Running shell script from java

Hello All,

Hope all is well. I was trying to scratch my head here with simple problem of running Shell script in Java. I tried to google and look through forums but was unable to understand how to solve it.

Here is my simple Java class, which resides in different directory then my shell script. So I am trying to change path and run the shell script located there. Also, I am passing parameters to shell script from Java as arguments. But for some reasons ...I am getting IOException . Could you please suggest what I am I missing here.


Code:
 
public class test4
{
  public static void main(String [] args) throws IOException
        {
        Process P;
        P = Runtime.getRuntime().exec("cd ~/apps/source");
        P = Runtime.getRuntime().exec("test.sh \"" + args[0]+ "\" \"" + args[1] + "\" \"" + args[2]+"\" \"" + args[3] + "\" \"null\"");
         }
}


Thanks in advance,

Sam
