system does not see /usr/bin/java

[Mike Basinger]

After installing openjdk-6 I get the following trying to run java from the command line.

The program 'java' can be found in the following packages:
 * java-gcj-compat-headless
 * icedtea-java7-bin
 * j2re1.4
 * kaffe
 * cacao
 * gij-4.1
 * jamvm
 * gij-4.2
 * sablevm
Try: sudo apt-get install <selected package>
bash: java: command not found

java is in /usr/lib/jvm/java-6-openjdk/jre/bin/java, but is not link to /usr/bin/java that some program look for it at.

$ update-alternatives --list java ?

dbasinge@mikebuntu:~$ update-alternatives --list java
/usr/lib/jvm/java-6-openjdk/jre/bin/java

Same here
$ sudo update-alternatives --config java

There is only 1 program which provides java
(/usr/lib/jvm/java-6-openjdk/jre/bin/java). Nothing to configure.

$ java

 * gij-4.2
 * sablevm
Try: sudo apt-get install <selected package>

I solved this by installing another javavm, jamvm (whatever would work I think, kaffe etc), then selecting it:

$ sudo update-alternatives --config java
There are 2 alternatives which provide `java'.

  Selection Alternative
-----------------------------------------------
 + 1 /usr/lib/jvm/java-6-openjdk/jre/bin/java
          2 /usr/bin/jamvm

Press enter to keep the default[*], or type selection number: 2
Using '/usr/bin/jamvm' to provide 'java'.

Then selecting openjdk again:

$ sudo update-alternatives --config java

There are 2 alternatives which provide `java'.

  Selection Alternative
-----------------------------------------------
 + 1 /usr/lib/jvm/java-6-openjdk/jre/bin/java
* 2 /usr/bin/jamvm

Press enter to keep the default[*], or type selection number: 1
Using '/usr/lib/jvm/java-6-openjdk/jre/bin/java' to provide 'java'.

Then I uninstalled jamvm, and it's fine now.

I think it's a bug that OpenJDK does not get configured automatically as java if there are no alternatives

this is unreproducible for me; the java link is installed on my system.

this message is from the command-not-found package and will be updated for hardy
The program 'java' can be found in the following packages:
