Havilah,
Why are you afraid of JAVA?
Do you have any programing language language? If not, then jumping to ORACLE/SAP may be a tad pre-mature.
Something else to keep in mind is that ORACLE sued and won judgement against SAP/TomorrowNow for copyright theft. Appears that TommorrowNow stole the core design of their software directly from the ORACLE software support. There is a case pending as to the actual amount of damages to issue and licensing agreements.(
