Java SecurityException: signer information does not match

Question

I recompiled my classes as usual, and suddenly got the following error message. Why? How can I fix it?

java.lang.SecurityException: class \"Chinese_English_D         


        

Answer 1

A simple way around it is just try changing the order of your imported jar files which can be done from (Eclipse). Right click on your package -> Build Path -> Configure build path -> References and Libraries -> Order and Export. Try changing the order of jars which contain signature files.
