Trying to compile a .java file from another .java file

Hello,
I'm trying to compile a .java file from another .java file using Runtime.exec...
String c[]=new String[3];
c[0]="cmd.exe"; c[1]="/c" ; c[2]="javac Hello.java";
Process p=Runtime.exec(c);
If anyone can help me in atleast getting the command prompt when Runtime.exec("cmd.exe") is executed...that would be great...I tried out notepad.exe, calc, explorer instead of cmd.exe...all the commands display their respective windows..except cmd.exe...the command prompt doesnt appear...
Please help me ASAP....
Thanks for your help in advance...
Regards.

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)
http://java.sun.com/javase/6/docs/api/javax/tools/package-summary.html
How do i do that ??
Check out the below articles which would help you of how to do that

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.
Hope that might help :)

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:
http://java.sun.com/docs/books/tutorial/java/index.html

How to call a Java class from another java class ??

Hi ..... can somebody plz tell me
How to call a Java Class from another Java Class assuming both in the same Package??
I want to call the entire Java Class (not any specific method only........I want all the functionalities of that class)
Please provide me some slotuions!!
Waiting for some fast replies!!
Regards
Smita Mohanty

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()

Please help with executing a java program from another java program

Hi, I have tried to execute a very simple java program which is printed out "Hello world" from another java gui program when the user click on the "START" button. However, I don't receive any print out on the terminal when they click it. These two programs are being developed in Unix environment. Here is the code that I am trying to use.
Runtime r = Runtime.getRuntime();
r.exec("java HelloWorld");
p.s. HelloWorld is java class of the HelloWorld.java

I think you have to luanch your MS Prompt first before executing the command.

end tag <\/script> is wrong.

How to call inner class method in one java file from another java file?

hello guyz, i m tryin to access an inner class method defined in one class from another class... i m posting the code too wit error. plz help me out.
// test1.java
public class test1
     public test1()
          test t = new test();
     public class test
          test()
          public int geti()
               int i=10;
               return i;
// test2.java
class test2
     public static void main(String[] args)
          test1 t1 = new test1();
          System.out.println(t1.t.i);
i m getting error as
test2.java:7: cannot resolve symbol
symbol : variable t
location: class test1
          System.out.println(t1.t.geti());
^

There are various ways to define and use nested classes. Here is a common pattern. The inner class is private but implements an interface visible to the client. The enclosing class provides a factory method to create instances of the inner class.
interface I {
    void method();
class Outer {
    private String name;
    public Outer(String name) {
        this.name = name;
    public I createInner() {
        return new Inner();
    private class Inner implements I {
        public void method() {
            System.out.format("Enclosing object's name is %s%n", name);
public class Demo {
    public static void main(String[] args) {
        Outer outer = new Outer("Otto");
        I junior = outer.createInner();
        junior.method();
}

Class.forName(driver);
con = DriverManager.getConnection(url + db, "root", "root");
try {
String sql = "Select * from fiberComponents";
st = con.createStatement();
rs = st.executeQuery(sql);
while (rs.next()) {
Object value[] = {"Fiber Components",rs.getString(2) };
list.add(value);
} catch (Exception e) {
System.out.println(e);

DefaultMutableTreeNode node = new DefaultMutableTreeNode(hierarchy[0]);
DefaultMutableTreeNode child;
for (int i = 1; i < hierarchy.length; i++) {
Object nodeSpecifier = hierarchy;
if (nodeSpecifier instanceof Object[]) // Ie node with children
child = processHierarchy((Object[]) nodeSpecifier);
} else {
child = new DefaultMutableTreeNode(nodeSpecifier); // Ie Leaf
node.add(child);
return (node);
The problem is when I run my program two windows open up. The original one with JTree1, and the panel and horizontal splitplane and another window with a new tree component that did get its objects from the database. My question is how do I "replace" the JTree1 with the new tree created from the second java file?
Or additionally, maybe I could set the data for JTree1 from within the second java file?

Another way to do this is to manually place the tags into your code by placing the tag [code] above your pasted code and the tag [code] below your pasted code like so:

Opening a hyperlinked password protected file from another Adobe File

I have a user that has a table of contents pdf file. This file links to other files in the same directory. Originally in XP she would click on the link and a password box would open. She would type in the password and was able to read the file. She has now been replaced with a Windows 7 machine and this is not the case. She is able to open the individual files (without actually knowing the contents) in the directory. The password box will pop up when this occurs. When she tries to access the PDF file from the toc.pdf file she cannot.
Is there some sort of security permission that is not allowing a pdf file to open a hyperlinked password protected PDF file in Windows 7.
She is and has been using Adobe Reader X on both machines.
Thank you.

