Serving static content with jetty 7, using defaultservlet configured from web.xml - jetty

This is jetty 7 and xml configured, not embedded.
I'm trying to serve a static file, crossdomain.xml, to an app that connects to a datasource I run from jetty. To do this, I configured a servlet and its mapping thus:
<servlet>
<servlet-name>default </servlet-name>
<servlet-class>org.eclipse.jetty.servlet.DefaultServlet </servlet-class>
<init-param>
<param-name>resourceBase </param-name>
<param-value>/foo/foo </param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>default </servlet-name>
<url-pattern>/* </url-pattern>
</servlet-mapping>
Sadly all I get are 404's. Any help would be much appreciated, btw the rest of my web.xm lfile looks like:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"version="2.5">
<servlet>
<servlet-name>cometd </servlet-name>
<servlet-class>org.cometd.server.continuation.ContinuationCometdServlet </servlet-class>
<load-on-startup>1 </load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>cometd </servlet-name>
<url-pattern>/cometd/* </url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>default </servlet-name>
<servlet-class>org.eclipse.jetty.servlet.DefaultServlet </servlet-class>
<init-param>
<param-name>resourceBase </param-name>
<param-value>/foo/foo </param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>default </servlet-name>
<url-pattern>/* </url-pattern>
</servlet-mapping>
<servlet>
<servlet-name>initializer </servlet-name>
<servlet-class>com.foo.research.Initializer </servlet-class>
<load-on-startup>2 </load-on-startup>
</servlet>
<filter>
<filter-name>cross-origin </filter-name>
<filter-class>org.eclipse.jetty.servlets.CrossOriginFilter </filter-class>
</filter>
<filter-mapping>
<filter-name>cross-origin </filter-name>
<url-pattern>/cometd/* </url-pattern>
</filter-mapping>
</web-app>

I had the same issue; here is a snippet that works (Jetty 6.1.22).
I basically replaced org.eclipse with org.mortbay and removed the
resourceBase parameter (but see below). And this actually ends up in my web.xml file inside my WAR file:
<servlet>
<servlet-name>myservlet</servlet-name>
<servlet-class>foo.bar.MyServlet</servlet-class>
<display-name></display-name>
<description>The smallest Servlet ever!</description>
</servlet>
<servlet>
<servlet-name>default</servlet-name>
<servlet-class>org.mortbay.jetty.servlet.DefaultServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>myservlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>default</servlet-name>
<url-pattern>/static/*</url-pattern>
</servlet-mapping>
Then, you have to put your static files in the "static" directory in your
WAR file. Like this (just to make it clear):
ROOT.war
|_ WEB-INF/
|_ static/
If you want to put your static files elsewhere (but still map them under
the /static/ URI), you can use the resourceBase parameter to specify the
directory, just like you did.
Jetty's documentation helped me to understand this a little bit better:

Building a REST web service

I am trying to build a simple Web service.
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

</servlet>
<servlet-mapping>
<servlet-name>Jersey</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
This is my class:
package com.service.user;
import javax.ws.rs.*;
#Path("/user/service")
public class UserService
{
#PUT
#Path("/create")
public void createUser(){
}
#GET
public void getUser(){
System.out.println("Inside GET");
}
}
I am running it using this request: http://localhost:8080/REST_service/
And it starts fine. But when I go to call the GET request, it doesnt get called.
http://localhost:8080/REST_service/rest/user/service
I am very confused as to what's going wrong and not able to debug.
Any help appreciated!
You still need to tell jersey to scan your packages for your resource classes so it can register them.
<servlet>
<servlet-name>Jersey</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>jersey.config.server.provider.packages</param-name>
<param-value>
com.service
</param-value>
</init-param>

Static resources not accessible in Jersey rest

I am having problem accessing my static resources in /project/resources/(css|js)/. I was able to access index.css in my css folder, but no other. I tried to find the root cause, changed regex expressions and messed up everything. Now I am not able to access even index.css now. Please find details below -
File structure -
webapp

| |____ css
| |____ js

I tried to find solutions on net but nothing was useful. Hoping for the useful solution.
Thanks in advance.
The jersey.config.servlet.filter.staticContentRegex property should work if you are using Jersey 2.x.
I believe your static resources are only on resources folder.
Try this:
<init-param>
<param-name>jersey.config.servlet.filter.staticContentRegex</param-name>
<param-value>/resources/(css|js)/.*</param-value>
</init-param>

Deploying java web application with javadoc as welcome-file

I have created java web application. When i deploy my applicaton to server using tomcat7, i want to deploy my javadoc as welcome-file so when i go to root directory of app i want to see reference. But instead tomcate gives lots of 404 error. Here is my project structure;
And my web.xml is;
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

</welcome-file-list>
</web-app>
How can i fix this?
nevermind. I solved the problem by moving javadoc contents to "Web Pages" directory. And in the web.xml file i changed javadoc/index.html with index.htmland deployed it. It works.

How to the Change URL Patern so that it can access normal JSP also

This is my web.xml for my webservices developed using Apache CXF project
As a result of this url pattern , even if i want to access a small HTMl page using
http:localhost:8080/ZTWeb/Test.html
This si result in No Service Found ( As i guess each and every request is being treated as Web service itself )
Please tell me how to resolve this , Means how can i access the HTML pages . JSP pages inside the web application
<web-app>
<servlet>
<display-name>CXF Servlet</display-name>
<servlet-name>CXFServlet</servlet-name>
<servlet-class>
org.apache.cxf.transport.servlet.CXFServlet
</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>CXFServlet</servlet-name>
<url-pattern>*</url-pattern>
</servlet-mapping>
</web-app>
Map the CXF Servlet to another location, for example /services/*

Is it a REST web service?

I am working on a legacy application which have a .war with following structure (and I want to add my servlet in this war)
myApp.war
- axis2-web (Downloaded from http://ws.apache.org/axis2/download/1_1/download.cgi)
- META-INF
-- MANIFEST.MF
- WEB-INF
-- classes (But it don't have any `.class` file , it have `log4j.properties` file)
-- conf (Contains `axis2.xml`)
-- lib (contains many jars)
-- modules
-- services (Some `.aar` files)
-- web.xml

Is it a REST web service ? I Googled and found some tutorials on REST which says REST services have services.xml file but I couldn't find it in my application. I want to integrate my servlet in above war so what will be the right way to do it ?
PS: Please let me know if I am missing anything.
As I understand RESTFUL WS approach that the it has a traditional http request and response with get ,post ,put or delete operations directly passed to the web service and so the response doesn't have any special format (JSON-RPC,SOAP) .
For example , if we write simple code some-service.jsp and put this code on our server
the restful tells us to call the service using any http client passing it the required params
and then we will get the service response .
Now if your application meets this , it would be RESTful .
Note : there are no any specific implementation techniques for REST it is just a WS approach
hope this would help you
