Java 无法完成没有日志的异常

尝试运行我的GWT应用程序时，我发现

EntryPoint initialization exception

Exception while loading module ch.swisstph.mortqual.mqui.client.MqInput. See Development Mode for details.

在命令行上。我找不到日志（我尝试通过.properties文件配置log4j，该文件删除了它的警告，但仍然没有给我任何日志）

那么我该如何解决这个问题呢

最有可能的两个原因是重命名我的启动页面并将一些代码推出库。

尝试在命令行参数中放入-logLevel SPAM，这将打印详细的日志，也可以在入口点代码中放入显式的GWT.log（“message”），这将告诉您它的进展情况（正常日志记录不能直接与gwt一起工作）

这描述了如何调试GWT。一般来说，我的建议是如何在eclipse中使用GWT插件直接调试GWT，eclipse中的GWT支持令人惊讶。

在控制台中？？任何stackTrace？我从未在IntelliJ IDEA中启动过GWT DevMode会话，但它不会打开一个新窗口吗？（DevMode包括日志）谢谢，我错过了GWT调试（对于其他人来说，要么查看IDEA的“模块”选项卡，要么将启动命令复制到终端上并在IDE之外运行。）不遵循Eclise的建议，IDEA在IMHO中更有用。
