[gentoo-user] Re: Java java java, I miss my java
To answer several questions from several people: 1) I thought java 1.5 wasn't there because it was not found by emerge -s java emerge -s jre emerge -s blackdown At that point I just figured it wasn't there. I'm glad to discover I was wrong. 2) I'm not so much itching to use the features, as I am required to teach them. But the significant ones seem to be - Scanner class which smooths one of the major bumps for beginning Java programmers: how to do input without learning the whole language first. - Autoboxing which allows a looser typing of functionally similar entities (the primitives and their wrapper classes). - Generics (type-safe containers) (not really an intro topic, but I'll be teaching a second course too). - True enum - C-style printf, and varargs (ya!) ++ kevin - Iterator for-loop -- Kevin O'Gorman, PhD -- gentoo-user@gentoo.org mailing list

It works permanently for me with "source ${HOME}/.gentoo/java-env" in ~/.bashrc.

Ooh, thanks for the tip! Edited-- I've got an alias to edit .bashrc,
that's how much I do it, but never thought of doing that. Now I can set
azureus back to the binary in my menu.xml. Thanks a bunch.

The best part is that under 1.5 a persistent problem I'd been having with Swing layout managers has gone away: now when I pack() a JFrame multiple times, I get a proper layout with no anomalous regions. (Sample on request). To me, that's better than the rest of 1.5's features combined! ++ kevin -- Kevin O'Gorman, PhD -- gentoo-user@gentoo.org mailing list

Thaks, all -- I now have a new Java, and know about a few new utilities. But I'm probably still in trouble. The rest at the bottom.

If I search 'eix java', neither blackdown nor Sun comes up (no jre's, actually).

Here's one way of checking: # export declare -x JAVAC="/opt/blackdown-jdk-1.4.2.01/bin/javac" declare -x JAVA_HOME="/opt/blackdown-jdk-1.4.2.01" declare -x JDK_HOME="/opt/blackdown-jdk-1.4.2.01" $ export declare -x JAVAC="/opt/blackdown-jdk-1.4.2.01/bin/javac" declare -x JAVA_HOME="/opt/sun-jre-bin-1.5.0.03" declare -x JDK_HOME="/opt/blackdown-jdk-1.4.2.01" So as you can see, the exported variables for root and the user are different, at least as far as what Java VM are being used-- I don't have the Sun JDK installed, but only the Blackdown, so that's correct too. It doesn't seem to make any difference for the Java executables I've used so far. The idea being, 'export' without parameters will give you a list of the current environment variables in use and their state. Of course, in this case, you could just do a 'java-config -f' for both the user and for root, to confirm what VM each one was using. Hope this helps, Holly -- gentoo-user@gentoo.org mailing list
