How to execute one java file in another java file

Hi All!
I hava a problem.. I need to validate functionality of one java file in my Junit test case.. so, I need to run that java file in my test file..
How should I start with???? Are there any java API's for that.. I checked 'system' ..but which function will suite that functionality,,I am not sure about..

I need to check the functionality of deletetion which
is done by a java class.. Now I need to check this
functionality..whether it is deleting or not... in my
test case.. so, for that I need to execute that java
file in similar manner as how we normally do it...,
in my test case..So let the test case create a file and have your class delete it. What's there to run?

    Let me guess, you want your web application to run a program on the client and to your surprise that's not working?
    Ain't gonna happen.
    its taking more time to execute .... that's y is there any other option to execute .exe file other than Runtime.getRuntime().exec("filename");Write proper English and you may be taken more seriously.
    1) it's not "taking more time to execute", whatever that's supposed to mean.
    2) there's no other way to execute something. Not that you should every use even that way anyway
    3) whenever you start thinking of executing external programs from Java, start thinking of not using Java in the first place.

  • How to compile and run a .java file from another java program

    hello,
    can any one tell me how to compile and run a *.java* file from another java program which is not in same directory?

    Well a smarter way of implementing this is by using a solution provided by Java Itself.
    If you are using J2SE 6.0+ there is an in built solution provided along with JDK itself and inorder to go ahead with solution the below are set of API which you;d be using it for compiling Java Programs (Files)

    Now once we are done with compilation.In order to run a Specific class all you ought to do is create an object and its specific methods of a specified class included in the CLASSPATH which you can manage it easily by usage little bit reflections.

  • Executing .jar files from another .jar file.

    How would I run one .jar file from another .jar file. and is there anyway to call specific class arguments? Because I have one .jar file that reads a specified file and returns its contents.
    So how would I execute it and specify its arguments and how would I make it return something to the executing jar file?

    Because I have one .jar file that reads
    a specified file and returns its contents. Presumably you have a class that does that, and you have that class stored in a jar. And you want to know how to... um... do something with that class. I say "um..." because normally you don't execute a class, either, you either call its static methods or you create an instance of the class and call its instance methods.
    If you have been writing a whole lot of little classes each of which just has a static main method, then stop doing that. Write real Java classes instead. The tutorial is here:

    How to call a Java Class from another Java Class assuming both in the same Package??

    Hi Smita,
    you just need to create an object of that class,thats it. Then you will be able to execute each and every method.
    e.g.
    you have developed A.java and B.java, both are in same package.
    in implementaion of B.java
    class B
                A obj = new A();
                 //to access A's methods
                 A.method();
                // to access A's variable
                //either
               A.variable= value.
               //or
               A.setvariable() or A.getvariable()

  • Copy one text file to another text file and delete last line

    Hi all wonder if someone can help, i want to be able to copy one text file to another text file and remove the last line of the first text file. So currently i have this method:
    Writer output = null;
             File file = new File("playerData.xml");
             try {
                   output = new BufferedWriter(new FileWriter(file, true));
                   output.write("\t" + "<player>" + "\n");
                   output.write("\t" + "\t" + "<playerName>" + playerName + "</playerName>" + "\n");
                   output.write("\t" + "\t" + "<playerScore>" + pointCount + "</playerScore>" + "\n");
                   output.write("\t" + "\t" + "<playerTime>" + minutes + " minutes " + seconds + " seconds" + "</playerTime>" + "\n");
                   output.write("\t" + "</player>" + "\n");
                   output.write("</indianaTuxPlayer>" + "\n");
                  output.close();
                  System.out.println("Player data saved!");
             catch (IOException e) {
                   e.printStackTrace();
              }However each time the method is run i get the "</indianaTuxPlayer>" line repeated, now when i come to read this in as a java file i get errors becuase its not well formed. So my idea is to copy the original file, remove the last line of that file, so the </indianaTuxPlayer> line and then add this to a new file with the next data saved in it. So i would end up with something like this:
    <?xml version="1.0" encoding="UTF-8"?>
    <indianaTuxPlayers>
         <player>
              <playerName>Default Player</playerName>
              <playerScore>0</playerScore>
              <playerTime>null minutes null seconds</playerTime>
         </player>
         <player>
              <playerName>Default Player</playerName>
              <playerScore>0</playerScore>
              <playerTime>null minutes null seconds</playerTime>
         </player>
         <player>
              <playerName>Default Player</playerName>
              <playerScore>0</playerScore>
              <playerTime>null minutes null seconds</playerTime>
         </player>
    </indianaTuxPlayers>
    However after all day searching the internet and trying ways, i have been unable to get anything working, could anyone give me a hand please?

