Is there possible using commands with directory to run a java app?

[David Wong]

Hi, I wanna use a command to run a JAVA application like C/C++, for instance, under the windows comand line I write instructions as below:

c:\>F:\MyVcApplications\test.exe

how can I run a java app like that?

c:\>java F:\MyJavaApplications\Test

I know the implementing as above is impossible. There may be a package can resolve this problem, write a line in JAVA code at head: package myjavaapplications; and run it like java myjavaapplications.Test

But this only resolved a part of the problems. How could I find a certain disk, F:\. Maybe you say just change the directory using cd instruction. But the point is I will implement the things in a program like this:

ProcessBuilder pb = new ProcessBuilder();
pb.command(/*the instructions will be here*/);

I think one way that use cd command in pb.command(), But I really prefer a concise way, this is little diffuse, I won't try it anyway.Please help me.

Thanks and wishes with the best.

You probably can do that; find the article by Michael Daconta entitled "When Runtime.exec() won't" (easy on Google) which explains how to keep the two streams "empty."

For the part of your question about "run it from a command line".
Could an executable jar be a solution??

Or you can package your java code into an EXE-file JSmooth - Java Executable Wrapper

[Ernest Friedman-Hill]

Either (1) use the "-cp" switch to set the class path for the Java executable, or (2) create a batch file in which you run the program, including either the -cp switch or a "set CLASSPATH" command, and run that from your Java program.
