-- clearly outline your intention of changinging careers in the "Objective" section. For example
"Changing careers from being a developer in JEE based systems to a challenging entry level developer role in SAP based software development, and it is my passion in SAP sustains me to gain SAP certification and hands on experience through self-taught and open source projects."
better say that you were unemployed or something.
Don't do that.
-- You can still emphasize your achievements in hard skills and especially soft skills, but be a bit liberal in the usage of the term "Java/J2EE". Don't splash the term Java/J2EE every where.
-- Try to emphasize a bit more on your SAP. Good luck.
