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
