This is usually used on slow links, but I want to use it when my processing is slow. My servlet is doing some processing and is going to take some more time - how do I inform this to my client? Can I just set HttpServletResponse.setStatus (SC_CONTINUE)? (Can this response be sent more than once?) If this method is not right for the scenario, what is the recommended way of informing the client to patiently wait for some more time? 3. The response in HTTP/1.1 can have footers in addition to headers, how do I set a footer? I guess we cannot use HttpServletResponse.setHeader because the servlet spec says setting a header has no effect if the response is already committed. 4. Persistant connections - is this configurable in a tomcat? It might be the case that this is not something a user should bother about, the servlet container will take care of it. What does tomcat do?

Filter: Reading the http response content
In my filter I want to cache the content of
HttpServletResponse so that I can save that in a file
and use a static file's servlet for the next request.
However, I am not able find interface to get the
(html)content from the response object.
if (up2date) {
RequestDispatcher rd =
request.getServletDispatcher (static.html);
rd.forward (request, response);
}
else
{
chain.doFilter (request, response);
//***Then save the html response to static html
}
So any clues as to how to obtain the content of
response. The HttpServletResponse has methods to
get/set the HTTP headers and cookies, but does not
have anything for the HTTP's body. It is also not
possible to read from response.getOutputStream.
What do you guys think?

Serlvet init-param
Another question, a basic one: servlet servlet-nameservletone/servlet-name servlet-classmy.Servlet/servlet-class init-param param-namehi/param-name param-valuefoo/param-value /init-param /servlet servlet servlet-nameservlettwo/servlet-name servlet-classmy.Servlet/servlet-class init-param param-namehi/param-name param-valuebar/param-value /init-param /servlet I have two servlet-names defined above with the same Servlet class, the params are different. This setup actually works with me, but I dont know why it works. How many instances of my.Servlet are there in this case? is it two? or only one? Thank you, ~rf __ Do you Yahoo!? Yahoo!

Do something after the webapp starts
I want to do some[1] processing after my web application finishes starting completely, but before any servlet requests arrive. Are there any listeners for this situation? Q1. Does tomcat serve any requests before ServletContextListener.contextInitialized finishes execution? Q2.Is it correct to say that the application has fully started at the end of ServletContextListener.contextInitialized(ServletContextEvent) Q3. Are the static blocks in the servlet classes run after ServletContextListener.contextInitialized. [1] I want to deploy axis services programmatically after application starts. This is done by an AdminClient contacting the server. But the problem is that the server is not yet up! Where do you think should I do this deployment? thanks. __ Do you Yahoo!? Yahoo!

Re: what is catalina?..

I, personally, have no idea why this was chosen as a package name (I haven't been hanging out here that long). Especially since the principal author doesn't live in So. CA.

memory problem
I get OutofMemory with tomcat 4.0.6 and sun's jdk1.3. From the archives I found this is due to a bug in the sun's jdk 1.3 JVM, and people suggest to upgrade to 1.4 Does IBM's jdk1.3 too gives the same problem or is it only the Sun's?

HTTP Help
I am studying HTTP, and I have a question with this site http://www.omeda.com/ziff/ewk/ewk.cgi?t=whbackp=hpnav2 Fill the form here and submit. By using the HTTP debugger http://reitshamer.com/source/hds.html I found that IE sends two requests when this form is submitted. First, without the Submit button 'Continue'. It gets a response, it is not a 302 kind of response. Then it requests the same URL again, this time with the Continue button. Whats the matter here - I am not able to understand. Can somebody tell me? THANKS Rf __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

datewise catalina.out
While other log files are on a daily basis, catalina.out is not. Is there any configuration option, I use 4.0.6? Thanks, rf __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

get local port
InetAddress.getLocalHost().getHostAddress()gives the hostname, how to get the port number too? The port is 8080 in case of tomcat, but a different one with other app servers. What is the way to get this number at runtime? Thanks rf __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.
