I used the PLPDF software to generate a blob in PDF format in PL/SQL. I can open it in a browser but I would rather send it directly to a printer from PL/SQL.
I know I can use tools like BI and Jasper but I want this particular solution to be 100% database solution.
I was wondering of I can use JAVA in Oracle to send the blob to a printer.
I've been googling information on how to print a pdf in java, and it seems that the java print api is used more for printing from a swing app. What I'm needing to do is send a pdf document to the printer upon user request. I would like my app to work as follows - User selects pdf to be printed- Program determines pages to be printed and deducts amount from user account- If sufficient money, program sends job to printer automatically without popping up the print screen.- If printed successfully, then program tells user it was printed. I'm able to figure out the rest of the pieces, in regards to user input and determining pages of the pdf, except I don't see how I will be able to print the pdf.
I've tried to use this code
PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
DocPrintJob printerJob = defaultPrintService.createPrintJob();
File pdfFile = new File("c://myPdf.pdf");
SimpleDoc simpleDoc = null;
try {
simpleDoc = new SimpleDoc(pdfFile.toURL(), DocFlavor.URL.AUTOSENSE, null);
[Code] ....
But all that I get is junk characters spread across 15 or so pages, for a pdf file that simply says "Hello World". I can open the pdf file on my computer, and print it ok, but when using the above code, it just prints out junk. How I might need to format or setup the pdf so that I can print it correctly. My program could be run on any number of Linux systems, with a multitude of printer types.
I'm trying to send a text file over a socket, from client to server, but I doesn't work. I will demonstrate a part of the code that isn't working.
The critical part of the server look like this:
while(true) {
try {
Socket socket = fileSocket.accept();
out = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
String s = in.readLine();
And the client like this:
Socket = new Socket(address, number);
BufferedWriter out = new BufferedWriter(new OutputStreamWriter(Socket.getOutputStream()));
BufferedReader in = new BufferedReader(new InputStreamReader(Socket.getInputStream()));
BufferedReader fileIn = new BufferedReader(new FileReader(filename));
String s = fileIn.readLine();
out.write(s);
Now I want the s in the server to hold the same string as s in the client, but the server can't read the stream - nothing happens. I know that readLine() reads until a new line character, but it doesn't word to write and read a single character either.
Show me a code where I can get text file all content to String?
View Replies View RelatedThis is sort of like the last problem I had but it's all about the formatting at the end. I have a file that reads something like:
Name
a bunch of text here
and perhaps a second
or even a third line
I need to output this as:
Name; "a bunch of text here and perhaps a second or even a third line"
Right now I find 'Name' and it outputs:
Namea bunch of text here and perhaps a second or even a third line
How would I add ";" and quotes in the middle? I can imagine that I may need to find name, then skip to the next line and just add name manually as the variable output of the search string.
This is where I am now
public static void main(String[] args) {
boolean output=false;
String name="";
String junk="CHAMBERS";
TextIO.putln("Search for a name");
name = TextIO.getln();
TextIO.readFile("doc.txt");
[Code] .....
So I'm almost there, but those dange double Names are killing me. I tried to add a bit of code where:
if (line.indexOf(name) >= 0){}
I am trying to write to a text file with information stored like this.
brick 500
stone 500
And so on. Here is the code I am using to write to the file.
switch(record){
case "brick":
x.format("%s%n", "brick " + value);
closeFile();
break;
case "log":
x.format("
%s%n", "log " + value);
closeFile();
break;
When I write like this, putting deletes the first line. What I can look into or other functions that would be useful?
I'm working on a simple text editor, and I'm currently saving the contents of my JTextPane in a file using an HTMLEditorKit (text is a JTextPane):
private void save() throws IOException {
int returnVal = fc.showSaveDialog(window);
if (returnVal == JFileChooser.APPROVE_OPTION) {
StyledDocument doc = (StyledDocument)text.getDocument();
HTMLEditorKit kit = new HTMLEditorKit();
BufferedOutputStream out;
[Code] ....
The problem I'm having is that after opening a file that I saved, it does not display (if I disable text/html, it displays the entire html code, but when I re-enable it, nothing displays at all.) Am I loading it wrong, or am I setting the JTextPane's text incorrectly? Or is it, perhaps, another error that I didn't catch?
I'm using JBoss 7.1.1.Final. I'm writing a Spring 3.1.1.RELEASE web application and have a massive amount (~5MB) of text output to send to the browser. I would like the browser to display the output as it is generated, but right now, the browser only displays everything after the servlet's doGet method completes. Here's my method …
@RequestMapping(value = "/mymethod", method = RequestMethod.GET)
public void refreshOrders(final HttpServletResponse response) throws IOException
{
execute(response, myWorker);
}
private void execute(final HttpServletResponse response,

What's wrong ? I'm trying to send parameters in a link so I can get this parameter (an id) and get all the forum-threads that are relatives to this parameter. Because I can't set attributes in a link. Or can I ?

<c:param name="idSub" value="${subforum.idsubforum }"/>
<c:param name="subName" value="${subforum.name }"/>

does not work but I read it's not used in html. I'm really lost on this one.

Using Java 7 update 5 (I know it's old...), we are trying to send concurrent requests to a RMI Server. When we start to tamp up the load (not too much - up to 50 concurrent requests) we start to see many IO Problems like Broken Pipe and Connection Reset By Peer. Could we be hitting some unknown limitation on concurrent access? Is there such limitation?

I have an xhtml file with this content:
<h:inputText tabindex="7" styleClass="input" id="title" value="#{register.title}"
required="true">
</h:inputText>
Basically I want the user to enter his title (e.g. Mr., Dr.), which would be passed on to a bean which would send this information to me in email.
I also have a bean called register, along with setters and getters:
private String title;
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
I want to pass this information to a String called body, within the bean:
body = body+"Title: "+this.title+"
";
I would then send the String in an email.

I have a program that reads lines of text, but some of the lines of text aren't applicable and break the program. I'd like to put a letter in front of the lines in the .txt file I want to use, such as a #.
I need to make an if loop that'll check for the first letter on the line being #, and use the line in the program if true and skip if false. I'm guessing a boolean variable would be useful here to be true or false depending on the presence of #, but I don't know how to only read the first letter of each line, how can I do this?
String contentType = fi.getContentType(); gives text/plain when my file is.txt file and gives image/jpeg when my file is .jpeg file but when my file is .jar or .docx it will return application/octet-stream and application/vnd.openxmlformats-officedocument.wordprocessingml.document respictively so what to do to get exact mime type.
