Need Help with .nnlp File.............A.S.A.P.

I'm having a problem also with my JNLP file. I have downloaded the program onto one computer and that computer is using j2re1.4.2_04
The other computers I believe are all running j2re 1.4.2_05
I'm not sure if that's make a difference, but on the computer with j2re 1.4.2_05 when going to the site where the .jnlp file is located, the application comes up and says Starting Application. After it gets to that screen it just stays there. I really need help with this as soon as possible.
Here is my .jnlp file listed below:
<?xml version="1.0" encoding="utf-8"?>
<jnlp
  spec="1.0+"
  codebase="http://www.appliedsolutions.com/placewiz"

This was due to a change in 1.4.2_05
the main class attribute
main-class="com/asisoftware/placewiz/loader/Exec">is wrong - it should be:
main-class="com.asisoftware.placewiz.loader.Exec">this didnt seem to mater before 1.4.2_05, but some change in java since then caused this bad class specification to stop loading.

  • Need help with connecting file inputs to arrays

    In this assignment I have a program that will do the following: display a list of names inputed by the user in reverse order, display any names that begin with M or m, and display any names with 5 or more letters. This is all done with arrays.
    That was the fun part. The next part requires me to take the names from a Notepad file, them through the arrays and then output them to a second Notepad file.
    Here is the original program: (view in full screen so that the code doesn't get jumbled)
    import java.io.*;       //Imports the Java library
    class progB                    //Defines class
        public static void main (String[] arguments) throws IOException
            BufferedReader keyboard;                                  //<-
            InputStreamReader reader;                                 //  Allows the program to
            reader = new InputStreamReader (System.in);               //  read the the keyboard
            keyboard = new BufferedReader (reader);                  //<-
            String name;                 //Assigns the name variable which will be parsed into...
            int newnames;               //...the integer variable for the amount of names.
            int order = 0;              //The integer variable that will be used to set the array size
            String[] array;             //Dynamic array (empty)
            System.out.println (" How many names do you want to input?");   //This will get the number that will later define the array
            name = keyboard.readLine ();
            newnames = Integer.parseInt (name);                                         // Converts the String into the Integer variable
            array = new String [newnames];                                               //This defines the size of the array
            DataInput Imp = new DataInputStream (System.in);       //Allows data to be input into the array
            String temp;                                       
            int length;                                                                  //Defines the length of the array for a loop later on
                for (order = 0 ; order < newnames ; order++)                                //<-
                {                                                                           //  Takes the inputed names and
                    System.out.println (" Please input name ");                            //  gives them a number according to
                    temp = keyboard.readLine ();                                           //  the order they were inputed in
                    array [order] = temp;                                                  //<-
                for (order = newnames - 1 ; order >= 0 ; order--)                                //<-
                {                                                                                //  Outputs the names in the reverse 
                    System.out.print (" \n ");                                                   //  order that they were inputed
                    System.out.println (" Name " + order + " is " + array [order]);             //<-
                for (order = 0 ; order < newnames ; order++)                                  //<-
                    if (array [order].startsWith ("M") || array [order].startsWith ("m"))     //  Finds and outputs any and all
                    {                                                                         //  names that begin with M or m
                        System.out.print (" \n ");                                            //
                        System.out.println (array [order] + (" starts with M or m"));         //
                    }                                                                         //<-
                for (order = 0 ; order < newnames ; order++)                                            //<-
                    length = array [order].length ();                                                   //
                    if (length >= 5)                                                                    //  Finds and outputs names
                    {                                                                                  //  with 5 or more letters
                        System.out.print (" \n ");                                                      //
                        System.out.println ("Name " + array [order] + " have 5 or more letters ");      //<-
    }The notepad file contains the following names:
    jim
    laruie
    tim
    timothy
    manny
    joseph
    matty
    amanda
    I have tried various methods but the one thing that really gets me is the fact that i can't find a way to connect the names to the arrays. Opening the file with FileInputStream is easy enough but using the names and then outputing them is quite hard. (unless i'm thinking too hard and there really is a simple method)

    By "connect", do you just mean you want to put the names into an array?
    array[0] = "jim"
    array[1] = "laruie"
    and so on?
    That shouldn't be difficult at all, provided you know how to open a file for reading, and how to read a line of text from it. You can just read the line of text, put it in the array position you want, until the file is exhausted. Then open a file for writing, loop through the array, and write a line.
    What part of all that do you need help with?

