could not deserialize

[Arief Setiawan]

Hi All,

I'm begginer in hibernate. help me, please...


I have Inbox class as shown below:

 
public class Inbox{
private BigInteger inboxid;
private String inboxfrom;
private String inboxto;
public Inbox() {super();}
 
public Inbox(BigInteger inboxid) {
super();
this.inboxid = inboxid;
}
 
public Inbox(BigInteger inboxid, String inboxfrom, String inboxto)
{
super();
this.inboxid = inboxid;
this.inboxfrom = inboxfrom;
this.inboxto = inboxto;
}
 
public BigInteger getInboxid() {return this.inboxid;}
public void setInboxid(BigInteger value) {this.inboxid = value;}
public String getInboxfrom() {return this.inboxfrom;}
public void setInboxfrom(String value) {this.inboxfrom = value;}
public String getInboxto() {return this.inboxto;}
public void setInboxto(String value) {this.inboxto = value;}
}

This is my mapping:

 
<hibernate-mapping schema="MYSCHEMA" package="com.mypackage.data.hibernate">
  <class name="Inbox" table="INBOX" schema="MYSCHEMA" optimistic-lock="none">
    <id name="inboxid" type="big_integer" unsaved-value="null">
      <column name="INBOXID" not-null="true" unique="true" index="PK_INBOX" precision="22" scale="0"/>
      <generator class="assigned"/>
    </id>
    <property name="inboxfrom" type="string" column="INBOXFROM" length="50"/>
    <property name="inboxto" type="string" column="INBOXTO" length="250"/>
  </class>
</hibernate-mapping>

the problem is when i try to get column except primary key
i get this error :

org.hibernate.type.SerializationException: could not deserialize
at org.hibernate.util.SerializationHelper.deserialize(SerializationHelper.java:217)
at org.hibernate.util.SerializationHelper.deserialize(SerializationHelper.java:240)
bla...bla...bla...
Caused by: java.io.StreamCorruptedException: invalid stream header
blablabla...


this is my source code:

 
Session hSession = HibernateHelper.openSession();
hSession.beginTransaction();
Inbox ibx = (Inbox)hSession.load(Inbox.class,inboxid);
System.out.println("inboxid : " + ibx.getInboxid().toString());//work fine
System.out.println("inboxfrom : " + ibx.getInboxfrom());//error
System.out.println("inboxto : " + ibx.getInboxto());

any idea to get inboxfrom and inboxto ?

Your Inbox class needs to implement the Serializable interface.

thanks Paul for add code tag & Mark for your response

i have already implement Selializable interface in my Inbox class

public class Inbox [B]implements java.io.Serializable[/B]{
    //blablabla...
}

but i still got same error

I'm sorry, this is my fault

actualy, my table contain clob field, and i think that's no sense in this case. But i was wrong.
this field has generated as serializable field.
I change field mapping to clob, and at Inbox class to java.sql.clob.
no error anymore...


Thank's all
