When using Struts2 on WebShpere 6.1.0.25.

1. If type conversion error occur especially for type Date, no
exception will be thrown.
2. Will return to input silently.


For those who has problem using Struts2 version 2.1.x on WebSphere
6.1.0.25, please make sure add a property on WAS

Administrative Console -> Servers -> Application Servers ->
[ServerName] -> Configuration -> Container Settings -> Web Container
Settings -> Web Container -> Configuration -> Additional Properties ->
Custom Properties

1. Add property "com.ibm.ws.webcontainer.invokefilterscompatibility"
with value "true"

2. Restart the server for the custom property to take effect.

You should be able to see the difference. Good luck and have fun.