I think this may have something to do with your dns settings. From a shell type ipconfig /flushdns and try again.

Launching a java application from another java application

Hi,
I'm facing an interesting challenge :-)
Inside a Java application, I want to start another java application.
Possible solutions in my list :
1. Using jakarta commons launcher.
2. Runtime.exec (make the code platform dependent).
3. Starting the main method of the other app by create a new Thread inside the current app
4. I know people did this by calling an ant target from the java application but I don't have
any sample code, I appreciate any sample code for it.
Thanks,
Ali Salehi

That is an iteresting challenge :)Don't be mean; he's polite, done some investigation and taken the trouble to be clear. The question, presumably, is "has anyone got a different solution or a preference as to which of these is the best?"
In which case, my advice would be to say that invoking main in a separate thread is fundamentally different from Runtime.exec() because the former would run in the same JVM. Is this what you want? If one app has the other on its classpath then do they need to be separate apps? Could they be modules of a single app?

Open a PDF file from another PDF file on iPad

Hi,
I made a test with 2 PDF files. In the first PDF file I link it to the another PDF file.
I used Hyperlinks in InDesign but it doesn't work.

I seriously doubt that that's possible.
It's difficult enough to accomplish that on a Mac or PC because the file hierarchy must be maintained or the link will be broken. The iOS operating system seems to have only a rudimentary file system.
I looked through the Help files for the best PDF reader I know, PDF Expert, and saw no reference to supporting that feature.

Killing a Java process from another Java process

Hi
Is there a possible way of sending a SIGINT, SIGKILL, or any other signal from a Java process running in one JVM, to a java process running in a different JVM on the same machine.
I've the signal handlers written in my process and they do respond to singals (e.g. on pressing Ctrl-C) on the console, but i want to write a separate program that sends this signal to the first process.
Any ideas?
Thanks in advance and regards
Kashif

The answer, as always, is that Java can't do operating-system-specific things like that, but you can use JNI to do it. However, if your code created the Java process you want to kill, via Process p = Runtime.getRuntime().exec(...), then you can use p.destroy() to kill it.

Help needed to load a flash file from another flash file

This is a two part question - but I am sure that answering
one will solve the other.
I have a menu.swf file, and if I click on the top button it
should load module1.swf. (Which it does) - however I can see the
menu.swf file underneath the module1.swf file.
The second part of the problem is that when I click on the
top button of menu.swf, I want it to goto a specific location
within module1.swf ( say the 8th page )
If I use loadmovienum ("module1.swf",0) it opens a new window
- instead of replacing menu.swf
any ideas

Use loadMovie() or loadClip (with the MovieClipLoader class)
depending on how much you want to know about/control the load. With
these you can specify a target movieClip for the load.
Not sure what you mean by 'location'. If you're talking
frames, you can use the load's target movieclip as a reference to
the swf and use gotoAndPlay - but you have to make sure the swf is
loaded first.

Calling Java Application from another

How can i call a Java Application from another java App.
eg., If my Java application is called MyApp and i would like call another java application from within it.
One way could be by using "System". I would like to know if there is any other method and is portable.
Thanks in advance.

hi,
it works and not!
if you start an other class with a command like this the 2nd prog/class terminates too if you terminate the caller-class!

Not able to execute one Java program from another one via. exec()

Hi,
I am new to this forum, so I might be asking a very trivial quetion.
My program Ap1 is :
class Ap1
public static void main(String a[]) throws Exception
Runtime rt=Runtime.getRuntime();
Process p=null;
p=rt.exec("javac,Pr.java");
Runtime.getRuntime().exec("javac,Pr.java");
When I run the above program, I get below error at the line 7(bold one):
D:\batchwe>javac Ap1.java

I am just wondering how to call one Java program from another one?!
Please help.
thanks
Rashmi

Hi diptaPB,
Thanks for your suggestion.
Here is how I tried it again, but not getting the desired output:
Class Pr looks like below -->
class Pr
public static void main(String a[])
System.out.println("hi from process");
When I run 'Pr' from command prompt, i get the desired output:
D:\batchwe>java Pr
hi from process
However, when I call 'Pr' from another program Ap2.java, it seems that it does not call 'Pr':
class Ap2
public static void main(String a[]) throws Exception
Runtime rt=Runtime.getRuntime();
Process p=null;
String[] cmd=new String[2];
cmd[0]="javac";
cmd[1]="Pr.java";
p=rt.exec("cmd");
D:\batchwe>javac Ap2.java
D:\batchwe>java Ap2
************* no output appears here***********************
Looking forward for your help.

Rashmi
