Question

我正在使用dwr3与spring mvc进行反向ajax。在tomcat(version 6)中部署应用程序时，一切正常。但是我在glassfish（版本3.1）中运行相同的应用程序时遇到以下错误。任何帮助都非常感谢。

我得到的错误;

将此添加到POM中。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文件包含安装了Grizzly版本的Grizzly类，并且将使DWR适用于所有GlassFish版本（9.1,9.1 ur1，Sailfin，OpenESB）。

异常恢复继续：dwr glassfish
