Reposting ! string concatanation not working in java

Question

hi I am using the following code to construct a string and i see that it seems that the correct string is made but the application does not run
if i just cut n paste the same string into command prompt it works fine . please advise :
also note iam costructing string in two way , but using stringbuffer and by using , but both ways dont work.
If the parameter is just one word for example say "Testing" then the shell command works fine which tells me that the string concatanation is not working or embedding some special chars?
public static void main(String args[]) {
String s = null;
// system command to run
String quotes="\"";
String parameter = quotes args[0] quotes;
String cmd = "awtrap -f 10.200.16.17 -h 10.100.10.112 -p 162 -c fdot 1.3.6.1.4.1.791.2.9.2 6 4 1.3.6.1.4.1.791.2.9.2 -s " parameter;
System.out.println(cmd);
File workDir = new File("/opt/CA/SharedComponents/ccs/atech/services/bin");
StringBuffer sb = new StringBuffer();
sb.append("awtrap -f 10.200.16.17 -h 10.100.10.112 -p 162 -c fdot 1.3.6.1.4.1.791.2.9.2 6 4 1.3.6.1.4.1.791.2.9.2 -s ");
sb.append("\"");
sb.append(args[0]);
sb.append("\"");
String str2 = sb.toString();
System.out.println(str2);
try {
Process p = Runtime.getRuntime().exec(cmd, null, workDir);

I am putting the code in code tags and in preview it shows up perfect, can you see it now ?
import java.io.File;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.InputStream;
public class RunSystemCommand {
public static void main(String args[]) {
String s = null;
// system command to run
String quotes="\"";
String parameter = quotes + args[0] + quotes;
String cmd = "awtrap -f 10.200.16.17 -h 10.100.10.112 -p 162 -c fdot 1.3.6.1.4.1.791.2.9.2  6 4 1.3.6.1.4.1.791.2.9.2 -s " + parameter;
System.out.println(cmd);

StringBuffer sb = new StringBuffer();

sb.append(args[0]);

String str2 = sb.toString();
System.out.println(str2);
try {
Process p = Runtime.getRuntime().exec(cmd, null, workDir);
int i = p.waitFor();
if (i == 0){
BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream()));
// read the output from the command
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
else {
BufferedReader stdErr = new BufferedReader(new InputStreamReader(p.getErrorStream()));
// read the output from the command
while ((s = stdErr.readLine()) != null) {
System.out.println(s);
catch (Exception e) {
System.out.println(e);
{code}
