modify web deployment descriptor at runtime
Is there a way to modify web deployment descriptor (web.xml) at runtime using MBeans? I would like to add security roles/ constraints at runtime by providing a admin interface, so admin can add /remove users described in web.xml. Appreciate your replies.

How Servlets work?
Hi all, may be not the right place to ask this question. Hope somebody is kind enough to clarify this doubt of mine. i understand, in a servlet, if i need any code to be thread safe, then i shud put that code inside a synhronized block or declared the entire method as synchronized. if my understanding is right, only instance of our serlvet class is being created. in that case how the webserver handles more than one request at the same time. i mean, is some queuing structure being followed, (i am tempted to believe it is not multithreaded)? Could anybody clarify this doubt of mine or atleast point out some ref. material for this.

Re: How Servlets work?
Thanks a lot Harry. Thank you so much. Saravanan Harry Mantheakis wrote: Hello how the webserver handles more than one request at the same time. The answer is: by invoking the servlet's service method in a new thread for each new request to that servlet. Think of any Java object, instantiated once - a public method in that object can be called any number of times, concurrently. Each invocation will be processed in a new thread. Synchronisation is an issue only when the method in question uses references to other objects. If the method only works with local variables, there is no synchronisation problem! So, in a nutshell: with servlets, make sure the service method only uses local variables, including, of course, those two most useful parameters, the request and the response objects.

Or maybe the NIC is doing this. Many years ago when I did hardware testing, we first ran into TCP/IP stacks that had this optimization. The other thought is that for some reason different maximum packet sizes are being used with these different connections? Of course, this is just a theory. Someone with a little more knowledge might be able to speak more authoritatively grin. dwh Saravanan Bellan wrote: Windows 2000 Tomcat 3.2.3 If I try to upload a file using the regular HTML/HTTP, there is a 20x difference in performance between using localhost vs the IP address in the Web Server URL.

localhost vs IP address in the URL
Sorry, if this is a duplicate. Windows 2000 Tomcat 3.2.3 If I try to upload a file using the regular HTML/HTTP, there is a 20x difference in performance between using localhost vs the IP address in the Web Server URL.
