Executing UD32 from a Java program

Question

Hi I have Clarify application istalled with Tuxedo6.4. I was able to use UD32 utility
from commandline and execute services in tuxedo. On the Unix (Sun Solaris 2.6)
I am using the following to execute the UD32
$ud32 -U sa<NL>
SRVCNM<TAB>CB_EXESUB<NL>
CLFY_SUB<TAB>ExternalMsg<NL>
EQUIP_ID<TAB>1<NL>
<NL>
however if I use a java program to execute from the same directory, it is not
working. I am obtaining a process from the runtime and writting to the process
to get the above. My code is as follows
import java.io.*;
public class udexec {
public static void main(String args[]) {
try{
Runtime rt = Runtime.getRuntime();
System.out.println("Before");
Process prcs = rt.exec("ud32 -U sa\n");
System.out.println("After: " + prcs);
InputStreamReader isr = new InputStreamReader(prcs.getInputStream());
PrintWriter out = new PrintWriter(prcs.getOutputStream());
out.println("SRVCNM CB_EXESUB");
out.println("CLFY_SUB ExternalMsg");
out.println("EQUIPID 1");
out.println("");
int ret = isr.read();
String line;
System.out.println("Before Print");
System.out.println(ret);
catch (Exception e) { System.out.println(e); }
Any help will be greatly appreciated.
Thank You

No actually I am not getting any error messages. If I use from Command line, I
can see the output in one of the stdout files. In tha case of java I am not getting
any. I think after the first line (ud32 -U sa), writing to the process in java
is not working. Atleast thats what I am thinking.

Raju,
In what way is it failing? Is there any error writtem to stderr of the
ud process, or to
the ULOG?
