Hi ,

Mapping file work fine will inserting and updating the record , but gives problem will retrieving Objects.

Explanation : -

It gives me trouble while loading TCx1PtsiteT object .
1. while loading TA3PatientT object using TCx1PtsiteT object .
Description :-In database Tables TA3PatientT and TCx1PtsiteT have one-to-one relationship on Composite Id.TCx1PtsiteT have many-to-one relationship with TCx1ParticipantM & TCx1PatientT

Here i get the following Exception
SEVERE: IllegalArgumentException in class: .ge.med.registries.acc_30.hibernate.TA3PatientT, getter method of property: participant

In hbm I have defined like this:-

<class name="TCx1PtsiteT" table="T_CX1_PtSite_T">
<composite-id unsaved-value="any" >
<key-many-to-one name="Participant" class="TCx1ParticipantM" column="Participant_ID"/>
<key-many-to-one name="Patient" class="TCx1PatientT" column="PatID"/>
</composite-id>
<one-to-one name="accPatient" class="TA3PatientT" constrained="true" outer-join="false"/>
<bag name="admParticipant" inverse="true" lazy="true" cascade="all">
<key column="Participant_ID"/>
<one-to-many class="TCx1AdmdisT"/>
</bag>
<bag name="admPatient" inverse="true" lazy="true" cascade="all">
<key column="PatID"/>
<one-to-many class="TCx1AdmdisT"/>
</bag>
</class>

<class name="TA3PatientT" table="a3.T_A3_Patient_T">
<composite-id unsaved-value="any">
<key-property name="participant" type="string column="Participant_ID"/>
<key-property name="patient" type="integer" column="PatID"/>
</composite-id>
<one-to-one name="ptSite" class="TCx1PtsiteT" constrained="true" outer-join="false"/>
<property name="race" column="Race" type="short" length="5"/>
</class>

Help me out...

Use your debugger to find the cause of the exception. I am quite confident you wil be able to find the cause by yourself.

(You have anyway, given nowhere near enough information to solve this problem.)

Hi Gavin,

This is the Exception get generated will retrive the object :-

The code is like this
Query q = sess.createQuery(
"from TCx1PatientT as patient " +
"where patient.primary =:primary"
);
System.out.println(q.toString());
q.setInteger("primary",primary);
List list = q.list();
if(list.size()>0)
{
patient = (TCx1PatientT) list.get(0);
}
tx.commit();

System.out.println("*********************"+patient);
System.out.println("*********************"+(TCx1PtsiteT) patient.getSite().get(0));
site = (TCx1PtsiteT) patient.getSite().get(0);
System.out.println("*********************"+site.getPatient());
System.out.println("*********************"+site.getParticipant());

//Booms here
System.out.println("*********************"+site.getAccPatient());

TA3Patient contain get and set property of particpant , then what can be reason of generation Getter property Exception.
For more information let me know

Devesh

probably your get/set pair is of the wrong type (should be java.lang.String)

Define in TA3Patient class

public String getParticipant() {
return this.participant;
}

public void setParticipant(String participant) {
this.participant = participant;
}

then ?????

Use your debugger to find the problem.

If u see the mapping file

Table T_CX1_PtSite_T has one-to-one relationship with a3.T_A3_Patient_T

on two keys i.e. Participant_ID and PatID

and in case of one-to-one we cann't define column name on which there is one-to-one relationship as it is take care by Hibernate only.

I think that may be root cause of the problem

If so , what way I can define the relationship .
