Java Programming

Hi Gurus,

i am using NETBEANS IDE 7.2.

i am developing a project that interacts with databases 10g and COM ports of machine , these all processes are performed by .bat file which i am trying to run from jFramform , code works perfectly .bat file is also called perfectly when i run the project using F6 from the NETBEANS, for testing i placed some dialogue boxes on the form to test it ,

but when i run executable .jar  file , form run successfully and dialogue box works perfectly but .bat file is not called by executable .jar file.

this is how i call the .bat file...

  String filePath = "D:/pms/Libraries/portlib.bat";   
        try {  
          Process p = Runtime.getRuntime().exec(filePath);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }   

  

and below is the contents of portlib.bat file

--------------------------------------------------------------------

you must probably ask why i am calling a .jar file using .bat file .

reason is that this .jar project sends message using GSM mobile , System.exit(); is compulsory to complete a job and then do the next one ,

if i use the same file to execute this job it makes exit to entire the application (hope you can understand my logic).

that's why i use extra .jar file in .bat file , when single job is completed .bat exits itself and new command is given.

Problem is that code is working perfectly in NETBEANS when i run the project but when i run .jar then .bat file is not working  ,

thanks.
