Using postgre on Jboss EJB Entity bean

[giscard_aioba]

Hi guys, I am here again, and I have another "simple"question (I swear that I won't do these kind of question as soon as...:-)

Well, I am developing a simple entity bean, but I don't know how to bind my resource database(setted on the ejb-jar.xml file) with a jar driver file and the postgresql database!!!!! Where I point the jboss to use the postgre and where I set the "jndi name to access it".

Well, if anyone can point me a tutorial or online documentation will be very helpful too....

Thanks all

I use XDoclet to generate those relevant DD for the entity beans. Have a look at http://xdoclet.sourceforge.net/xdoclet/index.html

Look at @ejb and @jboss tag if you're using JBoss as the app server.

Sample usage will be (at the bean implementation class):

Not all tags needed is in this sample
/**
* @ejb.bean name = "AnEntity"
* type = "CMP"
* display-name = "AnEntity"
* description = "AnEntity EJB"
* view-type = "remote"
* jndi-name = "ejb/AnEntity"
* primkey-field = "id"
*
* @jboss.cmp-field field-name="id" column-name="Id"
* @jboss.cmp-field field-name="column2" column-name="column2"
*
* @jboss.persistence
* datasource="java:/PostgresPool"
* datasource-mapping="PostgreSQL"
* table-name="table_name"
*/
public abstract class AnEntity implements EntityBean {
...
...
}

[Note] The '@jboss.persistence' is where you declared your bean to map to which datasource and table.

Hope this help.
