So I'm trying to make a billing system in which I want to print a receipt.I was able to do it with some code that I found online,but the font size is too big to print in the 58mm wide paper.I'm not able to adjust the font size.Any kind of help with this issue will be highly appreciated.Thank You.
Here is The Code :
public class PrinterService implements Printable {
public List<String> getPrinters(){
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
PrintService printServices[] = PrintServiceLookup.lookupPrintServices(
flavor, pras);
List<String> printerList = new ArrayList<String>();
for(PrintService printerService: printServices){
printerList.add( printerService.getName());
}
return printerList;
}
#Override
public int print(Graphics g, PageFormat pf, int page)
throws PrinterException {
if (page > 0) { /* We have only one page, and 'page' is zero-based */
return NO_SUCH_PAGE;
}
/*
* User (0,0) is typically outside the imageable area, so we must
* translate by the X and Y values in the PageFormat to avoid clipping
*/
Graphics2D g2d = (Graphics2D) g;
g2d.translate(pf.getImageableX(), pf.getImageableY());
/* Now we perform our rendering */
g.setFont(new Font("Roman", 0, 8));
g.drawString("Hello world !", 0, 10);
return PAGE_EXISTS;
}
public void printString(String printerName, String text) {
// find the printService of name printerName
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
PrintService printService[] = PrintServiceLookup.lookupPrintServices(
flavor, pras);
PrintService service = findPrintService(printerName, printService);
DocPrintJob job = service.createPrintJob();
try {
byte[] bytes;
// important for umlaut chars
bytes = text.getBytes("CP437");
Doc doc = new SimpleDoc(bytes, flavor, null);
job.print(doc, null);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public void printBytes(String printerName, byte[] bytes) {
DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
PrintRequestAttributeSet pras = new HashPrintRequestAttributeSet();
PrintService printService[] = PrintServiceLookup.lookupPrintServices(
flavor, pras);
PrintService service = findPrintService(printerName, printService);
DocPrintJob job = service.createPrintJob();
try {
Doc doc = new SimpleDoc(bytes, flavor, null);
job.print(doc, null);
} catch (Exception e) {
e.printStackTrace();
}
}
private PrintService findPrintService(String printerName,
PrintService[] services) {
for (PrintService service : services) {
if (service.getName().equalsIgnoreCase(printerName)) {
return service;
}
}
return null;
}
}
#FXML
public void printit(ActionEvent actionEvent)
{
PrinterService printerService = new PrinterService();
System.out.println(printerService.getPrinters());
//print some stuff
printerService.printString("POS-58-Series", area.getText());
}
I have a piece of code that does pull with rebase:
private void pullWithRebase(Git git) throws GitAPIException {
git.checkout().setName("master").call();
List<Ref> branches = git.branchList().setListMode(ListBranchCommand.ListMode.ALL).call();
String remoteMasterBranchName = "refs/remotes/origin/master";
for (Ref ref : branches) {
if (remoteMasterBranchName.equals(ref.getName())) {
PullResult result = git.pull().setRemoteBranchName("master").setRebase(true).call();
return;
}
}
}
However it doesn't work if any conflicts occur while merging. If they do occur, I want to accept mine
I ended up just merging two branches and directly resolving any conflicts by modifying files.
