Struts is in fact a servlet. Servlets do not need a main in order to run. Instead, they are registered with your servlet containers such as Tomcat. And then Tomcat will run them.

From: "O. Oke" <[EMAIL PROTECTED]> To put it another way, when I click a button in an HTML form, which "main" class kick starts the chain of processing that eventually leads to my action class being executed? The "entry point" for Struts is in the doPost (or doGet) method of org.apache.struts.action.ActionServlet. (Prior to that, your Servlet container did some work that you probably aren't interested in.) After ActionServlet, the [Struts 1.2.7] RequestProcessor will figure out which of your Actions it should call. The best way to see what really happens is to watch it in a debugger. I use JSwat, and have some instructions on how to get it working with Tomcat here: http://wiki.wsmoak.net/cgi-bin/wiki.pl?TomcatDebug Having set a breakpoint at the first line of the 'execute' method in my own action class, the stack shows: 1. ChooseProfileAction.execute() 2. RequestProcessor.processActionPerform() 3. RequestProcessor.process() 4. ActionServlet.process() 5. ActionServlet.doGet() 6. HttpServlet.service() ... all the way back to ... 47. Thread.run() HTH, -- Wendy Smoak - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I think you may have some misconceptions about how this whole Java thing works. Bottom line, there isn't one, which answers your question in a completely useless way. What do you really want to know? The entry point into a Struts Action (Action.execute)? How that Action gets mapped from a URL to a class (struts XML config files along with the default RequestProcessor)? How to understand the entire Struts framework? Dave - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Main class for a struts webapp...
it's somewhere deep inside the servlet container. I think what you need to look at is the action servlet, which is defined in the web.xml in a struts webapp O.

Main class for a struts webapp...
Can anyone please tell me where the "main" (public static void main...) class of a Strus web application can be found. To put it another way, when I click a button in an HTML form, which "main" class kick starts the chain of processing that eventually leads to my action class being executed?
