"isMultipartContent(HttpServletRequest) - Static method in class org.apache.commons.fileupload.FileUploadBase Deprecated. Use the method on ServletFileUpload instead."
So why do they use it in your code.
Also, they say "Use the method on ServletFileUpload instead".
That class is suppposed to be in the package: import org.apache.commons.fileupload.servlet.*;
But there is not such a subdirectory in the zip source code I downloaded from the jakarta project.
