Linux net command showing incorrect output if executing from java.

Question

I am trying to execute a net rpc registry on red hat linux box from java using Runtime. I have stored the command in a String variable. When the execute the command from java it throws an error saying that "Invalid registry path" however the same command works fine when executed from linux command terminal.
CODE
import java.io.*;
public class ChkBpower {
     public static void main(String[] args) {
     checkBpower(128);
     public static void checkBpower (int TTL){
          int ttl = TTL;
          System.out.println("Hello3");
          String ip = "20.198.36.28";
          String[] reg={"\\","HKLM","\\","SOFTWARE","\\","Marimba"};
          System.out.println(reg);
          String credentials ="bpwrlab/Administrator%Confmgmt1";//"asiapac/gjagdeosingh%M@nu2281";
          String chkBcmd = "net rpc registry enumerate '\\HKLM\\SOFTWARE\\Marimba' -I " + ip + " -U " + credentials ;
          String chkBstatus = "net rpc service status cscmarimba -I " + ip + " -U " + credentials + "| grep -b 'service' | awk '{print $4}'";
          String startBpower = "net rpc service start cscmarimba -I " + ip + " -U " + credentials;
          if (ttl>=100 && ttl<=128){
          System.out.println(ttl);     
          System.out.println(chkBcmd);
          try {
               Runtime r = Runtime.getRuntime();
               Process p = r.exec(chkBcmd);
               InputStream stderr = p.getErrorStream();
     InputStreamReader isr = new InputStreamReader(stderr);
     BufferedReader br = new BufferedReader(isr);
     String line = null;
     System.out.println("<ERROR>");
     System.out.println(br.readLine());
     while ( (line = br.readLine()) != null)
     System.out.println(line);
          System.out.println("</ERROR>");
          int exitVal = p.waitFor();
          System.out.println("Process exitValue: " + exitVal);
          catch (Throwable t)
     t.printStackTrace();
}

Use exec(String[]), not exec(String), whenever you have argue,nets. Saves all that mucking around and second-guessing and escaping ...
