How to invoke the compiler from another program

Hi guys,
Suppose I have a source code located in the file MyClass.java.
Now suppose I'm running another program, and in this program I want to compile the MyClass.java file and create the MyClass.class file. Is there a way of doing it through the standard API?
Thanks.

I believe Java 1.6 has a Compiler class as a part of it's "standard" API. Before that, you've got a package called tools.jar in your SDK directory, which is a Java gateway to the compiler

  • .How to instantiate the innerclass from another class with coded eg.

    How to instantiate the innerclass from another class(both for static & non static) please give me an eg with coding.

    It's just a preference, but I like writing factory methods:
    public class Outer {
        public class Inner {}
        public static class StaticInner {}
        public Inner innerInstance() {
            return new Inner();
        public static StaticInner staticInnerInstance() {
            return new StaticInner();
        public static void main(String[] args) {
            Outer.StaticInner si = Outer.staticInnerInstance();
            Outer outer = new Outer();
            Outer.Inner i = outer.innerInstance();
    }Often, for me, the inner class implements an interface, and the factory method
    lets you hide the implementation class:
    public class Outer {
        private class Inner implements Runnable {
            public void run() {}
        public Runnable runnerInstance() {
            return new Inner();
        public static void main(String[] args) {
            Outer outer = new Outer();
            Runnable r = outer.runnerInstance();
    }

  • Variable type Hierarchy, how to get the value from another similar variable

    Hi.
    We have created a variable, type hierarchy (using ORGEH hierarchy in HR based on 0ORGUNIT). Let's call this VAR1. We want to fill this with an User Exit, beacuse we want VAR1 to have the value from another variable, VAR2, which is also type hierarchy (and based on the same characteristic).
    However, when we program this user exit and use the VAR1 afterwards, it just behaves as if we have a single characteristic value and not a node value. As a result, we just get posts which do have the 'parent itself' as characteristic value, and none of the subnodes...  Any hints as to what we can do in our User exit to get the value passed over from VAR2 to VAR1 as a node value? Is there any spesific syntax to be used here that we are missing? ( The VAR1 and VAR2 are both defined as hierarchy variables, we have double checked...).

    Hi,
    are you on BI7.0? There you can create variables type replacement path and get the value out from a different variable without any coding.

  • Reading the output from another program.

    I haven't used Java in a good long while so I need someone to point me in the right direction. I have a C program that I call from a command line (windoze boxen) and it spits out some neat data. I can call it from inside a Java program, but how do I then read the output from the calling Java program? I'd just alter the C program, but I lost the source.

    This article explains how to correctly execute another program from your

  • How tom invoke an EJB from another EJB using the sun rmi protocl in Weblogi

    Hi,
    I am particularly new to EJB.
    My scenario is
    client invoking-->EJB-----invoking ----(Either a webService or an EJB)
    in WEBLOGIC
    Is it possible that a call from EJB to another EJB or WebService use Sun's RMI as underlying protocol instead of t3 or IIOP which are used in Weblogic ?
    Would be really a great help if you could provide me some sample on it on weblogic.

    Hi Stefan,
    You don't need to provide the InitialContextFactory for running a standalone client. The following should work just fine:
    Context initial = new InitialContext();
    System.out.println("Looking up ...");
    Object objref = initial.lookup(EJB);  //the lookup name should be a global JNDI name      //and not from the java:comp namespace
    System.out.println("Looked up EJB");The JNDI implementation looks for the jndi.properties file in your classpath. So make sure that you have the appserv-rt.jar from your <server_installation>/lib directory in your classpath.

  • How to capture the output of another program into a File/String

    I needed to capture the output of a dos program in an String/file I tried doing Runtime.getRuntime.exec("ipconfig /all >tmp.txt");
    but still I am unable to capture the output frm the program which I would like to capture in a file or String.Can anyone help

    When you use the Runtime.exec() method, it returns a Process object, that process object has access to the streams; stdout, stdin, and stderr of the application you just executed. what you'll want to monitor is the stdout or stderr streams using the
    p.getInputStream() or p.getErrorStream(), where p = the process object returned via the Runtime.exe() method.

  • Paste is only pasting a text field instead of an image copied to the clipboard from another program like mail or safari?

    The latest version of Keynote only pastes a blank text field after copying an image to the clipboard in other applications like mail or Safari.  The previous version worked fine with copying and pasting images.  Saving the image to a file and then inserting the image file is the only work-a-round I have found so far.

    To place an image on a slide, use Finder to drag and drop the file onto the slide.

  • How to create a variant to a report from another program at run time

    Hi experts,
                   when i am using FM  :  /OSP/REPORT_CREATE_VARIANT to create a report variant from a program then i am getting  an error 'For object /OSP/ERPNR , number range interval 01 does not exist ', how should i avoid it or can any one help me out to create a report variant from another program at run time with the results of the program.so that i can execute the report from here with this variant

    If i understand you,
    - You can use a FM like [RS_CREATE_VARIANT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=rs_create_variant+&adv=false&sortby=cm_rnd_rankvalue] to create a variant and then use it in the [SUBMIT|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096d67543b11d1898e0000e8322d00/frameset.htm] statement USING SELECTION-SET.
    - But you may also use SUBMIT with WITH parameters which doesnt require variant creation and with much less programming efforts.
    - You can mix the two solutions also.
    So what is you actual requirement, also look at some documentation like [ Scheduling a Job: Full-Control Method|http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/096ce5543b11d1898e0000e8322d00/frameset.htm]
