Java 6.0 Snapshot Installation

[Stephan Bardubitzki]

Dear Friends,

my OS is Ubuntu6.06 and for development and testing purpose I need to
have the latest Java 6.0 snapshot as the default Java version.

If I try to package and install the binary I get the following output:

fakeroot make-jpkg jdk-6-rc-bin-b90-linux-i586-30_jun_2006.bin
Creating temporary directory: /tmp/make-jpkg.XXXXwMCSIo
Loading plugins: blackdown-j2re.sh blackdown-j2sdk.sh common.sh ibm-j2re.sh ibm-j2sdk.sh j2re.sh j2sdk-doc.sh j2sdk.sh j2se.sh sun-j2re.sh sun-j2sdk-doc.sh sun-j2sdk.sh

No matching plugin was found.
Removing temporary directory: done

Is there a way to package and install non official Java distribution as the default Java version?

Thanks in advance.

Stephan
