JBoss: Running Multiple server on same machine but on different port
Please go into the bin directory of your jboss server.
We normally start the jboss server by following command and it runs on the default port mentioned in the jboss configuration file.
/> ./run.sh &
http://localhost:8080/
we can also start the server by binding with the IP address or host name,
/> ./run.sh -b 192.168.1.220 &
http://192.168.1.220:8080/

Ajax Styled Servlet File upload
This is very simple application to upload a file using java servlet like AJAX.
import javax.servlet.Servlet;
import javax.servlet.ServletConfig;
import javax.servlet.http.HttpServlet;
import java.io.*;
import java.util.*;
import javax.servlet.http.*;
import org.apache.commons.fileupload.*;
import javax.servlet.ServletException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class FileUploadServlet extends HttpServlet implements Servlet {
private static final String DESTINATION_DIR_PATH = "/files"; /* directory : where-ever you want to save in disk. as i am saving into the context */
protected File destinationDir = null;
protected PrintWriter out = null;
public void init(ServletConfig config) throws ServletException {
super.init(config);
String destination_realPath = getServletContext().getRealPath(DESTINATION_DIR_PATH);
System.out.println(destination_realPath);
destinationDir = new File(destination_realPath);
if(!destinationDir.isDirectory()) {
throw new ServletException(DESTINATION_DIR_PATH+" is not a directory");
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List uploadedItems = null;
FileItem fileItem = null;
out = response.getWriter();
try {
uploadedItems = upload.parseRequest(request);
Iterator i = uploadedItems.iterator();
System.out.println(uploadedItems.isEmpty() + " : " + i.hasNext());
while (i.hasNext()) {
fileItem = (FileItem) i.next();
if(fileItem.isFormField() == false) {
if(fileItem.getSize() > 0) {
File uploadedFile = null;
String myFullFileName = fileItem.getName(), myFileName = "", slashType = (myFullFileName.lastIndexOf("\\") > 0) ? "\\" : "/";
int startIndex = myFullFileName.lastIndexOf(slashType);
myFileName = myFullFileName.substring(startIndex + 1, myFullFileName.length());
uploadedFile = new File(destinationDir, myFileName);
fileItem.write(uploadedFile);
out.write(destinationDir + "\\" + myFileName );
out.flush();
out.close();
}
}
}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
}
1. Create a web project
/WEB-INF/lib/ under your project.
3. create any html file under your webApp write these following tags
<form action="ajaxupload" enctype="multipart/form-data" method="post" target="iframe">
<input type="file" name="fileTxtUpload">
<input type="submit">
</form>
4. Now you need to write a tagline for iFrame anywhere on the page but outside of <form> </form>.
<iframe name="iframe" id="iframeid" width="0" height="0" style="visibility: hidden"> </iframe>
5. Now create a folder "files" under your webApp. All the uploaded files would be save here.
6. Please copy the servlet class and map approprite in web.xml.
import javax.servlet.Servlet;
import javax.servlet.ServletConfig;
import javax.servlet.http.HttpServlet;
import java.io.*;
import java.util.*;
import javax.servlet.http.*;
import org.apache.commons.fileupload.*;
import javax.servlet.ServletException;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;
public class FileUploadServlet extends HttpServlet implements Servlet {
private static final String DESTINATION_DIR_PATH = "/files"; /* directory : where-ever you want to save in disk. as i am saving into the context */
protected File destinationDir = null;
protected PrintWriter out = null;
public void init(ServletConfig config) throws ServletException {
super.init(config);
String destination_realPath = getServletContext().getRealPath(DESTINATION_DIR_PATH);
System.out.println(destination_realPath);
destinationDir = new File(destination_realPath);
if(!destinationDir.isDirectory()) {
throw new ServletException(DESTINATION_DIR_PATH+" is not a directory");
}
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
FileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List uploadedItems = null;
FileItem fileItem = null;
out = response.getWriter();
try {
uploadedItems = upload.parseRequest(request);
Iterator i = uploadedItems.iterator();
System.out.println(uploadedItems.isEmpty() + " : " + i.hasNext());
while (i.hasNext()) {
fileItem = (FileItem) i.next();
if(fileItem.isFormField() == false) {
if(fileItem.getSize() > 0) {
File uploadedFile = null;
String myFullFileName = fileItem.getName(), myFileName = "", slashType = (myFullFileName.lastIndexOf("\\") > 0) ? "\\" : "/";
int startIndex = myFullFileName.lastIndexOf(slashType);
myFileName = myFullFileName.substring(startIndex + 1, myFullFileName.length());
uploadedFile = new File(destinationDir, myFileName);
fileItem.write(uploadedFile);
out.write(destinationDir + "\\" + myFileName );
out.flush();
out.close();
}
}
}
} catch (FileUploadException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
}
7. if you want to get alert when the file is successfully uploaded, please write the following JS function inside header (<head> .. . . </head>) section.
window.onload = function() {
var iframe = document.getElementById("iframeid"),
textBox = document.getElementById("textBox");
iframe.onload = function(){
/* parsing the data i.e. send from server side */
var filePath = (iframe.contentWindow.document).getElementsByTagName('pre')[0].childNodes[0].nodeValue;
alert("file is saved at your disk " + "\n" + filePath);
}
}
window.onload = function() {
var iframe = document.getElementById("iframeid"),
textBox = document.getElementById("textBox");
iframe.onload = function(){
/* parsing the data i.e. send from server side */
var filePath = (iframe.contentWindow.document).getElementsByTagName('pre')[0].childNodes[0].nodeValue;
alert("file is saved at your disk " + "\n" + filePath);
}
}
