I have always programmed my applications in php. But recenlty I discovered that best combination of language and server to achieve scalable comet functionality is Java + Jetty, because jetty support continuation, which eases the number of threads in the server. However, I'm slowly learning Java right now. I'm using Eclipse as my IDE with the plugin RSE(Remote System Explorer). When I used to program in PHP I just created a new php-file inside of htdocs in my Apache webserver, very simple to deploy. But now when I program in Java I have to compile the file too. Another flaw is that I cant create a Dynamic web project in RSE, so to deploy a webapp I have to drag all my file in my personal computer to my remote server and unzip and compile(manually via ssh). How do you guys deploy your java webapp in Eclipse?
And yes I haven't found any good answer to this on the web yet before asking this question.
Install a web server on your machine, and do all your development and tests locally on your machine. When the application is ready, deploy it on your remote server.
You don't have to compile it on the server. Java bytecode is portable across OSes and machines. You can build your war file on your machine and send it to the remote server.

Are there any easy way to run a java code from the IDE (Intellij for example) on a remote machine (without jar)?
I am trying to execute the code that I am developing in a remote machine, without package and upload a JAR every time that i compiled the code. The idea would be to run the code on a remote machine in a simple way and see the result in the IDE.
Summary:
The main idera is execute the program as a normal script in another machine and be trasparent to developer. Execution looks normal but the code are being executed on another machine.
This is an exploratory question because im not find any similar solution.
Without having a better idea of the big picture, I'd say that this may not be something that IDEs are likely to make easy for you.
There are possibilities:
Most IDEs support plugins and custom tool integration. You could set up automation to transfer the files and invoke them remotely. You'd basically be doing all the work.
You could use something like a remote disk mount or an editor with remote file editing support to store the files on the remote server and then modify them locally and run them remotely using a remote shell.
You could use some sort of cloud IDE setup that would allow you to edit the files that are hosted on the remote server and invoke them. Tools like this exist, although you'd have to install things and it might be more work than the other options here.
If the remote server is a web application server (e.g. Tomcat), you could certainly have your IDE deploy a WAR to the remote server and then invoke it over HTTP.
I have developed an android application and i need to set a server for sending and receiving data from clients. The server must also be able to run python script for data mining.I want to code the server in java(for analysing the data obtained from mining and handling the client requests).
what will be the way to set the server for my purpose. I have read that servers can be set up in eclipse or installing apache in linux in a virtual machine. will anyone of them fit my need or is there any other better alternative.
Well, it depends on your needs. If you want to run Python scripts from Java, I don't really see why you would code your server-side logic in Java and then use Python data-mining scripts (you might have some problems with execution of Python scripts through Java and server setup). I know that Python is much better in data-mining, so stick with it. Consider Python for server-side logic. In case you want to run data-mining script manually that doesn't really mater, so you can separate the languages.
In case you want to separate it into two languages, then you must install an application server for Java. There are plenty of options for that, even open-sourced (Wildfly, Glassfish, ...):

