Websphere clusters + Struts application

Question

I have one Struts application, which is deployed on Websphere:

• Websphere Server
  • Cell
    • Cluster-1
    • Cluster-2

I have deployed same application on both clusters.

• On cluster 1, my application works fine.

• On cluster 2, my application is not working properly. On loading the application it shows below error

  SRVE0190E: File not found: /<bean:message key='path' />/SomeCSS.css

What could be the problem ?
