HTTP Status 405 - HTTP method POST is not supported by this URL.

Hi,

I am trying to build a web application from where file can be uploaded to the server.

the html page looks like as follows:-

The web.xml file looks like:-

I am usging tomcat 6.

I have written a FileUploaderServlet that writes the file to the server's local directory.
The FileUploaderServlet looks as follows:-

package com.test;

import java.io.File;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Iterator;
import java.util.List;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.FileCleanerCleanup;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
import org.apache.commons.io.FileCleaningTracker;
import org.apache.commons.io.FilenameUtils;

public class FileUploaderServlet extends HttpServlet{

/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private final String SUPER_DIRECTORY = "E:\\java_workspace\\EclipseProject\\JspProject\\mainFolder\\";
	
	public FileUploaderServlet()
	{
		//super();
	}
	
	/**
	 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
	 */
	@Override
	protected void doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws javax.servlet.ServletException, java.io.IOException {
		// TODO Auto-generated method stub
		super.doGet(request, response);
		doPost(request, response);
		
	}

/**
	 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
	 */
	@Override
	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		// TODO Auto-generated method stub
		super.doPost(request, response);
		
		
		DiskFileItemFactory factory = newDiskFileItemFactory(getServletContext(),new File("c:\\Temp"));
		ServletFileUpload upload = new ServletFileUpload(factory);
		upload.setSizeMax(500000);
		try {
			List<FileItem> items = upload.parseRequest(request);
			
			Iterator<FileItem> iter = items.iterator();
			   while (iter.hasNext()) 
			   {
			       FileItem item = iter.next();

if (item.isFormField()) {
			           //processFormField(item);
			       } else {
			           processUploadedFile(item);
			       }
			   }
			   
			   response.setContentType("text/html");  
	            PrintWriter out = response.getWriter();  
	            out.println("<html><head><title>File upload</title></head><body>Uploaded file.</body></html>");
	           out.close();

} catch (FileUploadException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	
	private void processUploadedFile(FileItem fileItem)
	   {
		
		String userName = "abc"; //get the user name from session
		File dir = new File(SUPER_DIRECTORY+"\\"+userName);
		dir.mkdir();
		String fileName = fileItem.getName();
		if(fileName!=null)
		{
			fileName = FilenameUtils.getName(fileName);
		}
		File uploadedFile = new File(dir.getAbsolutePath()+"\\"+fileName);
		
		try
		{
			   fileItem.write(uploadedFile);
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
		
	   }
	
	public static DiskFileItemFactory newDiskFileItemFactory(ServletContext context,File repository) 
	{
		FileCleaningTracker  fileCleaningTracker = FileCleanerCleanup.getFileCleaningTracker(context);
		DiskFileItemFactory factory = new DiskFileItemFactory(DiskFileItemFactory.DEFAULT_SIZE_THRESHOLD,repository);
		factory.setFileCleaningTracker(fileCleaningTracker);
		
		return factory;
	}

}

Everything works fine and I am even able to get the file on server. But once the doPost() method of the servlet completes, it gives me

HTTP Status 405 - HTTP method POST is not supported by this URL.

Any idea where things are going wrong?

What is the purpose of the following line in your servlet?

oops! my bad.

I removed that but the problem persists.

May be this helps

Hi Swastik,

I have already overridden the doGet and doPost method in the servlet.

Nandini,

Just include the <http-method> element inside servlet mapping section, and see if that helps. Do restart the server after making the changes.

<servlet-mapping> element in web.xml can contain only <servlet-name> and url-pattern.

The schema doesn't allow me to put http-method tag inside it.

It probably it goes under web resource collection section

That is not necessary.

Simply implementing doPost() and not calling the super method should be sufficient.

thanks Bear!

That did the trick.

Would you please tell me why the problem occurs when I make the call to super?

The super instances of the doXyz methods specifically issue a response that says that the method is not supported!
