor to create .hbm.xml files out of it in WSAD 5.1.2. I'm manually adding the column names and association in .hbm.xml files. These .hbm.xml file are also added in hibernate.cfg.xml file where I have all database connection info.
Database tables already exist so I'm skipping schema generation part. I have a simple java class with one method for creating Job list from Job table. Also I have a servlet which invokes that method and pass it in the request object to jsp page where jsp page displays all the jobs from job table.
But when I run this program it get an error:
JobsBean.getJob(): Exception creating sessionfactory: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) setter of com.boeing.tsas.castle.data.transferobjects.JobPackage.?
Exception creating sessionfactory: No persister for: java.lang.Integer
I'm new to hibernate but already implemented it for one-to-one asssociation and that works very well. I'm sure that I'm missing something but have no idea. I'd appreciate immediate help to rectify this issue.
Here is the details:
