GroovyConsole ActiveMQ错误：NoClassDefFoundError：无法初始化类org.apache.activemq.ActiveMQPrefetchPolicy

Question

我想在GroovyConsole中运行一个非常简单的ActiveMQ客户端脚本。我已经通过脚本>将Jar添加到ClassPath菜单中包含了activemq-all-5.5.0.jar和slf4j-api-1.5.11.jar。我在activemq jar中看到org.apache.activemq.ActiveMQPrefetchPolicy，但是我得到了下面的异常。

下面是脚本：

import org.apache.activemq.* 
import org.apache.activemq.command.* 
import javax.jms.* 
// 
// 
// 

def connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616") 
def connection =connectionFactory.createConnection() 

def session = connection.createSession(false,Session.AUTO_ACKNOWLEDGE) 
def dest = new ActiveMQQueue("fieldrepresentative.updatelatlong.queue") 
def producer = session.createProducer(dest) 
connection.start() 

def MapMessage message = session.createMapMessage() 
message.setString("employeeId", "TS12345") 
message.setString("latitude", "12345") 
message.setString("longitude", "97874") 

producer.send(message) 

session.close() 
connection.close() 

唯一的例外是： 2011年7月19日下午6时04分26秒org.codehaus.groovy.runtime.StackTraceUtils消毒

Answer 1

我想您还需要添加到类路径中： -

• lib/optional/slf4j-log4j12-1.5.11.jar
• 的lib /可选/ log4j的-1.2.14.jar

我想因为这个预SLF4J 1.6.0 '功能' 的： - http://www.slf4j.org/manual.html#libraries
