Java 5 RC Available, Gold Targeted for this Month

Posted by CowboyNeal on from the test-driving dept.

Trevor Leach writes "Sun's Java 5 download page is now serving up J2SE 5.0 RC. There are loads of productivity enhancements in this release, code named 'Tiger,' including generics, enums, autoboxing of primitive types, and metadata. Additionally, the Java Developer's Journal qoutes Sun's Graham Hamilton, chief technologist of Java Software, as specifying September 30 as Tiger's target release date."

    mean, you can't possibly know all that is J2EE properly. But what should one concentrate on, and roughly in what order?

    The only part of J2EE I've actually used my self as a Java programmer is the parts related to servlets. Since you say you use PHP, I take it you're not new to web projects. I'd recommend that you start there - download Tomcat, and learn JSP with taglibs & scriptlets. Then, gradualy move to a three-layer acrhitecture with chaining servlets and JSP for generating HTML only. (I learned PHP by rewriting my pet Servlet project in PHP, maybe the reverse could work for you?)

    Ignore Java 5 for now - it usually takes quite a while for new Java versions to get used in production, especially with J2EE, where you pretty much have to wait for app servers to support new versions before you can even cosider using them yourself.

    I have NOT looked at RC 5, but hope they have either sped up SWING...

    Linux and Solaris users, and new in beta2, Windows users, who have the latest OpenGL drivers and select graphic cards can get native hardware acceleration from Java2D using the following runtime property:

    java -Dsun.java2d.opengl=true -jar Java2D.jar

    I never did find out what an EJB is.
    EJB is a scheme for writing complex business logic in Java. Basically you write the code that does the interesting bits yourself, and then deploy the code into an application called an EJB container which handles most of the boring difficult bits like database integration, transaction management, user authentication and authorization, load balancing, multi-protocol serialization, object discovery, etc.

    I downloaded RC 5 last night, and ran the
    SwingSetDemo. I noticed the GTK look and feel looks better than with JDK 1.4, it (more or less) uses the GTK theme you are using. I did notice a couple of bugs, sliders didn't display correctly, and the InternalFrames don't show up (the console displays a NullPointerException).

    I like the Swing API, but I don't like the emulated Look and Feel. I like the native look and feel of SWT, but I don't like the API. The best solution for someone like me is to use SwingWT.

    It is a wrapper around SWT, using the Swing API, porting existing Swing code to SwingWT is trivial,
    just replace java.awt.* with swingwt.* and javax.swing.* with swingwtx.swing.* and you are done.
