我的 (Maven) 项目中有 GWT 2.5.1、Spring 3.2 和 Tiles。只要我使用 mvn jetty:run-war 之类的东西启动项目，一切都会正常工作。
当我尝试使用 mvn gwt:run 进入 DevMode 启动项目时。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:

我相信这与GWT集成的Servlet容器有关。但是我不知道如何解决这个问题。有人可以给我提示吗？
非常感谢!
最佳答案
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>
关于java - 无法获取 JSP 2.1 ExpressionFactory :jsp EL，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/19225693/
