IOException--CreateProcess HELP!!!

Question

Hi every body.
Does someone know the meaning of this error?
java.io.IOException: CreateProcess: prueba error=2
at java.lang.Win32Process.create(Native Method)
at java.lang.Win32Process.<init>(Win32Process.java:63)
at java.lang.Runtime.execInternal(Native Method)
at java.lang.Runtime.exec(Runtime.java:566)
at java.lang.Runtime.exec(Runtime.java:428)
at java.lang.Runtime.exec(Runtime.java:364)
at java.lang.Runtime.exec(Runtime.java:326)
at org.apache.jsp.ChangeDirBajaRCXX_jsp._jspService(ChangeDirBaja
p.java:185)....................................
It's the result of this code:
cmd="prueba.bat";
exec(cmd);
and the prueba.bat is really simple:
@echo off
lejos HelloWorld
'lejos' is an exe file.
If i try 'lejos HelloWorld' from the MS-DOS it runs ok.
Thanks!!

Hi,
I'm facing the same problem. The only diference is that I need to execute only 1 command but because I have to execute it in a Network folder (that comes from a database, so it is configurable). I tried to enable the UNC support from the Command Shell of Windows XP but without success.
Now I'm trying to use the pushd popd commands so that I can execute my command remotely.
Here is the commands I'm trying to execute (that works with the command):
pushd \\brserver\transaction && try.bat && popd
When I execute that in the CMD, it works but with the Runtime.exec, it gives me the IOException error.
Here is my code:
String command = "pushd \\brserver\transaction && try.bat && popd";
Process process - Runtime.getRuntime().exec(command);
I've also tried that:
String[] commands = new String[]{"pushd \\brserver\transaction", "try.bat", "popd"};
Process process - Runtime.getRuntime().exec(commands);
But without success. If I could only make the UNC works, it would probably resolve my problem.
Is somebody can help me please?
Thanks,
