春天，JMS丢失上下文 [英] Spring, jms lost context

问题描述

我正在编写使用少量工作人员的webapp.我决定使用JMS ActiveMQ在它们之间进行通信.我的问题是，当我将worker配置更改为java(当配置在xml中时，我无法运行jar)，当消息返回到webapp时，我遇到了问题:

i'm writing webapp that uses few workers. I decide to use JMS ActiveMQ to communication between them. My problem is that when i change workers configuration to java (when config was in xml i couldn't run jar) i have problem when message returns to webapp :

我不知道响应消息回来时如何接收上下文.

I don't have any idea how to receive context back when response message come back.

推荐答案

您正试图从JMS线程访问Web资源，这是不允许的.

You are attempting to access web resources from a JMS thread and that's not allowed.

有问题的代码似乎在CalculateResponseListener.getResultURL()中.

The offending code seems to be in CalculateResponseListener.getResultURL().

您需要重新架构应用程序以避免这种情况.

You need to re-architect your application to avoid this.
