FileUpload dont recognize getFile() method

Hi all,

I am trying to use a FileUpload component for a KM upload. After importing the external libraries (like ones from com.sap.netweaver.bc.util, com.sap.netweaver.bc.rf) some errors are still there at the following lines:

FileUpload fileUpload = (FileUpload)this.getComponentByName("myfileupload");

IFileParam fileParam = fileUpload.getFile();

if(fileParam != null)

{

this.mimetype = fileUpload.getFile().getContentType();

this.resource = fileUpload.getFile().getFileName();

..

}

The errors are:

"Cannot cast from Component to FileUpload"

"the method getFile() is undefined for the type FileUpload."

So it does not recognize the method getFile() of the class FileUpload.

I guess the problem is that some more libraries have to be added, but which ones i dont know so far

I have tried with both AbstractPortalComponent and JSPDynPage, but not working anyhow.

Can someone helps me, it took all my day trying to find out.

Best regards,

Raluca.
