[jboss-user] [JBoss Seam] - Seam Filter + Commons fileupload problem

[Holger Prause]

Hello,

i am using the commons file upload api in a servlet to upload files.

I noticed when declaring the seam filter in web.xml


  |     <filter>
  |         <filter-name>Seam Filter</filter-name>
  |         <filter-class>org.jboss.seam.web.SeamFilter</filter-class>
  |     </filter>
  | 
  |     <filter-mapping>
  |         <filter-name>Seam Filter</filter-name>
  |         <url-pattern>/*</url-pattern>
  |     </filter-mapping>
  | 

common file upload dont recognizes the multipart content anymore
(statement returns false)

  | boolean isMultipart = ServletFileUpload.isMultipartContent(request);
  | 

Well i also tested this on other upload apis(oreilly, seam fileupload) and it seems only to be a problem with the commons fileupload api(commons-fileupload-1.2).

I got 2 questions on this.

1) Does the Seam Web Filter do something "unusual" to the request object?
2) i noticed when i declare the filter this way:


  |     <filter-mapping>
  |         <filter-name>Seam Filter</filter-name>
  |         <url-pattern>*.seam</url-pattern>
  |     </filter-mapping>
  | 

  it works ,will i have any drawbacks with that solution?

Thx very much,

Bye
