How can i generate BARCODE Images using JAVA Code

Hello ,
My requirement is to generate BarCode Images to Print using JAVA Code.
User will give only
1) String.as Input Parameter and
2) Type of Encoding you want to apply on to the String.
outPut : code should generate Bar Code Images as per the requirements.
can any one help me out with jars ????? or any link which can provide me start.

1) I have requriement like generate doc file with
more than one barcode image on that document.???
So?
If your chosen "doc file" format supports inclusion of multiple images there's no problem.
If it doesn't, choose another format.
2) I am able to generate .doc file but in which
format i should open that doc file.????
The same format you used to create it.
3) Main thing is how can i put more than one barcode
image on that doc file????
That would depend on the file format and the API used to create it.
is any one faced the same problem or gone through
same requirement.
Almost certainly. And they solved it too, given the document I'm looking at right now which is an e-ticket for an airline that has many barcodes and other generated images on it.
So keep on trying, grasshopper, and you may find enlightenment.

     >>i want to know how can i install any software

    So what kind of your software?
    In C#,we can install and uninstall "*.msi" files (setup).
    The code to install software without user interface is:
    private void installSoftware()
    Process p = new Process();
    p.StartInfo.FileName = "msiexec.exe";
    p.StartInfo.Arguments = "/i \"C:\\Application.msi\"/qn";
    p.Start();

  • How can i get system variable using java

    Hi,
    I just want to know how can i get system variables using java code.
    for example i want to get the the date for today or i want to get the number of processes that's running.
    Thanks alot

    Hi,
    I just want to know how can i get system variables
    using java code.
    for example i want to get the the date for today or i
    want to get the number of processes that's running.
    Thanks alotSome generic "system variables" are available though Java, usually through the System class.
    Date today = new Date();
    is instantiated with the current date and time.
    Other system values, like environment values, should be passed to java through the command line (-D option) by setting system properties.
    Finally, platform specific values like the number of processes running will have to be written in platform specific code and executed by JNI (java native interface).
    Java is platform or system agnostic. Common system values, like time, are implemented. Hopefully you won't need platform specific values.

    Hi,
        declare a error message in message pool and declare a method say "checkCostCenters " and in this method, u can check whether it is a valid cost center .. if it is invalid cost center , then throw the erro message using the below code :
    wdComponentAPI.getMessageManager().reportContextAttributeMessage(
                        inputfieldattibutePointer, IMessageProgramPlanComp.ur error message,
                        new Object[] );
    for getting pointer and label use the below code:
    IWDAttributePointer inputfieldPointer = URNODEELEMENTElement
                        .getAttributePointer(URNODEELEMENT.ATTRIBUTENAME);
              String inputfieldLabel = wdContext.nodeURVALUENODE.getNodeInfo()

  • How to convert JPEG - PNG images using java?

    Hi,
    Has anyone done this before?
    Can you provide me with a sample code or point me to the direction on how this can be done?
    Are there any existing Java technology that supports this?
    Most grateful. Thanks.

    It's should be easy using Java Advanced Imaging (JAI). Try this.
    import javax.media.jai.JAI;
    import javax.media.jai.RenderedOp;
    public class convert {
      static public void main(String[] args) {
        String inName = args[0];
        String outName = args[1];
        RenderedOp source = JAI.create("fileload", inName);
        JAI.create("filestore", source, outName, "PNG", null);
        System.exit(0);
    }

  • How can I open a program using Java and then perform certain tasks with it?

    For example, and this is just an example, I want to write a Java program that opens MS Paint and then manipulates that program. This can be useful to automate certain tasks.
    My question is whether this can be done writing Java code and if so how? If not possible, would I need to use a scripting language instead?

    write a Java program that opens MS Paint and then
    manipulates that program. This can be useful to
    automate certain tasks."manipulates" is a too wide term. Let me narrow down:
    1. If you want to open (run) the program and then shut (kill) it down it is possible and fairly trivial to do in java. Look up Runtime and Process classes in java.lang package
    2. If you want to open the program and edit some image/document in the opened program. It is very difficult in java. May be possible... using some Java/COM bridge, assuming your native program is COM/Active-x compliant. Note: these things go beyond the boundary of JVM and needs to interact with host OS and involves shared memory, ipc and all "low level" stuffs.
    If you want to be able to play around with these COM/Activex apps- choose .NET instead :-)
    3) You can open the program from java and pass it some command line arg as in (1) above and then the program will load that document/image at startup automatically. You may then edit the doc/image thru that program itself. However, Java is not doing anything for you here, other than just starting off your native mspaint.exe ot notepad.exe.

