Execution of Java Native Process slow in Mac OS X

Hi,
I'm having some performance issues when executing an java native process on Mac OS X. I am developping an application in AIR that searches for people in the ldap of our organisation. It has to be usable both on Mac as on Windows. When I execute my app on windows, the search process takes about 2-3 seconds. However, when I try to execute it on mac, the search process takes about 6-8 seconds. This is a bit to long to make it usable.
Has anybody encountered this problem as well and does anyone know what the problem can be?
Thanks in advance

Hi Ronald,
Have you tried benchmarking your java process without the inclusion of AIR? If so, did you find a difference which points to AIR being a culprit for the performance hit?
I'd be very interested in trying this out. If you could provide me with a sample project that illustrates the slow down on Mac, I'll take a look right away. Please feel free to contact me via private message on the forum or at [email protected] if you'd like to take this offline.
Thanks,
Chris

Native process execution problem in mac os

hi,
     In my flex application i have to get mac serial number as a unique id for each system . On searching i got one terminal command to get serial number. For that i have run terminal command through flex native process. I have set supportedprofile as <supportedProfiles>extendedDesktop desktop</supportedProfiles> in app xml. But when i install and run application on mac terminal is getting opened but command is not executing. I couldn't trace out the problem. I could execute cmd in windows and that worked . Please help me to findout a solution................... The test code is adding below
private var process:NativeProcess
=
new NativeProcess();
protected function windowedapplication1_creationCompleteHandler(event:FlexEvent):void
                // TODO Auto-generated method stub

Hello Aswathy, these days I'm also coding an application which uses AIR NativeProcess and I required to open the MacOS terminal with some parameter/commands. I also eventually turn to the AppleScript, but I considerably new to the AppleScript, yet trying to findout a way to passing parameters (the command argument) to the AppleScript; the appleScript I managed to open but not passing the argument. Can you please help? here's my some probable codes for the application:
My appleScript is:
#!/bin/bash
on run argv
          tell application "Terminal"
                    set currentTab to (do script) & item 1 of argv
          end tell
end run
I've packaged the appleScript as an Application (Contract.app) and here's my Flex code:
var npInfo : NativeProcessStartupInfo = new NativeProcessStartupInfo();
npInfo.executable = new File( "/Applications/Contract.app/Contents/MacOS/applet" );
                              var arg:Vector.<String> = new Vector.<String>;
                                  arg[0]="ssh [email protected]";
                              npInfo.arguments = arg;
                              process = new NativeProcess();
process.start( npInfo );
Can you please help?
Thank you.

Native Process Concerns on Linux and MAC

I have created an AIR application that has a feature to take screenshot of the screen. I have used "senthil.jar" to support screenshot capture.
http://sensaran.wordpress.com/2010/06/04/screen-shot-utility-using-air-2-0/
http://code.google.com/p/dtflex/downloads/detail?name=ScreenShot.rar&can=2&q=#makechanges
Native Process is created and used. I have also created native installers like -
exe for windows
dmg for MAC
rpm for linux
on windows everything works fine.But on linux and MAC one NativeProcess event is dispatched i.e. Event.ACTIVITY. No other event is dispatched.

I haven't tested JWS before JRE 1.4 so I can't recommend you anything if you require JRE 1.3 or before, but if you can install JRE 1.4, specially JRE 1.4.2 or after, JWS works very good on Linux and Windows. In both platforms I use deploy applications using JWS and they all work very good. I have no experience on Mac OS X.
Both platforms obviously require Java preinstalled. Also there is some ways to install Java automatically, this is something that must be done by an administrator as every other software that requieres installation and configuration on every PC. After that step, everything is very simple.
On Linux if you click on a .jnlp file for the first time, at least mozilla ask if you want to save the file or open it, you can select the javaws executable inside your java installation as the program to open this file, mark that that's the action you always want to do with that kind of files, and that's all. Also you can manually register .jnlp files and application/x-java-jnlp-file mime tipe as handled by javaws as the last part of the java installation and this first step will not be necesary.
On Windows the installer automatically register itself as insterested in handling jnlp files, so the previous step for linux is not required.
Hope this helps.

