Date Fri, 18 Jan 2008 13:19:05 GMT

Benjamin McCann commented on WW-2240:
-------------------------------------

Yes.  It happens every single time, as long as I choose a file and do not submit an empty
input.  I am running WebLogic 10 on Windows XP and the error is logged to C:\appServer\bea\user_projects\domains\base_domain\servers\AdminServer\logs\base_domain.log:
####<Jan 18, 2008 8:08:48 AM EST> <Error> <HTTP> <L3A3454> <AdminServer>

It happens every single time I or a coworker try to use a FileUploadInterceptor at work as
well.  There I am running WebLogic 9.2 on Windows XP.  WebLogic is a free download (http://commerce.bea.com/showproduct.jsp?family=WLS&major=10&minor=1)
though I believe the file size is a bit large.

> Using struts2-core-2.1.0-SNAPSHOT-20071003.jar, I received the following:
> java.lang.NullPointerException
> 	at org.apache.struts2.interceptor.FileUploadInterceptor.intercept(FileUploadInterceptor.java:277)
> 	at com.opensymphony.xwork2.DefaultActionInvocation$1.doProfiling(DefaultActionInvocation.java:229)

> 	at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:226)
> My action was able to access the File, so it must have been something in the cleanup.
 My action was very similar to the one found in this tutorial http://www.roseindia.net/struts/struts2/struts-2-file-upload.shtml
