cache clear issue in gwt

Hi,

I have deployed new version of my application on production server. 

It does not allow user to login and throw below error in my console server.

09:24:20,106 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/]] (http--0.0.0.0-80-33)
 loginrpc: ERROR: The serialization policy file '/v4workflow/FB64C6F0204DFD63FB92E5485E94A4E0.gwt.rpc' was not found; 
did you forget to include it in this deployment?
09:24:20,106 INFO  [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/]] 
(http--0.0.0.0-80-33) loginrpc: WARNING: Failed to get the SerializationPolicy 'FB64C6F0204DFD63FB92E5485E94A4E0'
 for module  a legacy, 1.3.3 compatible, serialization policy will be used.
you may experience SerializationExceptions as a result.

It's cache issue. it works fine. because after clearing cache in my browser

To solve this issue, If I add cache clear header in index.html, 

it will add cost to load js every time at client side and give performance issue.

I got so anwser from Thomas Broyer, I can't understand some portion like

servlet.getServletContext().getResourceAsStream. You can customize this by overriding doGetSerializationPolicy (as said in the JavaDoc).
The file name (resource URL) is built from the request's path and X-GWT-Permutation request 

Refer link:

do you know how to resolve cache clear issue in gwt?

Thanks,

Bhumika Thaker
