Hi All

I am using hibernate 2.0.I am facing some problem with bidirectional relationship.
Here is my mapping file contents.

<class name="com.Text" table="TEXT">
<meta attribute="class-description">
Text
</meta>
<id name="sysKey" type="int" column="TEXT_SYSKEY">
<meta attribute="scope-set">public</meta>
<!-- This generator is used when the primary key is a natural key instead of a surrogate key-->
<generator class="native"/>
</id>
<property name="version" column="VERSION" type="int"/>
<property name="size" type="int"/>
<set name="Types" table="Types_Text_ASSOC" inverse="false" lazy="true" cascade="save-update">
<meta attribute="field-description">Types Associated with Text through Type_Text_Assoc table</meta>
<key column="TEXT_SYSKEY"/>
<many-to-many column="TYPE_SYSKEY" class="com.Type"/>
</set>
</class>


I am having collection Types in my class ,that is created for representing association between Type & Text.

Everything is working fine.But when i am updating the types of a Text object it is deleting all recrods from Type_Text_Assoc table and then inserting again.
It is not updating the data in table ,it should update the exiting and delete/insert other nwe/old elements.

It is a problem for me because a trigger is on my database on delete of any row from Type_Text_assoc table

Waiting for response

plz provide the implementation codes and class/mapping for both sides of association

Hi

Here is DAO class


package com.text;


import java.util.*;

/**

*/

public class Text
{
private Set types; // TYPES
private int version;
private int size;
private String sysKey;


public Set getTypes() {
return serviceInfoTypes;
}

public void setTypes(Set types) {
this.types = types;
}

public int getVersion() {
return version;
}

public void setVersion(int version) {
this.version = version;
}

public int getSize() {
return size;
}

public void setSize(int size) {
this.size = size;
}


public String getSysKey() {
return sysKey;
}

public void setSysKey(String sysKey) {
this.sysKey = sysKey;
}


}
