Previously I blog about Pentaho and succesfully run it in my ubuntu 8.04 box. After a while, I upgrade my pc to ubuntu 8.10 and my pentaho is not working properly. I got below error while trying to create a new database connection.

org.pentaho.ui.xul.XulException:java.lang.NullPointer Exception

Solution for this error is pretty much easy but it take me a while to figure it out.

sudo ln -sf /usr/lib/jvm/java-6-sun/bin/java /etc/alternatives/java

or,to leaves the system in a more consistent state.

sudo update-alternatives –config java

Yep, that’s the only command that we need to run. Pretty much easy right ?

Till then. adios..
