Compile Java to Native?
Hi, I keep hearing people telling me that you can do this But I have never found info about how to do this? Is there such a utility - AFAIK Sun does not provide one? Also what's the performance issue? How can it be tuned? Eugene Teh Berkeley, CA

It's currently my favorite product for doing this. Also, the Open Group (www.opengroup.org) has a product called "TurboJ". TowerJ is 100% native, which TurboJ can mix native/interpreted. TurboJ is a little slower and integrates with a platform's native JDK. Both of these products run on Linux. Symantec's product will compile for Windows. Yippee. -- Charles
Modal dialog bug?
I have some fairly simple code derived from code generated
by JBuilder 2. I've stripped it down to make it easier to
see the problem.
The problem is that JBuilder generated code for an About type
dialog and when I run the code on Linux the dialog window
just flashes on the screen and then disappears. In hunting
for the problem I found I could make the dialog window work
by just commenting out the setModal(true) call. I think the
code should work as it is and did try a slightly older version
on my Windows 95 JDK 1.1.6 and it worked there so it seems to
be Linux specific.
Here are the source code files:
LinuxRetail.java:
import java.awt.*;
import java.util.*;
public class LinuxRetail {
public LinuxRetail() {
LinuxRetailFrame frame = new LinuxRetailFrame();
frame.validate();
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Dimension frameSize = frame.getSize();
if (frameSize.height > screenSize.height)
frameSize.height = screenSize.height;
if (frameSize.width > screenSize.width)
frameSize.width = screenSize.width;
frame.setLocation((screenSize.width - frameSize.width) / 2,
(screenSize.height - frameSize.height) / 2);
frame.setVisible(true);
}
public static void main(String[] args) {
new LinuxRetail();
}
}
LinuxRetailFrame.java:
import java.util.*;
import java.awt.*;
import java.awt.event.*;
public class LinuxRetailFrame extends Frame {
BorderLayout borderLayout1 = new BorderLayout();
MenuBar menuBar1 = new MenuBar();
Menu menuFile = new Menu();
MenuItem menuFileExit = new MenuItem();
Menu menuHelp = new Menu();
MenuItem menuHelpAbout = new MenuItem();
public LinuxRetailFrame() {
try {
jbInit();
}
catch (Exception e) {
e.printStackTrace();
}
}
private void jbInit() throws Exception {
this.setLayout(borderLayout1);
this.setSize(new Dimension(400, 300));
this.setTitle("LinuxRetail");
menuFile.setLabel("File");
menuFileExit.setLabel("Exit");
menuFileExit.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
fileExit_actionPerformed(e);
}
});
menuHelp.setLabel("Help");
menuHelpAbout.setLabel("About");
menuHelpAbout.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
helpAbout_actionPerformed(e);
}
});
menuFile.add(menuFileExit);
menuHelp.add(menuHelpAbout);
menuBar1.add(menuFile);
menuBar1.add(menuHelp);
this.setMenuBar(menuBar1);
}
public void fileExit_actionPerformed(ActionEvent e) {
System.exit(0);
}
public void helpAbout_actionPerformed(ActionEvent e) {
LinuxRetailFrame_AboutBox dlg = new LinuxRetailFrame_AboutBox(this);
dlg.setModal(true);
dlg.show();
}
}
And finally LinuxRetailFrame_AboutBox.java:
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import com.sun.java.swing.*;
public class LinuxRetailFrame_AboutBox extends Dialog implements
ActionListener{
Panel panel1 = new Panel();
JButton button1 = new JButton();
BorderLayout borderLayout1 = new BorderLayout();
public LinuxRetailFrame_AboutBox(Frame parent) {
super(parent);
enableEvents(AWTEvent.WINDOW_EVENT_MASK);
try {
jbInit();
}
catch (Exception e) {
e.printStackTrace();
}
pack();
}
private void jbInit() throws Exception {
this.setTitle("About");
setResizable(false);
panel1.setLayout(borderLayout1);
button1.setText("OK");
button1.addActionListener(this);
panel1.add(button1, BorderLayout.CENTER);
this.add(panel1, null);
}
protected void processWindowEvent(WindowEvent e) {
if (e.getID() == WindowEvent.WINDOW_CLOSING) {
dispose();
}
super.processWindowEvent(e);
}
public void actionPerformed(ActionEvent e) {
if (e.getSource() == button1) {
dispose();
}
}
}
Hopefully someone can help me track this bug down!

Dialog problem
Just an update on the problem with Dialogs: 1. I copied the .class files over to Windows 95 and ran them using the 1.1.6 JDK from Sun and the About dialog box worked there so its definitely a Linux Java bug. 2. I tried the latest 1.1.6v3a and I still get the error -- Brad Pepers Linux Canada Inc.Home of Linux products in Canada! http://www.linuxcanada.com Proud supporter of Cyclades, Red [EMAIL PROTECTED] Hat, and Caldera.
Java Servlets -N- Linux?
Hello, Can Java Servlets be developed on a Linux box? We are setting up a Linux web server and want to use Java Servlets if possible. Is there a Linux version of the Java Servlet Development Kit or do I need something like JRun from livesoftware ( http://www.livesoftware.com )? Any help is appreciated Steve Curry

Re: about exec
Hi |
here is how I made this :

public void startService(String programName) {
try {
path = "/your/path/";
(Runtime.getRuntime()).exec(path+programName);
}
catch (Exception e) {
System.out.println(e);
}
}

Re: Compile Java to Native?
Yes, the tool is called TowerJ, from Tower Technology (http://www.twr.com/). TowerJ-compiled Java is faster than *any* JIT on *any* platform (as you might expect). Currently, this group has only ported TowerJ to HP's *nix and Linux (I just checked their homepage, and found out that they have ported it to Digital Unix for Alpha, as well!). Cygnus (I think) is also creating a front end to egcs (where new code is alpha/beta tested for gcc). This project is called gc1, I think. It is mentioned in the latest issue of Dr. Dobb's Journal. The benefit is that this project will capitalize on gcc's well-tested and robust optimization stages, as well as the diverse number of platforms under which gcc runs. My understanding of this project is that it is not yet finished, and may not be finished for a while. However, my sources for this understanding are dubious at best.

Re: Compile Java to Native?
Correction to my previous post -- the Cygnus Java/gcc project is called jcl. You can read about it at: http://www.cygnus.com/news/whitepapers/evaluate.html It appears that it may be closer to completion than I was originally led to believe. -dan [EMAIL PROTECTED] [EMAIL PROTECTED] Eugene Teh wrote: > Hi, > > I keep hearing people telling me that you can do this > But I have never found info about how to do this? > Is there such a utility - AFAIK Sun does not provide one? > Also what's the performance issue?
