Thanks guys for the help. The issue got resolved once I changed the POST action value to be the same as the value in the pattern. Just to make sure I understand the web.xml config better and to make sure I do the right thing in the future when I have to add additional servlets or such: * servlet name tag in the servlet tag and servlet-mapping tag should be the same. * The value of the url-pattern, welcome-file and the action value in the form tag should be all the same * I should have one set of servlet, servlet-mapping and welcome file for every servlet I use * I should never use / as a pattern because that is what Tomcat uses for static resources. * Can I have a url-pattern /foobar/foo2bar?

Re: Display of Static Resources
Hi, The problem for static resources went away. But now http is not able to find the servlet class when I click on the button on the form. This used to work before I changed the config in web.xml. So I am assuming this problem is related to what I have done in web.xml. Here is what is happening: * on http//localhost:8080, http invokes com.client.BizDispatcher. * The servlet constructs a login page and sends it to the browser. * Among other things, the login page has 2 submit, one login and the other cancel. * The form tag is as follows: o form method=POST action=com.client.BizDispatcher * I enter the user ID and password and click on the Login submit button. * I get a servlet error that says it is not able to find /com.client.BizDispatcher. Have I done something wrong in the config? * Here are the entries in my web.xml under ROOT\WEB-INF: ?xml version=1.0 encoding=ISO-8859-1? !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.3//EN http://java.sun.com/dtd/web-app_2_3.dtd; web-app display-nameWelcome to Tomcat/display-name description Welcome to Tomcat /description !-- JSPC servlet mappings start -- servlet servlet-nameorg.apache.jsp.index_jsp/servlet-name servlet-classorg.apache.jsp.index_jsp/servlet-class /servlet servlet servlet-namebizDispatcher/servlet-name servlet-classbizDNA.bizClient.bizBrowserClient.BizDispatcher/servlet-class /servlet servlet-mapping servlet-nameorg.apache.jsp.index_jsp/servlet-name url-pattern/index.jsp/url-pattern /servlet-mapping servlet-mapping servlet-namebizDispatcher/servlet-name url-pattern/bizDispatcher/url-pattern /servlet-mapping !-- JSPC servlet mappings end -- welcome-file-list welcome-filebizDispatcher/welcome-file welcome-fileindex.html/welcome-file welcome-fileindex.htm/welcome-file welcome-fileindex.jsp/welcome-file /welcome-file-list /web-app Thanks...Ram - Ram Sriram wrote: Hi, Thanks for all the help everyone.

Re: Display of Static Resources
For the most part, you should never need to edit the global web.xml file (the one under conf). Each app has it's own web.xml file stored under it's WEB-INF directory. Try removing your entries from the global one and put your servlet/mapping into the one under WEB-INF. My suspicion is that the problem is right here: !-- The mapping for the default servlet -- servlet-mapping servlet-namedefault/servlet-name url-pattern//url-pattern /servlet-mapping servlet-mapping servlet-namebizDispatcher/servlet-name url-pattern//url-pattern /servlet-mapping You have two mappings to the same url-pattern. Try that and see if it clears things up. On Sat, 2004-12-11 at 12:38, Ram Sriram wrote: I have edited the web.xml in conf directory.

I am debugging the servlet and the connected java application. When the gif is included in the page, the process displays the page and comes right back to my break-point in the java code. When I remove the gif, the page waits for a user to respond (the way one would expect Http to behave) and comes back to my code only when I click on one of the buttons on the page. I am taking this to mean the code of your servlet. yes. the java code the servlet is invoking. Is it possible that when you see the round trip, you are actually seeing the browser request for the image? It is possible. Actually, that is what is may be happening. How can I make the browser not come to the servlet but go and pick up the file from the directory. I am using only one servlet (a single URL) and I route the process through request attribute in the HTTP request. I have done that with JBoss in the past and it worked fine. In this application, I am not using any app server. I think there is a config in Apache to direct where the static resources are picked up from. I am not able to figure out where this configuration should be done for Tomcat. Or maybe it is not a configuration issue at all. As I do not run Apache, I am lost when it comes to it's config files.

One last comment, you asked about serving static content in Tomcat, understand that the static items in the app are served from the same place as the jsps or subfolders. If you want several apps to use a common source of static content, such as the images, this is a whole different matter. But for now lets put out one fire at a time.

Re: Display of Static Resources
Doug, attached is the web.xml. This is the one from the conf directory. I do not have (or not aware of) any mappings other than what is there in the web.xml. I have not configured any filters or valves Thanks...Ram Parsons Technical Services wrote: Ram, Post your web.xml. Only the active parts, leave out the factory comment sections.

Re: Display of Static Resources
Hello, Looks like you need to read an overview of how web based HTTP technology works. Essentially, in the typical and simple case, a request holding name/value pairs in a request object, HttpServletRequest in your case, and other information from the client makes a request and then your application either provides a static HTML page in the HttpServletResponse object or constructs an HTML page dynamically from an HttpServlet or a JSP page, which ultimately is a Servlet as well. Thus, a page never gets displayed and continues back to the servlet. The page only would return to the servlet if it has a refresh or something akin to that.

Re: Display of Static Resources
Hi Jack, Thanks for your response. I understand how HTTP technology works. I have a working application with a Form with form elements including a button. When I do not have a gif in the HTML, the behaviour is what is expected of HTTP. In other words, the displayed page waits for the user to enter data and click on a button that does (in my case) a Post and gets back to the Servlet. And when things work the way one would expect HTTP to work, I able to pick the Session Info, HttpServletRequest Name/ Value pairs including the button that was clicked on, and the attributes I put in the HttpSession when the servlet sent out the response (to survive the stateless session). All that is working just fine. The problem I am having is two folds: * One the gif doesn't get displayed. I have the gif in a directory image within ROOT. The properties on where the image should be displayed gives the correct location. So there is no problem with the HTML getting the correct location for the gif. * The other problem I have is, when I include the image (a gif, and I am having the same problem with a bmp, jpg etc.) the page doesn't wait for the user to respond, but makes the round trip back to the servlet. So even before the user clicks on the button, it comes right back. This problem goes away when I remove the gif from the page I hope I have stated the problem with a little more clarity this time around.
