How to encrypt file on linux using Gnupg command in Java Embedding in BPEL.

Question

Hi All,
I am trying to invoke a command script using the java embedding in BPEL Process.I am using the below code to execute the particular command to encrypt the file :-
try {    
        Runtime rt = Runtime.getRuntime();    
Process pr = rt.exec(new String[] {"/bin/bash", "-c", "/u01/GnuPG/bin/gpg", "-e", "-r", "Developer","/u01/oracle/ConfigFiles/Adapter_controlDir/abc.csv"});    
         int exitVal = pr.waitFor();            
        String result = "SUCCESS: Process exit with " + exitVal;         
        addAuditTrailEntry("result = "+result);      
        setVariableData("outputVariable","payload","/client:processResponse/client:result",result);    
} catch(Exception e) {    
        e.printStackTrace();      
  String result = "FAILURE: Exception with " + e.toString();    
        addAuditTrailEntry("result = "+result);      
        setVariableData("outputVariable","payload","/client:processResponse/client:result",result);    
The above statement does nothing. I am not sure what command i need to use to access to the command line.
When i try this particular statement from linux machine command prompt :- /u01/GnuPG/bin/gpg -e  -r  Developer /u01/oracle/ConfigFiles/Adapter_controlDir/abc.csv
It works absolutely fine and it creates the encrypted files also.
Please suggest , which command i need to use from the java embedding.
Please suggest!!

I think, you can try, writing these commands into a separate shell script and call that shell script from bpel via Java embedding. However, you might not get a return response.. but you can still give a shot.
Hope it helps.