  • How can I run other programs using java program

    hi experts,
    I am trying to execute a set of commands from java program
    eg: from command prompt
    java CommandExecutor c:\winnt\notepad.exe c:\some.exe c:\onemorecommand.exe
    and inside the CommandExecutor main method..
    public static void main(String []arg)
    for(i = 0; i < arg.length; i++)
    Runtime.getRuntime().exec(arg(i));
    the above code is executing all the command one after the other, but I want to execute the above commands squentially, i.e I want to execute the second command only after finishing the first command and the third after finishing the second and so on depending upon the arguments passed, how can I acheive this...
    I have tried to use the Process which is returned by the exec(arg) method but the exitValue() returns same value before execution and after execution.
    thanks,
    krishna

    Did you try to get the process returned and then try
    process.waitFor() method. This waits for the process to finish.
    After that try the next execution

  • How can I load an applet using Java Plug-in?

    I have written an applet and have tested with appletviewer, but I can't load it from a browser. Ghlin told me that I need to use Java Plug-in to load it. Please tell me how.

    Click on the Products and API link at the top left of this page. Download the Java Plugin. Be sure to get the developers version. Inside that developer's version there is a tool called HTMLConverter. Run HTMLConverter on your HTML and it will modify the applet tag in such a way that if the user already has the Java Plugin then it will use it. IF not, then the user will be asked if he wants to download it.

  • How can I decode Japanese character using java from JavaScript escape() function

    Hi:
    I have an application which supports Japanese character. I am using JavaScript escape() function to encode the text field before I posted it through web server and then I will just convert it into hex number to decode it through an Integer. It works fine for the character between ascii 1-255. However, it faild on all the double bytes character. All the unicode has the format of "%uXXXX" after it is escaped from JavaScript. How can I resolve the decoding problem?
    Thank,
    David

    Please use 'encodeURI()', though it is supported only IE after 5.5.
    I'm not sure Netscape.
    Thanks,

  • How can i grabb some image using an usb video grabber in Labview 7?

    How can i make a list with all video and audio devices?
    How to use DirectShow functions in Labview 7?

    Hi,
    I can help you out with the audio part of your question: the Windows API has a set of functions called waveOutGetNumDevs and waveInGetNumDevs that give you the number of available devices for input or output. Then you can use waveInGetDevCaps and waveOutGetDevCaps to get more information on each device; with some work you could get the manufacturer and formats supported.
    I have very limited knowledge on DirectShow; however it is based on COM so you shold be able to access it with LabVIEW's ActiveX capabilities.
    I hope this helps.

  • How can i add more statements in java code dynamically...

    I have a (business works) BW process in TIBCO which has many activities including �java code�. In java code activity I have some if statements like
    if (Country.equals("USA�))
    Country code = 1
    else if(Country.equals("GERMANY�))
    Country code = 49
    the above information is coming from database. now my project is deployed and running. In future, if they add more countries in database how I can include them dynamically without changing my BW process java code activity and redeploying again. Is there any solution?
    Please advice.

    You won't reconfigure the Java application without redeploying. This is one of the reasons that including data in the code is bad.
    If you created a file which contained data like this:
    Canada <tab> 1
    USA <tab> 12
    Germany <tab> 6
    Then your program could read the file into a map. The map could be used to lookup the country code based on the name.
    In the future, you could change the file to:
    Canada <tab> 1
    USA <tab> 12
    Germany <tab> 6
    France <tab> 17
    China <tab> 2
    And the program wouldn't need to be changed. You would just need to send out the new country file.
