Here i am embedding the html code in an servlet which I think is not a good practice,actually I am reading the objects from another servlet and then processing it and displaying it in the browser.But is there any way how to separate this html code from the servlet.
Thanks in advance..

I will get the output as:

So If I click on Anagha the userid must be passed to the getJiras which has return type as Map Object and then It should process and display the

Also how can I also display the json array size which is being printed in the browser.The problem is getting complicated day by day,Please help to solve this problem.Thanks in advance
You can create another servlet or use same servlet to make one more get request. That request will call to jira service.
Case 1: Create another servlet, it is similar to what you are doing
Case 2: You can custom your current servlet method doGet. Sample code is below.
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String requestAction = request.get("action");
if("detail".equals(requestAction)) {
services3 service = new services3();
//get result.
} else if("view".equals(requestAction)){
//your current code
}
//add result to response
}

I have implemented drag & drop file uploading in jsp and servlet, but I have a problem. Here is a part of my upload.jsp code:
function dropUpload(event) {
var files = event.dataTransfer.files;
upload(files);
}
function upload(files) {
var formData = new FormData();
for (var i in files) {
formData.append('file[]', files[i]);
}
var xhr = new XMLHttpRequest();
xhr.onload = function() {
console.log(xhr.responseText);
};
xhr.open("POST", "UploadServlet");
xhr.send(formData);
}
I use the getParts() method in my UploadServlet.java code to get the files that the user uploads, like below:
public class UploadServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* #see HttpServlet#HttpServlet()
*/
public UploadServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* #see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.getRequestDispatcher("login.jsp").forward(request, response);
}
/**
* #see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String savePath = "D:\\TEST";
// creates the save directory if it does not exists
File fileSaveDir = new File(savePath);
if (!fileSaveDir.exists()) {
fileSaveDir.mkdir();
}
response.getWriter().println(request.getParts().size());
for (Part part : request.getParts()) {
if(part.getContentType() == null) {
continue;
}
response.getWriter().println("Part name: " + part.getName());
response.getWriter().println("Size: " + part.getSize());
response.getWriter().println("Content Type: " + part.getContentType());
String fileName = extractFileName(part, response);
response.getWriter().println(fileName);
part.write(savePath + File.separator + fileName);
response.getWriter().println("already upload file:" + fileName);
response.getWriter().println("=============================================");
}
}
private String extractFileName(Part part,HttpServletResponse response) throws IOException {
String contentDisp = part.getHeader("content-disposition");
//response.getWriter().println(contentDisp);
String[] items = contentDisp.split(";");
for (String s : items) {
if (s.trim().startsWith("filename")) {
return s.substring(s.indexOf("=") + 2, s.length()-1);
}
}
return "";
}
But I can't understand that if I upload 2 files with upload.jsp,
the value of getParts().size() is 4; it means that I always have 2 more files than exactly what I upload, and the 2 external files name and contentType will be null, and it will cause an error in part.write().
My solution is use the if statement
if(part.getContentType() == null) {
continue; }
to ignore the null file.
Can somebody tell me why this happens?
I have a problem when retrieving data (an Integer value) between servlets, when I want to multiply the value retrieved. I have this function in my first servlet,
private int totalNumberOf(Map<String,Integer> cart) {
int counter = 0;
for (String key : cart.keySet())
counter += cart.get(key);
return counter;
}
And I also have the attribute for it (placed at the end of the doGet() method)...
req.setAttribute("quantity", new Integer(totalNumberOf(cart)));
, a function that gives me the total number of products that are in the cart, which updates the value every time I add something to the cart so when I finish buying I can get an updated value of the number of products that are currently in the cart.
The problem comes now, when I try to do the fictional checkout (because I just have a generic price for every type of product) and I have to multiply the number of items by the generic price (here's where the NullPointer shows up).
Here's the code of my second servlet,
#Override
public void doGet(HttpServletRequest req, HttpServletResponse res ) throws IOException, ServletException {
HttpSession session = req.getSession();
Integer quantity;
int toPay;
int genericValue = 20;
quantity = (Integer) req.getAttribute("quantity");
toPay = quantity.intValue() * genericValue; // NullPointer
}
I've tried everything in every way but I can't get rid of that ugly NullPointer. Hope you can help me a bit with this...

Besides the refactoring and optimisation that your code might need, the problem you are refering to is that your are setting the attribute "cantidad" to the request instead of the session.
In Servlet1, replace this
req.setAttribute("cantidad", numeroTotalLibros(carrito));
with this
session.setAttribute("cantidad", numeroTotalLibros(carrito));
And in Servlet3, replace this
cantidadLibro = (Integer) req.getAttribute("cantidad");
with this
cantidadLibro = (Integer) session.getAttribute("cantidad");
The reason is that you are forwarding your request from Servlet1 to Servlet2, and so in Servlet2 you can access the "forwarded" request and all its attributes, BUT Serlvet3 is called independently at a later stage. I guess that is when you press "Pagar" in the rendered HTML page. Therefore, you can no longer access those attributes via the request because it is a different request. You can instead access them via the session if you stored them there previously.
Hope this helps.
Have you ever heard about debugging tools?
Your quantity variable has null value, it could be because of abscense attribute quantity in request. That is why you got NPE: null * (primitive numeric constant) -> NullPointerException.
From your code it it looks like "quantity.intValue()" throws your null pointer because quantity is null. Try this:
#Override
public void doGet(HttpServletRequest req, HttpServletResponse res ) throws IOException, ServletException {
HttpSession session = req.getSession();
Integer quantity = 0;
int toPay;
int genericValue = 20;
if (req.getAttribute("quantity") != null) {
quantity = (Integer) req.getAttribute("quantity");
}
toPay = quantity.intValue() * genericValue;
}
Notice not only do I initialize quantity with a value of 0 (so that it is not null) I also add a null check to "req.getAttribute("quantity")" so that you do not assign null to quantity in the case where .getAttribute returns null.
It's likely that your getAttribute function returned null. Remember to do null checking in code. I suggest a if (quantity != null) check before you call .intValue()
Another possible solution would be to check what .getAttribute() returned instead of checking what quantity was set to. You could also give quantity a default value.
if (req.getAttribute("quantity") == null) {
quantity = 0;
} else {
quantity = (Integer) req.getAttribute("quantity");
}

If you are using spring, you can use RestTemplate. From the docs:
String uri = "http://example.com/hotels/1/bookings";
PostMethod post = new PostMethod(uri);
// create booking request content
String request = post.setRequestEntity(new StringRequestEntity(request));
httpClient.executeMethod(post);
if (HttpStatus.SC_CREATED == post.getStatusCode()) {
Header location = post.getRequestHeader("Location");
if (location != null) {
System.out.println("Created new booking at :" + location.getValue());
}
}
Something like that should work (with the parameters being a Map<String,String>):
StringBuffer data = new StringBuffer();
if (parameters != null && parameters.size() > 0) {
for (Entry<String, String> e : parameters.entrySet()) {
if (data.length() > 0) {
data.append('&');
}
data.append(URLEncoder.encode(e.getKey(), "UTF-8")).append("=").append(URLEncoder.encode(e.getValue(), "UTF-8"));
}
}
String parametersAsString = data.toString();
// Send data
URL local_url = new URL(url);
URLConnection conn = local_url.openConnection();
conn.addRequestProperty("Content-Type", "text/xml; charset=utf-8");
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(parametersAsString);
wr.flush();
break;
