Re: auto reload of message resource and URL-rewrite
Hi, I am sorry for my "stupidity". Need to read more careful email, and what people ask. I have tried myself the following link: "http://localhost:8080/struts-example/admin/reload.do" and it works. I can see messages about updating of ActionFormBean, ActionForward,... properties on a command line (where I have started Tomcat) and in browser window the message - "OK".

Re: auto reload of message resource and URL-rewrite
I got the URL loaded finally. I need to create the directory 'admin' myself before calling .../admin/reload.do . Oops!

I viewed the source it the IMG_SRC is "/struts-example/struts-power.gif;jsessionid=nhiizz1yq1". May I know why URL-rewrite is invoked for my browser, which cookie capability is properly enabled? I didn't answer the other half of this question in my previous response, so here is some background on why the URL rewriting takes place (even though you have cookies enabled). When a session is first created, the servlet container does not yet know whether the client browser supports cookies. Therefore, the only safe thing to do on that initial response is to send the session id *both* ways (URL rewriting and a cookie), and see what comes back in on the next request. If the cookie does not come back, the container says "aha, this client does not support cookies, so I will continue to use rewriting". The image is loaded successfully when I pressed "reload" on my browser. The string ";jsessionid*" is gone. That is because, on the subsequent request, your browser sent the session id cookie along. Therefore, the servlet container knows that you support cookies, and it stops adding the session ID with URL rewriting. -- Kan LEUNG, M K email: [EMAIL PROTECTED] Digital Empires Company Limited Craig

The image is loaded successfully when I pressed "reload" on my browser. The string ";jsessionid*" is gone. What servlet container are you using? Some containers (such as Tomcat 3.2 running behind Apache) do not correctly deal with URL-rewritten session ids unless you modify their configuration slightly -- in this case, you have to define a "rewrite rule" in the Apache configuration file to make it work. The details are in the Tomcat FAQ-O-MATIC, which you can reach via http://jakarta.apache.org. Search for an entry containing the words "URL rewriting" and you will find the setup details. -- Kan LEUNG, M K email: [EMAIL PROTECTED] Digital Empires Company Limited Craig McClanahan
