Failed using dynamically created datasources

[developer72]

Hi,

im using WAS 5.0 and my application creates datasources dynamically which works. (see code #1)
After the datasource has been created I look it up via jndi (see code #2) and try use it (e.g. get a connection), but here I get an exception (see stacktrace #3).

I found out, that WAS needs a Version 5 datasource for ejb 2.0. But when I create a datasource dynamically I can not set the version of the datasource to create and somehow WAS create a version 4 datasource.

How can I dynamically create a version 5 datasource?
Is one of you also using the datasource factory? How do you do it?

All tips are very welcome.

regards,

oliver

// Create a properties file for the DataSource
java.util.Properties prop = new java.util.Properties();
prop.put(DataSourceFactory.NAME, dataSourceIdentifier);
prop.put(DataSourceFactory.DATASOURCE_CLASS_NAME, "oracle.jdbc.pool.OracleConnectionPoolDataSource");
prop.put(DataSourceFactory.USER, inDataSourceProperties.getUsername());
prop.put(DataSourceFactory.PASSWORD, inDataSourceProperties.getPassword());
prop.put("URL", inDataSourceProperties.getConnectionURI());

// Obtain a DataSource from the factory
try {
dataSource = DataSourceFactory.getDataSource(prop);
}
catch (Exception e) {
System.out.println("Exception:");
e.printStackTrace();
}

// Bind the DataSource into JNDI
try {

DataSourceFactory.bindDataSource(initialContext,dataSource);
}
catch (NamingException ne) {
System.out.println("NamingException: " + ne.getMessage());
}

#2
try {
dataSource = (javax.sql.DataSource)initialContext.lookup("thisNode/servers/server1/"+dataSourceIdentifier);
System.out.println("Datasource exists and was successfully looked up over jndi!");
}
catch (NamingException ne) {
ne.printStackTrace();
}
