How to set a datasource for a BIRT report programmatically?

Question

I have a BIRT report which connects to our test database. In the productive environment I would like to supply a datasource which is provided by the container through jndi.

Answer 1

This worked for me. I got the context and from context got the dataSource and passed the connection to Birt report like below

  Context initialContext = new InitialContext();
     if ( initialContext == null){
     System.out.println("JNDI problem. Cannot get InitialContext.");
        }
        DataSource datasource = (DataSource)initialContext.lookup("java:/datasources/SAMPLE");
     task.getAppContext().put("OdaJDBCDriverPassInConnection", datasource.getConnection());
