Resource configuration problems on servlets (images, css, javascript)
Hi all, I'm a bit new to servlet programming so i'll be as clear as i can. I'm developing a small web application to test servlets in a project at school The project is fairly simple we a jsp pages that POST requests to a central servlet that controls the flow of the application My partner codded the jsp pages (which include css, javascript and images) everything working on his side as far as the pages displaying the images and the javascipt functionality The problem comes when we integrate to post the request to my controller The controller works fine but the resources are not working (css, images and javascript) the configuration is simple servlet servlet-namecontroller/servlet-name servlet-classorg.test.controller.Controller/servlet-class init-param param-namedebug/param-name param-value0/param-value /init-param init-param param-namelistings/param-name param-valuefalse/param-value /init-param load-on-startup1/load-on-startup /servlet servlet-mapping servlet-namecontroller/servlet-name url-pattern/controller/url-pattern /servlet-mapping the images have the right path to access the resources when i check the properties When i debug the application i can see multiple request when i acces the login page (or any other page for that matter) as if the request to get the images (or resources) were handled by my servlet and my servlet as it's coded does'nt recognize that type of event (each request has to have an event type) The controller works fine but even with multiple changes to my configuration i can't get the resources to work properly. Do i need to map the resource types to something so it bypasses my servlet (and not be treated as a request) I can't figure this out, though i've tried many setups.

Hi; Pascal Guy schrieb: The problem comes when we integrate to post the request to my controller The controller works fine but the resources are not working (css, images and javascript) I am not sure to understand your problem right, but: servlet-mapping servlet-namecontroller/servlet-name url-pattern/controller/url-pattern /servlet-mapping [...] Do i need to map the resource types to something so it bypasses my servlet (and not be treated as a request) There _will_ be a request for each and every static component (i.e. image, css, js file, whatever) to be loaded from the server - but indeed, you shouldn't have your controller taking care of that. How are you referring to images and js from within your code? You should be sure to use absolute URLS (i.e. /images/logo.png instead of images/logo.png), otherwise you might end up with your server searching for the content in a place where it's not supposed to be found (i.e. /servlet-context/controller/images/logo.png). If you keep that in mind, chances are you won't have to do much configuration work in your web.xml but simply ensure that folders containing static things are somewhere out of the way of your servlet mappings. Hope this helps, good luck to you! Cheers, Kris - To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Resource configuration problems on servlets (images, css, javascript)
Hi, i have tried the absolute path img border=0 src=/images/topImage.gif width=300 height=15 which renders to http://localhost:8080/images/topImage.gif (which i know is not the good path) but in the jsp we access the resource like this img border=0 src=%=request.getContextPath() + /images/topImage.gif% width=300 height=15 which renders to http://localhost:8080/TEST/images/topImage.gif(where TEST is my application) this worked fine for my partner on his sample controller servlet but did not have any server side code except the jsp also when i look at the deployed application in Eclipse it gives me this path C:\Program Files\eclipse\workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\_webapps\TEST\images_ so the path is good (i think) when i look at the properties of the images on the html page you said all the resources should make a request to the server but what i can't understand is why is it being caught and treated by my servlet that's why i assumed there was some configuration problem so these request would be treated by a default servlet of some sort and not my servlet which is configured to have event types for every request and treats these requests for resources as unknown events my lack of knowledge in servlets is probably misleading me here Pascal Kristian Rink wrote: Hi; Pascal Guy schrieb: The problem comes when we integrate to post the request to my controller The controller works fine but the resources are not working (css, images and javascript) I am not sure to understand your problem right, but: servlet-mapping servlet-namecontroller/servlet-name url-pattern/controller/url-pattern /servlet-mapping [...] Do i need to map the resource types to something so it bypasses my servlet (and not be treated as a request) There _will_ be a request for each and every static component (i.e. image, css, js file, whatever) to be loaded from the server - but indeed, you shouldn't have your controller taking care of that.
