在Tomcat上运行GWT 2.4应用程序时出现问题 [英] Problem running a GWT 2.4 App on Tomcat

问题描述

在tomcat中运行我的gwt2.4rc1应用程序时遇到问题。当我尝试进行请求调用时，会出现问题。然后我得到底部的异常。

I have a problem running my gwt2.4rc1 application in a tomcat. The problem occurs when I try to make a requestfactory call. Then I get the exception at the bottom.

当我在开发模式下运行GWT时，一切正常。 gwt-dev。 jar在我的webapp的lib文件夹中。我正在使用maven进行依赖管理。我的配置可能有问题吗？我已经有gwt2.4 beta的错误。如果有任何其他信息需要解决这个问题，我很高兴提供他们。

When I run GWT in development mode everything works fine. The gwt-dev. jar is in the lib folder of my webapp. I am using maven for dependency management. Could there be a problem with my configuration? I already had the error with gwt2.4 beta. If there are any other information required to solve this problem I am glad to provide them.

问候，
Arne

Regards, Arne

推荐答案

解决这个问题的过程从RC到主干。与此同时，从您的依赖项中移除gwt-servlet并改为使用requestfactory-servlet.jar。

There's a fix for this on its way over from RC to trunk. In the mean time, remove gwt-servlet from your dependencies and use requestfactory-servlet.jar instead.
