Hi,
I have written the Java Code for Printing files from my apllication.
If i run this program stand alone, it is printing files as much as are there.
But if i am including this program to my application, its printing onlY 1 file after that it got stopped.

Actually while executing the program, initially socket gets open and it takes the file to print meanwhile it gets the 2nd file to print but at that time that socket is already opened. So coz of that this problem is happening as i think.

Can anybody help me out for the same ?
i have pasted the code for the same which i am using.

I would be very thankful.


Code::


//Method used to print files using printer IP and Port
private boolean printWithIP(String printerIP, String printerPort, String fileName){
boolean printStatus = false;
Socket clientSocket = null;
DataOutputStream outToServer = null;
FileInputStream fin = null;
try{
File file = new File(fileName);
if(fileName.contains("PCL") || fileName.contains("pcl") || fileName.contains("txt") || fileName.contains("TXT")){
Thread.sleep(7000);
clientSocket = new Socket(printerIP.trim(), Integer.parseInt(printerPort.trim()));
outToServer = new DataOutputStream(clientSocket.getOutputStream());
fin = new FileInputStream(file);
byte fileContent[] = new byte[(int)file.length()];
fin.read(fileContent);
outToServer.write(fileContent);
clientSocket.close();
outToServer.close();
fin.close();
printStatus = true;
}else if(fileName.contains("acc") || fileName.contains("ACC")){
Thread.sleep(7000);
clientSocket = new Socket(printerIP.trim(), Integer.parseInt(printerPort.trim()));
outToServer = new DataOutputStream(clientSocket.getOutputStream());
StringBuffer contents = new StringBuffer();
BufferedReader reader = null;
try{
reader = new BufferedReader(new FileReader(file));
String text = null;
// repeat until all lines is read
while ((text = reader.readLine()) != null){
contents.append(text).append("\n");
}
}catch(Exception e){e.printStackTrace();}
System.out.println(contents.toString());
outToServer.writeBytes(contents.toString());
outToServer.close();
printStatus = true;
contents = null;
reader = null;
clientSocket.close();
}else if(fileName.contains("pdf") || fileName.contains("PDF")){
Document document = new Document();
document.open();
PdfReader reader = new PdfReader(fileName);
Map info = reader.getInfo();
String key;
String value;
for (Iterator i = info.keySet().iterator(); i.hasNext();) {
key = (String) i.next();
value = (String) info.get(key);
System.out.println(key + ": " + value);
}
if (reader.getMetadata() == null) {
} else {
System.out.println("XML Metadata: "
+ new String(reader.getMetadata()));
}
// escapade 2
StringBuffer strbufe = new StringBuffer();
byte[] streamBytes = new byte[(int)reader.getFileLength()];
for(int z=1; z<=reader.getNumberOfPages(); z++){
PdfDictionary page = reader.getPageN(z);
PRIndirectReference objectReference = (PRIndirectReference) page.get(PdfName.CONTENTS);
// System.out.println("=== inspecting the stream of page" +z+" in object " +
// objectReference.getNumber() + " ===");
PRStream stream = (PRStream) PdfReader.getPdfObject(objectReference);
streamBytes = PdfReader.getStreamBytes(stream);
PRTokeniser tokenizer = new PRTokeniser(streamBytes);
while (tokenizer.nextToken()) {
if (tokenizer.getTokenType() == PRTokeniser.TK_STRING) {
// System.out.println(tokenizer.getStringValue());
strbufe.append(tokenizer.getStringValue());
// System.out.println(strbufe);
}
}
}
Thread.sleep(7000);
clientSocket = new Socket(printerIP.trim(), Integer.parseInt(printerPort.trim()));
outToServer = new DataOutputStream(clientSocket.getOutputStream());
System.out.println(strbufe.toString());
outToServer.writeBytes(strbufe.toString());
outToServer.close();
clientSocket.close();
printStatus = true;
document.close();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally{

try {
clientSocket.close();
} catch (IOException e) {
try {
outToServer.close();
fin.close();
clientSocket.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
// TODO Auto-generated catch block
e.printStackTrace();
}
}
return printStatus;
}//printWithIP()

Welcome to JavaRanch.

Please edit your post to UseCodeTags. It's unnecessarily hard to read the code as it is, making it less likely that people will bother to do so.

At a quick glance, it looks as if the sockets get closed after use, so I don't think that's the problem. A few well-placed debug statements will confirm whether that is or is not the case.

What is the difference between "run this program stand alone" and "including this program to my application"?
 
It is sorta covered in the JavaRanch Style Guide.
