我在（Maven）项目中同时拥有 GWT 2.5.1、Spring 3.2 和 Tiles。只要我用 mvn jetty:run-war 之类的东西开始项目，一切都很好。

一旦我尝试使用 mvn gwt:run 启动项目进入 DevMode。它抛出以下错误消息：

2013-10-07 14:49:31,676 [main] WARN  org.springframework.web.servlet.view.tiles3.TilesConfigurer - Could not obtain JSP 2.1 ExpressionFactory

... 还有这个：

java.lang.NoSuchMethodError: javax.servlet.jsp.JspFactory.getJspApplicationContext(Ljavax/servlet/ServletContext;)Ljavax/servlet/jsp/JspApplicationContext;

我相信这与 GWT 的集成 Servlet 容器有关。但是我不知道如何解决这个问题。有人可以给我一个提示吗？

非常感谢！

最可能的解决方案是包含el-ri.jar库

  <dependency>
     <groupId>com.sun.el</groupId>
     <artifactId>el-ri</artifactId>
     <version>1.0</version>
  </dependency>

我在这里遇到的问题是由 gwt 在开发模式下默认使用的嵌入式且有些过时的码头引起的。

我的主机页面不仅仅是一个静态 html 页面，而是一个使用表达式语言的 JSP（MVC 视图，Tiles 3）。由于我的配置需要比 gwt 附带的更新的 servlet 容器，因此我的项目不适用于嵌入式码头。

为了解决这个问题，我必须启动一个最近的 servlet 容器，比如 Jetty 7（Tomcat 也可以）来运行项目的服务器端（和 gwt）。

为了能够在开发模式下运行 gwt 并对其进行调试，有必要阻止它启动嵌入式服务器并为其提供在哪里可以找到服务器的信息。在我的情况下，我在开发模式参数下添加到 Intellij IDEA 的 gwt 运行/调试配置中，以下行

-noserver -war localBuild -port 8080 com.myproject.modul

当然，您必须用您的模块名称替换模块名称。端口 8080 是我的 Jetty 7 正在侦听客户端连接的端口。选项 -noserver 阻止 gwt 启动嵌入式服务器。

您还可以通过将以下行添加到 maven-gwt-plugin-configuration 来使用 maven 达到相同的结果：

        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>gwt-maven-plugin</artifactId>
            <version>2.5.1</version>
            ...
            <configuration>
                ..
                <noServer>true</noServer>
                <port>8080</port>
            </configuration>
        </plugin>

要运行/调试您的 gwt 模块，您现在只需通过调用 mvn clean jetty:run-war 启动您选择的服务器（也可以直接从您的 IDE 启动），然后像以前一样启动 gwt 的开发模式。

一个很好的副作用是刷新现在快得多，因为只要服务器端没有任何变化，嵌入式服务器就不会一直启动。

这帮助我想出了这个解决方案：http ://clojure-dev.blogspot.de/2011/12/debugging-gwt-client-side-code-with.html
