accessing java files within folders

[Rekha Pande]

Hi...
I have this test2.java file which is accessed using
C:/>cd my/my1/
C:/my/my1>java test2.java 89 89
I'm passing two arguments to the file test2.java
now this is when i'm doing it mannually....!!!
Now the actual thing that i have to do is .. that i have a main file called write_to_file.java...and this file takes parameter from jsp and thses parameters are passed to test2.java
So.. when the test2.file is in the same location as of write_to_file.java ..... in my code i'm executing the cmd line like this
Runtime rt = Runtime.getRuntime();
String cmd = "java test2";
cmd = cmd + " "+ data ; // parameters 89 89
System.out.println(cmd);
Process proc = rt.exec(cmd);
System.out.println("do something");
... now i want to know what do i have to write so that i can access the test2.java if it's under two folders
I have tried writing
String cmd = "my/my1>java test2";
but this doesnot work...infact the it doesnot take it as a command line even .... it just displays the entire string.....
Plz tell me how would i execute the test2.java file from write_to_file.java if test2.java is under other folders...
pls help..
Thank u

How about

Runtime rt = Runtime.getRuntime();
String cmd = "java -classpath C:\my\my1 test2";
cmd = cmd + " "+ data ; // parameters 89 89
System.out.println(cmd);
Process proc = rt.exec(cmd);
System.out.println("do something");
