Hi,

Hibernate version:

3.1

Mapping documents:

CertCartons.hbm.xml

Code between sessionFactory.openSession() and session.close():


List alReasons = hibSession.createCriteria(CertCartonsDTO.class,"carton")
.createAlias("certPallets","cp") //association path with alias
.setProjection(Projections.projectionList()
.add(Projections.property("carton.ccCartonNo"),"ccCartonNo")// working well
.add(Projections.property("cp.cpPalletNo"),"certPallets.cpPalletNo")) // Not working for many-to-one
.add(Property.forName("carton.ccCartonNo").eq(new String("CA89374238")))
.setResultTransformer(new AliasToBeanResultTransformer(CertCartonsDTO.class)).list();
System.out.println("The list size is what???"+alReasons.size());
for(int i=0;i<alReasons.size();i++){
oCertCartonsDTO=(CertCartonsDTO)alReasons.get(i);
System.out.println("The oCertCartonsDTO.getCcCartonNo() is what???"+oCertCartonsDTO.getCcCartonNo()); //getting the value
System.out.println("The oCertCartonsDTO.getCertPallets().getCpPalletNo()is what???"+oCertCartonsDTO.getCertPallets().getCpPalletNo()); //null
}

Name and version of the database you are using:

Oracle 9.1

The generated SQL (show_sql=true):

Hibernate: select this_.CC_CARTON_NO as y0_, cp1_.CP_PALLET_NO as y1_ from CERT_CARTONS this_, CERT_PALLETS cp1_ where this_.CC_PALLET_NO=cp1_.CP_PALLET_NO and
this_.CC_CARTON_NO=?




I am not able to retrieve the values for the many-to-one relationships
where i am able to retrieve values for one-to-one relationships..

Where the getters and setters are rightly defined as well. Where
i have also tried fetch="join" in .hbm.xml still iam not able to retrieve the value for many-to-one.
Where the association path is correct(cp.cpPalletNo) where string after that to retrieve the value is : certPallets.cpPalletNo(which is CertCartonsDTO.certPallets.cpPalletNo) which is the one that is actually
giving the problem . But the string mapping seems to be right.


Please do provide a solution for this. I will be waiting for ur favourable
reply..



Thanks

What i need to do to get a reply from u folks????

No body knows???
