需要帮助调试 GWT - Jetty“未知领域”
我正在尝试调试 GWT 应用程序，但似乎无法使用 jetty 来做到这一点。每当我尝试在托管模式下运行它进行调试时，我都会收到“未知领域”500 错误消息（没有加载任何内容）。我是通过 eclipse 来做到这一点的。事后必须编译所有内容才能在浏览器中进行调试，非常不方便。
编译后，我将 war 部署到 JBoss 中（在服务器上使用 EJB）。但编译需要时间，当代码变成 JavaScript 后，你就无法真正调试了。如何调试java代码？我正在研究 -noserver 选项，但我想知道我是否仍然可以使用 jetty 来做到这一点。如果没有，为什么不呢？
I am trying to debug a GWT application, but it seems I can't do it with jetty. Whenever I try to run it in hosted mode for debugging I get an 'unknown realm' 500 error message (nothing loads). I am doing this via eclipse. It is very uncovenient to have to compile everything to debug in the browser afterwards.
After compilation I deploy the war into JBoss (using EJB on the server). But compilation takes time and when the code has been turned into javascript, you can't really debug. How can I debug the java code? I am looking into the -noserver option, but I wonder if I could still do it with jetty. And if not, why not.

您的问题有两点：
web.xml中有一个userRealm放入jetty-web.xml并且您现在可以在web.xml中使用-noserver来调试 GWT 代码：使用-noserver您将不会在 DevMode 中使用嵌入式 Jetty，因此只有您的客户端代码会在 DevMode 中运行。您的服务器端代码将在部署应用程序的服务器内运行，您将像调试任何其他 Java 服务器端代码一样对其进行调试（即以调试模式启动 JBoss 服务器并远程连接到它） 使用 Java 调试器）。要使用-noserver，您必须确保您的服务器提供.nocache.js和hosted.html文件，方法是先编译您的 GWT 代码并部署它，或者使用服务器的应用程序文件夹作为 DevMode 的-war（因此 DevMode 将在 Web 服务器提供文件的同一文件夹中生成文件）There are two points in your question:
<login-config>in yourweb.xml): see http://code.google.com/p/google-web-toolkit/issues/detail?id=4462#c5 (now that this bug is fixed, you only have to put theuserRealmin thejetty-web.xmland you can now use<login-config>in yourweb.xml)-noserverto debug GWT code: using-noserveryou won't be using the embedded Jetty in DevMode, so only your client-side code will run in DevMode. Your server-side code will run within the server where you deployed the app, and you'll debug it as you would debug any other Java server-side code (i.e. launch your JBoss server in debug mode and connect to it remotely with a Java debugger). To use-noserveryou have to make sure the.nocache.jsandhosted.htmlfiles are served by your server, either by first compiling your GWT code and deploying it, or by using your server's app folder as the-warof the DevMode (so DevMode will generate the files in the same folder as the web server serves files from)您能介绍一下背景吗？您是否刚刚开始这个项目，或者它正在运行，然后出现了问题？您的运行配置命令是吗？

Could you give a little background? Did you just started up this project or was it working and then something went wrong? Are are your run configs commands?
