I am using Thymeleaf with Spring boot, I am generating PDF file from Thymeleaf template using ITextRenderer, I have some Unicode (HEX) value to display currency symbols but it does't render Unicode characters
I have taken currency symbol Unicode from this URL Currency Unicode reference
Here below is my Java code to generate PDF from Thymeleaf template
String html = templateEngine.process("templates/Quote", context);
FileOutputStream os = null;
File parentDirectory=null;
try {
OutputStream outputStream = new FileOutputStream(quoteNumber+".pdf");
BufferedOutputStream bs= new BufferedOutputStream(outputStream);
ITextRenderer renderer = new ITextRenderer();
renderer.setDocumentFromString(html);
renderer.layout();
renderer.createPDF(bs,true);
outputStream.close();
Assert.notNull("greeting", "The templateName can not be null");
final Context ctx = new Context();
String processedHtml = templateEngine.process("greeting", ctx);
String fileName = UUID.randomUUID().toString();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
log.error("File not found >>> ",e);
} catch (IOException e) {
// TODO Auto-generated catch block
//e.printStackTrace();
log.error("IO Exception >>> ",e);
}
finally {
if (os != null) {
try {
os.close();
} catch (IOException e) { /*ignore*/ }
}
}
Please help me to display currency symbols in generated PDF

I am having problems getting an image back from the default android gallery. All I want to do is call the Android standard gallery intent and return the uri for the image in my onActivityResult. When I run this code it open the gallery just fine but then it force closes whenever I click on a picture. Any tips for this would be helpful.
private void doGallery() {
Intent galleryIntent = new Intent();
galleryIntent.setType(IJudgeSingleton.IMAGEINTENT);
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(galleryIntent, "Select Picture"), IJudgeSingleton.REQUEST_CODE_GALLERY);
}
case IJudgeSingleton.REQUEST_CODE_GALLERY:
Uri uri = data.getData();
mSingleton.mFileTemp = new File(getMediaPath(uri));
try {
IJudgeSingleton.copy(mSingleton.mFileTemp, mSingleton.mCropFileTemp);
mData.setImageSet(true, mSingleton.mFileTemp.toURI().toString(), true);
mData.setPhoto(true);
}
catch (IOException e) {
Log.d(this.getClass().getName(), "REQUEST_CODE_GALLERY", e);
}
break;
Figured it out my file was pointing to a null so that's what was giving me the force close. Also I had to add change some code around in my onActivityResult for REQUEST_CODE_GALLERY. I have posted the added code below for anyone who has this problem.
case IJudgeSingleton.REQUEST_CODE_GALLERY:
Uri uri = data.getData();
//This takes the uri/image returned from the gallery intent a places it into a file.
final int chunkSize = 1024; // We'll read in one kB at a time
byte[] imageData = new byte[chunkSize];
try {
InputStream in = getContentResolver().openInputStream(uri);
OutputStream out = new FileOutputStream(mSingleton.mFileTemp); // I'm assuming you already have the File object for where you're writing to
int bytesRead;
while ((bytesRead = in.read(imageData)) > 0) {
out.write(Arrays.copyOfRange(imageData, 0, Math.max(0, bytesRead)));
}
in.close();
out.close();
} catch (Exception ex) {
Log.e(this.getClass().getName(),"REQUEST_CODE_GALLERY");
}
// mSingleton.mFileTemp = new File(getMediaPath(uri));
try {
IJudgeSingleton.copy(mSingleton.mFileTemp, mSingleton.mCropFileTemp);
mData.setImageSet(true, mSingleton.mFileTemp.toURI().toString(), true);
mData.setPhoto(true);
}
catch (IOException e) {
Log.d(this.getClass().getName(), "REQUEST_CODE_GALLERY", e);
}
break;
case IJudgeSingleton.REQUEST_CODE_DEFAULT_CAPTURE:
mData = data.getParcelableExtra(IJudgeSingleton.SURVEY_INTENT);
showListView();
completedIntent = false;
I'm trying to Open the CMD Using java + Applying code to it to open an .jar so the applications output is shown in the .bat file.
can someone tell me how to do it?
This is the code it got,it does run excecute the file but the CMD doesnt show.
btnTest.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
String Bat = "C:"+File.separatorChar+"Users"+File.separatorChar+"Gebruiker"+File.separatorChar+"AppData"+File.separatorChar+"Local"+File.separatorChar+"Temp"+File.separatorChar+"hexT"+File.separatorChar+"run.bat";
Runtime rt = Runtime.getRuntime();
try {
rt.exec(Bat);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
Edited: This works for me:
String Bat = "C:\\app.bat"; //Try to use \\ as path seperator
try {
Runtime.getRuntime().exec("cmd /c start " + Bat);
} catch (IOException e) {
e.printStackTrace();
}
Define this :
FileWriter writer;
then in your try/catch do the following :
try {
writer = new FileWriter("test.txt");
Process child = rt.exec(Bat);
InputStream input = child.getInputStream();
BufferedInputStream buffer = new BufferedInputStream(input);
BufferedReader commandResult = new BufferedReader(new InputStreamReader(buffer));
String line = "";
try {
while ((line = commandResult.readLine()) != null) {
writer.write(line + "\n");
}
writer.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
This will read the output as a buffer line by line and write it into a text file
I have two classes. MetaDataExtractor(GUI) and MetaData.
MetaData has the method which extracts the metadata from an image. MetaDataExtractor is designed to display the data in a JTextPane. (Please excuse the class names. I know it's a little confusing. I'm fairly new to Java).
