"DatabaseSession databaseSession = (DatabaseSession )SessionManager.getManager().getSession("MySessionName");"
statment, the system report the following error:

the following is my session.xml context
<?xml version = '1.0' encoding = 'UTF-8'?>

1, The "TopLink" is my datasource to connect the sql server.
2, In JDeveloper 10g's connections navigator, I can use the "TopLink" to connect my database.
3, My program is non-server mode
Who can help me to solve the error?
