Chapter 15: Entity Beans and Table Mapping for CMP 2.0 157

Container-Managed Persistence in Borland Enterprise Server

<ejb-name>CustomerEJB</ejb-name>

<prop-name>ejb.datasource</property>

<prop-value>serial://ds/myDatasource</prop-value>

</property>

</entity>

The Borland CMP engine will automatically create tables in this datasource

based on the bean's name and fields.

CASE 2: A deployment environment with (or without) existing database tables

using supported databases.

In this case, you need to supply information on the tables to which the entities

map. You'll provide a table name in the <entity> portion of the descriptor, and

some properties in the <table-properties> portion:

<ejb-name>CustomerEJB</ejb-name>

<cmp2-info>

<table-name>CUSTOMER</table-name>

</cmp2-info>

</entity>

<table-properties>

<table-name>CUSTOMER</table-name>

<prop-name>datasource</prop-name>

<prop-value>serial://ds/myDatasource</prop-value>

</property>

</table-properties>

Note that the datasource property is called datasource when specified in the

<table-properties> element and ejb.datasource when in the <entity> element. If

you are using a database other than JDataStore or Cloudscape and would like

to have the Borland CMP engine automatically create this table, add the

following XML to the <table-properties> element:

<table-properties>

<table-name>CUSTOMER</table-name>

<prop-name>create-tables</prop-name>

<prop-value>True</prop-value>

</property>

</table-properties>
