从Java程序打开浏览器窗口 [英] Open Browser window from Java program

问题描述

问

我用Java编写的应用程序。它的目的是在Linux机器上运行的独立。我想产生一个新的火狐的窗口。然而，的火狐的永远打开。它始终为1的外壳退出code，我可以运行同样的code用的的gnome-terminal 的，它打开罚款。

背景

所以，这里是它的初始化过程：

1. 启动XXo​​rg的：1 -br -terminate -dpms -quiet VT7


2. 启动窗口管理器的metacity --display =：1 --replace


3. 配置资源xrdb -merge的/ etc / X11 / Xresources中


4. 从成为控制终端的后台进程和断开

一旦程序建立一个运行时，有一个按钮，用户可以单击应该产生一个Firefox窗口。这里是我的code这样做。记住x是显示运行：1。

code

 
公共布尔openBrowser（）
{
  尝试{
    流程oProc =调用Runtime.getRuntime（）EXEC（在/ usr /斌/火狐--display =：1）。
    INT bExit = oProc.waitFor（）; //这始终是1出于某种原因    返回true;  }赶上（例外五）{
    oLogger.log（Level.WARNING，打开浏览器，电子）;
    返回false;
  }
}
 

解决方案

在看过各种答案和各种评论（从提问者），这里就是我会做

1）试试这个方法的java
http://java.sun.com/j2se /1.5.0/docs/api/java/lang/ProcessBuilder.html

 的ProcessBuilder PB =新的ProcessBuilder（myCommand，myArg1，myArg2）;
地图＆LT;字符串，字符串＆GT; ENV = pb.environment（）;
env.put（VAR1，myvalue的）;
env.remove（OTHERVAR）;
env.put（VAR2，env.get（VAR1）+后缀）;
pb.directory（MYDIR）;
进程p = pb.start（）;

2）尝试做这个（启动从C火狐）/ C ++ /拼音/ Python，看看是否正在取得成功。

3）如果一切都失败了，我会推出一个shell程序和shell程序将启动Firefox !!

Question

I have an application written in Java. It is designed to run on a Linux box standalone. I am trying to spawn a new firefox window. However, firefox never opens. It always has a shell exit code of 1. I can run this same code with gnome-terminal and it opens fine.

Background

So, here is its initialization process:

1. Start X "Xorg :1 -br -terminate -dpms -quiet vt7"
2. Start Window Manager "metacity --display=:1 --replace"
3. Configure resources "xrdb -merge /etc/X11/Xresources"
4. Become a daemon and disconnect from controlling terminal

Once the program is up an running, there is a button the user can click that should spawn a firefox window. Here is my code to do that. Remember X is running on display :1.

Code

public boolean openBrowser()
{
  try {
    Process oProc = Runtime.getRuntime().exec( "/usr/bin/firefox --display=:1" );
    int bExit = oProc.waitFor();  // This is always 1 for some reason

    return true;

  } catch ( Exception e ) {
    oLogger.log( Level.WARNING, "Open Browser", e );
    return false;
  }
}

解决方案

after having read the various answers and various comments(from questioner), here's what I would do

1) try this java approach http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ProcessBuilder.html

ProcessBuilder pb = new ProcessBuilder("myCommand", "myArg1", "myArg2");
Map<String, String> env = pb.environment();
env.put("VAR1", "myValue");
env.remove("OTHERVAR");
env.put("VAR2", env.get("VAR1") + "suffix");
pb.directory("myDir");
Process p = pb.start();

2) try doing this(launching firefox) from C/C++/ruby/python and see if that is succeeding.

3) if all else fails, I would launch a shell program and that shell program would launch firefox!!
