Java command line

Hi,

does Anyone know how to execute a command line command from within java code?

I am using windows N.T. and i would like to execute a command from a Java program.


Thanks.

See the docs for the class Runtime. The exec() method is probably what you

are looking for

Hi,

Thanks for replaying to my message i have used the following :



String classPath = "d:\\javastar\\javastar.zip;f:\\bkw1\\lib\\rescue.zip;c:

\jdk1.1.6\\lib\\classes.zip;F:\\bkw1\\source\\classes;d:

\\jdk\\lib;d:\swingall\\swingall.jar ";

Runtime comp = Runtime.getRuntime();

comp.exec("javac -classpath "+classPath+" "+filename);



but it seems that nothing happens when i run the program!!!!!!!.



what i want is to have:

javac -classpath d:\\javastar\\javastar.zip;f:\\bkw1\\lib\\rescue.zip;c:

\\jdk1.1.6\\lib\\classes.zip;F:\\bkw1\\source\\classes;d:

\\jdk\\lib;d:\\swingall\\swingall.jar filename

executed at the command prompt.



thanks.

Try the foll. if you are working in windows os.

comp.exec("cmd /c javac -classpath "+classPath+" "+filename");

but how to give the input from one process to another process started by a java program.

Hi,

Recently, I posted this:

You can easily couple an output stream of one process to an output stream of another process using the information in this post.