  • Need help with backup files made by HP Recovery.

    So in 2011 I had made a post about a DV9 series HP laptop I had that I felt needed a harddrive. Well the laptop has been sold to a friend of mine and he has since fixed the issue it had. My curent deboggle is trying to deal with the 36GB of data it backed up onto an external USB powered harddrive. The information was saved from a system that ran Windows VISTA, on that same DV9 Pavilion. I have a new laptop and it's a Pavilion DV6 running windows 7. Is there some sort of 3rd party application or an uncommon HP utility that can open, run or modify. Specificaly I need to some files but not all, but if my only option is to extract all then that would be fine also. There is an executible in the backup folder but it doesn't extract anything it just locks up. 
    For the TLR portion, need to access backup files made on an older HP laptop with windows vista to a newer HP latop running windows 7.

    Terribly sorry for the post, I should have researched more before posting. I found the answer to my issue in another thread here on the HP forums! Thanks so much!!

  • Need help with fla.file

    pls help reopen this file

    create a new directory and move your fla there and try and open.  if that fails, change the file's name and try and reopen.  if that fails and you created the fla, it's probably corrupt.

  • Need Help With Appleworks Files on New Macbook

    Hey Everyone,
    I had an old iMac blueberry with OS 9.2 using appleworks. I just bought a MACBOOK and i got iWORK and MS OFFICE 2004 installed on it. How can i get my appleworks files to open up on my new MACBOOK.
    please help
    -

    will Appleworks transfer and run on an INTEL based
    MAC?
    AppleWorks 6 is a "package" that contains both a Classic (Mac OS 9) application and an OS X application. The rest of what's essential to AppleWorks 6's operation is included in the other items inside the AppleWorks 6 folder. AppleWorks will generate all needed items outside this folder when it is run.
    The OS X application will operate (and operate well) on the intel based Macs using Rosetta, which is included with these machines. AW 6.2.4 and AW 6.2.9 (IN Mac OS 9, the version numbers on the splash screen and in About AppleWorks for these two are 6.2.3 and 6.2.8) are the most stable and least error prone in OS X; update before or after the transfer if you have earlier versions.
    Remember also that your AppleWorks license allows for only one copy to be installed on a computer. If you want to continue to use AppleWorks on the G3 iMac, you'll need to purchase a retail copy to install on the MacBook.

    Barry

    has anyone some experience with this stuff?
    thank you in advance,

    What you try to do involves a lot of parsing, as others have explained already. Parsing data is a tedious and time consuming task normally, but Labview fortunately offers quite some functions to assist you. Unfortunately, however, one needs some experience to apply them. I assembled a VI (see attachment) which probably comes close to want you want.
    When you look into its code you will see some of the parsing techniques. Also notice that I tried to bring the string data from the original file into some other, more useful structure. I do not claim to always have chosen the optimum structure.
    Also I did not do any error checking. So I noticed at the end, that some of the data (although contained in the original file) are missing in the summary produced by my VI. The resaon seems to be an inconsistent use of delimiter characters in that file: mostly individual entries are delimited by a series of blank characters, but sometimes an entry is missing (eg. do some of the lines neither contain 'Pass' or 'Fail', but just another blank instead. Since I took a series of consecutive blanks as a delimiter, my counting of entries had to fail.
    Try to get a more consistently created raw-data file, e.g. one where tab characters are used as delimiters. Otherwise the parsing will be unnecessarily complicated.
    Good luck

    You don't need an Event Structure, a simple State Machine would be more appropriate.

  • Need help with saving file for printer

    I am using Acrobat 9. I have a document with four pages. I need to save it in two files-- one file with p. 4 and 1 side by side to print on 11 x 17 paper, and the other file with p. 2 and 3 the same. The person printing does not have Acrobat so the pdf itself has to be formatted this way so they can print it. I can rearrange the pages, delete pages, and so forth, but I cannot get them to display side by side except in a "view" option.
    Thanks for any help.

