Re: Making an application "active" from java - Part 2

The AppleEvent accepting stuff needs to be set correctly as well I think. You should should have a unique creator, correctly set plist and at least last I checked for some reason still need a correctly set PkgInfo file as well, in appedit java terms...

 

   String type = new String(buffer,0,4);
   String plisttype = (String)plist.get("CFBundlePackageType");
   String creator = new String(buffer,4,4);
   String plistcreator = (String)plist.get("CFBundleSignature");
   if (!type.equals(plisttype) && !creator.equals(plistcreator))
    System.out.println("PkgInfo out of sync with plist - PkgInfo[" + type + "," + creator + "] , Info.plist[" + plisttype + "," + plistcreator + "]");
   else if (!type.equals(plisttype))
    System.out.println("PkgInfo out of sync with plist - PkgInfo type is " + type + " Info.plist CFBundlePackageType is " + plisttype);
   else if (!creator.equals(plistcreator))
    System.out.println("PkgInfo out of sync with plist - PkgInfo signature is " + creator + " Info.plist CFBundleSignature " + plistcreator);
   else System.out.println("PkgInfo present [" + type + "," + creator + "] - OK");

 

With a uniquely named executable, unique creator, PkgInfo right, and all plist properties set correctly, you should see your process running under it's unique non-JavaApplicationStub name. Incidentally you can of course check that from java using JNIDirect.

 

import macnative.jnidirect.struct.ProcessSerialNumberStruct;
import macnative.jnidirect.struct.ProcessInfoRecStruct;
import macnative.jnidirect.files.FSSpec;
import macnative.jnidirect.string.Str31;
import macnative.jnidirect.functions.ProcessFunctions;
import jnidirect.macnative.OSType;
import utillib.logging.Logger;
import utillib.logging.LoggerInterface;

 

public class mps {
 public static final LoggerInterface logger = Logger.getInstance("roor.org.cmd");
 private static final short noErr = 0;
 private static final short procNotFound = (short)-600;
 public static void main(String [] args) {
  ProcessSerialNumberStruct psn = new ProcessSerialNumberStruct();
  ProcessInfoRecStruct info = new ProcessInfoRecStruct();
  info.setProcessInfoLength(ProcessInfoRecStruct.sizeOfProcessInfoRec);
  Str31 name = new Str31();
  FSSpec appspec = new FSSpec();
  info.setProcessName(name.getPointer());
  info.setProcessAppSpec(appspec.getPointer());
  short err = noErr;
  for (;;) {
   err = ProcessFunctions.GetNextProcess(psn.getPointer());
   if (err == procNotFound) break;
   if (err != 0)
    logger.error("mps: error getting process. err: " + err);
   else {
    err = ProcessFunctions.GetProcessInformation(psn.getPointer(),info.getPointer());
    if (err == noErr) {
     String signature = new OSType(info.getProcessSignature()).toString();
     String procname = name.toString();
     String path = appspec.fullPath();
     int[] pid = new int[1];
     int status = ProcessFunctions.GetProcessPID(psn.getPointer(),pid);
     System.out.println("Name: " + procname + " Signature: " + signature + " pid(" + pid[0] + ") path " + path);
    }
    else logger.error("mps: error getting process info. err - " + err + ". continuing...");
   }
  }
 }
}

 

which I'll leave as an exercise for those interested to convert to normal JNI if they wish. Although why not just use or add to all the neat JNIDirect I have for this? I don't know. Anyhow some blasts from the past on my stuff. Good times.
