Possibly a CLASSPATH problem, where you have an older class of Business that did not
implement Serializable, which WL Classloader is picking up instead of the new one.
Try deleting all your classes, recompile, check the CLASSPATH of WL startup, and even
put
debug code in your SLSB (if(!(business instanceof Serializable) ...)
