JSP upload

I need to implement JSP upload page that upload files to the server. I want to know
if Java API can do that? or we need special component? I don't know how upload file
works internally. All I have now is the following upload form.
<FORM ACTION="process.jsp" METHOD="POST">
<INPUT TYPE="FILE" name="uploadFile">
<INPUT TYPE="SUBMIT"
</FORM>
please advise. thanks!!

Give you a complete FileUpload code based on servlet:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class FileUpload extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.print("File upload success. <a href=\"/jspbook/files/");
out.print("\">Click here to browse through all uploaded ");
out.println("files.</a><br>");
ServletInputStream sis = request.getInputStream();
StringWriter sw = new StringWriter();
int i = sis.read();
for (;i!=-1&&i!='\r';i=sis.read()) {
sw.write(i);
sis.read(); // ditch '\n'
String delimiter = sw.toString();
int count = 0;
while(true) {
StringWriter h = new StringWriter();
int[] temp = new int[4];
temp[0] = (byte)sis.read();
temp[1] = (byte)sis.read();
temp[2] = (byte)sis.read();
h.write(temp[0]);
h.write(temp[1]);
h.write(temp[2]);
// read header
for (temp[3]=sis.read();temp[3]!=-1;temp[3]=sis.read()) {
if (temp[0] == '\r' &&
temp[1] == '\n' &&
temp[2] == '\r' &&
temp[3] == '\n') {
break;
h.write(temp[3]);
temp[0] = temp[1];
temp[1] = temp[2];
temp[2] = temp[3];
String header = h.toString();
int startName = header.indexOf("name=\"");
int endName = header.indexOf("\"",startName+6);
if (startName == -1 || endName == -1) {
break;
String name = header.substring(startName+6, endName);
if (name.equals("file")) {
startName = header.indexOf("filename=\"");
endName = header.indexOf("\"",startName+10);
String filename =
header.substring(startName+10,endName);
ServletContext sc =
request.getSession().getServletContext();
File file = new File(sc.getRealPath("/files"));
file.mkdirs();
FileOutputStream fos =
new FileOutputStream(
sc.getRealPath("/files")+"/"+filename);
// write whole file to disk
int length = 0;
delimiter = "\r\n"+delimiter;
byte[] body = new byte[delimiter.length()];
for (int j=0;j<body.length;j++) {
body[j] = (byte)sis.read();
// check it wasn't a 0 length file
if (!delimiter.equals(new String(body))) {
int e = body.length-1;
i=sis.read();
for (;i!=-1;i=sis.read()) {
fos.write(body[0]);
for (int l=0;l<body.length-1;l++) {
body[l]=body[l+1];
body[e] = (byte)i;
if (delimiter.equals(new String(body)))
break;
length++;
fos.flush();
fos.close();
if (sis.read() == '-' && sis.read() == '-')
break;
out.println("</html>");
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws IOException, ServletException {
doPost(request, response);
}Of course you can also use jakarata's common fileupload,it's much easier.but I had not succeeded on my system.

JSP Uploader on Linux Issue

Hi.
I have a JSP uploader. This works fine on Windows platforms. The linux version works well too, but only with text files. Any other file (.gpeg, .odt, .pdf etc) get corrupted in some way or another on uploading.
Kindly look at the code involved and help me out. Thanks.

JSP that converts office extensions to pdf and then upload them

Hi there !
Im trying to convert office extensions ( .xls, .ppt, etc) to pdf and then upload the resulting file to a server .
currectly im using the upload solution posted by the user anna_DRA here : http://forums.sun.com/thread.jspa?threadID=672874
and as for the conversion im using a solution which uses OpenOffice's lib to do the conversion.I'm going to post the codes of my JSP and my HTML ( which just contains the form to get the file to be converted and uploaded).
observation: the point which is giving me headaches is how to get the file sent by my form, convert it into a File object, use my conversion tool and then deliver it to my upload tool so it can be stored.... i cant seem to get the File object from the request object ( tried getattribute and it returns null....) .

Hello TSN,
Test Screen Name wrote:
Picking just one point: PDF -> EPS -> PDF. This could not possibly do more than one page, because EPS is absolutely by definition a single page format. Therefore you must choose a page when exporting PDF to EPS.
Thanks for your response.
I was thinking Microsoft... which has allowed multi-page eps files for years. But you're correct, this is normally an unsupported .eps format.
I solved the problem over the weekend by doing the following:
1) I removed the suspect OTF font family but despite doing so, the folder still had two 'corrupted' but unused copies of an italic font. They refused to remove so I had to boot into Win7 SAFE mode to remove.
2) After complete removal of the OTF font family. I reinstalled the OTF font *BUT* only from a different repository (oddly, this other OTF font set is slightly larger per font).
3) Once installed, I tested with Flare, published and uploaded to Crocodoc SUCCESSFULLY. Yeah!
I don't have anymore time to test but the questions remain, such as, was it one or more of the following issues:
a) Flare has a problem handling some OTF fonts or cannot error correct (the way other programs do) for marginal fonts or font errors?
b) Was it the two corrupted fonts in the Windows/fonts folder?
c) Was it the slightly different OTF fonts that I am no longer using?
Take care