private static final String CONFLICT_HEAD_MARKER = "<<<<<<<";
private static final String CONFLICT_BORDER_MARKER = "=======";
private static final String CONFLICT_UPSTREAM_MARKER = ">>>>>>>";
private boolean acceptHead;
public void resolve(File file) throws IOException {
File temp = new File(file.getParent(), "temp" + System.currentTimeMillis());
try(BufferedReader reader = new BufferedReader(new FileReader(file));
BufferedWriter writer = new BufferedWriter(new FileWriter(temp))) {
String currentLine;
boolean removePartition = false;
while((currentLine = reader.readLine()) != null) {
if (currentLine.contains(CONFLICT_HEAD_MARKER)) {
removePartition = !acceptHead;
continue;
} else if (currentLine.contains(CONFLICT_BORDER_MARKER)) {
removePartition = acceptHead;
continue;
} else if (currentLine.contains(CONFLICT_UPSTREAM_MARKER)) {
removePartition = false;
continue;
}
if (!removePartition) {
writer.write(currentLine + System.getProperty("line.separator"));
}
}
}
FileUtils.forceDelete(file);
FileUtils.moveFile(temp, file);
}
Today I was going to pack my game into a Jar to provide to a friend who codes and wanted to see a nice glitch I managed to create. When I went to make it a Runnable jar it would load up in the Command Prompt but throw Resource Not Found errors for Sounds (.ogg's), which was fine because they werent going to be used in the Debug mode it was set to. Then it threw a NullPointerException in TileHanlder.class at initTileMap() line 137.
I am at a loss so I came to StackOverflow because I have spent nearly my entire day on getting a working Jar. I have also tried JarSplice.
My main question is if there is any anomalies you notice or something I didnt do that is leading to resources not being found in the .jar.
ALL CODE AND RESOURCES WERE IN THE SAME JAR, ONE JAR FOR EVERYTHING there were not multiple jars

If You need ANY other resources or information than please let me know and I will be happy to provide so I can get over this. I will also be thinking of other ways, Thank you for any responses!
THINGS WERE CUT OUT DUE TO THE 30k Char Limit on the question text box. Mostly in the insanely crowded AssetHandler.java, it is still there in the git repository though.
I had the very same problem. After searching for a while, I came across this neat solution. See this LWJGL forum post.
public static void main(String[] args) throws SlickException {
/* Set lwjgl library path so that LWJGL finds the natives depending on the OS. */
String osName = System.getProperty("os.name");
// Get .jar dir. new File(".") and property "user.dir" will not work if .jar is called from
// a different directory, e.g. java -jar /someOtherDirectory/myApp.jar
String nativeDir = "";
try {
nativeDir = new File(GameMain.class.getProtectionDomain().getCodeSource().getLocation().toURI()).getParent();
} catch (URISyntaxException uriEx) {
try {
// Try to resort to current dir. May still fail later due to bad start dir.
uriEx.printStackTrace();
nativeDir = new File(".").getCanonicalPath();
} catch (IOException ioEx) {
// Completely failed
ioEx.printStackTrace();
JOptionPane.showMessageDialog(new JFrame(), "Failed to locate native library directory. " +
"Error:\n" + ioEx.toString(), "Error", JOptionPane.ERROR_MESSAGE);
System.exit(-1);
}
}
// Append library subdir
nativeDir += File.separator + "lib" + File.separator + "native" + File.separator;
if (osName.startsWith("Windows")) {
nativeDir += "windows";
} else if (osName.startsWith("Linux") || osName.startsWith("FreeBSD")) {
nativeDir += "linux";
} else if (osName.startsWith("Mac OS X")) {
nativeDir += "macosx";
} else if (osName.startsWith("Solaris") || osName.startsWith("SunOS")) {
nativeDir += "solaris";
} else {
JOptionPane.showMessageDialog(new JFrame(), "Unsupported OS: " + osName + ". Exiting.",
"Error", JOptionPane.ERROR_MESSAGE);
System.exit(-1);
}
System.setProperty("org.lwjgl.librarypath", nativeDir);
}
Bear in mind that you need a lib folder in the same directory. I have mine stored outside of the .jar, but it may be possible to have it inside as well. Also note that it needs to happen before you do any LWJGL stuff, so the main method is a good place.
I would like to know what projects hosted on Google Code that have the most stars, especially when searching by label, like this:
https://code.google.com/hosting/search?q=label%3aAndroid
Sort by stars is not supported on the project search page. Was able to write some page scrapping code to get the required information.
