I need a command line in Windows NT

Hello,
I could really use your help. I have this JAVA program and it needs to
call an outside program. I used the following code to do so.

boolean OldC = NUFile.fileExists(Acc + "\\Client.c");
if (OldC == true) {
//String cmdLine6 = "\\\\a1\\scripts\\clientconvert.exe";
doesn't work
String cmdLine6 = "cmd \\\\a1\\scripts\\clientconvert.exe";
try {
Process process = Runtime.getRuntime().exec(cmdLine6);

}
catch (IOException ioe) {
System.out.println(ioe);

This code works fine in 98 with with cmdLine6 set as "start command /c
..."
I know java isn't a scripting language but I really need this program
and it to run in a command line. I actually can't even get a command
prompt, so if I could just get a command line that would help. I've
been all over the net and can't find anything that works.

Thank you.

When you say "Windows NT", do you mean NT 4.0 or an NT-derived OS like
Windows 2000, XP, etc.? I don't believe the Windows NT 4.0 command
shell understood UNC paths.

Sorry I mean NT 4.0...would it work on XP?

Its weird because I also have this in my program

String cmdLine5 = "\\\\a1\\scripts\\licensesign";
try {
Process process = Runtime.getRuntime().exec(cmdLine5);

}
catch (IOException ioe) {
System.out.println(ioe);

and it works fine. Also if I open the task manager and watch it the
processes CMD shows up on Processes tab but doesn't run and doesn't
show up on the Applications tab like its suppost to.

You may have to provide for consuming the Process output streams before
the program will run to completion. See the JavaDocs for Process for
a discussion.

Are you handling STDIN and STDOUT for your command line program? If not
it can hang.

you don't need CMD to exec an exe file. See