Completely uninstall the Kaspersky software AND MacKeeper. Both aren't necessary and can cause all kinds of issues.
Also check if Paragon and Virtualbox are up to date.

Creating native processes

Hi,
Runing SuSE Linux 8.0, java 1.4.0
I'm trying to create a native shell (I/O dumped into a JTextArea) woith java, the problem is that once I have invoked bash, it somehow manages to work out that its not running in a real console and behaves as if my input was a script. I managed to get bash working properly with command line args, but now when I want to start other interpreters on top of it they too seem to detect they are not in a proper tty.
Is there a way to make native processes behave as if they were run from, say, an xterm?
my code follows:

Slow moving Mac after Yosemite

I have a Macbook pro mid 2009. I loved this computer until I downloaded Yosemite. Now it is very slow. It also gets extremely hot to the touch on the bottom of my computer after just a few mins of running it. I’m close to throwing in the towel and getting a PC. Please Help!

Conversion Error: I/O error while communicating with native process

Hi,
I am trying to use Oracle Outside In Technology Image Export for conversion of images. I am trying to run the example ExportTest that comes with the downloaded SDK.
I get the below error while running the ExportTest example.
Conversion Error: I/O error while communicating with native process .
Am I missing any settings?
Please guide to the right forum if this is not the one for posting queries on Oracle Outside In Technology Image Export.
Thank you.

Hi Revanth,
I am using Image Export 8.3.7 and I am trying to run the java class "ExportTest" that is in the location sdk\samplecode\ExJava\Examples\ExportTest\src of the download.
My input folder has one jpg - puzzle.jpg (this is just a simple jpg), I am trying to convert it to TIFF. ExportTest.java uses the classes in Export.jar . Export.jar is located in the sdk\samplecode\ExJava\Examples\ExportTest . You can see source files of the Export.jar at location sdk\samplecode\ExJava\Java API\src of the download. I am running the 'ExportTest' by providing the arguments (input folder, output folder and ix.cfg - this file comes with the download). So now when I run this class I was getting the error I mentioned in this post. Inorder to find more details about the error I modified the 'Export.java' (at sdk\samplecode\ExJava\Java API\src\com\outsideinsdk) just to printStackTrace when the exception occurs and rebuilt the 'Export.jar' and ran the 'ExportTest.java'.
And below is the stack trace that I got :

Error when running setup: Attach to native process

Hi,
I try to install the oracle iplanet webserver (version 7.0.13) on linux (centos 6.2, 64 bits).
I first installed the compat-libstdc++-33 packages.
After that I installed JRE, this version:
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)
To install the iplanet webserver I first extract the content of the downloaded file (Oracle-iPlanet-Web-Server-7.0.13-linux-x64).
Then I try to run setup with the command ./setup
The error I get is: attach to native process failed.
Any idea what is wrong?
Regards Stefan
Thanks for the help.

Stefan,
I am seeing the same error on Ubuntu 12.04 Precise Pangolin (which is admittedly unsupported). This happened to me once before on an older version of Ubuntu, and as I recall, it was a missing library dependency, but I am not able to locate the fix I came up with at that time.
Interestingly, my existing ws7u12 installation runs fine, I just cannot upgrade to the latest update (15).
I have this software under support, but only on Solaris (I develop on Ubuntu, but deploy to my production Solaris server). In any case, as Ubuntu is not officially supported, opening an SR for this problem would be a waste of time.
I'll continue digging for my old solution and post here if I find it. If you've since discovered the solution, I'd love to hear it.
Thanks,
Bill

Very slow running Mac Mini

Hi,
I'd like to thank all people supporting us (users) in these discussions, and especially the person who helped me restoring my MBP's performance,
I'm requesting once again some help for my Mac Mini which is very very slow.
Mac Mini running OS X Moutain Lion + Apple's Server add-on (a few services are running : file sharing mainly).
Thanks in advance,

Hello Hedi, see how many of these you can answer...
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...
http://support.apple.com/kb/PH7029
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free Disk space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab of Activity Monitor, are there a lot of Pageouts?

