本文介绍了如何配置Chrome的Java插件,以便它使用机器中现有的JDK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


  1. 使用Oracle安装程序安装最新的1.7 JDK。

    在我的机器(Windows 7)中安装JDK时,我执行以下操作。 (只是JDK,没有 JRE



  2. 卸载Java

  3. 设置%JAVA_HOME%,添加%JAVA_HOME%,然后将该文件夹复制到我真正想要的位置,删除示例等。 \bin到%Path%然后我在所有机器中同步该文件夹,这样我就可以更新它(使用无限制的加密技术, jssecacerts java.policy ,认可的库等)。



    但有一点需要注意,Chrome需要要使用加载使用Java的页面,它认为Java未安装并且想要安装它。我不想安装它,因为它会混淆我的'手动安装'的JDK。



    那么有没有办法配置Chrome,因此它使用JDK我的磁盘?
    我有JDK 32位和JDK 64位,所以这不是问题(我想我需要使用Chrome的32位版本)。



    我在Chrome项目中发现了一个问题, 如何在不重新安装Java的情况下使Chrome浏览器插件引用现有的JDK? ,但目前为止还没有回复...



    更新:对于Ubuntu,请参阅Kalyan的回答

    更新:我仍然继续成功使用这种方法,上次在1.7版本上使用win7



    更新为1.7.45:现在Windows注册表中的路径是[HKEY_LOCAL_MACHINE \ SOFTWARE \MozillaPlugins]

    解决方案

    显然,当Chrome寻找Java环境时,Chrome会在Windows注册表中寻找一个关键字。由于该插件安装了JRE,因此该键被设置为JRE路径,因此如果您希望Chrome能够与JDK一起使用,则需要对其进行编辑。

    1. 运行插件安装程序。

    2. 开始 - >运行( Winkey + R ),然后输入 regedit 编辑注册表。

    3. 找到 HKEY_LOCAL_MACHINE \SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin
    4. >
    5. 将其导出为注册文件以说出您的桌面(右键单击并选择导出)。 卸载JRE控制面板 - >添加或删除程序)。这应该删除上面的密钥,解释首先需要导出它。

    6. 使用文本编辑器(例如Notepad ++)打开导出到桌面的reg文件。

    8. 编辑Path,以便它与JDK安装中相应的dll匹配:

        REGEDIT 4 

      [HKEY_LOCAL_MACHINE \SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin]
      Description=Oracle®Next Generation Java™Plug-In
      GeckoVersion=1.9

      Path=C:\程序文件(x86)\Java\jdk1.6.0_29\jre\bin\ new_plugin\\\
      pjp2.dll

      ProductName=Oracle®Java™插件
      供应商=Oracle Corp.
      Version=160_29


    9. 保存文件。




    10. $ b

      REGEDIT 4 文件顶部的前缀可能仅适用于Windows 7 64位。


      When installing JDK in my machines (Windows 7), I do the following.

      1. install latest 1.7 JDK with the Oracle installer (just the JDK, no JRE)
      2. copy the install folder, to the place I really want, remove samples, etc.
      3. uninstall Java
      4. set %JAVA_HOME%, add %JAVA_HOME%\bin to %Path%

      Then I synchronise that folder in all my machines so I keep it updated (with unlimited cryptography stuff, jssecacerts, java.policy, endorsed libraries, etc).

      BUT this has one big caveat, when Chrome needs to use load a page that uses Java, it thinks Java is not installed and wants to install it. I don't want to install it as it would mess with my 'hand-installed' JDK.

      So is there a way to configure Chrome so it uses the JDK in my disk? I have both JDK 32-bit and JDK 64-bit, so that is not a problem (I guess I would need to use the 32-bit one with Chrome).

      I found a question in the Chrome project, How do I have the Chrome Java plugin reference an existing JDK without reinstalling Java?, but no replies so far...

      UPDATE: for Ubuntu, see Kalyan's answer

      UPDATE: I still continue to use this approach successfully, last time with 1.7.0_21 on win7

      UPDATE for 1.7.45: the path in the windows registry now is [HKEY_LOCAL_MACHINE\SOFTWARE\MozillaPlugins]

      解决方案

      Apparently, Chrome addresses a key in Windows registry when it looks for a Java Environment. Since the plugin installs the JRE, this key is set to a JRE path and therefore needs to be edited if you want Chrome to work with the JDK.

      1. Run the plugin installer anyways.
      2. Start -> Run (Winkey+R) and then type in regedit to edit the registry.
      3. Find HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin.
      4. Export it as a reg file to say, your desktop (right-click and select Export).
      5. Uninstall the JRE (Control Panel -> Add or Remove Programs). This should delete the key above, explaining the need to export it in the first place.
      6. Open the reg file exported to your desktop with a text editor (such as Notepad++).
      7. Edit "Path" so that it matches the corresponding dll inside your JDK installation:

        REGEDIT 4
        
        [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@java.com/JavaPlugin]
        "Description"="Oracle® Next Generation Java™ Plug-In"
        "GeckoVersion"="1.9"
        
        "Path"="C:\Program Files (x86)\Java\jdk1.6.0_29\jre\bin\new_plugin\npjp2.dll"
        
        "ProductName"="Oracle® Java™ Plug-In"
        "Vendor"="Oracle Corp."
        "Version"="160_29"
        

      8. Save file.

      9. Double click modified reg file to add keys to your registry.

      The REGEDIT 4 prefix at the top of the file might only be required for Windows 7 64-bit.
