Mobile Application - Device Null Pointer Exception

Hi

I am trying to find whether the request is from mobile/tablet/normal browser. For that I followed below configuration

I have added spring-mobile-device1.0 jar to class path.


spring.xml
----------------


web.xml
------------


SessionFilter.java
--------------------


Problem: Null Pointer Exception at : Device currentDevice = DeviceUtils.getCurrentDevice(request);

Could any one please assist to resolve this issue..

Can you post the complete stack trace?

Here is stack trace

That's very weird that you would have a Null Pointer Exception on a call to a static method. Are you sure there is no "Caused by" below that stack trace?. Are you sure line 14 is DeviceUtils.getcurrentDevice Do you have a catch clause inside DeviceUtils.getCurrentDevice method?

Did any one solve this problem? Because I'm getting the same as you.

Here is the Class where I'm using the DeviceUtils.getCurrentDevice(request);





Here is my stacktrace error, pretty weird because I'm not getting the cause of the error in the trace...
