Adding a Datasource to a running Server ?

Question

What is the best way to add a new data-source to a running Server ?
Perviously, I was binding a new DataSource Object into the JNDI Tree from the context of an EJB, with an external process writing the new DataSource into the data-sources.xml file.
But now I've kicked EJB's out of the application, replacing with POJO's accessed from the servlet tier and the binding of the datasource fails (unusual issue and all my other Objects bind perfectly, I'll continue investigating...)
Now, I know that the admin.jar file can be used to manually add new data-sources to a server, but is this the best way to add data-sources to an already running server ?
Could I in some way call into the appropriate Class to add a new data-source.
e.g. A Server API like this: OC4JServer.addDataSource( Map params ); would be handy
Cheers,

Hello,
One way of doing that in OracleAS 10.1.3 will be to use JMX and MBeans.
The getMBeanServer() returns you an MBean Server connection where you can invoke operations as follow:
String appBeanName = "oc4j:j2eeType=J2EEApplication,name="+ j2eeAppName +",J2EEServer=standalone";
ObjectName obj = new ObjectName(appBeanName);
// invoke the create connection pool and create connection
// values used to create the connection pool
Object[] paramsPool = {
connectionPoolName,
dataSourceFactory,
username,
password,
url};
// signature used to create the connection pool
String[] signaturePool = {
"java.lang.String",
"java.lang.String",
"java.lang.String",
"java.lang.String",
"java.lang.String"};
// Call the connection pool creation operation
getMBeanServer().invoke(
obj,
"createJDBCConnectionPool", //operation
paramsPool,
signaturePool);
// Values used to create the connection
Object[] paramsConn = {
connectionName,
username,
password,
"jdbc/"+ connectionName,
new Integer(30), // timeout
connectionPoolName,
"global",
null};
// Signature used for the Operation call
String[] signatureConn = {
"java.lang.String",
"java.lang.String",
"java.lang.String",
"java.lang.String",
"java.lang.Integer",
"java.lang.String",
"java.lang.String",
"java.lang.String"
getMBeanServer().invoke(
obj,
"createManagedDataSource",
paramsConn,
signatureConn
