[jira] [Commented] (WW-3025) Parameters get lost when file upload over max size allowed

["Scott Stanlick (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-3025?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13011819#comment-13011819 ] 

Scott Stanlick commented on WW-3025:
------------------------------------

Any movement on this one?  I worked about six hours yesterday on this one before determining the problem was here.  I think the file upload docs should point out this nasty, nasty side effect.  As far as refactoring goes, a more immediate resolution might be to modify the processUpload in JakartaMultiPartRequest to deal with the FileUploadException and populate the processNormalFormField(...) unconditionally.

Also, the workaround link above is dead -- as am I after chasing this nasty pig. :)

Peace,
Scott

> When the uploaded file gets rejected because it's content, size, or because of a general problem an Exception is thrown by the MultiPartRequest class. Exceptions are: InvalidContentTypeException, UnknownSizeException, SizeLimitExceededException, and FileUploadException. This can lead to serious problems within the application because the other parameters from the upload form get lost. Happening in a profile page for example means that the user data is lost this can lead to a security Exception. In other case this usually just involves a OGNL-Exception. Meaning your field data like personal file name is lost. Workaround found in http://henning.kropponline.de/index.php/2009/01/18/struts2-fileuploadbase-exception/, but the the still keep uploading to server, not secured.
