我有一個獨立的Spring命令和控制應用程序,通過Spring JMS API使用ActiveMQ廣播系統狀態。這工作正常,我已經測試了它,並有一個測試客戶端程序,可以註冊聽該主題。通過Spring問題使用ActiveMQ GWT問題
我也有一個基於Spring的GWT應用程序,我嘗試將它註冊到ActiveMQ主題之一,以便它可以接收來自C應用程序的狀態消息。在GWT項目,我有WEB-INF下的applicationContext.xml一個:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:amq="http://activemq.apache.org/schema/core"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://activemq.apache.org/schema/core
http://activemq.apache.org/schema/core/activemq-core-5.2.0.xsd">
<amq:topic id="embedded.sysModel" physicalName="org.apache.activemq.spring.embedded.sysmodel" />
</beans>
當我從Eclipse中運行的GWT應用程序我碰到下面的錯誤(或多個)。
15:16:20067錯誤[org.springframework.web.context.ContextLoader] - 上下文初始化失敗 org.springframework.beans.factory.parsing.BeanDefinitionParsingException: 配置問題:找不到春天NamespaceHandler對於 XML schema命名空間[http://activemq.apache.org/schema/core] 犯規資源:ServletContext的資源 [/WEB-INF/applicationContext.xml的]
現在,在這一點上,我不甚至在GWT應用程序中有任何代碼正在引用ActiveMQ或Spring JMS模板。我起初是這麼做的,但我支持所有事情找到第一個失敗點。它似乎是amq:主題行。如果我將該行註釋到applicationContext.xml文件中,那麼我的GWT應用程序將初始化並運行得很好。
這裏是我的GWT

確實,這是它的一部分。我這樣做,仍遇到同樣的問題,並進一步挖掘。感謝讓我朝這個方向發展。我的補充信息如下。 –