    I would go the XML route too, but for fun, open a file as a BufferedWriter and do this:
    void copyAllButLastLine(File src, BufferedWriter tgt) throws IOException {
        BufferedReader in = new BufferedReader(new FileReader(src));
        try {
            String previous= in.readLine();
            for (String current = null; (current = in.readLine()) != null; previous=current) {
                tgt.write(previous);
                tgt.newLine();
        } finally {
            in.close();
    }

  • How to execute a jsp instruction from a java class?

    How to execute a jsp instruction from a java class?
    Any help please.
    Thank's

    I'll detail my problem:
    Supposing that I have a jsp file called: start.jsp
    In the start.jsp I instanciated an object called global from the class Global ( for example ).
    Then, I called a custom taglib:
    <ix:mytag/>
    In the suitable tld file: the mytag is defined:
    <tag>
    <tag class>Tag1<.....
    The java file Tag1 has method:
    doStartTag(){
    // here is the problem
    global.doSomeFunctions();
    Okay, the problem is that the object gobal is not defined in the class Tag1. what to do?
    I think that I have to pass the object global as a parameter to the class Tag1. How to do that?
    Actually, the problem was to insert the follwoing in the doStartTag method:
    doStartTag(){
    pageContext.getOut().print("<%= hello world %>");
    The output is <%= hello world %> not hello world.
    Okay, the new problem is how to pass an object as a parameter to a class called from a tld file.
    Any help please.
    Thank's too much

  • How to use one hash table inside another hash table

    Hi everyone,
    Any example of hash table inside another hash table.
    Can one here help me how to write one hash table inside another with repeating keys for the first hash table.
    Thanks,
    kanty.

    Do you mean you want the 'value' entries in a hash table to themselves be hash tables? Easy but this often indicates a design flaw.
    Hashtable<String,<Hashtable<String,Value>> fred = new Hashtable<String,<Hashtable<String,Value>> ();But what do you mean by "with repeating keys for the first hash table"?
    Edited by: sabre150 on Jul 2, 2010 10:11 PM
    Looks like you have already handled the declaration side in your other thread. I suspect you should be writing your own beans that hold the information and these beans would then be stored in a Map. The problem I have is that your description is too vague so I can't be certain.

  • How to map one modbus register to another modbus register in labview?

    How to map one modbus register to another modbus register in labview? For example, let 40001 equal to 30001. Thank you.
    Steven

    Hello Steven,
    Sorry, I was under the impression that you were using the complete Lookout development software (as opposed to just the Lookout Protocol Drivers). You cannot do any development (connections, mapping, etc.) with the Lookout Protocol Drivers (LPD). So, you were right. We have to do this in LabVIEW.
    I ain't sure how exactly the Modicon floats work, but assuming what you're saying is correct, in your LabVIEW VI(s) you would read the DataSocket item corresponding to 40yyy+1 first, and then write this value back to the DataSocket item corresponding to 40xxx. Similarly, you would read the DataSocket item corresponding to 40yyy and then write the value read back to the DataSocket item corresponding to 40xxx+1.
    A tip: I wou
    ld at first make sure I have the OPC communication between LabVIEW and LPD working. Make sure you can read and write to the LPD registers via their DataSocket/OPC equivalents in LabVIEW. You can then implement the mapping as described above.
    Hope this helps,
    Khalid

  • Pages Importing from pages file to another pages file

    Is it possible to Import from a separate pages file to another pages file
    IF so HOW?????

    Tulse, I'm using Pages 2 too. The first thing I'd tried this on had only a simple drop cap in a text box, fixed on page. That didn't copy - or at any rate didn't paste. The text box had been sent back to overlay it with inline spaces to clear the capital. These reproduced, but the capital didn't. Neither did kerning or baseline adjustments, nor my inserted guides for "leading" the text to the same depth on every page
    Also page set-up details were not transferred in this way: i.e., if you change the margins in a template (even the blank one) the margins don't transfer. Logical enough, page set-up belongs to the document, not the section.
    Looking at this again, in the Extreme Newsletter template, imported graphics transferred, and inserted text transferred, but layering and placement information did not. I'd made my own pages by altering this, generally using text boxes or shapes to compose picture pages rather than using those in the template. But the copied and pasted sections were all over the place.
    So it may be the case that if you're copying from a section to a document with identical layout, page set-up & etc. to the one you're copying from, the result will contain most of the content. But the layering, placement on page of fixed objects, etc., would seem to be decidedly iffy.
    I've tried it on title page sections, where the info in fixed text boxes copied, but neither their placement nor relative placement, and (in the newsletter template) with both my own and the provided sections, with no consistent results. If it works in some cases, then that would be handy.
    It's easy enough to try, and undo if it doesn't work.
    But it's certainly no subsitute for being able to insert one Pages document into another; nor even always bits of it. I'd be inclined to conclude that copying and pasting in this way uses something less than the full Pages file format.
    Cheers.
