Calling nested Batch files from Java

Question

Hi,
I have a java program which loops through a list of batch files, executing each one. This works fine. My problem is that each batch file I execute contains a call to execute a further batch file.
The second(nested) batch file never gets run. The java program completes sucessfully though. Any ideas of a way around this?
Code:
while (batFileToken.hasMoreTokens()){
    String batFileName = batFileToken.nextToken();
    Process process = load.exec("cmd.exe /c "+batFileName);
    process.waitFor();
}Each batFileName it executes contains the below command:
call test.battest.bat never executes.

the way to make sure process is completed.. is
try{
Process proc = Runtime.getRuntime().exec(optimizer.exe);
StreamGobbler errorGobbler = new StreamGobbler(proc.getErrorStream(), "ERROR");
StreamGobbler outputGobbler = new StreamGobbler(proc.getInputStream(), "OUTPUT");
errorGobbler.start();
outputGobbler.start();
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
catch (IOException ex1) {
System.out.println("Error in Starting Optimizer");
catch (Throwable t) {
t.printStackTrace();
class StreamGobbler extends Thread {
InputStream is;
String type;
OutputStream os;
StreamGobbler(InputStream is, String type) {
this(is, type, null);
StreamGobbler(InputStream is, String type, OutputStream redirect) {
this.is = is;
this.type = type;
this.os = redirect;
public void run() {
try {
PrintWriter pw = null;
if (os != null)
pw = new PrintWriter(os);
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) {
if (pw != null)
pw.println(line);
System.out.println(type + ">" + line);
if (pw != null)
pw.flush();
catch (IOException ioe) {
ioe.printStackTrace();
}