Error in uploading excel file using Java pages

Hello,
We are using oracle ERP (R12.1.1) and we have developed one JSP page to upload an excel.
After selecting the excel and browse button is clicked we are gettign the OLE stream error when the excel file is .csv or .xlsx. There is no issue with .xls excel files. For loading the excel data to custom table we are using the "jxl-2.6.jar".
Can we get higher version of "jxl-2.6.jar to support CSV upload?
Thanks.

Are you Registered this jsp upload page to EBS before test?
You have to register the page to EBS first.
Regards,
Dilip

How to get the pull path name from a file upload window

Hello everyone!
I have encountered the following problem with the following JSP code:
<form method="post" action="filename.jsp">
Upload JAVA program:
<input type=file size=20 name="fname" accept="java">
<input type=submit value="go">
</form>
<%
String s = "";
if (request.getParameter("fname") != null)
s = request.getParameter("fname")
%>
The value of s is alway the filename. However I want to get the full path in addition to the filename, so that I can read the file. Does anyone know how to get the pull name of the file?
thanks a lot in advance,

Dear Sir,
thanks a lot for your reply. Please let me explain what I intended to do: I want to upload a file from the local machine and then read the content of the file. Therefore I need to the fullpath of the filename like /var/local/file.java instead of file.java. The latter is what I got.
The problem I have with your code is that the function like "request.getServerScheme()" is not recognized. Maybe is it because I didn't install servelet package? I only installed javax package btw. Also my application runns on Tomcat server if this could give you some information. The error message I had is as follows:

Getting extra things in the uploaded file by flex file upload

Hi,
I am working on a application where I am using adobe flex. I
have a requirement wher I have to upload file to the server. System
allows user to browse file from local machine and flex uploads it
to the server.
Now there is a upload url, its a jsp page which gets
mutipart/form-data content from the request, opens an outputstream
and writes the content of the inputstrem to the file.
fileUpload.mxml

Hi Naseem,
You need a multipart request parsing utility. Check commons-fileupload for example.

Upload csv file data to sql server tables

Hi all,
I want clients to upload csv file from their machines to the server.
Then the program should read all the data from the csv file and do a bulk insert into the SQL Server tables.
Please help me of how to go about doing this.
Thanx in advance.....

1) Use a multipart form with input type="file" to let the client choose a file.
2) Get the binary stream and put it in a BufferedReader.
3) Read each line and map it to a DTO and add each DTO to a list.
4) Persist the list of DTO's.

Upload files using usp

I have a html form where the user browse for a file and submit the form. Then it calls a JSP page to upload the file on to the database. Pls help me to do this.

Not one to spoon-feed, but here's something to get you started. I don't know where I got this code from so I can't credit anyone....
The HTML form for browsing for the file:
<form action="upload.jsp" method="POST" enctype="multipart/form-data">
     
     <input type="file" name="theFile"/>
     <br>
     <input type="submit"/>
</form>The JSP (upload.jsp) for receiving the form:

<%@ page import="java.io.*" %>
<%
     String contentType = request.getContentType();
     System.out.println("Content type is :: " +contentType);
     if ((contentType != null) && (contentType.indexOf("multipart/form-data") >= 0))
          DataInputStream in = new DataInputStream(request.getInputStream());
          int formDataLength = request.getContentLength();
          byte dataBytes[] = new byte[formDataLength];
          int byteRead = 0;
          int totalBytesRead = 0;
          while (totalBytesRead < formDataLength)
               byteRead = in.read(dataBytes, totalBytesRead, formDataLength);
               totalBytesRead += byteRead;
          String file = new String(dataBytes);
          String saveFile = file.substring(file.indexOf("filename=\"") + 10);
          //out.print("FileName:" + saveFile.toString());
          saveFile = saveFile.substring(0, saveFile.indexOf("\n"));
          //out.print("FileName:" + saveFile.toString());
          saveFile = saveFile.substring(saveFile.lastIndexOf("\\") + 1,saveFile.indexOf("\""));
          //out.print("FileName:" + saveFile.toString());
          //out.print(dataBytes);
          int lastIndex = contentType.lastIndexOf("=");
          String boundary = contentType.substring(lastIndex + 1,contentType.length());
          //out.println(boundary);
          int pos;
          pos = file.indexOf("filename=\"");
          pos = file.indexOf("\n", pos) + 1;
          pos = file.indexOf("\n", pos) + 1;
          pos = file.indexOf("\n", pos) + 1;
          int boundaryLocation = file.indexOf(boundary, pos) - 4;
          int startPos = ((file.substring(0, pos)).getBytes()).length;
          int endPos = ((file.substring(0, boundaryLocation)).getBytes()).length;
          FileOutputStream fileOut = new FileOutputStream(saveFile);
          //fileOut.write(dataBytes);
          fileOut.write(dataBytes, startPos, (endPos - startPos));
          fileOut.flush();
          fileOut.close();
          out.println("File saved as " +saveFile);
%>The file should get created in your system32 directory; you can change the path to save elsewhere.
I think there are shortcomings to this code , for example, if you put other fields in the form, I don't think it'll work. But it should be good enough for a simple upload or atleast to get you started with this.

