Try using com.evermind.sql.DriverManagerDataSource as your datasource class and set your max-connections. Look it up using your ejb-location and setting it to the standard DataSource interface. Orion will pool the connection automatically. Since you are using BMP, remember to close your connection.

Subject: Oracle database and connection pooling
Hi,
I am new to EJBs so I apologize if my question sounds silly. I am trying to
configure Orion to use Oracle 8 and pooled connections.
This is how my data-source looks like:
<data-source
class="com.evermind.sql.ConnectionDataSource"
ejb-location="jdbc/MyApollo"
location="jdbc/OracleCoreDS"
pooled-location="jdbc/OraclePooledDS"
name="Oracle"
schema="database-schemas/oracle.xml"
xa-location="jdbc/xa/OracleXADS"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="system"
password="manager"
url="jdbc:oracle:oci8:@APOLLO"
inactivity-timeout="30"
/>
I am trying to implement a BMP and here is the code I am using to get the
connection:
public void setEntityContext(EntityContext ec)
{
...
Context initialContext = new InitialContext();
ConnectionPoolDataSource dataSource = (ConnectionPoolDataSource)
initialContext.lookup( "jdbc/OraclePooledDS" );
}
and later on
public Connection getConnection() throws SQLException
{
...
return dataSource.getPooledConnection().getConnection();
}
I get the folowing exception in my client code when I create the bean
javax.ejb.EJBException: com.evermind.sql.OrionPooledDataSource
at com.evermind.server.rmi.ba.invokeMethod(JAX)
at com.evermind.server.rmi.a1.invoke(JAX)
at com.evermind.server.rmi.a2.invoke(JAX)
at __Proxy2.create(Unknown Source)
at SelectTestClient.main(SelectTestClient.java:117)
that seems to be thrown
when the execution reaches the following line of code:
ConnectionPoolDataSource dataSource = (ConnectionPoolDataSource)
initialContext.lookup( "jdbc/OraclePooledDS" );
Thanks!
Danut
