I want to print to pdf file in javascript, where outputstream and pdfwriter

I am trying to create a PDF from a server-side controller (report) (ireport) with ajax (and so on), and try to return the data to pdfwriter, servletoutputstream, and httpservletresponse. (I do not know exactly what I'm doing, but I'm doing it this way).
The original purpose was to send a server-side pdf file to the client, find the printer and print without a preview window.
Among them, I wrote 'application / pdf' on the server side and 'datetype: text' on the client side ajax (there is an error if I do not use ajax datatype: text)
If you print the results to the console, they will only be listed as unknown code.
Currently I am trying to put it into an iframe frame.
Question!
1. What should I do to use the text string sent to server -> client as pdf or script code?
(I have already asked you two weeks ago)
2. How do I send a pdf to server -> client? I would like to apply it to the screen by expressing it directly in code instead of downloading it. To print out.

dataType : "text",
type: "POST",
contentType: 'application/json; charset=utf-8',
async : false,
success: function(result){
// I want to view PDF contents and directly print to PDF.

please answer my question

XMLHttpRequest js --> java --> js

i'm using XMLHttpRequest to send a variable from the js file to java file in the same project.
My problem and my question is: how i know my URL ?
Here is my code from js file
xhttp = new XMLHttpRequest();
var handlerFunction = getReadyStateHandler(xhttp, getValue);
xhttp.onreadystatechange = handlerFunction;
xhttp.open("POST",/* Location of my java file */,true);
xhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhttp.send(identMsg);
function getValue (body) {
var valueBody = body.getElementByTagName("body")[0];
}
function getReadyStateHandler(xhttp, responseXmlHandler) {
return function(){
if (xhttp.readyState == 4) {
if(xhttp.status == 200) {
responseXmlHandler(xhttp.responseXML);
} else {alert("Http error: " +xhttp.status);}
}
}
}
and the java code
public void doPost (HttpServletRequest xhttp, HttpServletResponse res) throws IOException {
String body = null;
StringBuilder stringBuilder = new StringBuilder();
BufferedReader bufferedReader = null;
try {
InputStream inputStream = xhttp.getInputStream();
if (inputStream != null) {
bufferedReader = xhttp.getReader();
char[] charBuffer = new char[128];
int bytesRead = -1;
while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
stringBuilder.append(charBuffer,0, bytesRead);
}
} else {
stringBuilder.append("");
}
} catch(IOException ex) {
throw ex;
} finally {
if(bufferedReader != null) {
try {
bufferedReader.close();
}catch (IOException ex2){
throw ex2;
}
}
}
body = stringBuilder.toString();
res.setContentType("application/xml");
res.getWriter().write(body);
}
what is missing?
EDIT: I need to get URL in the js side.

You can have the URL in js with document.location.href

Base64 encoded String is not transfererd to WebView

This line
dojs("jQuery('#result').html('"+encoded+"')");
is not working and not displaying encoded String on WebView. Other codes are working without problem.
If I replace
dojs("jQuery('#result').html('"+encoded+"')");
line with
Toast.makeText(this, encoded, Toast.LENGTH_SHORT).show();
it displays encoded String on Toast.
public void dojs(String command) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
webView.evaluateJavascript(command, null);
}
else {
webView.loadUrl("javascript:" + command);
}
}

ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
if (type=="png") {
bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream);
} else {
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, byteArrayOutputStream);
}
byte[] byteArray = byteArrayOutputStream .toByteArray();
String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT);
dojs("jQuery('#result').html('"+encoded+"')");
} catch (FileNotFoundException e) {

} catch (IOException e) {
dojs("jQuery('#result').html('"+e.getMessage()+"')");
}
} else {
dojs("jQuery('#result').html('png or jpg is accepted')");
}
}
}
}
There is not any error on logcat. please advice.

ImageView is not being set with Image captured through Camera

I have used a CircleImageView using the 'de.hdodenhof:circleimageview:2.0.0' library.
code:
#Override
public boolean onMenuItemClick(MenuItem item){
switch(item.getItemId()){
case R.id.slot1:
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (cameraIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (photoFile != null) {
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photoFile));
startActivityForResult(cameraIntent, CAMERA_IMAGE_REQUEST);
}
}
return true;
case R.id.slot2:
Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(i, "Select Picture"), PICK_IMAGE_REQUEST);
return true;
default:
return true;
}
}
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "Widget_profile_" + timeStamp + "_";
File storageDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, // prefix
".jpg", // suffix
storageDir // directory
);
// Save a file: path for use with ACTION_VIEW intents
photoPath = "file:" + image.getAbsolutePath();
return image;
}
and in the onActivityResult() method:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Bitmap photo = BitmapFactory.decodeFile(photoPath);
profile = (ImageView)findViewById(R.id.profile_image);
profile.setImageBitmap(photo);
} else if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
profile = (ImageView) findViewById(R.id.profile_image);
profile.setImageBitmap(bitmap);
} catch (IOException e) {
e.printStackTrace();
}
}
}
i have created a menu option to select between Gallery and Camera where the Gallery seems to work perfectly, but Camera option doesn't set any image.
public void setImage(View view){
PopupMenu popupMenu = new PopupMenu(MainActivity.this, view);
popupMenu.setOnMenuItemClickListener(this);
popupMenu.getMenu().add(1, R.id.slot1, 1, "Camera");
popupMenu.getMenu().add(1,R.id.slot2,2,"Gallery");
popupMenu.show();
}
Could someone please help me with this?