Java Plugin not running on Mac OS X browsers

Hi
I have created an applet that runs on any browser on Windows, and runs only as an application on Mac OS X. But when I try to run it as an applet on Mac OS X, it does not run. I have installed the latest Java from apple, and changed the preferences to run 1.6 Java on the browsers.
I get the following error:

Any ideas how I can fix this?
Thanks,
GK

After doing some research, I still cannot fix this problem.
I Build the applet on Mac OS X using netbeans 6.7.1, with Java 6 (64-bit, there is no Java 6 - 32 Bit on Mac OS X)
When I run the applet on safari or firefox on Mac OS X, The console says running on Java 5. (Although the properties have been changed in Mac OS X /Utilities/Java Preferences)
I have been struggling with no end in site, for this issue.
I was able to get the Applet working by reverting to Java 5 and using the Java Swing jar from Java.net. But I still want to be able to just use Java 6 in Mac OS X. (I can't use the GUI Builder in netbeans with the separate swing jar).
ANY HELP please.

Reading native process standard output stream with ProcessBuilder

Hi,
I'd like to launch an native process (windows application) which writes on standard output during its running.
I'd like to view my application output on a JTextArea on my Java frame (Swing). But I do get all process output
on text area only when the process is finished (it takes about 20 seconds to complete). My external process is
launched by using a ProcessBuilder object.
Here is my code snippet with overridden doInBackground() and process() methods of ProcessBuilder class:
@Override
public String doInBackground() {
jbUpgrade.setEnabled(false);
ProcessBuilder pb = new ProcessBuilder();
paramFileName = jtfParameter.getText();
command = "upgrade";
try {
if (!(paramFileName.equals(""))) {
pb.command(command, jtfRBF.getText(), jtfBaseAddress.getText(), "-param", paramFileName);
} else {
pb.command(command, jtfRBF.getText(), jtfBaseAddress.getText());
pb.directory(new File("."));
pb.redirectErrorStream(false);
p = pb.start();
try {
InputStream is = p.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
jtaOutput.setText("");
while ((line = br.readLine()) != null) {
publish(line);
} catch (IOException ex) {
Logger.getLogger(CVUpgradeFrame.class.getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
Logger.getLogger(CVUpgradeFrame.class.getName()).log(Level.SEVERE, null, ex);
jtaOutput.setText("");
jtaOutput.setLineWrap(true);
jtaOutput.append("Cannot execute requested commmad:\n" + pb.command());
jtaOutput.append("\n");
jtaOutput.setLineWrap(false);
return "done";
@Override
protected void process(List<String> line) {
jtaOutput.setLineWrap(true);
Iterator<String> it = line.iterator();
while (it.hasNext()) {
jtaOutput.append(it.next() + newline);
jtaOutput.repaint();
//Make sure the new text is visible, even if there
//was a selection in the text area.
jtaOutput.setCaretPosition(jtaOutput.getDocument().getLength());
How can I get my process output stream updated while it is running and not only when finished?
Thanks,
jluke

1) Read the 4 sections of http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html and implement the recommendations. Although it is concerned with Runtime.exec() the recommendations still apply to Process generated by ProcessBuilder.
2) Read about concurrency in Swing - http://java.sun.com/docs/books/tutorial/uiswing/concurrency/ .
3) Use SwingUtilities.invokeLater() to update your GUI.

How to set the Native Process Installer generatedFile.exe's icon

hi
i have made the (Native Process packaged) .exe by using adt command
how can i change the default icon to the desiered one
thanks,
Dhaivat

Ah I see what you mean now. Unfortunately, this isn't available directly through AIR. However, there are third party utilities on Windows that will allow you to modify the icon resources and it should be simple enough on Mac through File Info.
If you'd like to see this functionality added to AIR, I'd like to suggest you add a feature request to our ideas.adobe.com page.
Thanks,
Chris

Running native processes internally

Just like Eclipse runs javaw.exe without the java process appearing in the processes list, and air apps probably do the same with the air runtime.
is it possible to do the same with air apps to run other processes?
for example im thinking of writing a java jar app which mediates a java socket and building a as3 class which simulates the socket class (when actually its just using native process), but i dont want the air app to apear to be running 2 processes.
how can i do this?
thank you
marcidus

are both your variabels called name? in the same scope??

