I have completed my Java web application and trying to deploy to the web host for hosting. But how do I 'compile everything'? I tried to build the project and landed with the following files.
projectname.properties, projectbname.iml, projectname.xml,
module_projectname.xml
Do I just place them on the public hosted folder and its done? Or is there any guide. I keep coming across guides which assumes I know how to build. None seems to elaborate how to actually build and what files I need for hosting.
I am familiar with a website and where to place the html/css/js files. But this being a Java web app with all sorts of files, its confusing me. Please help.

I would suggest use heroku to deploy your web app. Heroku is very simple cloud based hosting quite useful for beginners and is easy to start with.
First read Getting Started with Java on Heroku carefully and then
follow the below instruction to deploy your app.
Deploying from IntelliJ IDEA
i have searched for various solutions in need of creating a simple java class with a deploy method. This deploy method should get the path of the war file and deploy it in app engine google account. i tried to get the jars of it and use these methods.. but i didnt had any details for help even after searching. so any good suggestions? on how to deploy it directly in google app engine
You mean programmatically deploy to GAE?
Sure, it's possible. Take a look at AppCfg source and extract classes relevant to deploy.
I just created a new project with NetBeans using the database template to connect to a MySQL database. After searching a while I got a question and hope anyone can help me with that:
I want to create a dialog in my application to change the connection-informations to the MySQL Server. I realized that the template gets the infos out of the persistence.xml file when it compiles. But I cant find the point in the source code where he reads the xml file and gets the informations. Is there any way to hardcode the IP adress and the Database name and so on in the code?
Thanks for your help!
Don't use the Swing Application Framework.
Newer NetBeans IDEs will display this disclaimer if you create a JavaDesktopApplication project:
Note that JSR-296 (Swing Application Framework) is no longer developed and will not become part of the official Java Development Kit as was originally planned. You can still use the Swing Application Framework library as it is, but no further development is expected.
If you are looking for a Swing-based application framework, consider using the NetBeans Platform [platform.netbeans.org][1], which is a full-featured platform suitable for creating complex and scalable desktop applications. The Platform contains APIs that simplify the handling of windows, actions, files, and many other typical application elements.
As to your question regarding the persistance.xml file, that's read somewhere in the framework (probably in org.jdesktop.application.Application). It's not in any of the files in your project. All you can really do is change the values in the file.
I'm new to IBM Rational Application Developer. I'm running RAD 7.5.5 and want to use GWT as the front end for an application I'm writing. What I'm asking is basically if someone has had experience with this, and if so, explain in a few simple steps how it's done or maybe refer me to an example somewhere online where this is explained.
Deploying to WebSphere is no different then deploying to any other Application Server, or even a servlet container. You just need to compile your GWT app and package it in a WAR/EAR file. You deploy the application and have whatever HTML file you want the GWT app to appear in, include the nocache.js.
If you generate your app either using the command line script, through Eclipse, or with Maven, this HTML file will be generated for you. GWT is server agnostic, unless you want to use GWT-RPC, in which case you need a Java backend. You could run GWT on a plain Apache server if you wanted.
so now i think i have learned all basics and terminology for java. but what i don´t know is how to code and display a web page with Netbeans in Java.
the most tutorials contains lots of talks about different technologies "Java uses Java Beans, JSP and servlets" and so on. Where can i find short practical tutorials that actually teach me where to code what and then compile and where to put all the files (war, jar, ear..) in Glassfish to be able to see the output from a Web browser. Simples things that makes one understand all these different "layers" which are just classes using classes. Feels like i never get to know how i can put up a web server with Java cause I can´t find this kind of tutorials.
Would be great if someone could send some links to such practical stuff.
Thanks.

How do I code and display a web page with NetBeans in Java?
Let's go! Fire up NetBeans. I'm using NetBeans 6.7.1 with the Java EE stuff installed, and I've got a GlassFish installed and tied up, so I don't have to care about that stuff. Your setup might differ in the details.
Do a File->New Project, and pick "Java Web" from the categories. Select "Web Application" and hit Next. Enter a project name and tweak the location, if liked. Hit Next. The next page should have a server selection drop-down; as hinted above, mine has "GlassFIsh v2.1" selected. That's fine - as long as NetBeans can interact with a Java application server of some sort, this crash course will run okay.
Make a note of the "context path" - this will be based on the project name, and basically forms the base of the URL at which your application will reside. Hit Next. Ignore the next page, for now, which talks about various frameworks, and hit Finish.
Churn, churn. You should eventually see your web project created. It's a very simple application which contains a single JSP file, and that will be open in the main editor. It's got a bunch of HTML in it, and some JSP syntax.
Take a look at the project structure. You've got a "web pages" folder which contains a WEB-INF directory, and an index.jsp file. That's the same file you're looking at. WEB-INF is a standard directory which contains the metadata used to deploy your application, and also the compiled classes that power it.
The only thing you should need to do now, in order to get to the original objective, is to hit the big ol' Run button, or right-click on the project and select "Run" from the menu. NetBeans will compile, and then fire up your application server and deploy the application to it. Finally, your web browser should pop open a new tab with the classic "Hello, world" page in it.
At this point, what do you actually have? You've got an empty web project with a single JSP file in it. You could customise it, but that's maybe not very exciting. What you're really looking at is a basic framework in which you can apply your learning of JSP and of servlets as you get to grips with them.
How to proceed with said knowledge transfer? I recommend a decent book or two. The one I used to get going was "Beginning JSP, JSF and Tomcat Web Development: From Novice to Professional" (Zambon, Guilio; Apress; ISBN 1-59059-904-7), which has a decent beginner's guide to how JSP and servlets work together, and a handy reference guide for the former.
As soon as possible, you're going to want to migrate away from raw servlets and JSP to tying them together in a slightly more flexible way using one of the frameworks I skipped over earlier. I'm not going to tell you which one to learn; there are several pretty decent ones. Try Spring MVC, or Struts. Once again, I'd suggest getting a decent book.
I would start by taking a look at servlets and JSP. I found this book helpful when I read it: Head First Servlets and JSP
Netbeans comes with many sample projects, create a few and browse the source code.
A already working sample is always a good starting-point for your coding.
If you're also interested in using Eclipse, which makes it very simple to create and deploy web applications here's a nice tutorial - WTP Tutorials
Hi to start code and setting up web server with java follow the following procedure.
First you need to install Apache-Tomcat or Jetty any web container or servlet container.
And you have set the classpath of servlet-api.jar file.
Next you will have to save your web-page code stuff in web-apps folder of tomcat.In web-apps folder there you have to create a web-inf folder in which web.xml file is stored.And after writing servlet and jsp programs the compiled class files are stored in classes folder of web-inf folder.JSP files are stored along with WEB-INF folder.
You have to keep all the jar files in LIB folder of classes folder.
The web container will take care of initalizing servlet, loading class using inti method.Using service method it will create two objects request and response.
The Java EE stack is quite a mouthful. I suggest you just look at writing a Web Application (WAR), and deploy it to Tomcat.
Unfortunately doing a full WAR-file deployment is rather tedious so you generally want some help from your IDE or the web container.
The easiest place to start is probably installing and starting Tomcat and then fiddle with the files in the file system. There is an example application.
