You could use a GlobalNamingResources datasource db connection pool which would be available to all your servlets via a ResourceLink, rather than a servlet.

All other servlets can than access this object via getServletContext.getAttribute() etc. This servlet is defined as a servlet, loaded on initialisation. You must release that the init() method of this servlet can be called multiple times, especially if web.xml is changed. To avoid any dramas, make sure that the init() is singleton (ie it only operates once). Same applies to the destroy() To be safe, make sure the get() and post() methods of the servlet do something like redirect the response to another web page. I know this approach works. Hope this helps Bill -----Original Message----- From: Andreas Byström [mailto:[EMAIL PROTECTED] Sent: Friday, 7 March 2003 9:20 PM To: Tomcat Users Subject: Share Java resources between two (or more) servlets Hi all! I'm writing an application that uses (for now) 4 different servlets. I would like all these servlets to share some java singelton object. Is this possible? Do all servlets share the same jvm instance and thereby uses the same singelton object? I have one servlet that is set to load-on-startup, this servlet will create the java object (db connections and other stuff) that I want all servlets to share later on. This servlet is not used anymore, it hust listens for shutdown and will not receive any requests. Is this how you should solve a initialization problem or is there some other way? When I run my application I start this servlet (servlet1) as above. But when I then invoke another servlet, servlet2, (that is not set to load-on-startup) there is a strange behavior. Using my traces I can read that it first invokes init on servlet1 again and then init on servlet2. If I then sends a first reuquest to servlet3 it just does init on servlet3. If I instead had sent the first request to 3 before the first request to servlet2 it is the same behavior but vice versa. when the request comes to servlet3 it does init on first 1 nd then 3. The request to servlet 2 now just incokes init on servlet2. Have anyone a clue of you it can be like this? // Andreas ____________________________________ Andreas Bystrom Computer Engineer e-horizon Streaming Technologies Stadshusplatsen 2, 4th floor Box 172 SE 14922 Nynashamn mail : [EMAIL PROTECTED] web : www.e-horizon.se phone : +46 8 524 201 80 mobile: +46 708 85 23 35 ____________________________________ --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