Java Webservice client slow compared to dot net client

we have DotNet webservice which is being called by two clients , one a dotnet client and other a javaclient
The problem is java client is taking longer time in processing the results when compared to dotnet client and affecting the performance greatly , i'm using axis in java
Is there any know issue with axis regarding my situation here.
also the same java client when run on linux platform still longer time to process.
please provide me some pointer here

I would test the general performance difference between the 2 platforms on the same machine.
I have the feeling that Java is generally slower on windows than .NET
Microsoft has their secrets after all.

What is "native resolution" for my mac mini G4?

I'm going to buy a 22" Samsung monitor with 1920 x 1080 resolution specs for the mac mini, PPC G4 model. I realize the resolution can be adjusted on the computer, and I need the refresh rate lower than the specified 154mhz limit for "cohesive" monitors. That aside, I remember a term "native resolution for the Mac" and I'm thinking this is, for comparison sake, where the mac should display to make text on a word processing document look 1:1 life size. Also, it will make 1" of graphics appear on 1" of the screen. Am I correct?
I'm wondering because when I run the Samsung monitor at 1920 x 1080, will I end up with tiny, scaled-down graphics and text? And, if so, will there be an ideal resolution to adjust the monitor to?
Hope I'm not too clueless on this.... I haven't used a large monitor in some time and don't remember where my 19" CRT used to be set!
Thanks much for help!

cocteau3,
You may be confusing native with default. The G3 desktop would default to 640 by 480 if you zapped the PRAM. You then went into monitors and sound to increase the resolution to what ever the monitor would support and the onboard video port would support.
Before the days of multi-sync monitors, the resolution was fixed for each monitor. Until the Mac II, you had a fixed resolution monitor built in. With the introduction of the NUBUS card, you could buy a card with support for a larger display that was also a fixed resolution.
The Mac IIcx had no onboard video. You bought a NUBUS card for what ever monitor size you wanted. The card and monitor usually came together. With the Mac IIci, in an almost identical case, you had an onboard video port plus the option to add up to three nubus video cards. Native for that onboard video port was now based on the maximum number of pixels that could be supported at thousands of colors or millions of colors. If you wanted millions of colors, you had to add more VRAM or reduce the matrix from 1024 by 748 to 640 by 480. Some games had to be at 256 colors because that is how they were programmed. If you wanted 1024 by 768, you had to settle for thousands of colors, or less color depth than millions. It was simply math. How much math could the computer video port handle?
At our store, in 1999, we had a Quadra 950 set up with five displays. The onboard video would only support 640 by 480 if you wanted millions of colors. That was the native size. Increase the image area (or monitor size) and you decreased the image size. By having four NUBUS cards installed, you could have five monitors connected at once. It was very easy to demonstrate that a 20" monitor could display 640 by 480 and have large text - viewable by the visually impared. A second 20" monitor was set for 1152 by 870 and the text was tiny. Also displayed was a 17" multi-sync that could change resolution.
With the advent of muti-resolution monitors, the idea of 'native resolution' has been replaced by 'supported resolutions.' A monitor may have a default setting but if it is multi-sync, there is no such thing as native. Just factory default. Set any size and frequency you like, so long as that frequency is supported.
This is the best historical link I found:
http://www.proaxis.com/~ferris/docs/dpi-monitor.html
Note that 72dpi was convertable to typesetting because of that long forgotten concept of desktop publishing.
Finally, you can have a large display set at 1600 x 1200 to display many windows and have one window zoomed in to show text at 200%. So many variables that native is not as useful as twenty years ago.
