Hi,
It is more complicated than that. The multipart request has a more convoluted structure and
you should not start from scratch with its processing.
Please get the library FileUpload from Apache Jakarta, study how to operate with it and that will provide you a solution for your problem.
There are also web frameworks that provide transparent file processing (like
Struts etc), but of course your question was about servlets.
Best Regards,