  • Migrating from iMac CD to MBPC2D - Need Help with the FIle Migration

    I just ordered a refurb 2.4 MacBook Pro, which will replace my iMac Core Duo as my main machine. The iMac is running Tiger. I've decided that I only am concerned with migrating the following information from the iMac, and want some help on the best way to do this (paths/locations would be helpful too):
    -iPhone backups - to ensure my iPhone doesn't get wiped when it syncs. I will want to copy the last backup over to the MBP.
    -All iTunes Music and Movies
    I will then manually re-install VirusBarrier x4, MS Office, etc. I think this is better than trying to migrate everything over. What do you think?
    Edit: I also have a FireWire external hard-drive available to assist with this.
    Thanks

  • Deploying EJB EARs to Weblogic -- need help with descriptor file?

    I posted this in a different area... maybe it will help to post here.
    Hi all...
    Can someone give me a hand with getting the descriptor correct? I find lots of information about the structure of the XML file, but not much on what needs to go in it.
    If I deploy with it i the default state I don't get that error... but I can't dig my beans out with JNDI.

  • Need help with simple file sharing application

    I have an assignment to build a Java File Sharing application. Since I'm relatively new to programming, this is not gonna be an easy task for me.
    Therefore I was wondering if there are people willing to help me in the next few days. I will ask questions in this thread, there will be loads of them.
    I already have something done but I'm not nearly halfway finished.
    Is there a code example of a simple file sharing application somewhere? I didn't manage to find it.
    More-less, this is what it needs to contain:
    -client/server communication (almost over)
    -file sending (upload, download)
    -file search function (almost over)
    -GUI of an application.
    GUI is something I will do at the end, hopefully.
    I hope someone will help me. Cheers
    One more thing, I'm not asking for anyone to do my homework. I will only be needing some help in the various steps of building an application.
    As I said code examples are most welcome.
    This is what I have done so far

        Scanner input;
        String fileName;
        public RequestForFile() {
            System.out.println("Type the wanted filename here: ");
            input = new Scanner(System.in);
            fileName = input.nextLine();
            for (User u : UserManager.allTheUsers) {
                for (String str : User.listOfFiles) {
                    if (str.equalsIgnoreCase(fileName))
                        listOfUsersWithFile.add(u.nickname);
        public RequestForFile(String fileName) {
            for (User u : UserManager.allTheUsers) {
                for (String str : User.listOfFiles) {
                    if (str.equalsIgnoreCase(fileName))
                        listOfUsersWithFile.add(u.nickname);
        public static List<String> getAll() {
            for (int i = 0; i < listOfUsersWithFile.size(); i++) {
                //System.out.println("User that has the file: " + listOfUsersWithFile.get(i));
            return listOfUsersWithFile;
    }Now this is the general idea.
    The user logs in with his nickname and ip address. He defines his own shared folder and makes it available for other users that log on to server.
    Now each user has their own list of files from a shared folder. It's an ArrayList.
    User manager class is there to store another list, a list of users that are connected with server.
    When the user is searching for a particular file, he is searching through all the users and their respective files lists. Therefore for each loop inside a for each loop.
    Now the problem is how to connect all that with Client and Server class and put it into one piece.
    GUI should look somewhat like this:

  • Need help with pdf file

    I have the version Adobe Reader XI and I can't open up a pdf attachment.  I tried all the troubleshooting in the help menu but nothing is working.   I have to be able to open up pdf file every day. HELP

    Okay the pdf file has a little (save) at the bottom of the file and when you click on it, it says (save to my computer) When I click on this it does not give me an option of where to put the file it just blinks for a secondlike it saved it somewhere but when I go into my c drive and look I can't find it or when I go into adobe reader I can't find it so I tried right clicking on the save to my computer and got these messages
    open
    Open in tab
    open in new window
    save target as
    Now I have tried all of these and it does the same thing.  Just blinks for a second like it did something but again I can't find the file.  I really would like to just go back to opening the file in my email.  Do you think if I uninstalled Adobe reader X1 and reinstalled another adobe reader that might get me back to what I used to have?  This just happened yesterday and I have the same browser and haven't changed anything on my browser but I did update adobe reader so I was thinking it had something to do with Adobe reader X1.
    If you don't think this will work then go ahead and walk me through saving the pdf file but so far I have not been able to open or save it.
