This just won't work. The problem is that I do not know enough to even know what is supposed to happen. I can't debug this code. I'd like to store upload to temporary folder "temp" and then to move them to "applets". Please help? The servlet is obviously being accessed, but I can't find the uploaded files... Thanks in advance.
Form (which is created using a scriptlet - I put this here if that could cause problems):
<%
out.write("<p>Upload a new game:</p>");
out.write("<form name=\"uploadForm\" action=\"game.jsp\" "
+ "method=\"POST\" enctype=\"multipart/form-data\">"
+ "<input type=\"file\" name=\"uploadSelect\" value=\"\" width=\"20\" />"
+ "<br><input type=\"submit\" value=\"Submit\" name=\"uploadSubmitButton\" "
+ "onclick = \"submitToServlet2('UploadGameServlet');\">"
+ "</form>");
%>
Which calls this javascript:
function submitToServlet2(newAction)
{
document.uploadForm.action = newAction;
}
Which in turn goes to the servlet (code included in full, since there may be some important element hiding)

throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
if (ServletFileUpload.isMultipartContent(request))
{
try
{
// Create a factory for disk-based file items
FileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
// Parse the request
List items = upload.parseRequest(request); /* FileItem */
File repositoryPath = new File("\\temp");
DiskFileItemFactory diskFileItemFactory = new DiskFileItemFactory();
diskFileItemFactory.setRepository(repositoryPath);
Iterator iter = items.iterator();
while (iter.hasNext())
{
FileItem item = (FileItem) iter.next();
File uploadedFile = new File("\\applets");
item.write(uploadedFile);
}
}
catch (FileUploadException ex)
{
Logger.getLogger(UploadGameServlet.class.getName()).log(Level.SEVERE, null, ex);
}
catch (Exception ex)
{
Logger.getLogger(UploadGameServlet.class.getName()).log(Level.SEVERE, null, ex);
}
}
PrintWriter out = response.getWriter();
try {
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet UploadGameServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet UploadGameServlet at " + request.getContextPath () + "</h1>");
out.println("</body>");
out.println("</html>");
} finally {
out.close();
}
}
}
By trying to access these files without any sort of leading or absolute path, you are trying to write to files (not directories) named
tempandappletsunder the current working directory. In an app server, the current working directory is usually thebinfolder (depends on what app server you use, etc).Some suggestions:
Logger.getLogger(UploadGameServlet.class.getName())references!repositoryPath.getAbsolutePath(), for example.
