I see many different Java terms floating around. I need to install the JDK 1.6. It was my understanding that Java 6 == Java 1.6. However, when I install Java SE 6, I get a JVM that reports as version 11.0!!!??! Who can solve the madness? ...
When looking through the JDK, I often think to myself, "Why isn't this included in the JDK?" I know there's Apache Commons and various other libraries, but there are somethings that are just so fundamental that I feel it should be added to the JDK. What are some things missing that you think should be added to the JDK? ...
I tried to download the JDK last friday and then again today and was "greeted" with the following message: "Your download transaction cannot be approved. Contact Customer Service."

Is there an similar property like System.getProperty("java.home") that will return the JDK directory instead of the JRE directory? I've looked http://java.sun.com/j2se/1.4.2/docs/api/java/lang/System.html#getProperties() and there doesn't seem to be anything for the JDK. ...
Recently I've stumbled upon a class named javax.activation.DataHandler. But while reading the javadoc of JDK6, I was not able to understand the aim and rationale of the framework. If you have have used the framework in real life project, please share your experience and explain what a developer can "earn" from it. ...
I was wondering..There is Sun's JRE, IBM's JRE, BEA's JRE, Oracle's JRE and some more less know JREs in the market. Why is there so many JRE implementations? Does the fact that Sun opened the Java platforms mean that there will be one open JRE / JDK? Or are we going towards what happened with Linux and its many distributions ? ...

Is there a way to build my app using one version of the JRE but have my source conform to another version? I would like to debug my app locally using 1.6 because OS X's 1.6 is much better than 1.4.2, but because of backwards compatibility reasons we actually ship using 1.4.2. ...
I understand there are factors at play here other than what JDK I used in my previous jobs, but a lot has gone on since JDK 1.4, and I haven't used any of the new 1.5 or 1.6 features in a production environment. Can that hurt me significantly? Almost every tutorial I see uses generics, enums, var args, and the like, and I wonder if I'm r...

I am of course familiar with the java.net.URLEncoder and java.net.URLDecoder classes. However, I only need HTML-style encoding. (I don't want ' ' replaced with '+', etc). I am not aware of any JDK built in class that will do just HTML encoding. Is there one? I am aware of other choices (for example, Jakarta Commons Lang StringEscape...
I have a number of projects running on a Hudson slave. I'd like one of them to run Ant under Java6, rather than the default (which is Java5 in my environment). In the project configuration view, I was hoping to find either: An explicit option allowing me to set a custom JDK location to use for this project. A way to set custom environ...

This is a real noob question. When I set up JAVA_HOME using the command line interface I used set JAVA_HOME = C:\Program Files\Java\jdk1.6.0_13 However when I open the JAVA_HOME variable from System>Advanced>Environment Variables the change is not visible. Are these two different settings? I have this question every time I set up a n...

I have a table which maps String->Integer. Rather than create an enum statically, I want to populate the enum with values from a database. Is this possible ? So, rather than delcaring this statically: public enum Size { SMALL(0), MEDIUM(1), LARGE(2), SUPERSIZE(3) }; I want to create this enum dynamically since the numbers {0,1,2,3} ...
