[gentoo-user] Which Java Runtime is "best"?

[gentoo-user] Which Java Runtime is "best"?

[Walter Dnes]

  I haven't seen an interesting site using Java for a long while.  I
recently stumbled across http://discover.itsc.uah.edu/amsutemps/ and
decided it would be nice to actually view it.  I haven't had Java on my
machines for a long while.  There are a few Java implementations
available (Sun/Blackdown/IBM/BEA/Kaffe/others?), so my question is...

  - which one gives the least trouble setting up and running?

  Since I'm only going to be using it a few times a month, I'm not too
worried about benchmarks, unless an implementation is excruciatingly
slow.

  I only need a runtime.  I don't know the programming language, so
there's no need for a full-blown development environment.

Take Sun JRE. In terms of headaches per month, the quasi standard
implementation is unbeatable.

I'm on AMD64 and am programming java, too. Until now I haven't had a
problem with SUN JDK (1.6). Of course, it doesn't supply a browser
plugin, but I'm not aware of any JRE doing it at the moment and thanks
to nspluginwrapper, there is no urgent need for it, either.

I have to correct myself. As it seems, GNU-Classpath provides an
nsplugin. I haven't tested it yet (and I won't because I need
emul-linux-x86-java anyway and the current way works for me).

  Thanks for your input everybody.  According to /proc/cpuinfo, I'm
running an "AMD Athlon(tm) 64 Processor 3000+", but it's in 32-bit
mode.  I'll go with Sun Java.

  OK, so I *WAS* going to try the Sun JRE.  It seems that there's no
such animal.  You have to download the fullblown developer's kit...

[m3000][root][~] emerge -pv virtual/jre

These are the packages that would be merged, in order:

  I had always wondered why Sun's Java could be shoehorned into memory-
starved cellphones, but required a full gigbyte of diskspace on a PC,
merely to view a Java applet on a webpage.  Now I know.  Next thing I
looked at was Blackdown...

[m3000][root][~] emerge -pv blackdown-jre

Calculating dependencies... done!
[ebuild  N    ] dev-java/java-config-wrapper-0.15  7 kB

[m3000][root][~] emerge -pv blackdown-jdk

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild  N    ] dev-java/java-config-wrapper-0.15  7 kB
[ebuild  N    ] dev-java/java-config-2.1.6  40 kB

[ebuild  N    ] dev-java/blackdown-jdk-1.4.2.03-r15  USE="-doc (-nsplugin)" 33,571 kB

  The jdk is significantly smaller, and the jre even moreso.  However,
the "(-nsplugin)" scares me.  Does that mean it doesn't have the ability
to view Java applets in Firefox via plugins???  What's the point?  Even
with a desktop PC, a gigabyte here and a gigabyte there, and pretty soon
you're talking real significant diskspace.  I plan on getting an ASUS
EEE 900 soon.  And on that thing, a gigabyte to view webpage applets is a
very bad idea.

Even the Sun JDK is not more than 100MB, I don't see the big deal.  As 
for the plugin, IIRC the Blackdown JRE/JDK have an unpatched security 
issue with the browser plugin, which is why the plugin is turned off.

You may have better luck getting more in-depth answers on the 
gentoo-java mail list.
