本文介绍了应用程序在Mac OS X上使用Apple的Java 6而不是Oracle的Java 7？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在使用安装了Oracle的Java 7的Mac OS X测试我当前的应用程序。而是使用Oracle的Java 7，它使用的是Apple的Java 6。 java -version 的默认系统输出显示 7 。

我尝试了不同网站中提到的大部分内容，但我无法解决此问题。

JAVA_HOME 也已正确设置。

I我只使用Mac进行测试。我真的需要一些指导。

当我通过选择JRE 7运行Eclipse时，它运行正常。因此，应用程序没有任何问题。我在Mac OS X上遗漏了一些东西。

我的Java系统环境如下所示：

OS X版

10.8

/ usr / libexec / java_home -V

 匹配Java虚拟机（3）：
 1.7.0_12，x86_64：Java SE 7/Library/Java/JavaVirtualMachines/jdk1.7.0_12.jdk 
 1.6.0_37-b06-434， x86_64：Java SE 6/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

  jdk1.7.0_12.jdk 
  
```

/System/Library/Frameworks/JavaVM.framework/Commands/java -version
```
  java版1.6.0_37
  
```

我想我当前的JDK指向错误。

解决方案

问题

您的Mac OS X应用程序包是使用与Oracle Java 7软件包不兼容的应用程序捆绑软件创建的。例如，您使用的捆绑包可以是Apple提供的 Jar Bundler ，它仅适用于Apple的Java 6系统包。

Apple已放弃支持Java作为Java 7及更高版本的集成系统包。因此，您必须使用Oracle Java 7第三方软件包及其应用程序包捆绑解决方案。这允许您在Mac OS X 10.7.3及更高版本上创建和部署基于Oracle Java 7的应用程序包。

您面临的基本技术问题是Apple的本机 Objective-C 基于 JavaAppLauncher 二进制文件及其在 Info.plist 仅使用Apple的Java 6系统软件包，来自Oracle的 JavaAppLauncher Info.plist 组合仅起作用对于Oracle的Java 7软件包。

 
 
 当您使用支持Apple的Java 6系统软件包的 JavaAppLauncher 时，它将始终拿起Mac上安装的Apple Java 6 System Package。

I am testing my current application with Mac OS X which has Java 7 from Oracle installed. Instead using Java 7 from Oracle, it's using Java 6 from Apple. The default system output of java -version is showing 7. 

I tried most of the things mentioned in different sites, but I was unable to fix this issue. 

JAVA_HOME is also properly set.

I am using the Mac only for testing purposes. I really need some guidance on this.

When I run it with Eclipse by selecting JRE 7, it runs properly. Thus there is nothing wrong with the application. I am missing something on Mac OS X.

My Java system environment looks like this:


OS X version

10.8
/usr/libexec/java_home -V
Matching Java Virtual Machines (3):
1.7.0_12, x86_64: "Java SE 7" /Library/Java/JavaVirtualMachines/jdk1.7.0_12.jdk   
1.6.0_37-b06-434, x86_64: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
1.6.0_37-b06-434, i386: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

/usr/libexec/java_home

echo $JAVA_HOME 
/Library/Java/JavaVirtualMachines/jdk1.7.0_12.jdk/Contents/Home/

JAVA_ARCH is not set

ls /Library/Java/JavaVirtualMachines
jdk1.7.0_12.jdk

/System/Library/Frameworks/JavaVM.framework/Commands/java -version
java version "1.6.0_37"



I guess my current JDK is pointing to something wrong.
 解决方案 
Issue

Your Mac OS X application bundle has been created with an app bundler which is not compatible with Oracle's Java 7 package. The bundler you were using could be, for example, Jar Bundler provide by Apple which only works for Apple's Java 6 System Packages. 

Apple has given up support for Java as an integrated System Packages from Java 7 and later. As a consequence you have to go for the Oracle Java 7 Third Party package and their application package bundle solution. This allows you to create and deploy Oracle Java 7 based application bundles on Mac OS X 10.7.3 and onwards.

The underlying technical issue you are facing is Apple's native Objective-C based JavaAppLauncher binary and the format it uses in Info.plist is only working with Apple's Java 6 System Packages and the JavaAppLauncher Info.plist combination coming from Oracle is only working for Oracle's Java 7 Packages.

As you are using a JavaAppLauncher supporting Apple's Java 6 System Packages, it will always pick up the Apple Java 6 System Package installed on your Mac.   

There is a video, where Scott Kovatch, the lead engineer for the Mac OS X port of the Java platform at Oracle is talking on DEVOXX about how app bundling for Oracle Java 7 is working in great detail.

Solution

To create app bundles based for Mac OS X 10.7.3 and onwards based on 


Oracle's Java SE 7 (JRE 1.7.x)
OpenJDK Java SE 7 (JRE 1.7.x)


