我正在dwr3使用spring mvc. 当应用程序部署在tomcat(version 6). 但是在 glassfish（3.1 版）中运行相同的应用程序时出现以下错误。非常感谢任何帮助。

我得到的错误；

将此添加到 POM。这应该可以解决问题

<dependency>
  <groupId>com.sun.grizzly</groupId>
  <artifactId>grizzly-continuation</artifactId>
 <version>1.9.0-RC1</version>
</dependency>

后面的 jar 文件包含使用 Grizzly 版本检测的 Grizzly 类，并将使 DWR 适用于所有 GlassFish 版本（9.1、9.1 ur1、Sailfin、OpenESB）。
