I want to deploy my Java EE project to the client desktop (Not, to a domain). How may I able to achieve that without again installing Servlet containers like Tomcat.
I want to make my war file as clickable file, to what ever system I deploy it to.
Hot to achieve it? I mean is there any way to deploy war file + servlet containers as a single file, as the web app can be opened any where without installing Tomcat or GlassFish etc., I use NetBeans IDE.
Check out Excelsior JET: it can compile your war and servlet container into a native executable for a given platform.

I built my java RESTful application in Eclipse with Jersey and a couple other libraries. My question is, how do I deploy this to a Tomcat server? Do I export it as a WAR file? Do I need to deploy the libraries I used as well or are they packaged in the WAR file?
The server is running on an ubuntu machine which I can access over ssh. I got the server running with "apt-get install tomcat7". Which folder should I put it in? Is any configuration needed? What should I do with the web.xml file?
Thanks in advance.
You usually wouldn't use Apache to directly serve a Jersey web application as Apache is not a Java application server. It would be served from a Java server such as Tomcat instead. If you wish to serve your Jersey application as if it was located on your Apache server, you would still have a Tomcat server running and set up a reverse proxy to your Tomcat server. I personally use a server such as Wildfly or TomEE which implements the full JavaEE profile and means you are less likely to run into errors. Nearly all Java application servers also have the capability of serving static content so unless you specifically need Apache features, you do not need to go to the trouble of also running Apache.
With each one of these servers you would need the .WAR file and deploy it, either through the appropriate maven plugin, the web manager or placing the .WAR into the appropriate directory.
Dependencies for a .WAR specified in the 'compile' scope will be included as part of the .WAR file and those in the 'provided' scope will not be included (for when your web server has these included)
I have created an application in Java EE, I have learned how to deploy it in the tomcat server using the manager app or by copying the war file to the webapps folder. Now I can start the tomcat server only from the Netbeans IDE.
I want to know how to start the apache tomcat server without using the IDE and run my web application from the war file deployed. If I'm headed in the wrong direction please correct me. I'm asking this to gain knowledge of how to deploy the .war file in another server system without using the IDE only the tomcat server.
The shell scripts located in "CATALINA_HOME/bin" are the most bare-bones way of getting Tomcat up and running. The two scripts capable of starting Tomcat in this directory are named "catalina" and "startup", with extensions that vary by platform.
In your tomcat installation directory, there would be a startup.bat/sh file which will start the server for you. Moreover you can see the conf folder as well if you want to change any configurations. Whatever war you copy to the webapps folder will be automatically deployed
I have developed a dynamic web project using eclipse and i am having a domain name and a web hoster. all i want to do is to upload my eclipse project to my web hosting site. Currently i am using html 5 template on my website but i want to upload my own project on it. I have heard that we can do it by using war file but i am not sure how to do it as my html 5 template contains many html page like index.html and it is more in size as compare to war file which i have exported. Please tell me i am totally clueless about it
Your web host needs to support Java and some Servlet container. If they don't already have those two things installed, you'll need to install them yourself. Once that is done, in Eclipse, you will need to export your project in the form of a .war file and place it in the appropriate folder of your Servlet Container. For example, with Tomcat, you would place it in its /webapps directory. You then start your Servlet Container. Your web application will be up and running.
If your web project includes Java web technologies such as Servlets and JSP, you will need to
Build your war file first either with Ant, or Maven.
Then you can upload the war file to your web server using some type of deployment tool that is usually available on the hosting web server. For Apache Tomcat for example, you can use the Tomcat Manager tool to deploy your war file.
I guess a drawback of using such an awesome IDE like eclipse is that you miss the point for what happens behind the scenes of an application. I'm a ruby developer so not a java veteran. So I've been coding a project in java and using the spring framework for IOC and MVC. Can someone explain to me what is going on when I select run on server in eclipse? Because eventually I will be deploying this masterpiece of an application to a Linux server. Here is my setup. I am using Spring MVC 3 and the maven plugin in eclipse. In the pom.xml file, I have stuff like latest spring release version, log4j, spring mvc, spring context etc.
I have been testing my application on localhost using the handy option of run on server in the eclipse IDE. The server configuration in eclipse is pointing to the tomcat directory location for where I have installed tomcat 7. Please demystify what happens behind the scenes and what I will need to do if I want to deploy this application on a production server. The more detail the better. Thanks a ton in advance.
Deploying a web application to Tomcat is as simple as this (assuming Tomcat is installed)
Bundle your application in a .war with the correct format.
Move the generated .war file to the /webapps directory of your Tomcat installation folder.
Run the /bin/startup.[sh|bat] script in the Tomcat installation folder.
Note that there are intermediate steps you can do to configure the deployment, like changing your context path. Go through the Tomcat documentation for details.
In step 3, Tomcat will extract the .war contents to a directory in the /webapps folder with the same name as your .war file. It will use this as the context path. The script itself launches a java process by putting the WEB-INF/[class|lib|...] onto the classpath along with some Tomcat libraries.
So Eclipse basically does all the steps above for you.
Ultimately you are deploying an web application that means you are deploying a war file to the server. Regardless of using frameworks like spring, struts anything.
SO a web application request starts from web.xml file. SO for spring mvc application, you are mapping all request coming from browser to DispatcherServlet and then this guy is responsible to manage whole life cycle of your application.
For more details of how MVC works please see
http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html
So in order to deploy your application (a war) on server first of all you have to create a war from your source code. You can go to traditional approach to use java given utility like using jar from command prompt or you can use ANT, GRADLE, MAVEN and such build tool that creates war for you in automated way.
Spring is not doing anything extra for you. I believe you to research a bit more on how these tools works.
Once a war is ready for you, you can simply go to tomcat UI and there you will find options to deploy your war.
I hope it helps you.
All the majic happens in two places.
The first is your 'Servers' directory in the root of your Eclipse Package Explorer. These are your server configuration files that Eclipse will use (mostly) when it creates a new server instance.
The second is in the ./metadata/.plugins/org.eclipse.wst.server.core/ file system directory in your Eclipse workspace. This is where the tomcat application is actually deployed by eclipse.
The Tomcat Documentation is pretty good actually and helps explain how to do deployments. FYI, I do not know many people that use the Manager, from my experience most people deploy their applications by hand.
(Tomcat version 5.5, in case it matters.)
I have a library in one of my web applications that needs to be configured with a machine-specific license before use. I don't want to put this library in shared/lib because at some point I may want to run multiple web applications with different versions of the library.
Right now the .jar files are stored in WEB-INF/lib. Thus, when I build the .war file and upload it to the server, the .jar file would still be the one bound to my PC. I would like to put a bash script somewhere in the webapp that Tomcat would automatically run when deploying the .war file - this script would then run the configuration script and bind the server's license file to the .jar. Is this possible? Is there a nicer way of doing what I want?
You could create a ServletContextListener to do that in the contextInitialized() method. And from that listener you can run the "configuration script" directly, no other script required.