Hope it helps.

I would have say use &sort=stars as they do in the support of google code but it doesn't work well. I'm not sure it's possible unfortunately...
I am creating Multimedia components using core service and everything is working fine. But when Metadata schema fields are defined on the Multimedia schema using which I am creating my Multimedia components then I am getting following error:-
Unable to find http://www.tridion.com/ContentManager/5.0/DefaultMultimediaSchema:Metadata.
This message is displayed when I have given Default Multimedia schema's TCM ID for Multimedia component. As metadata fields are saved in Tridion Database so I first have to retrieve these fields from broker or what is the best solution for this, please suggest. Below is the sample code. Please modify it if someone have any idea for providing default value for metadatafields and how to retrieve them (with/without querying broker DB):-
public static string UploadMultiMediaComponent(string folderUri, string title, string schemaID)
{
core_service.ServiceReference1.SessionAwareCoreService2010Client client = new SessionAwareCoreService2010Client();
client.ClientCredentials.Windows.ClientCredential.UserName = "myUserName";
client.ClientCredentials.Windows.ClientCredential.Password = "myPassword"; client.Open();
ComponentData multimediaComponent = (ComponentData)client.GetDefaultData(
ItemType.Component, folderUri);
multimediaComponent.Title = title;
multimediaComponent.ComponentType = ComponentType.Multimedia;
multimediaComponent.Schema.IdRef =schemaID;
//multimediaComponent.Metadata = "";
StreamUpload2010Client streamClient = new StreamUpload2010Client();
FileStream objfilestream = new FileStream(#"\My Documents\images.jpg",
FileMode.Open, FileAccess.Read);
string tempLocation = streamClient.UploadBinaryContent("images.jpg",
objfilestream);
BinaryContentData binaryContent = new BinaryContentData();
binaryContent.UploadFromFile = tempLocation;
binaryContent.Filename = "images.jpg";
binaryContent.MultimediaType = new LinkToMultimediaTypeData()
{
// for jpg file
IdRef = "tcm:0-2-65544"
};
multimediaComponent.BinaryContent = binaryContent;
IdentifiableObjectData savedComponent = client.Save(multimediaComponent,
new ReadOptions());
client.CheckIn(savedComponent.Id, null);
streamClient.Close();
client.Close();
Console.WriteLine(savedComponent.Id);
//}
}
I don't know why your code not working but following code is working for me
public static ComponentData GenerateMultiMediaComponent(TridionGeneration tridionGeneration, XmlData newsArticle, string componentName)
{
try
{

ComponentData componentData = (ComponentData)tridionGeneration.client.GetDefaultData(ItemType.Component, tridionGeneration.Settings.ComponentFolderUri);
if (schemaFields.Fields != null)
{
var fields = Fields.ForContentOf(schemaFields);
Helper.FillSchemaFields(tridionGeneration, fields);
componentData.Content = fields.ToString();
}
if (schemaFields.MetadataFields != null)
{
var metafields = Fields.ForMetadataOf(schemaFields, componentData);
Helper.FillSchemaFields(tridionGeneration, metafields);
componentData.Metadata = metafields.ToString();
}
componentData.Title = (objectCount == 0) ? componentName : componentName + " " + (objectCount + 1).ToString();
componentData.ComponentType = ComponentType.Multimedia;
StreamUpload2010Client streamClient = new StreamUpload2010Client();
FileStream objfilestream = new FileStream(#"[IMAGE_PATH]", FileMode.Open, FileAccess.Read);
string tempLocation = streamClient.UploadBinaryContent("images.jpg", objfilestream);
BinaryContentData binaryContent = new BinaryContentData();
binaryContent.UploadFromFile = tempLocation;
binaryContent.Filename = "[IMAGE_NAME]";
componentData.BinaryContent = binaryContent;
binaryContent.MultimediaType = new LinkToMultimediaTypeData()
{

Can you try this?
