我正在尝试在网页上嵌入applet。我已将代码导出为IntelliJ中的压缩小程序。现在，当我尝试运行它时，我得到以下堆栈跟踪：

Ignored exception: java.lang.IllegalArgumentException: white space not allowed

我认为错误是由于尝试使用getImage()类中的Applet方法获取图像而导致的。这是代码：

try {
    image = new ImageIcon(main.getImage(main.getCodeBase(), imageName + ".png"));
} catch (Exception e) {
    e.printStackTrace();
}

供参考，这是我在HTML中使用的标签：

<applet archive="https://github.com/nrubin29/FreeFall-Applets/blob/master/Noah/Noah.war?raw=true" code="FreeFallMain"></applet>

如果您想亲自查看错误，请转到http://nrubin29.github.io/FreeFall-Applets/

谢谢！

4 个答案:

答案 0 :(得分：7)

如果你正在使用Java 8，那么看起来就是这个确切行为的公开错误：

https://bugs.openjdk.java.net/browse/JDK-8042622?page=com.atlassian.jira.plugin.system.issuetabpanels:changehistory-tabpanel

从本质上讲，错误是它是Java中的核心错误，你无能为力。因此，您必须等待Java 8u40（如果修复程序实际上达到了目标版本）。

答案 1 :(得分：1)

我有类似的问题（从java 1.7.0_67升级到java 1.8.0_25）打开一个页面，重定向到pdf文档，代码如下：

InputStream in = new URL(myUrl).openConnection().getInputStream();

我找到了一个可能的（希望是暂时的）解决方法，为那些不能等待下一个月（或4月？）的java 8u40的人提供：

try {
    InputStream in = new URL(myUrl).openConnection().getInputStream();
} catch (IllegalArgumentException iae) {
    in = sun.net.www.protocol.http.HttpURLConnection.openConnectionCheckRedirects(new URL(myUrl).openConnection());
}

您显然可以添加日志并检查打开的连接是否是HttpURLConnection的等价。

如果您认为我所做的事情是非常错误的（我认为我已经删除了非必要部分），我愿意接受建议。

答案 2 :(得分：1)

运行Windows 7我遇到了JRE 8u25和8u40的问题。我回滚到7u71，上传工作正常。希望这会有所帮助。

答案 3 :(得分：0)

看起来这些调用之一（或您的主要调用）导致加载URL（看起来像是一个jar文件），然后是重定向，并且有一个空间或其中一个响应HTTP标头名称中的选项卡。如果你在本地网络服务器而不是Github上托管applet jar / war会发生什么？