You can set most of them in Eclipse for development, for production releases they can be installed either on Unix or Windows. The Apache option you mentioned is probably Apache Tomcat application server. You can read more about Java application server set-up in Eclipse:
http://www.eclipse.org/webtools/community/education/web/t320/Configuring_an_Application_Server_in_Eclipse.pdf
Depending upon the requirement, you can setup the server in many ways in any operating system like linux (fedora, ubuntu), windows, mac osx etc. There are many java web frameworks to follow to make your own server and provide API for mobile.
These are some java web frameworks:
playframework
Spring MVC
Grails
You can setup above and other frameworks and can setup in any enviorment. For initial, you can setup in your local system, then later you can upload into your remote server.
For setup, please see the respective framework's documentation.
It would be wise to choose json for communication between mobile and server. You can consume the API in android using default HttpURLConnection or you can follow other opensource http connection library like retrofit, asynchttp etc.
I understand the concept of source version control and how it applies to self-contained projects like a Windows application. But for web development, most files are stored on the web server. This has become a headache for development with many people just copying and renaming files and then pushing files over to production is another mess.
I need some kind of source version control that is relatively not too difficult to learn and must be GUI-based or have a GUI as an option. The people who will use this have little or no knowledge of the command line.
How can I integrate source version control with web server files? What software is available for such an endeavor? And is it possible to have the source version control software administer both the production and development web servers or I may only have two separate source version control installs for each web server and manually push over changes?
The web servers are Windows-based and also use Tomcat for Java/JSP.
Any help would be appreciated. Thank you.
I think you are not clear on the idea of version control. Version control is about managing your code. It is about putting your code in a remote server (may be in a central location) and accessing it using a client tool. This way a number of people can work on different part of the code and than push their work to version control server. It has nothing do with the type of the project.
The project can be a windows application, web server application or any application.
While using version control, in regular intervals or whenever needed you build your code from the version control server and deploy it to the web server which means you are deploying code that is already build (a .war for a web application).
You first deploy to your development server and later deploy the same war to the production server.
You can use SVN server for your version control server and Tortoise SVN as client.
You have to split in mind two different but interacting things - Version Control and Deploy Tools:
VCS has to do with any evolving over time items, which you want to have under control
Deploy just deliver correct object into the correct place at the correct time and convert "set of something" into Product.
Deploy isn't a problem per se (almost any job can be automated), main problem in multiDEV environment (2+) with central STAGE (less with PROD) server is question of communication between Devs and synchronizing of their operations, i.e. - workflow and management:
just imagine 2 (or more) devs, performing diferent unrelated tasks, which want to test latest own (and only own) changes on common STAGING server (because they haven't functional local environment). If 1-st deploy "some WIP" on server, he don't want to have own tests be interrupted and code poisoned by deploying third-party changes. They must to communicate and coordinate actions, it can't be dumb "copy to..." in post-commit hook
And is it possible to have the source version control software administer both the production and development web servers
Yes. But VCS does not "administer" web-servers in common sense, rather it's "communicates" or "take into account"
I use Eclipse "Dynamic Web Project" to create and test web application. It will publish my application on application server in convenient way. I don't need to write script, just wizard.
However, I am wondering it is a decent way to deploy a web application. What's your opinion? Thanks!
(I used to use Ant script to deploy my application, it's standard way.)
plus: Dynamic Web Project uses its specific directory layout which is different with Maven standard directory layout.
This is fine for deploying to a dev or test server. Its a convenient way to quickly deploy to have a look at changes you've made and to do tests.
I would definitely not allow this for any other environment, eg live, pre-production etc. You should have an established process (eg documented change control) to deploy to these environments.
I have heard it's still recommended to cold deploy and restart the server for not having a trouble with memory leaks, dynamic class loaders. For myself I think comfortable to deploy from Eclipse to most environments. Basically Eclipse WTP server adapter can run the same deploy command as the other processes. When I use clouds like GAE or Beanstalk I do deploy from Eclipse plugin, it is the same like command line.
This might be a newbie question. But I am working with iPhone programming and I have hosted my own webservices written in Java on a ubuntu linux and Eclipse EE edition with a glashfish server. Is there any easy way to export this webservice and getting it hosted elsewhere.
I have been looking around for a solution but have not found the grail yet.
All help is appreciated
I don't know what you have in mind when you think "export", but you're deploying a WAR file locally on Glassfish. That's the package you need to pick up and move to your hosting service. They, in turn, have to accept WAR files and deploy on a Java EE app server.
Your WAR file should be portable if it has everything your app needs. Make clear what you need from the server (e.g. dependent JARs); everything else should be in your WAR.
If you can adapt your solution to the limitations of the Google Application Engine, they will host it for free.
This strongly depends on how many Java EE features you use.

You just need to take war file and deploy it somewhere else you want
