grails activemq 应用程序不适用于 jelastic paas

Question

尝试将我的grails应用程序部署到jelastic环境并配置正确的TomEE应用程序服务器以及与activemq相关的所有插件，我在服务器上遇到以下异常:

在我的本地环境中，我将 IntelliJ 与嵌入式 tomcat 和 tomEE 服务器一起使用，并且它工作正常。我认为该问题与 activemq 没有足够的权限在磁盘上创建一些文件有关。不幸的是我无法弄清楚问题出在哪里。非常感谢任何建议。

在下面找到适用于 Jelastic(tomcat 7、java7、grails 2.2.4)环境的解决方案:

BuildConfig.groovy:

compile 'org.grails.plugins:jms:1.3'
compile 'org.apache.activemq:activemq-core:5.7.0'
compile 'org.apache.xbean:xbean-spring:4.1'

资源.groovy:

import org.apache.activemq.broker.TransportConnector
import org.apache.activemq.xbean.XBeanBrokerService
import org.springframework.jms.connection.SingleConnectionFactory

beans = {

tcpConnector(TransportConnector,uri:'tcp://localhost:61616'){}

connectors(ArrayList,[ref('tcpConnector')]){}
myBrokerService(XBeanBrokerService){bean->
    myBrokerService.useJmx = false
    myBrokerService.persistent = true
    myBrokerService.dataDirectory = 'my-activemq_data'
    myBrokerService.transportConnectors = ref('connectors')
}
amqConnectionFactory(org.apache.activemq.ActiveMQConnectionFactory) {
    brokerURL = 'vm://localhost'
}

jmsConnectionFactory(SingleConnectionFactory) { bean ->
    targetConnectionFactory = ref(amqConnectionFactory)
 }
}

嵌入式 activemq 启动时没有任何问题。
