Problem when upload file in portlet GateIn.

[hieuhn]

I write the portlet that upload file to server. this is simple upload example from http://livedemo.exadel.com/richfaces-demo/richfaces/fileUpload.jsf?c=fileUpload&tab=usage . And I config the upload file will store to temp file in web.xml:

   <filter>
        <filter-name>Seam Filter</filter-name>
        <filter-class>org.jboss.seam.servlet.SeamFilter</filter-class>
        <init-param>
                <param-name>createTempFiles</param-name>
                <param-value>true</param-value>
        </init-param>
        <init-param>
                <param-name>maxRequestSize</param-name>
                <param-value>2000000</param-value>
        </init-param>
</filter>

Then I deploy and run it on server. It upload and store to temp file when I run it as standard webapp. But it do not store to temp file when I run it as the portlet of gatein.

I use the code to check where it store:

        if (item.isTempFile()) {
            System.out.println("Temporary File."+item.getFile().getAbsolutePath()+item.getFileName());
        }else {
            System.out.println("Byte Array");
        }

I don't know how to fix this problem. Can someone tell  me what exactly I have to do?

Best regards
