Hi jboss,
I found following articles to use Value Object with CMP:
http://xdoclet.sourceforge.net/valueobjects.html
I feel it's greate and I immediately tried it with JBoss 3.2.1(+Tomcat
4.1.24) and JBossIDE 1.2.0. However I user getter/setter for Value
Object(named AddressValue), I got following error message:

I guess method for VO doesn't related field and it cause error. How
can I use VO setter/getter with JBoss? My code is like this:
/**
* @ejb.bean
* description = "Address Entity Bean"
* name = "Address"
* type = "CMP"
* cmp-version = "2.x"
* view-type = "remote"
* jndi-name = "ejb/address"
* primkey-field = "userid"
*
* @ejb.transaction
* type = "Required"
*
* @ejb.value-object
* name = "Address"
* match = "*"
*
* @ejb.persistence
* table-name = "address"
*/
public abstract class AddressBean implements EntityBean {
/** @ejb.interface-method */
public abstract void setAddressValue(AddressValue address);
/** @ejb.interface-method */
public abstract AddressValue getAddressValue();
// following are general CMP setting......
/** @ejb.interface-method
* @ejb.pk-field
*/
public abstract String getId();
/** @ejb.interface-method */
public abstract void setId();
/**
* @ejb.interface-method
* @ejb.persistence
* ...
*/
public abstract String getParam();
/** @ejb.interface-method */
public abstract void setParam();
...
