How do I run a HTTP proxy server?

Is there a tutorial for this?

Do I need to have root priviledges on my system (ubuntu)? You don't need to run it as root. If you are using linux, then. is an excellent free web based solution for any task. You may want to make a backup of your machine and test it before installing. Otherwise, the setup process should be as simple as

How to create a Web service proxy in Java?

I need to create an interface that allows clients to send a request and receive a response via my java Web service.

The client needs to know the location of the service. The service should return the data in xml format.

How should I go about creating this service? And how to make it work on Windows and Linux machines without having to have two different services? Your questions are too broad to answer here. Here's some pointers: For starters you may want to read up on Java's JAX-WS API. You can deploy your web service as a J2EE application and use the @WebService annotation. You can also deploy it on top of a Web server. If you want to target multiple platforms (ie you want clients that use Java one side, and clients that use .Net on the other), then you'll want to take a look at Sun's App Server product.

Also, just to add to the above: you don't have to do all these separately. You can use the Jersey framework to implement a servlet container - and use it for multiple purposes.

Here's one possible way: First of all, here's how to host an .ear archive in Glassfish, assuming you're running it in Tomcat: Glassfish v3 / Glassfish AS v3. Install/configure the Apache Aries Servlet Container (AS). Download Java WebSocket API from Maven central. Add following dependencies in pom.xml . org.apache.aries
org.proxy 1.0
. com.sun.ws
jaxws-ri. 2.10 You have two options for your webservice - AS and Jersey, the latter being the current de-facto standard for the Java Web Service API.

How to create an HTTP proxy server in Java?

I'm new to this concept of HTTP proxy servers.

What is the basic functionality of a HTTP proxy server and what can you do with it? Please help me how to implement an HTTP proxy server in Java? Thanks! The simplest way to perform an HTTP proxy in Java is using standard HTTP client libraries. I recommend Apache's HttpClient. The most basic way to implement an HTTP proxy is:

Create a ServerSocket on a specific port. Start an ServerSocketConnector to listen on the port and a SocketChannelConnector to connect incoming requests to the socket. From the SocketChannelConnector you have the choice of handling requests with a simple socket client or with an HTTP client that is able to parse a HTTP request line (method, URI, etc.
