java on wheezy

[Francesco Pietra]

Is any official (= working) advice on getting java at work with wheezy
(specifically in amd64, if relevant)?

What should be installed/reconfigured/uninstalled other than the packages
obtained from wheezy desktop install, followed by upgrading with

deb http://mozilla.debian.net/ experimental iceweasel-beta

e.g., with my amd64 wheezy installation:

java-common
openjdk-6-jre
libservlet2.5-java
icedtea-netx
default-jre
default-jre-headless
libatk-wrapper-java
libxz-java
libatk-wapper-java-jini
libreoffice-java-common
libdb-je-java
libdb-java
libdb5.1-java
libdb5.1-java-jini
libcommons-beanutils-java
libcommons-digester-java
libregexp-java
libjline-java
openjdk-6-jre-headless
libxalan2-java
liblucene2-java
tzdata-java
icedtea-netx-common
icedtea-6-plugin
libhsqldb-java
libjtidy-java
libcu4j-java
ca-certificates-java
ant
libcommons-logging-java
ant-optional
libcommons-collections3-java
libreoffice-base
libcommons-parent-java
libgtksourceview-3.0-commor 3.4.2-1
libxml-commons-resolver1.1- 1.2-7
libxml-commons-external-java 1.4.01-2
virtuoso-opensource-6.1-bin
libvirtodbc0
virtuoso-opensource-6.1-com
jmol
vitruoso-minimal
libdbus-1-3
dbus
many other javascripts...
gjs
libseed-gtk3-0
libmozjs10d


I am not playing with java (useless in the scientific area), however many
molecular structures are shown on the web which require java.

Thanks

My test (and Java app I want to run) is sweethome3d.
Wasn't working on wheezy.
Upgraded to sid. Sweethome3d worked.
Upgraded some days back, now it doesn't work.
Not sure if I'm doing anything wrong. 64-bit.
Haven't tested in a browser.

Well on my system (upto date sid, but 32 bit) running
openjdk7 sweethome3d works properly.

I am not using iceweasel from experimental. But I am using the same
version from Backports on Stable Squeeze 6. Works for me.

What is the output of this for you?

$ update-alternatives --display mozilla-javaplugin.so
mozilla-javaplugin.so - auto mode
link currently points to /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so - priority 1071
Current 'best' version is '/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so'.

$ dlocate /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so
icedtea-7-plugin:amd64: /usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64/IcedTeaPlugin.so

The above from my machine shows that it is handled by the
icedtea-7-plugin:amd64 package.

Note that Java != Javascript. The name Javascript was simply an
attempt to ride on the wave of marketing for Java. It has worked.
Many people think they are related. They are not.

The world of Java seems fraught with programs that are version
specific. Perhaps you are hitting one of those cases. Perhaps Java
in general is working but a particular program is version specific and
doesn't match your version?

For me (I use v 6):

Bob:
You hit the point.
Now, at least from academic centers, I can see all the molecular
structures that require java. Thanks for the lesson
