Java Development Tools

Hello,

A requirement for my current project (ADF 10g) is that a user should be able to log in with his regular database account. For the moment, this is implemented using Proxy Authentication, as described in the following article:

http://blogs.oracle.com/jheadstart/2008/01/using_proxy_authentication.html

For now, we are using a JDBC URL defined in the application module config for the BC. In short: a ProxyAuthConnectionPoolManager class was created that overrides the default ConnectionPoolManagerImpl. The getConnection method has been overridden to create a standard connection (with the username/pw defined on the AM), and additionally, create a proxy connection within this connection with the specific user credentials. The (simplified) code:

    public Connection getConnection(String key, String url, Properties props, String username, String pwd) {
        // first fetch a default connection from the pool through the superclass
        Connection connection = super.getConnection(key, url, props, username, pwd);
        // cast into an OracleConnection
        OracleConnection oraConnection = (OracleConnection) connection;
        ...
            // close any proxy sessions that would still exist on the connection
            if (oraConnection.isProxySession()) oraConnection.close(OracleConnection.PROXY_SESSION);
            // get a handle on the session scope
            Map sessionScope = ADFContext.getCurrent().getSessionScope();
            if (sessionScope != null) {
                // find the user object in the session (the account the user logs in with)
                ProxyAuthUser user = (ProxyAuthUser) sessionScope.get(ProxyAuthUser.JHS_USER_KEY);
                if (user != null) {
                    // create a property map with the end user credentials
                    Properties proxyProps = new Properties();
                    proxyProps.put(OracleConnection.PROXY_USER_NAME, user.getDbUsername() + "/" + user.getDbPassword());
                    proxyProps.put(OracleConnection.PROXY_USER_PASSWORD, user.getDbPassword());
                    
                    // open the proxy session
                    oraConnection.openProxySession(OracleConnection.PROXYTYPE_USER_NAME, proxyProps);
                } 
            }
            return oraConnection;  
    }

Now, this works perfectly when using a JDBC URL. But when I switch the JDBC Datasource the ProxyAuthConnectionPoolManager class is not called anymore. This is all done in code in the Application Server. While using a JDBC Datasource is actually necessary: otherwise for each environment (dev, test, production,...) a different WAR file is needed.

What class can I override with code similar to the piece above, to open a proxy connection inside the existing connection, when using a JDBC Datasource?

Your help would be greatly appreciated!
