* You can use ServiceLocator to get a db connection if you define your conn as service via JNDI in the container:
ServiceLocator locator = ServiceLocator.getInstance(); myDBConn = locator.getDBConn(ServiceLocator.MY_DB); * Another usage can be getting JMS connection : queueConnection = locator.getJMSQueueConn(ServiceLocator.Q_CONN); * i don't see added value to lookup a Business Delegate which is not an EJB José. -----Original Message----- From: John Boyes [mailto:[EMAIL PROTECTED] Sent: Thursday, August 07, 2003 11:40 PM To: [EMAIL PROTECTED] Subject: Service Locator pattern useful if not using EJBs? I'm currently deciding on which design patterns to use for a Struts-based web application. Definitely going to use a Business Delegate to ensure a proper separation of the business and presentation tiers. Is it good practice to use a Service Locator to look up services for the Business Delegate? I can see the benefits of using a Service Locator when using EJBS, however I'm not going to use EJBs. Are there any other pertinent benefits in using a Service Locator, or is it an unneccessary extra level of complexity in a non-EJB implementation? Any replies much appreciated, John --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] **** DISCLAIMER **** "This e-mail and any attachment thereto may contain information which is confidential and/or protected by intellectual property rights and are intended for the sole use of the recipient(s) named above.
