Linux (Ubuntu) Java 插件和控制台 [英] Linux (Ubuntu) Java plugin and console

问题描述

我正在尝试在 Ubuntu 10.10 中的 Firefox 中测试 Java 小程序.不幸的是，它不能开箱即用.我有两个问题:

I'm trying to test a Java applet in Firefox in Ubuntu 10.10. Unfortunately it doesn't work out of the box. I have two issues:

1. 默认使用 IcedTea 插件，我不信任它.我安装了 sun-java6-plugin 但不知道 Firefox(和其他浏览器)现在使用哪个.我如何确定? 只需移除冰茶即可解决此问题.
2. 我没有控制台.它通常可以通过 Windows 中的托盘图标访问，但不是在这里(也许这会被 #1 自动修复 不，它不是).有这个插件，但它不再起作用了.更新:我已经通过转到 Java 控制面板并在高级选项卡中选中显示控制台"解决了这个问题，但现在控制台总是弹出，这还不是很完美.

1. By default the IcedTea plugin was used, which I don't trust. I installed sun-java6-plugin but have no idea which one is used by Firefox (and other browsers) now. How can I make sure? Fixed this by simply removing icedtea.
2. I have no console. It's usually accessible via a tray icon in Windows, but not here (maybe this will automatically be fixed by #1 though No it wasn't). There's this addon but it doesn't work anymore. Update: I've sort of fixed this by going to the Java control panel and checking "Show Console" in the advanced tab, but now the console always pops up which isn't quite perfect yet.

我正在通过 JNLP 部署小程序.如果有帮助，您可以在此处查看.我将 sun-java6-jdk 作为默认 Java.

I'm deploying the applet via JNLP. You can see it here, if it helps. I have sun-java6-jdk as the default Java.

(对不起，如果这个问题属于 SuperUser 或其他网站，但我认为 #2 特别是这是一个与编程相关的问题)

(Sorry if this question belongs on SuperUser or another site, but I figured that with #2 especially this is a programming related question)

推荐答案

With :

sudo update-alternatives --install "/usr/bin/java" "java" "/opt/java/64/jre1.6.0_20/bin/java" 1
sudo update-alternatives --set java /opt/java/64/jre1.6.0_20/bin/java

您可以设置默认的 jre(在本例中为 64 位)

You can set the default jre (in this case a 64 bits one)

与:

java -version

可以看到版本

通过about:plugins，您可以查看正在使用哪个jre Firefox

With about:plugins you can see which jre firefox is using
