Why are there errors with the macromedia.css.LocatorParser class and WebLogic

Question :Why are there errors with the macromedia.css.LocatorParser class and WebLogic?
Answer :WebLogic ships with its own version of the fop.jar, which in turn includes the batik.jar, which is
older and breaks Flex. To resolve this issue, remove the fop.jar from the CLASSPATH in the
startWebLogic.cmd file. This may apply to non-WebLogic servers as well, where batik.jar was
included.