How-to navigate to a JSF JSP that is nested in a sub-directory???

Here is the navigation rule from faces-config.xml
<navigation-rule>
<from-view-id>/index.jsp</from-view-id>
<navigation-case>
<from-outcome>next</from-outcome>
<to-view-id>/upload/uploadImage.jsp</to-view-id>
</navigation-case>
</navigation-rule>
Here is the web content directory structure
/upload/upLoadImage.jsp
index.jsp
The result is:
404 not found
jsp error
Request URI:/fileupload-ViewController-context-root/upload/uploadImage.jsp
Exception:
OracleJSP:java.io.FileNotFoundException: /upload/uploadImage.jsp
How do I fix the navigation or does everything have to be at the same directory level?
Regards,
Al Malin

Does everything have to be at the same directory level?
The <to-view-id/> JSP/html is not required to be at the same directory level as <from-view-id/>
Is the JSP /upload/upLoadImage.jsp and not /upload/uploadImage.jsp?

Uploading File Question

How would I go about writing a JSP that allows a user to upload a file and then the JSP stores the file in a specific directory?

Try
http://www.servlets.com/cos/index.html
It's an Servlet, JSP Upload Package by oreilly. MultiPartParser and MultiRequestParser are suitable for the thing you want to do.
It's very easy and has some examples. I used it for a File Management system at my university!!

Multiple SQL Update within Parent Query

I am tring to extract an image from within a MS SQL image field,
opening the image using JAI, getting the src.getWidth() & src.getHeight
() of each item within the database, and then writing the width and
height back into the database. Everything works except when I goto
write the values into the database - the page (when loading) continues
to work and work and work until I restart the tomcat service. I do not
understand why this would occur, and what is even stranger - I have
very similar code i used for resizing images in the database into a
thumbnail - display and original file sizes using a similar approach...
and that works with out a problem...
I have tried the code with out the inner update query - it works. I
tried with just the selection of a single specific item in the first
query and that works, but when I try multiple updates the second query
appears to stall.
The code is as follows.:
<%@ page language="java" import="javax.servlet.*,javax.servlet.http.*,java.io.*,java.util.*,java.sql.*,javax.media.jai.*,java.awt.*,java.awt.image.*,java.awt.Graphics.*,java.awt.geom.*,java.awt.image.renderable.*,javax.media.jai.widget.*,com.jspsmart.upload.*,java.net.*,com.sun.media.jai.codec.*"%>

Use of input type="file"

Hellow
How can I use the HTML tag <input type="file" > in jsp/servlets ?
how can I got the file and saving it?

Take a look at this page: http://search.java.sun.com/search/java/?qt=jsp+upload&x=39&y=6 - it is a search page and you can use it to find whether or not anyone has asked the question you have before. Often you will find that the question you have asked has been asked before, sometimes as much as 29000 times. It is quicker than asking a question for the first time because you don't have to wait for replies. - they are already there. I also believe that if you don't know understand search engines you are unlikely to understand Java.
To help with your search you may want to know that the "file" input type creates a Multipart request and that the term "com.oreilly.servlets" may well be relevant too.

Welcome to Apple Support Communities. We're users here and do not speak for "Apple Inc." or "Kyocera Inc."
http://usa.kyoceradocumentsolutions.com/americas/jsp/upload/resource/25359/0/Mac Driver3SoftwareGuide1.1.pdf
On the printer driver documentation, Page 5, in the Imaging setting, although the options are not specifically shown, there should be an option on that screen of the print driver to click and select "B/W" or 'black and white' or 'grayscale' or 'monochrome' as Print Mode rather than the "Full Color" option shown in the illustration below.
You access these settings once you have selected 'Print' from an app.
If necessary, you might need to click on the 'Down arrow' button next to the printer name (OS X 10.6), or 'Show Details' button at the bottom of the print dialog box (OS X 10.8) to see additional settings.