MetaDataExtractor:
LongitudeField.setText("" + MetaDataTags.getLongitude());
MetaData:
public String getLongitude() {
try {
Metadata metadata = ImageMetadataReader.readMetadata(jpegFile);
if (metadata.containsDirectory(GpsDirectory.class)) {
GpsDirectory gpsDir = (GpsDirectory) metadata.getDirectory(GpsDirectory.class);
GpsDescriptor gpsDesc = new GpsDescriptor(gpsDir);
String Longitude = "" + gpsDesc.getGpsLongitudeDescription();
}
} catch (ImageProcessingException ex) {
Logger.getLogger(MetaData.class.getName()).log(Level.SEVERE, null, ex);
System.out.println("Error 1");
} catch (IOException ex) {
Logger.getLogger(MetaData.class.getName()).log(Level.SEVERE, null, ex);
System.out.println("Error 2");
}
return longitude;
}
If I set the longitude to be displayed in the JTextPane, it returns "null". If however, I set it to print out on the command line, it prints the longitude fine?
Please excuse me if its a simple solution. I'm still getting to grips with Java.
Java is case sensitive and declare firstly your variable outside of try & catch statement.
Use a IDE like Eclipse to reduce syntax errors like these.
so you should have :
public String getLongitude() {
String longitudeDesc ="";
try {
Metadata metadata = ImageMetadataReader.readMetadata(jpegFile);
if (metadata.containsDirectory(GpsDirectory.class)) {
GpsDirectory gpsDir = (GpsDirectory) metadata.getDirectory(GpsDirectory.class);
GpsDescriptor gpsDesc = new GpsDescriptor(gpsDir);
longitudeDesc = "" + gpsDesc.getGpsLongitudeDescription();
}
} catch (ImageProcessingException ex) {
Logger.getLogger(MetaData.class.getName()).log(Level.SEVERE, null, ex);
System.out.println("Error 1");
} catch (IOException ex) {
Logger.getLogger(MetaData.class.getName()).log(Level.SEVERE, null, ex);
System.out.println("Error 2");
}
return longitudeDesc ;
}
I have researched and tried to refer back to my fileChooser.getSeletedFile() in my save as action but can not work out how to check whether or not a file has been created. Here is my attempted code so far:
Save as code(works well):
public void Save_As() {
fileChooserTest.setApproveButtonText("Save");
int actionDialog = fileChooserTest.showOpenDialog(this);
File fileName = new File(fileChooserTest.getSelectedFile() + ".txt");
try {
if (fileName == null) {
return;
}
BufferedWriter outFile = new BufferedWriter(new FileWriter(fileName));
outFile.write(this.jTextArea2.getText());//put in textfile
outFile.flush(); // redundant, done by close()
outFile.close();
} catch (IOException ex) {
}
}
"Save" code doesn't work:
private void SaveActionPerformed(java.awt.event.ActionEvent evt) {
File f = fileChooserTest.getSelectedFile();
try {
if (f.exists()) {
BufferedWriter bw1 = new BufferedWriter(new FileWriter(fileChooserTest.getSelectedFile() + ".txt"));
bw1 = new BufferedWriter(new FileWriter(fileChooserTest.getSelectedFile() + ".txt"));
String text = ((JTextArea) jTabbedPane1.getSelectedComponent()).getText();
bw1.write(text);
bw1.close();
} else {
Save_As();
}
} catch (Exception ex) {
ex.printStackTrace();
}
}
Instead of storing an instance to the JFileChooser rather store an instance to the File (wich will be null before any save has been performed). In your SaveActionPerformed method check if the file is null. If it is null then do a Save_As and store the selected file in your file variable, if it is not null then do a normal save into the file.
I want to get the XML in atom format of a GoogleDocs spreadsheet using the [generateAtom(..,..)][1] method of the class BaseEntry which a SpreadsheetEntry inherits. But I don't understand the the second parameter in the method, ExtensionProfile. What is it and will this method call suffice if I just want to get the XML in atom format?
XmlWriter x = new XmlWriter();
spreadSheetEntry.generateAtom(x,new ExtensionProfile());
[1]: http://code.google.com/apis/gdata/javadoc/com/google/gdata/data/BaseEntry.html#generateAtom(com.google.gdata.util.common.xml.XmlWriter, com.google.gdata.data.ExtensionProfile)
From the JavaDoc for ExtensionProfile:
A profile is a set of allowed
extensions for each type together with
additional properties.
Usually if you've got a service, you can ask that for its extension profile using Service.getExtensionProfile().
Elaborating Jon Skeet's answer, you need to instanciate a service like this:
String developer_key = "mySecretDeveloperKey";
String client_id = "myApplicationsClientId";
YouTubeService service = new YouTubeService(client_id, developer_key);
Then you can write to a file using the extension profile of your service:
static void write_video_entry(VideoEntry video_entry) {
try {
String cache_file_path = Layout.get_cache_file_path(video_entry);
File cache_file = new File(cache_file_path);
Writer writer = new FileWriter(cache_file);
XmlWriter xml_writer = new XmlWriter(writer);
ExtensionProfile extension_profile = service.getExtensionProfile();
video_entry.generateAtom(xml_writer, extension_profile);
xml_writer.close();
writer.close();
} catch (IOException e) {
e.printStackTrace();
}
}
Analogously, you can read a file using the extension profile of your service:
static VideoFeed read_video_feed(File cache_file_file) {
VideoFeed video_feed = new VideoFeed();
try {
InputStream input_stream = new FileInputStream(cache_file_file);
ExtensionProfile extension_profile = service.getExtensionProfile();
try {
video_feed.parseAtom(extension_profile, input_stream);
} catch (ParseException e) {
e.printStackTrace();
}
input_stream.close();
} catch (IOException e) {
e.printStackTrace();
}
return video_feed;
}
