異常恢復延續：DWR的GlassFish

Question

我使用dwr3反向Ajax和spring mvc。當應用程序部署在tomcat(version 6)中時，一切正常。但在glassfish（版本3.1）中運行相同的應用程序時出現以下錯誤。任何幫助，高度讚賞。

我得到的錯誤;

Answer 1

一下添加到POM.This應該做的伎倆

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

後來的jar文件包含與灰熊版本檢測安裝，並會DWR適用於所有版本的GlassFish的Grizzly的類（ 9.1，9.1 ur1，Sailfin，OpenESB）。