and above, you have to use Oracle's app bundler


lib/appbundler-1.0.jar containing the Ant Task com.oracle.appbundler.AppBundlerTask 


With Oracle's app bundler you have now the choice to run your packaged app with the default Oracle Java 7 Package installed on your Mac here:


/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/


or the Oracle Java 7 JRE you inline in your packaged application 


MyJavaMacOSXApp.app/Contents/PlugIns/


Note: There are pros and cons for both approaches, but you need the last one with your own JRE if you want to go to the Apple App Store with your bundled app.

What needs to be done


Download appbundler-1.0.jar and move it to <project>/lib/appbundler-1.0.jar
Add the following to your <project>/build.xml


<property environment="env" />

<taskdef 
    name="bundleapp" 
    classname="com.oracle.appbundler.AppBundlerTask" 
    classpath="lib/appbundler-1.0.jar" />

<target name="bundle">
    <bundleapp 
        outputdirectory="dist" 
        name="MyJavaMacOSXApp" 
        displayname="My Java Mac OS X App" 
        identifier="com.example.MyJavaMacOSXApp" 
        shortversion="1.0"
        applicationCategory="public.app-category.developer-tools"
        mainclassname="com.example.MyJavaMacOSXApp">
        <runtime dir="${env.JAVA_HOME}" />
        <classpath file="dist/MyJavaMacOSXApp.jar" />
    </bundleapp>
</target>


Note: You need to replace MyJavaMacOSXApp with your application data. You can find here some additional AppBundlerTask options, as this example shows only how how it works in its simplest form.
After you run the bundle target with ant bundle you will find MyJavaMacOSXApp.app in the <project>/dist directory.


What does the <runtime dir="${env.JAVA_HOME}" /> element?

Inlining Oracle Java 7 Package (JRE)

The Ant target above copies the Oracle Java 7 Package (JRE) from your 


JAVA_HOME 


into 


MyJavaMacOSXApp.app/Contents/PlugIns


So the application package is totally self contained and does not need an Oracle Java 7 Package (JRE) installed on the target system at all. Like you can see in the following screen shot of such a deployed MyJavaMacOSXApp.app:



Wiring default Oracle Java 7 Package (JRE)

If you want to use the default Oracle Java 7 Package (JRE) installed on the application bundle target Mac under 


/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/ 


you have to remove the 


<runtime dir="${env.JAVA_HOME}" /> 


element fromt the bundle task. Like you can see in the following screen shot of such a deployed MyJavaMacOSXApp.app:



Source of MyJavaMacOSXApp.java
package com.example;

import java.awt.*;
import javax.swing.*;

public class MyJavaMacOSXApp extends JPanel {

    public MyJavaMacOSXApp() {
        JLabel versionLabel = new JLabel("java.version=" + System.getProperty("java.version"));
        JLabel homeLabel = new JLabel("java.home=" + System.getProperty("java.home"));
        setLayout(new BorderLayout());
        add(versionLabel, BorderLayout.PAGE_START);
        add(homeLabel, BorderLayout.PAGE_END);
    }

    private static void createAndShowGUI() {
        JFrame frame = new JFrame("MyJavaMacOSXApp");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        MyJavaMacOSXApp newContentPane = new MyJavaMacOSXApp();
        newContentPane.setOpaque(true); 
        frame.setContentPane(newContentPane);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}


What if my app has multiple jar files?

Just add as many <classpath file="dist/additional.jar" /> entries as you need.

Note: The order of  elements in the bundle task isn't preserved at runtime of your bundled app. The java.class.path gets built up at runtime by the native JavaAppLauncher as it reads in the *.jars from MyJavaMacOSXApp.app/Contents/Java directory.



Just for completeness, this is how Info.plist looks like:
<?xml version="1.0" ?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
