Inner classes mapped with composite-id not saving into database in Hibernate mapping

[Param Ramar]

I am trying to persist a jaxb object using hibernate into db. All the details in Notice & Document will go in one main table and Slip details will go into other table Below is the jaxb class.

public class Ticket
    implements Serializable, Equals, HashCode
{
    protected Ticket.Transaction transaction;   
    // Getter, setter for transaction & override methods.   
    public static class Transaction
        implements Serializable, Equals, HashCode
    {
        protected Ticket.Transaction.Notice notice;
        protected Ticket.Transaction.Document document; 
        protected List<Ticket.Transaction.Slip> slip;
        // Getter, setter & override methods.               
         public static class Document implements Serializable, Equals, HashCode
        {
            protected String primaryKeyNumber;
            protected String transactionCode;
            protected String transactionType;           
            protected Ticket.Transaction.Document.Details details;          
            // other stuff
        }       

        public static class Notice implements Serializable, Equals, HashCode
        {
            protected String event;          
            protected String eventType;          
            // other stuff
        }
        // other stuff
    }
}

My hbm mapping files:

Ticket.hbm.xml

<hibernate-mapping> <class name="com.xml.Ticket" table="Document_Table" lazy="false" > <composite-id name="transaction" class="com.xml.Ticket$Transaction" > <key-many-to-one name="document" class="com.xml.Ticket$Transaction$Document" column="primaryKeyNumber" /> </composite-id> </class> <class name="com.xml.Ticket$Transaction" table="Document_Table" > <composite-id name="document" class="com.xml.Ticket$Transaction$Document" > <key-property name="primaryKeyNumber" > <column name="primaryKeyNumber" ></column> </key-property> </composite-id> <component name="notice" class="com.xml.Ticket$Transaction$Notice" unique="true" > <property name="event"column="Event" ></property> <property name="eventType"column="EventType " /> </component> <bag name="slip" table="Slip_Table" cascade="all" inverse="true"> <key column="SlipNumber"/> <one-to-many class="com.xml.Ticket$Transaction$Slip"/> </bag> </class> </hibernate-mapping>

Document.hbm.xml
<hibernate-mapping > <class name="com.xml.Ticket$Transaction$Document" table="Document_Table" lazy="true" > <id name="primaryKeyNumber" column="primaryKeyNumber" > </id> <property name="transactionCode" column="TransactionCode" /> <property name="transactionType" column="TransactionType" /> <component name="details" class="com.xml.Ticket$Transaction$Document$Details" > <property name="taNumber" column="TaNumber" /> <property name="code" column="Code" /> </component> // Other stuff </class> </hibernate-mapping>

When i call session.save(ticket) It is saving only the the primaryKeyNumber in Document table not saving other details in Notice & Slip details

Below is the query generated in log

SQL] - insert into Document_Table (primaryKeyNumber) values (?) Hibernate: insert into Document_Table (primaryKeyNumber) values (?)

Ideally the query should insert all values from Ticket,Document & Notice values and also should generate separate queries to insert Slip Details into Slip_Table like below

Hibernate: insert into Document_Table (primaryKeyNumber,event,eventType,transactionCode,transactionType ) values (?,?,?,?,?)

if I call session.save(ticket.getDocument()) , then document details are recorded in the table without any Notice & slip details

Please help me to find where I have gone wrong here.
