Java SE

This category will hold articles for Java SE and Eclipse.

I think Java can be a lot of fun, since it already delivers a lot out of the box.

People who develop Java APIs usually give it a lot of thinking and work.

 

Java EE in comparison to Java SE can be described as a huge collection of Frameworks and API developed around Java SE.

Java EE is not a stand-alone programming language, but based on Java SE.

Encoding an URL should be a very simple task. First time I encountered this I did not expect having to do an online research to find an article showing how to do it without using deprecated classes like URLEncoder.

Anyhow. Below a solution that works for me.

	@Test
	public void testUriEncoding() throws URISyntaxException,
			MalformedURLException {
		final String add = "http://www.huhu.com/{ähm}";
		URL url = new URL(add);
 
		URI uri = new URI(url.getProtocol(), url.getHost(), url.getPath(),
				url.getQuery(), null);
 
		System.out.println(uri.toASCIIString());

In order to change the background of a JavaFX Scene object you have to change a CSS file, which is programmatically associated with corresponding Scene.

In below example the background is set to an image, which is placed in the same directory as the CSS file. I do not think this advisable in a real project where you would have it in a bin directory, but for example purposes it is ok.

.root {
-fx-background-image:url("background.jpg");
}

The CSS file is set in the Scene object as follows.

scene.getStylesheets().add(getClass().getResource("application.css").toExternalForm());

The result looks quite nice, but I guess that depends on the picture as well ;0).

 

If you have to present users with a JTable for editing properties in an application, the following source code might be of interest for you.

The below code also supports updates to a Properties object through this TableModel.

This category provides articles regarding JavaFX as well as e(fx)clipse as this seems to be a good start to deal with JavaFX.

JavaFX has been around for some time now and Oracle is currently triying to enforce it as new standard for Java Rich Client Applications.

Regarding to a developer I know it has had some improvements over the years and it looks like it is going to be a try out worthy successor of AWT (Java), Swing (Java) and SWT (IBM).

However Oracle is trying to push this somewhat new technology into the market for some time now, it has not yet been accepted by the Java community.

Root cause for this seem to be the following reasons.

  • Companies are not asking for Rich Client Applications, but there is a trend for developing Web Applications. Therefore motivation to use anything like AWT, Swing, SWT or JavaFX is low except for private purposes. However JavaFX supports Mobile Applications, which is a big market. Since integration with mobiles is asked by companies as well for web applications and older technologies not supporting it, I can understand Oracle not wanting to provide support for it anymore.
  • Programmers are lazy. If you give them something completely new to learn, it takes quite an effort to get to a stage where you are as fast as using already known technologies. The standard platform for Java development, eclipse is still not providing the same comfortable "what you see is waht you get editors" for JavaFX as it is providing for the older technologies. Until eclipse is not deprecating support for Swing and older technologies like SWT and AWT they will be used by programmers.

I did some research one the internet regarding JavaFX so far but I will try to write more articles in the future about it as I intend to write little tools for myself in Java. For this I of course do not want the hustle of maintaining a JEE server all the time. Therefore JavaFX is intersting for me but I am far from beeing an expert, so try it yourself.

Java Architecture for XML Binding (JAXB) provides a fast and convenient way to bind XML schemas and Java representations, making it easy for Java developers to incorporate XML data and processing functions in Java applications. As part of this process, JAXB provides methods for unmarshalling (reading) XML instance documents into Java content trees, and then marshalling (writing) Java content trees back into XML instance documents. JAXB also provides a way to generate XML schema from Java objects.
