hi ,
i have two tables, A parent and the child relation exists between them.
The child table has a composite key.

The problem i m facing is that while saving the parent child is not getting saved.

Here are the HBM files.
***********************

Dcuments.hbm(PARENT)

<hibernate-mapping >

<class name="dams.ds.cust.Documents" table="DOCUMENTS">
<id name="docID" column="DOC_ID" type="int" unsaved-value="any">
<generator class="sequence">
<param name="sequence">pk_sequence</param>
</generator>
</id>
<property name="state" column="STATE" />
<set name="custPageStates" lazy="false" cascade="all">
<key column="DOC_ID"/>
<one-to-many class="dams.ds.cust.CustomizationStatus"/>
</set> </class>

</hibernate-mapping>

CustomizationStatus.hbm(CHILD)


<hibernate-mapping >

<class name="dams.ds.cust.CustomizationStatus" table="CUSTOMIZATION_STATUS">
<composite-id>
<key-many-to-one name="document" class="dams.ds.cust.Documents" column="DOC_ID"/> <key-property name="pageNo" column="PAGE_NO" />
</composite-id>
<property name="status" column="STATUS" />

this.custPageStates.add(custPageState);

this.docID = docID;

CustomizationStatus.java


public class CustomizationStatus implements Serializable
{
private int pageNo;

private Documents document = null;

private String status = null;

public void setPageNo(int pageNo)
{
this.pageNo = pageNo;
}

public int getPageNo()
{
return this.pageNo;
}

public void setDocument(Documents document)
{
this.document = document;
}

public Documents getDocument()
{
return this.document;
}
public void setStatus(String status)
{
this.status = status;
}

public String getStatus()
{
return this.status;
}

public boolean equals(Object other)
{
if (other == this)
return true;
if (other != null && other.getClass().equals(this.getClass()))
{
CustomizationStatus that = (CustomizationStatus) other;
if (this.getDocument().getDocID() == that.getDocument().getDocID()
&& this.getPageNo() == that.getPageNo())
return true;
else
return false;
}
return false;
}

public int hashCode()
{
String hashString = this.getDocument().getDocID() + "_" + this.getPageNo();
return hashString.hashCode();
}
}



-------------
Here is the code i m using to set the objects

i m getting 'numPages' from another method


Documents doc = new Documents();
CustomizationStatus custStatus = null;
for (int pageNo = 1; pageNo <= numPages ; pageNo++)
{
custStatus = new CustomizationStatus();
custStatus.setDocument(doc);
custStatus.setPageNo(pageNo);
custStatus.setStatus("needs-customization");

doc.addCustPageState(custStatus);

}

now i m passing this documents object i.e. doc to another method, where i m opening a session and saving the Documents object.


Session session = getNewSession();//to open a new Session
Transaction tx = session.beginTransaction();

session.save(document);

tx.commit();

if (session != null)
{
sesson.close();
}
