For a project, I have to convert a large Java application with an SWT GUI into a web application. Does anyone have any recommendations on starting a project like this? Some ideas I've had are:
Java Play
Java Server Pages
JWebSocket
PHP/Java bridge
Also, one of the problems is that I only have access to the JAR file for the application and need to run it with parameters from a terminal. Would this be possible from one of the options listed above?
I appreciate any help you can provide!
I have a standard java project working local made by another person i know.
It's about data retrieving.
I need to develop a web app supposed to do the same thing but accessible by anyone via browser.
I CAN'T edit the code for that purpose, at least some implementation details. A kind of black box.
Can you suggest me the best approach to make a webapp based on a local executable app through JSP & servlet ecc?
Maybe you can try something like webswing.
What is Webswing ? Webswing is a web server that allows to run any swing application inside your web browser using only pure HTML5.
The best days of swing framework are gone. Desktop applications lost
popularity and everything is forced to be online and mobile. But what
about existing application? Using applet technology proved to be
insecure, rewriting the application to web technology is too
expensive. This is where Webswing can help you. With Webswing, your
application is securely running on server and user's browser only
displays the application window. All this without changing single line
of source code.
I've made a dynamic web project in eclipse, and now I would like to put it on the web. Usually I'd just put the files on the web server, and it would run on my webpage, but this doesn't work when there's java involved.
Can anyone walk me through how to put a dynamic web project from eclipse on a real web server? I'm a complete newbie.
I've made a Swing .jar game which I want to run online. Is there any way in which I can make it run on the cloud, like on Azure? I made it into an applet, but its no fun. I know we can deploy Servlets on these clouds. How can I deploy this desktop application I made online?
Thanks in advance!
As far as I know, if you need to deploy an application in the cloud it has to be a web based application.
You Can use AJAXSWING to convert Java Desktop application(.jar) to Web Application(.war) automatically. Read the link ajaxswing
I am on a Java learning spree recently, however I am normally a .NET developer. (So please forgive my newbie questions.)
In .Net I can develop ASP.Net pages without using IIS, as it has a watered down web server (Cassini, I think it's called).
Does Java or a Java IDE have something similar so I can write and test JSP and Java Servlets without the need of a full-blown app server (Tomcat etc.)?
Also if there is one, does it work on Windows?
Tomcat actually isn't a fullblown appserver. It's just a servlet container (i.e. implementing only web component of the (indeed huge) Java EE API) It's only around 6MB big. Glassfish, JBossAS, Weblogic and Websphere as being full Java EE API implementations may be called as "fullblown appservers".
You can also consider Eclipse Jetty. It has a small footprint (download is only 2.2MB) and is useable as an embedded server and even runnable from a plain vanilla Java class.
As to IDE's, both Tomcat and Jetty are by default supported in "Eclipse for Java EE developers". You can easily integrate them in Servers view and then just associate your web project with it. Here's a nice video tutorial how to get started with servlet development with Eclipse and Tomcat.
As to working on Windows, Java is platform independent. You just need to have a platform-compatible JRE installed. Then any Java software will be able to run on the particular platform. Sun has a JRE for Windows --which is by the way also included in the JDK, if you already have one.
In the Java world the usual way to develop JSP based applications is to have a web container like Tomcat inside the IDE, and there are many ways to do it.
The easiest way to get started is to use Netbeans with a bundled web container - download the "Java" one from http://netbeans.org/downloads/index.html and install it.
After starting Netbeans 6.8, "File -> New project", choose "Java Web" to the left, and "Web application" to the right, and "Next". "Next". "Next". "Finish".
The editor now opens on "index.jsp" in a new project. Select "Debug -> Debug Main Project" and after a while a browser opens showing "index.jsp".
Switch back to Netbeans. Insert this line
<%= new java.util.Date() %>
just before the </body> end tag, and save with Ctrl-S (or "File -> Save").
Switch back to the browser. Reload the page. See the date shown. Repeat :)
That's it.
You can hook up your ant scripts to hot deploy to a local tomcat instance. That's the closest thing I can think of to the .NET development environment.
Eclipse can embed a dev version of Tomcat, and most other IDEs offer a dev server too, I should think.
But also I should also point out that obtaining & setting up Tomcat is quite a bit simpler than setting up IIS. Just download a zip file and unzip -- poof! you're done!
When I was playing with JSP a while back I used NetBeans which has a Web & Java EE-installer, that
Provides tools for developing Java SE,
Java EE, and web applications. This
download option also includes the
GlassFish V2 UR2 application server
and Apache Tomcat software.
Try Jetty http://jetty.codehaus.org/jetty/
Jetty is an Open Source HTTP Servlet Server written in 100% Java. It is designed to be light weight, high performance, embeddable, extensible and flexible, thus making it an ideal platform for serving dynamic HTTP requests from any Java application.
