Answer 1

Finally could able to commit transaction using MULE JPA transport, by creating CustomTransactionFactory which starts the transaction.

public class CustomTransactionFactory implements TransactionFactory{

@Override
public Transaction beginTransaction(MuleContext muleContext)
        throws TransactionException {
    EntityManagerFactory emf = muleContext.getRegistry().lookupObject("entityManagerFactory");
    TransactionFactory tf = new JPATransactionFactory();

    Transaction tx = tf.beginTransaction(muleContext);
    tx.bindResource(emf, emf.createEntityManager());
    tx.begin();
    return tx;
}

@Override
public boolean isTransacted() {
    return true;
}

}

By referring custom transaction manager in In-bound endpoint as below, we can achieve flow level transactions.

 <flow name="jpa_exampleFlow1" doc:name="jpa_exampleFlow1">
    <http:inbound-endpoint exchange-pattern="request-response"   doc:name="HTTP" address="http://localhost:9090/jpa_example">
    <custom-transaction action="ALWAYS_BEGIN" factory-ref="transctionManager"/>

Note: Transactional blocks are no more required.

Here your console shows :- Hibernate: insert into contact (EMAIL, FIRSTNAME, LASTNAME) values (?, ?, ?) and your payload is :- {"firstName":"king","lastName":"verma","email":"vermaS@xxx.com","id":9} ... where this id:"9" will be accommodated ? your query has 3 fields firstname,lastname and email ..where as your payload contains firstname,lastname,email and id
