Getting Groupwise to work on Ubuntu 64bit (9.04)

Just a quick post on what i did to get Groupwise up and running on Ubuntu 64bit:

1) Installed a 32bit virtual Ubuntu machine, and converted the Groupwise installer to a .deb package with “alien -c filename”.

2) Moved the .deb package back to the host machine.

3) Installed 32bit java libraries “sudo apt-get install ia32-sun-java6-bin”

4) Forced installation of the Groupwise client “sudo dpkg -i –force-architecture novell-groupwise-gwclient_8.0.0-84911_i386.deb”

5) And it works 🙂

Getting the exception “org.apache.jasper.JasperException: java.lang.NumberFormatException” when developing a JavaEE-app?

If you are basing yourself on data from a query, make shure that you are doing a SELECT against the table name and NOT the individual fields!


Cron commands not working when outputting to stderr(2>&1)

The error:

username@host:/home/foo> fetchmail -f /opt/rt-fetchmail/fetchmail 2>&1 /dev/null
Enter password for username@/dev/null:

Solution: Change the cron entry / command to the following:

fetchmail -f /opt/rt-fetchmail/fetchmail > /dev/null 2>&1

This will stop -all- output from appearing.
