Hi,
I have been using HttpClient version 2.0.1. But have some problems while uploading
multiple files. Please let me know
1. Can I upload multiple files using httpclient api from client to server (client and
server running on different systems).
2. I worked with sample code at
http://www.theserverside.com/articles/article.tss?l=HttpClient_FileUpload. Everything
works fine if I run the sample on the same systems but I cannot do the same by making
the client and server on different systems.
I used the following sample at the above url
Listing 9-6. HttpMultiPartFileUpload.java
package com.commonsbook.chap9;
import java.io.File;
import java.io.IOException;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.methods.MultipartPostMethod;
public class HttpMultiPartFileUpload {
private static String url =
"http://localhost:8080/HttpServerSideApp/ProcessFileUpload.jsp";;
public static void main(String[] args) throws IOException {
HttpClient client = new HttpClient();
MultipartPostMethod mPost = new MultipartPostMethod(url);
client.setConnectionTimeout(8000);
// Send any XML file as the body of the POST request
File f1 = new File("students.xml");
File f2 = new File("academy.xml");
File f3 = new File("academyRules.xml");
System.out.println("File1 Length = " + f1.length());
System.out.println("File2 Length = " + f2.length());
System.out.println("File3 Length = " + f3.length());
mPost.addParameter(f1.getName(), f1);
mPost.addParameter(f2.getName(), f2);
mPost.addParameter(f3.getName(), f3);
int statusCode1 = client.executeMethod(mPost);
System.out.println("statusLine>>>" + mPost.getStatusLine());
mPost.releaseConnection();
}
}
and for processing file upload i used the following JSP
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ page import="org.apache.commons.fileupload.DiskFileUpload"%>
<%@ page import="org.apache.commons.fileupload.FileItem"%>
<%@ page import="java.util.List"%>
<%@ page import="java.util.Iterator"%>
<%@ page import="java.io.File"%>
html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Process File Upload</title>
</head>
<%
System.out.println("Content Type ="+request.getContentType());
DiskFileUpload fu = new DiskFileUpload();
// If file size exceeds, a FileUploadException will be thrown
fu.setSizeMax(1000000);
List fileItems = fu.parseRequest(request);
Iterator itr = fileItems.iterator();
while(itr.hasNext()) {
FileItem fi = (FileItem)itr.next();
//Check if not form field so as to only handle the file inputs
//else condition handles the submit button input
if(!fi.isFormField()) {
System.out.println("\nNAME: "+fi.getName());
System.out.println("SIZE: "+fi.getSize());
//System.out.println(fi.getOutputStream().toString());
File fNew= new File(application.getRealPath("/"), fi.getName());
System.out.println(fNew.getAbsolutePath());
fi.write(fNew);
}
else {
System.out.println("Field ="+fi.getFieldName());
}
}
%>
<body>
Upload Successful!!
</body>
</html>
3. But I could not do the same by making the server and client on different systems.
4. Pl. let me know for the same purpose is there any patch available with current
version released. i.e.2.0.2
5. Is there a way to build Multipart request without putting the Http File Item in the
form.
i.e. dynamically getting the file Items created programmatically at client side
and
passing the Multipart request to the server
thanks,
Srinivas.
