Recently i created a Penalization calculator which is written in Perl [.exe] language to calculate panel required to manufacture a printed circuited board. I did it for one of our customers. The output screen for this calculator looks like below: I wanted to integrate the same penalization calculator in one of the projects which is written in java. So I code like mentioned below to call exe in java. package panelcalculator; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; public class PanelCalculator { public String calculate(String strParms) { String result = “”; try { Runtime runtime = Runtime.getRuntime(); Process process = runtime.exec(strParms); InputStream inStream = process.getInputStream(); BufferedReader reader = new BufferedReader(new InputStreamReader(inStream)); String data = “”; while ((data = reader.readLine()) != null) { result += data + ” “; } reader.close(); inStream.close(); process.destroy(); } catch (Exception e) { result = e.toString(); } return result.trim(); } public static void main(String arg[]) { PanelCalculator pc = new PanelCalculator(); String result = pc.calculate(“D:\\MyWebapp\\PanelizationCalculator\\PanelCalculator.exe PanelX=12 PanelY=18 NLayers=2 Spec=\”IPC-6012 Class 2\” BoardX=12 BoardY=2.25 Spacing=0.2 LaserDrill=N Flex=N Impedance=N ImpSingleEnd=0 ImpDiff=0 EdgePlating=N”); if(result!=null){ System.out.println(result); } } } And finally i got output like following, exactly the same as I wanted: UsableX=10.2 UsableY=14.6 MaxUp=4 Thank you.
