TIBCO Enterprise Message Service 是一个消息服务器产品

完全支持JMS的通讯协议，在运行速度和消息吞吐量上表现非常出色，

对于Windows、Linux、Mac、AIX平台都提供支持

代码如下

#encoding=utf-8
import jpype


jvmpath=r"C:\Program Files\Java\jre1.8.0_161\bin\server\jvm.dll"

class EmsHelper(object):
  def __init__(self, server= "tcp://localhost:7222",user="admin",pwd=""):
    gemsjar = r"E:\EDriver\software\JAVA\jar\Gems.jar;D:\tibco\bw5\ems\8.2\lib\tibjms.jar;D:\tibco\bw5\ems\8.2\lib\tibcrypt.jar;D:\tibco\bw5\ems\8.2\lib\slf4j-api-1.4.2.jar;D:\tibco\bw5\ems\8.2\lib\slf4j-simple-1.4.2.jar;D:\tibco\bw5\ems\8.2\lib\tibjmsadmin.jar;D:\tibco\bw5\ems\8.2\lib\jms-2.0.jar;D:\tibco\bw5\ems\8.2\lib\jndi.jar" 
    #gemsjar = r"D:\tibco\bw5\ems\8.2\lib\jms-2.0.jar;E:\EDriver\software\JAVA\jar\tibjms.jar"
    jvmArg = "-Djava.class.path=.;%s" % gemsjar
    jpype.startJVM(jvmpath,jvmArg)
    self.TibjmsConnection = jpype.JClass('com.tibco.tibjms.TibjmsConnection')
    self.TibjmsConnectionFactory = jpype.JClass('com.tibco.tibjms.TibjmsConnectionFactory')
    
  def SendQueueMsg(self,qname="testq",msgstr=str({'id':1,'name':"tname"})):
    connfac = self.TibjmsConnectionFactory(server)
    conn=connfac.createConnection(user,pwd)
    session=conn.createSession(0,1)
    dest=session.createQueue(qname)
    msgProducer = session.createProducer(None)
    msg = session.createTextMessage()
    msg.setText(msgstr)
    msgProducer.send(dest, msg)
    conn.close()  

  def ShowQueueMsg(self,qname="testq",maxlen=5):
    connfac = self.TibjmsConnectionFactory(server)
    conn=connfac.createConnection(user,pwd)
    session=conn.createSession()
    queue = session.createQueue(qname)
    browser = session.createBrowser(queue)
    msgs = browser.getEnumeration()
    num = 0
    while(msgs.hasMoreElements()):
      num+=1
      message =msgs.nextElement()
      print message.getText()
      if(num>=maxlen):
        break
    browser.close()
    conn.close()  
    
  def HandleOneQueueMsg(self,qname="testq"):
    connfac = self.TibjmsConnectionFactory(server)
    conn=connfac.createConnection(user,pwd)
    session=conn.createSession()
    queue = session.createQueue(qname)
    dest=session.createQueue(qname)
    msgConsumer = session.createConsumer(dest)
    conn.start()
    msg = msgConsumer.receive()
    msg.acknowledge()
    self.HandleMsg(msg.getText())
    conn.close()
    
  def HandleMsg(self,msgstr):
    print "message is : ",msgstr
    
if __name__ == '__main__':
  server,user,pwd,qname,msgstr="tcp://localhost:7222","admin","","testq",str({'id':1,'name':"tname"})
  eh=EmsHelper(server,user,pwd)
  eh.HandleQueueMsg()
