Seamgen reverse engineer, too many xml?

[philip142au.philip_andrew.hotmail.com]

Hi,

I have a seam-gen.reveng.xml file but I keep having to write the same XML over and over.

Is there a way to merge all this xml? I only want the onCreate and onUpdate so I can record the date time, for a lot of tables (not every table).

Thanks, Philip

  <table name="ticket" catalog="artawardscheme">
    <meta attribute="extra-import">javax.persistence.*</meta>
     <meta attribute="class-code">
@PrePersist
public void onCreate()
{
created = new Date();
updated = new Date();
}

@PreUpdate
public void onUpdate()
{
  updated = new Date();
}
     </meta>
  </table>
  <table name="user" catalog="artawardscheme">
    <meta attribute="extra-import">javax.persistence.*</meta>
     <meta attribute="class-code">
@PrePersist
public void onCreate()
{
created = new Date();
updated = new Date();
}

@PreUpdate
public void onUpdate()
{
  updated = new Date();
}
      
     </meta>
  </table>

Sorry that didn't format correctly.

  <table name="ticket" catalog="artawardscheme">
    <meta attribute="extra-import">javax.persistence.*</meta>
     <meta attribute="class-code">
@PrePersist
public void onCreate()
{
created = new Date();
updated = new Date();
}

@PreUpdate
public void onUpdate()
{
  updated = new Date();
}
     </meta>
  </table>
  <table name="user" catalog="artawardscheme">
    <meta attribute="extra-import">javax.persistence.*</meta>
     <meta attribute="class-code">

public void onCreate()
{
created = new Date();
updated = new Date();
}

@PreUpdate
public void onUpdate()
{
  updated = new Date();
}

Use a generic entityListener for all your classes, configured through orm.xml

orm.xml

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"
                 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm orm_1_0.xsd"
                 version="1.0"
        >
    <persistence-unit-metadata>
        <persistence-unit-defaults>
            <entity-listeners>
                <entity-listener class="com.mypackage.EntityListener">
                    <pre-persist method-name="prePersist"/>
                    <pre-update method-name="preUpdate"/>
                </entity-listener>
            </entity-listeners>
        </persistence-unit-defaults>
    </persistence-unit-metadata>

</entity-mappings>

not sure about the order, pre-update may need to be first.

The entity is passed to the entityListener method as an argument, so you can set the values there.

Also it is possible to hack up the templates that seam gen uses, but that requires a bit more effort.
