java - Serial version id mismatch issue between server and client class

I am facing issues with serial version id mismatch.

My server is having code with serialVersionID=20150301L;

and myt client code is having diffrent so changed it manually but still facing the same issues.

Error:

java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is: java.io.InvalidClassException: com.fedex.supplies.j2ee.common.client.reqresp.CustomerDataRequest; local class incompatible: stream classdesc serialVersionUID = 20150901L, local class serialVersionUID = -955959537118369236.

I tried option like implementing serilizable,manually defined serialVersionID same as server but getting the same error each time.

Answer

Try the following code

private static final long serialVersionUID = 20150901L;

if you don't make it private and static and final it will be ignored.
