Set env using a script and run the command (dependency on the env)

Question

I need to set the env varaible by running a shell script with arguments as 'ksh setEnviron r6.1' and then run the command in the
same process. the command has dependency on the previous script which sets the env variables.
With Runtime.getRuntime().exec( cmd1); ,Runtime.getRuntime().exec( cmd2); I am not able to execute the Cmd2 as it is running in different process.
How do solve this issue.
Is there any other method to run the command to set env variables and run the second command.(dependent on the env) to get the output.
Please help me out in this.

Process penv = Runtime.getRuntime().exec("/bin/sh");

BufferedReader stdError = new BufferedReader(new InputStreamReader(penv.getErrorStream()));
final OutputStream writer =  penv.getOutputStream();
for (int i=0; i<commands.length;i++)
     writer.write(commands.getBytes("utf-8"));
     writer.write("\n".getBytes());
String line;
while((line = br.readLine())!=null){
System.out.println(line);
br.close();
writer.close();
I tried the above code but its not working...............
please correct me.
Do you think I used the '-i' argument just for fun? Did you do a 'man sh' and 'man bash' to see what the arguments do? If not then do it now.
Do you think I used Theads to process stderr and stdout just for fun? I've shown you the basic approach. I have shown you how you need to create Threads to process stdout and stderr. If you have not understood and you have not studied http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html then do so now.
