Get letters to servlet the right way - java

I have a html jsp form where users can copy their text press submit and pdf is created using Itext . On the other side the servlet gets the data . What happens is when I use some non standard letters it gives me back #^& for these letters . I did use in my servler and both jsp charset=UTF-8 , I am using post method to send data . I am using netbeans and tomcat .
It is not about Itext since when I do System.out.println(variable) it also does not print correctly .

1) You need to set the data content type to utf-8 before submitting the data. Because receiver(in this case, servlet) needs to know what encoding was set(in JSP) for the data before servlet actually decodes the bytes.
ie: request.setCharacterEncoding("UTF-8");
2) <%#page pageEncoding="UTF-8"%> is not used for the java data. This line is used to tell what language the JSP file was written in. ie: English, Chinese. I think you totally misunderstood this line.
Answer Updated:
3) Remove this line >> String(request.getParameter("brokerstext").getBytes("iso-8859-1")), "UTF-8"); You don't need to convert received UTF-8 bytes to iso.
Note: Please post your JSP code

The problem is that when parsing the form fields tomcat doesn't know the charset used.
This is normally resolved using a filter that changes charset in request.
Create the following class:
public class EncodingSetterFilter implements Filter
{
/** Creates a new instance of EncodingSetterFilter */
public EncodingSetterFilter()
{
}
public void init(FilterConfig filterConfig) throws ServletException
{
}
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException
{
servletRequest.setCharacterEncoding("UTF-8");
filterChain.doFilter(servletRequest, servletResponse);
}
public void destroy()
{
}
}
And then configure its usage in web.xml (be sure to specify correct filter class):
<filter>
<filter-name>EncodingFilter</filter-name>
<filter-class>
com.yourpackage.EncodingFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>EncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

c:if with variable from Model

We have a web application in which we need to show one header if we are logged in, and another one if we are not logged in. I would like to render these server side in a JSP file.
Here is my first attempt:
WebDelivery.java
package xyz.toold.cuebox.web;
import java.util.HashMap;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import org.glassfish.jersey.server.mvc.Viewable;
#Path("/")
public class WebDelivery {
#Path("/")
#GET
public Viewable index() {
HashMap<String, Object> model = new HashMap<>();
model.put("LoggedIn", true);
return new Viewable("/index", model);
}
#Path("/search/")
#GET
public Viewable search() {
return new Viewable("/search/index", true);
}
#Path("/user/")
#GET
public Viewable user() {
return new Viewable("/user/index");
}
#Path("/board/details/")
#GET
public Viewable boardDetails() {
return new Viewable("/board/details/index");
}
#Path("/board/")
#GET
public Viewable board() {
return new Viewable("/board/index");
}
#Path("/admin/")
#GET
public Viewable admin() {
return new Viewable("/admin/index");
}
}

The problem is my if never fires, so the header never gets shown. I know that the else is missing. I would have implemented it via having another if, which is inverted.
I also tried not passing a HashMap but a plain boolean, but it did not work either.
This is a link to my GitLab project.
What am I doing wrong, or is this entirely the wrong way to do it?

method doPost, assignment of if in eclipse and servlets

That this wrong in the code? I want to make an answer HttpServlet with an if but "I appear "the left-hand an assignment must be a variable" in the last else, I cannot correctly declare the method, How can I fix it?

thanks.
I see the javascript function calls id="tblGrp". However,
<div id="tblGrp">
<table width="70%" id="tblGrp" align="center" class="sortable">
The id appears multiple times, perhaps giving a problem with jspdf. Without more information of the javascript error, Here are a couple of java alternatives.
1) You can build everything using iText.
2) You can design a report in iReport by constructing a jrxml and use the jasper engine for independent pdf exporting/rendering in your application.
3)Here is additional post for alternative to iText.
[Are there any Java PDF creation alternatives to iText?
Without more info of the javascript error, there isn't much to solve here.

how to redirect to success page through servlet using ajax?

I have a jsp page which takes user name and password and then it redirect to a servlet. Below is jsp code,

Then my servlet checks user name and password and if it is wrong then it gives error text but if it is true then it should be redirect to success page. But it doesn't effect. Below is servlet code,
if(db.loginCheck(userName, password))
{
request.getRequestDispatcher("/main.jsp").forward(request, response);
}else
{
String greetings = "Invalid Username/Password";
response.setContentType("text/plain");
response.getWriter().write(greetings);
}
I got solution. I have changed response of my servlet like this,
if(db.loginCheck(userName, password))
{
response.getWriter().write("1");
}else
{
greetings = "Invalid Username/Password";
response.setContentType("text/plain");
response.getWriter().write(greetings);
}
and on my jsp page i have put this,
<script type="text/javascript">
$(document).ready(function() {
$('#btn-login').click(function() {
var userName = $('#userName').val();
var password = $('#password').val();
var datastr='userName='+userName+'&password='+ password;
$.ajax({
url : 'LoginCheck',
data :datastr,
success : function(responseText) {
if(responseText == "1"){
window.location.assign("/main.jsp");
}else{
$('#ajaxGetUserServletResponse').text(responseText);
}
},
});
});
});
</script>
Try this:
Servlet
if(db.loginCheck(userName, password))
{
String greetings = "Success";
response.setContentType("text/plain");
response.getWriter().write(greetings);
}
else
{
String greetings = "Invalid Username/Password";
response.setContentType("text/plain");
response.getWriter().write(greetings);
}
Jquery:
$.ajax({
url : 'LoginCheck',
data :datastr,
success : function(responseText) {
if(responseText == "Success"){
windows.location.href='/main.jsp';
}else{
windows.location.href='/error.jsp';
});

read jSON response

I am trying to read a json response from my python based backend. I am using this code for accessing the information.
URL for first call
public static final String JSON_RESPONSE_STRING="http://192.168.2.5:8000/mobile/";
URL forsecond call
public static final String PICKUP_DETAILS="http://192.168.2.5:8000/mobile/shippments/";
common method using
public static String GetJSONResponse(String stringUrl) throws IOException
{
StringBuilder response = new StringBuilder();
URL url = new URL(stringUrl);
HttpURLConnection httpconn = (HttpURLConnection)url.openConnection();
if (httpconn.getResponseCode() == HttpURLConnection.HTTP_OK)
{
BufferedReader input = new BufferedReader(new InputStreamReader(httpconn.getInputStream()),8192);
String strLine = null;
while ((strLine = input.readLine()) != null)
{
response.append(strLine);
}
input.close();
}
return response.toString();
}
django url patterns
urlpatterns = patterns('mobile_api.views',
url(r'^$','login_authenticate'),
url(r'^shippments/(?P<id>\w+)','pickup_details'),
url(r'^report/post/','pickup_report')
)
I am using this method twice in my code. For the first time this code is working absolutely fine and parsing the json response .
When I am using this method at other place I am call it
pick_up_id=getIntent().getStringExtra("pickup_id");
String stringUrl=Constants.PICKUP_DETAILS+"555";
String response = null;
try {
response = PickupList.GetJSONResponse(stringUrl);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//String response=GetPickUpDetails(pick_up_id);
System.out.println("second call response"+response);
and getting this response

P.S Also, if there is any problem with the code then why is it working for first call.
NOTE 1 Both the response are json objects I have verified several times.my backend is dJango. On hitting the url on browser I am getting the correct response in .json format
check for csrf_exempt or proper permission for access to the url from app
