How to update Freemarker in ofbiz

[Arjun Rajappan]

I have downloaded freemarker 2.3.22.jar from ofbiz trunk 14.02 version. I
placed under the folder framework/lib.

But still i am getting the error as freemarker.core.ParseException for
Keep_before.

I don't know which are all the files needed to be changed when we updating
freemarker jar file.

Please give me a solution for this. Or updating steps.

Thanks in advance.

Thanks and Regards,
Arjun
