Here is the text from a service request I just submitted:

It seems the java path set by the basic installer defaults to /usr/jre. I recommend including the java path selection in the basic installation sequence identical to the advanced. The reason I say this is because I installed java on SLES 11 without any extra path commands and the path was not /usr/jre. I edited the file to reflect the actual path and everything was ok. Here are a few lines from the text installer:

Configuration saved in installer.xml.
