Hi there Mike,
Let me explain a bit better. I have a servlet called UploadTest & This is called from a HTML Form.
At the top of this HTML Form I have the following -
<form method="post" action="..\UploadTest" name="Box" ENCTYPE="multipart/form-data">
<input type="file" name="hello">
This places a Text Box & a browse button on the form (which I did not notice yesterday as it was behind other components).
When I hit browse & select a file it uploads the file as expected. But, I dont want to give the user the option to select the file as I want to hardcode the name of the file in the code.
How do I do this?
This is the servlet code -
import java.io.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import com.oreilly.servlet.MultipartRequest;
public class UploadTest extends HttpServlet {
public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
try {
// Blindly take it on faith this is a multipart/form-data request
// Construct a MultipartRequest to help read the information.
// Pass in the request, a directory to save files to, and the
// maximum POST size we should attempt to handle.
// Here we (rudely) write to the server root and impose 5 Meg limit.
MultipartRequest multi = new MultipartRequest(req, "e:\\temp", 5 * 1024 * 1024);
out.println("<HTML>");
out.println("<HEAD><TITLE>UploadTest</TITLE></HEAD>");
out.println("<BODY>");
out.println("<H1>UploadTest</H1>");
// Print the parameters we received
out.println("<H3>Params:</H3>");
out.println("<PRE>");
Enumeration params = multi.getParameterNames();
while (params.hasMoreElements()) {
String name = (String)params.nextElement();
System.out.println("~~" + name);
String value = multi.getParameter(name);
out.println(name + " = " + value);
}
out.println("</PRE>");
// Show which files we received
out.println("<H3>Files:</H3>");
out.println("<PRE>");
Enumeration files = multi.getFileNames();
while (files.hasMoreElements()) {
String name = (String)files.nextElement();
System.out.println("NAME - " + name);
String filename = multi.getFilesystemName(name);
System.out.println("FILENAME - " + filename);
String type = multi.getContentType(name);
System.out.println("TYPE - " + type);
File f = multi.getFile(name);
out.println("name: " + name);
out.println("filename: " + filename);
out.println("type: " + type);
if (f != null) {
out.println("length: " + f.length());
}
out.println();
}
out.println("</PRE>");
}
catch (Exception e) {
out.println("<PRE>");
e.printStackTrace(out);
out.println("</PRE>");
}
out.println("</BODY></HTML>");
}
}
Basically, I want to be able to upload files without any direct interaction from the user.
Thanks,
D
