The project was not built since its classpath is incomplete. Cannot find the class

Query on processing a PDF file using Java mapping

Hi All,
i am trying to process a XML and PDF file using Java mapping, it is successful in XML but unable to do for PDF.
below is the code i am using... can any one guide me how to process PDF's..
byte byte1 = 0;
java.io.ByteArrayOutputStream bos = (ByteArrayOutputStream)outputstream;
while((byte1=(byte)inputstream.read())!=-1){
bos.write(byte1);
bos.close();
Thank You,
Madhav

Hi Madhav,
I think instead of going with JAVA mapping you can write a custom adapter module for it.

How to print PDF files using java print API

Hi,
I was goign throw lot of discusion and reading lot of forums related to print pdf files using java api. but nothing seems to be working for me. Can any one tell me how to print pdf files using java api.
Thanks in advance

Mike,
Can't seem to get hold of the example described in your reply below. If you could let us have the URL to get then it would be great.
My GUI application creates a pdf document which I need to print. I want to achieve this using the standard Java class PrinterJob (no 3rd party APIs I'm afraid, commercial restraints etc ..). I had a stab at it using the following code. When executed I get the pretty printer dialog then when I click ok to print, nothing happens!
boolean showPrintDialog=true;
PrinterJob printJob = PrinterJob.getPrinterJob ();
printJob.setJobName ("Contract.pdf");
try {
if (showPrintDialog) {
if (printJob.printDialog()) {
printJob.print();
else
printJob.print ();
} catch (Exception PrintException) {
PrintException.printStackTrace();
Thank you and a happy new year.
Cheers,
Chris

How to read a text file using Java

Guys,
Good day!
Please help me how to read a text file using Java and create/convert that text file into XML.
Thanks and God Bless.
Regards,
I-Talk

     public void fileRead(){
             File aFile =new File("myFile.txt");
         BufferedReader input = null;
         try {
           input = new BufferedReader( new FileReader(aFile) );
           String line = null;
           while (( line = input.readLine()) != null){
         catch (FileNotFoundException ex) {
           ex.printStackTrace();
         catch (IOException ex){
           ex.printStackTrace();
     }This code is to read a text file. But there is no such thing that will convert your text file to xml file. You have to have a defined XML format. Then you can read your data from text files and insert them inside your xml text. Or you may like to read xml tags from text files and insert your own data. The file format of .txt and .xml is far too different.

How to enable commenting into pdf files using java?

Hi All,
Is there any way available to enable comments into pdf files through java. I have a Adobe Reader 9 and also I want put some comments into pdf file, but the reader is not allowed to place a comment into pdf file before enabling the Comments into pdf. After enabling the comments in pdf file then only we can place the comments and we can the pdf file with comments.
Is there any way available to enable comments into pdf file to view acrobat reader.
Thanks in advance.

The end user who uses the web application has Acrobat installed in their mahcine needs it only for the purpose of enabling comments in pdf. If this task of enabling comments in pdf is done through my application there is no need for acrobat in such user's machine which was requested as a cost cuttnig measure.
For this purpose, i need to know about how to enable comments in pdf through java api.
I have used itext java api for other pdf related manipulation in java. But it does not have feature as per the requirement posted above. Can any body suggest relevant java api to achieve the task requested?
Tahnks in Advance.

How to read from pdf file using VB

I have a PDF file which contains three columns, emp no, designation, contact_info. I have 10 rows in that pdf file. I want to read row by row from the pdf file and write into another text file(tab delimited) using VB.
Could you please help me reading the pdf file?
Thanks,
Arindam

Without reading it in detail, this seems to be automating a save as text function in Acrobat. This will not give you any position information.
If you want position information without writing a plug-in, you need to use the getPageNthWord and getPageNthWordQuads methods in JavaScript.
If you have not already done so, you will need to download the Acrobat SDK which has the documentation you need.
Writing in C# makes even very simple things complicated; if you have a choice, consider VB.

