executing shell script from java application
 

hi,i want to know is there any way of executing a shell script from my java application? please help me........

read about method exec() at java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html

quick example how to execute 'ls' command

Runtime.getRuntime().exec("ls -l");

Thank u bartekg.......
i have read the description given for runtime and i've tried executing the program as below:
Public class ExecCMD{
psvm(S a[]){
try{
Runtime r=Runtime.getRuntime();
Process p=r.exec("sh xyz.sh");
}catch(Exception e){
.......
}
}
}
when i run this code i didn't get the o/p as the shell should print a string.So,i have changed my shell to redirect the o/p to a file
i.e
xyz.sh: echo "abcdef" > abc.txt
so after running the above java program i got a file named abc.txt which contains the string abcdef.this shows that my shell is running.
But what my problem is, i must give input from an interface created by java
program to a shell script.(dynamically)
i' m very thankful to u
plz reply me soon

One way to do it is to create a file-system pipe (man mkfifo). Have the script read from it, and have the java program write to it.

Another way would be using the Runtime.getInput/Output/ErrorStream() methods.
