using embedded jetty to create a web interface

Question

I am a newbie at web development, and at using embedded jetty. The source code presented below is developed using eclipse IDE. I have to start the jetty server programmtically, I do not have an option of starting it via the command line. It needs to be an extremely light weight web interface as it will be launched from a system with low memory/processing speed. I have developed the following directory structure in ECLIPSE ``` JettyExample <Project> src sample_package HelloWorld.java WEB-INF index.html web.xml ``` The source code of HelloWorld.java ``` public static void main(String[] args) throws Exception { Server server = new Server(8080); ResourceHandler resource_handler = new ResourceHandler(); resource_handler.setDirectoriesListed(true); resource_handler.setResourceBase(args.length == 2?args[1]:"."); resource_handler.setWelcomeFiles(new String[]{ "WEB-INF/index.html" }); System.out.println("serving " + resource_handler.getBaseResource()); HandlerList handlers = new HandlerList();…

Accepted Answer

You've set your welcome file to WEB-INF/index.html. Items that are located inside the WEB-INF folder are only visible to the servlet container and are not accessible outside of the container. This will not work, since index.html is hidden behind WEB-INF. Additionally, when working with WEB-INF, it's customary to access it from the root of the application, such as /WEB-INF/file.html: ``` resource_handler.setWelcomeFiles(new String[]{ "WEB-INF/index.html" }); ``` If you include just the index.html file as a welcome file, and also make sure index.html is in the root of your application, the Jetty Server should be able to find it: ``` resource_handler.setWelcomeFiles(new String[]{ "index.html" }); ``` Be sure to restart Jetty after making this change, since the application will need to reload this information. Also, when configuring a new Web application on a server, it's generally a good idea to turn your logging levels all the way up. The server and frameworks typically log at lower levels so they don't interfere with application logs; however, in this case, you need to see what resources the servlet container is trying to access when you load localhost:8080 in your browser. To clarify further, the ResourceHandler.setWelcomeFiles Java method is the same as configuring the server via web.xml in non-embedded Jetty, using the following XML entry: ```

index.html

``` There are some examples and more documentation at the Eclipse Wiki Page on Embedding Jetty, be sure to check them out for more guidance. File structure of embedded Jetty 6: Here is an example file structure of a copy of embedded Jetty that I have. Note that the index.html is in the root, right next to src: ``` build.properties* index.html* README.textile* src/ war/ build.xml* licenses/ server/ test/ WEB-INF/ ```