Problems with reading a pdf-file using Safari/Adobe Acrobat Pro

Using Adobe Acrobat Pro 9.5.5. and Safari in Snow Leopard I open the pdf-file of http://dare.uva.nl/document/505726 and small boxes appear in the text f.i. on page 70, 74, on the last page etc.
I don't know why those small boxes appear only on my MacBook Pro with the installed software and others don't read a corrupt text. If I click in den pdf-file on the right side of the mouse and choose "open with Adobe Acrobat Pro" the pdf-file opens correctly (without small boxes)!

As you discovered, Adobe Acrobat/Pro/Reader v.9 will crash for all managed user accounts that store their home folders on the server because it has "difficulty" reading and writing to a folder across a network, which is why it crashes shortly after it launches.
HOWEVER, there is hope. All you need to do is tell Adobe to write all of its files to the local drive rather than the home folder on the sharepoint, as follows:
While logged into your network-user account:
1. Go to the "Shared" folder on the local drive. (Local HD > Users > Shared)
2. Create a new folder named "9.0_x86" if you have an Intel or "9.0_ppc" if you have a PPC (without the quotes for either case). You will have to authenticate as an Administrator.
3. Go to the Acrobat folder within the user's Application Support and delete the folder in it.
(Home > Library > Application Support > Adobe > Acrobat > 9.0_x86 or 9.0_ppc)
4. Open/launch the Terminal application found within the Utilities folder on you Mac.
(Applications > Utilities > Terminal.app)
5. In Terminal, enter the 1st command for Intel or the 2nd for PPC:
ln -s /Users/Shared/9.0_x86 ~/Library/Application \Support/Adobe/Acrobat/9.0_x86
OR
ln -s /Users/Shared/9.0_ppc ~/Library/Application \Support/Adobe/Acrobat/9.0_ppc
Adobe Acrobat 9 should now work properly. You may get the "quit unexpectedly" error message the first time you quit the application, but should only happen the one time.
On a side note, the print spool is slow when printing very large multi-paged PDFs.
This is a fix I found in 2009 by Dennis, can't remember where though.

Can I create MS-Word files or PDF files using java

We are developnig a web based application for banks and in this at some point we need to provide reports to the Banks for downloading and printing . Now I do not want to make simple .txt files ,I wan to use some sophsticated file format which look nice.
So is it possible for the server to create files in say .doc format or in say PDF format etc which the banks may download and print.
I am using java servlets and jsp as front end and java classes in middle tier and oracle is my database.

Please try this code:
import god.java.pdf.*;
PDFWriter pw=new PDFWriter(new OutputFile(new String("sample.pdf")));
pw.print("This is your text.");
pw.close();

Problem reading an xml file using java

i have a Com File which is called through .Net application and i made another java application that call the same COM file using JNI . but the problem is that the xml format generated from the Com file in case of the .Net application is approx 49.9K and the same Xml file Contents generated through java is half the size of the previous file in .net about 24.9K . I had figured out that the .Net application generates the xml file as unicode format while the java application generates the same xml format as ANSI format which is approx the half of the .Net counterpart .
but the problem now is that i can't deserialize the java generated xml to convert it into its java object using XMLDecoder because it is ill formed xml whereas its tags are well structured .
even when i try to open that .NEt xml file into the IE browser it structures the xml file successfully
while the java xml file version tells me that the file is ill formed knowing that the file is well structured and all the tags are valid.

First of, that's not "Unicode" and "ANSI". Those are not really encodings per-se. "Unicode" is sometimes used to refer to UTF-16/UCS-2, and "ANSI" is sometimes used to refer to whatever the current 1-byte encoding of the machine is. But again: Those are not valid encoding names. The encodings used are probably UTF-16 (or UCS-2) and UTF-8, respectively.
Next: unless you tell us some exact error message we can't tell you what went wrong.
And if you want to find out if any given XML file is valid, just run it through some validator (such as [the one from the W3C|http://validator.w3.org/]).
