Invoking Acrobat PDF compare from Java code

Need to invoke the Adobe Acrobat XI's PDF compare feature using Java code.
Description:
========
We are exploring the possibilities of passing 2 PDF's from Java to Adobe Acrobat XI SDK to get the compared results in new PDF.
If anyone has explored with this feature... please share your thoughts.

You would need to write a custom plugin to Acrobat that calls the compare APIs (as they are only accessible from C/C++).  Your plugin can then expose whatever from of IAC/IPC that it wishes to communicate with your Java code.
Of course, this is all DESKTOP code since Acrobat can't be used on a server.

  • How do I invoke another s/w from java code(urgent)

    Hi all,
    My code looks like this :
    Runtime rt =Runtime.getRuntime();
    String command = "~/tts/bin/mbrola" +" ~/tts/mbrola/us2 " + " /home/dir1/dir2/final/temp.pho "+
    " - | ~/tts/bin/mbrplay -";
    rt.exec(command );
    Whenever I ru n this code thru java , I get an error that this command was not found but am able to run it in my unix terminal. Would anyone have any clue as to why this is happening.
    Thanks

    Thanks
    SohiniHi,
    I guess that you're trying to run command WITH arguments, aren't you?
    So, you have to do it this way(just verify arguments):
        Runtime rt =Runtime.getRuntime();
        String command[] = {"~/tts/bin/mbrola", "la", "~/tts/mbrola/us2",
                                              "/home/dir1/dir2/final/temp.pho",  "-", " | ~/tts/bin/mbrplay", "-"}
        rt.exec(command);(making PROGRAM and ARGUMENTS an array - EACH argument SEPARATELY(I don't know their exact number in your script ))
    Hope to help,

  • Invoking a bash shell script from Java code

    Hi All
    I am trying to invoke a Bash shell script using java code. The arguments required are "source wmGenPatch <source dir> <destination dir> no_reverse.
    in the code I have specified the arguments considering the cannonical paths of the files as the code may run on Unix or windows platform.
    I am getting a error while invoking Runtime.getRuntime().exec(args). The error is as follows :
    "The Error Occurred is: CreateProcess: source D:\Package4.0\workspace\DiffEngineScripts\v4a02\wmGenPatch D:\Package4.0\workspace\fromImageFilesDir\ D:\Package4.0\workspace\toImageFilesDir\ no_reverse error=2"
    It seems that error=2 indicates that the 'file not found' exception. But i can see the directories referred to in the error at place in the workspace.
    Kindly advice.
    Thanks in advance.

    Dear colleagues,
    I'm facing a error at execution time when I'm invoking a BPEL process from java. My BPEL process is in a different server than my application.

    Hi
    You are trying to create a locator object with default values which does not work at all times.Use Locator("default",prop) where prop is a properties object and set the values according to your environment.
    The following properties values must be set
    Properties props=new Properties();
    props.setProperty("orabpel.platform","ias_10g");
    props.setProperty("java.naming.factory.initial","com.evermind.server.rmi.RMIInitialContextFactory");
    props.setProperty("java.naming.provider.url", "url value");
    props.setProperty("java.naming.security.principal","domain user name");
    props.setProperty("java.naming.security.credentials","password");
    props.setProperty("dedicated.rmicontext", "true");

  • Problem in printing pdf document with java code

    Hi All
    I want to print a pdf document with java code i have used PDFRenderer.jar to compile my code.
    Code:
    File f = new File("C:/Documents and Settings/123/Desktop/1241422767.pdf");
    FileInputStream fis = new FileInputStream(f);
    FileChannel fc = fis.getChannel();
    ByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
    PDFFile pdfFile = new PDFFile(bb); // Create PDF Print Page
    PDFPrintPage pages = new PDFPrintPage(pdfFile);
    // Create Print Job
    PrinterJob pjob = PrinterJob.getPrinterJob();
    PageFormat pf = PrinterJob.getPrinterJob().defaultPage();
    pjob.setJobName(f.getName());
    Book book = new Book();
    book.append(pages, pf, pdfFile.getNumPages());
    pjob.setPageable(book);
    // System.out.println(pjob.getPrintService());
    // Send print job to default printer
    pjob.print();
    but when i am running my program i am getting error
    Exception in thread "main" java.awt.print.PrinterException: Invalid name of PrintService.
    Please anybody, knows the solution for this error?
    Thanks In Advance
    Indira

    It seems that either there is no default printer setup or you have too many printers or no printer setup at all. Try running the following code. It should print the list of available print services.
    import java.awt.print.*;
    import javax.print.*;
    public class PrintServiceNames{

  • Invoke a command-line from java

    Hello!
    I wonder if there' s a way to invoke a command or running an .exe file from java code.
    10X,
    Yaron

    Sure, using the exec method in the class Runtime. You have to be careful with it though...

    Did you ever find a solution to your problem?
    My situation is that I'm running a process that grabs data from a salesforce.com web service and dumps some of the data back into my local database. The process croaks after processing 850 or so records. I have also increased my PermSize memory to 512M.
    Any ideas why all of a sudden after processing that many records it would stop working?
    Thanks,

  • Starting exetutable java file from java code

    Hi I was wondering how I can start a executable java file from java code?
    thanks

    Hi Mkaveli,
    Yes, it's possible. If you have a JAR executable, you've just to call the main method of its starter class. For a simple executable class, just call its main method.
    This way :
    SomeStarter.main(null); // if there's no argumentSmall precision : the executable JAR or class must be specified in the classpath of your application.

  • How to modify an existing xml file from java code.

    Hi
    I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
    For example if xml file(studlist.xml) is as below:
    <?xml version="1.0" encoding="UTF-8"?>
    <StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
         <Student>
              <Name>ram</Name>
              <Age>27</Age>
         </Student>
    <Student>
              <Name>sham</Name>
              <Age>26</Age>
         </Student>
    </StudentList>
    Now suppose i have set name to victor using student.setName,
    and set age to 20 using setAge from javacode,
    the new xml file is as follows:
    <?xml version="1.0" encoding="UTF-8"?>
    <StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
         <Student>
              <Name>ram</Name>
              <Age>27</Age>
         </Student>
    <Student>
              <Name>sham</Name>
              <Age>26</Age>
         </Student>
    </StudentList>
    <Student>
              <Name>victor</Name>
              <Age>20</Age>
         </Student>
    As observed this is not a valid xml file.But how can i modify without any errors?

    I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
    Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
    What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
    // gets the root element of the specified file (code not shown)
    Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
    // write a new student element
    Element student = document.createElement("Student");  // creates the new student
    rootElement.appendChild(student); // ***appends it to the root element***
    Element name = document.createElement("Name"); // creates the name element
    name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
    student.appendChild(name); // appends the name to the student
    Element age= document.createElement("Age"); // creates the age element
    age.appendChild(document.createTextNode("26")); // adds the age text to the age element
    student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

  • Firefox freezes when opening an adobe acrobat (PDF) file from any website

    Firefox freezes when opening an adobe acrobat (PDF) file from any website. This only started happening after the latest update of Firefox was installed. Do you have a fix?

    Hi Susan,
    The Adobe plugin in Internet Explorer is a bit different from the one in Firefox, however they're all made by Adobe and they usually come with Adobe Reader.
    When you open a PDF file in Firefox, it "calls" Adobe Reader to help it read the file. In this case, the Adobe Reader takes over, and it is responsible for freezing your browser.
    I suggest you try the last 4 solutions presented on the [[Opening PDF files within Firefox]] (start with "Re-install the plugin" through "Re-install Adobe Reader").
    Good Luck :D
