Does anyone know of a sample distributed application (.NET or J2EE) using RMI or Web Services?
As often, Sun has an excellent tutorial on RMI:
http://java.sun.com/docs/books/tutorial/rmi/index.html
A RMI example: link
A Web Service example: link
Hope it helps
Here's a simple solution:
BEA Weblogic has a sample web application called MedRec that I've been using for a while. This sample comes with a .NET client built in called CSharpClient that connects to MedRec via Web Services. I was thrilled that I didn't need to install anything else.
In Weblogic 10 the client can be found in the folder "bea\wlserver_10.0\samples\server\medrec\src\clients\CSharpClient".
Another powerful bare bone working RMI example that loads dynamic objects from the client to server and execute it there then return the results. This can easily expanded for full featured distributed computing environment.

I am beginner java web developer, now my question is after i developed my application, how to make users see it on the web?
I used JSF,MySQL and GlassFish server in my development stage and now i want to publish it.
I got a domain name and an a web hosting account on goDaddy.com
In other words what to do after i develope my web application?
what steps should i take in server creation and other stuff?
I have searched alot but there is no specific way for it. I am trying to make this dynamic website based on jsf development--and it is already done--become alive and out their like any other web site?
any guide lines and steps should i take in making this steps ?
Either you will need a "Production" server to host the application yourself or use a hosting service of some kind that provides a Java EE container. If you're tied to Glassfish, you can Google for those providers like http://glassfishhosting.com/.
Other options that might be good fits for you are cloud services. Something like either Rackspace or Amazon EC2. Each has their own pricing tiers that scale based on usage. Good luck to you going Live!
Can host the code on Github and push it to Heroku.

I don't know the provider you chose but you need a java application server for your live environment. And optimally this should be the same server as your development server.
For our projects we buy a virtual server and install Glassfish on it. This costs around 15 € per month and we have the same environment for development and production.
Do I have been writing a java application, application is a console application.
Now, I want my application to listen to request at a port coming from web application and process those request and affect DB data.
I am not sure how to do it in a simple java project. Can I use some java webservices, and how?
Socket programming in Java is quite nice - a Socket is an abstraction that listens for data coming in on a single port from a single web address or server and can also send out.

Note that listening for data blocks program flow.
Most likely you're looking at learning Java Servlet programming. There are a lot of good resources to learn from.
However, from my experience something like Netty could serve you really well from both learning and actual application development perspectives. The site contains very reasonable example driven documentation, which takes user from non-blocking TCP/IP programming to HTTP support.
Yes , web service API (JAX-WS 2.0) is added to the Java SE 6. You can use these API to create a simple web service for the Java SE application.
See the section "Using JAX-WS 2.0 to Create a Simple Web Service" for the example .It shows how to create a standard web service end-point using JAX-WS 2.0 for the Java SE application.
Beside , this 5 minutes tutorial is very good at introducing JAX-WS .It includes the demo for implementing the web-service end-point and client and provide the eclipse project source code to download too. Please note that it misses the step to use wsgen to generate the service classes for the WebService end-point ,but it is not so difficult to figure out how to use wsgen
Hi guys is there a way to self-host a web service in Java just like WCF?
Jersey using Grizzly embedded within it would seem like a good fit for your needs. It wouldn't require and outside application server and would be fairly lightweight to get setup. You can just read the Jersey getting started documents to get going with that exact path:
Jersey User Guide
If by self-hosting you mean generating a web service endpoint for invocation, there are a number of ways to go on this, depending on your potential deployment environment.
I'd start off looking at Oracle's JAX-WS implementation, which includes RESTful capabilities. If you want to run a relatively simple stack, you could use Apache Axis2. And then JBoss has JBossWS, which can run standalone or in the JBoss Application Server. I'm pretty sure most of the major application server engines have a Web Services component as well.
I have two systems to integrate: 1)desktop application (Java6) and 2)web-application (HTML,JS). I want first application to share some services to the second one. How could simply I do that ? I want some simple solution.
Thanks!
Expose them as standards Web Services or RESTful web-services
For an application to serve services, it should start server socket on port and listening on it. Or it should be using webservices. JDK6 comes with WebServices support. May be you can look at it.
I have a web service that is using:
Java (familiar)
SOAP (new to me)
JBOSS (new to me)
The web service is currently unsecure. My task is to make it secure using https (ssl or tsl).
I am new to web services and web things in general. In the last week have gone through a tone of literature. Much of it which I think was not relevant to my project. I think that I need two things:
A pretty basic tutorial on web services (java specific)
A tutorial on making web services secured
Here are some of the tutorials I have gone through already:
SO Answer - In-process SOAP service server for Java
How to make a web service server.
Does not have instructions for the client.
Also does not specify what should happen so I am not certain that I got the propper result when navigating to the URL.
An Introductory Tutorial on Web Services, Java and XML
Pretty good description of lots of xml things and how messages are passed. Not certain but this seems more low level than what I need
Three Minutes to a Web Service
Good tutorial but in the second step one of the commands did not work.
I think that this may be because the tutorial is really old and maybe my jdk is differnt or something like that..
You can check out these frameworks
Apache axis
Apache cxf
The web service is currently unsecure. My task is to make it secure using https (ssl or tsl).
If it's just about (one-way) SSL, then this question doesn't have much to do with web services actually. It's more a web server or app server configuration issue. For JBoss, see SSLSetup or, if you are using Apache for the SSL encryption, see Apache SSL/TLS Encryption.
I would guess that you need to look at JBoss's documentation for how they handle security. Maybe this would help:
Chapter 8. Security on JBoss
