ClassNotFoundException 引用 JBoss AS 7 中的 hornetq 特定内容

我正在尝试在 JBoss AS 7 应用程序中使用 JMS。发布正常消息似乎工作正常,但是当我尝试使用 hornetq 特定功能(排除重复消息)时,会引发异常。 这是代码:

om.setStringProperty(org.hornetq.api.core.Message.HDR_DUPLICATE_DETECTION_ID.toString(), application+rs.getString("stream")+ rs.getInt("site"));

这是堆栈跟踪:

java.lang.ClassNotFoundException: org.hornetq.api.core.Message from [Module "deployment.TestRestEasy.war:main" from Service Module Loader]

javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

我相信我已经正确配置了standalone.xml 配置文件,因为标准JMS 代码可以正常工作。我需要做什么特殊的事情才能访问 HornetQ 的特定功能吗?

更新: 担心与我正在使用的 RestEasy 相关,因此转移到独立的 Servlet,但仍然遇到同样的问题。下面的代码和异常

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   try {
    Context ic = new InitialContext();

  QueueConnectionFactory qcf = (QueueConnectionFactory) ic.lookup("java:/ConnectionFactory");
  Queue q = (Queue) ic.lookup("queue/test");

  QueueConnection qc = qcf.createQueueConnection();
  QueueSession qsess = qc.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
  QueueSender qsend = qsess.createSender(q);

  ObjectMessage om = qsess.createObjectMessage();
  om.setObject((Serializable)new InboundDirectory("X", "Y", 9));
  om.setStringProperty(org.hornetq.api.core.Message.HDR_DUPLICATE_DETECTION_ID.toString(), "X");
  qsend.send(om);
  System.out.println("X");
  }
  catch (Exception e) {
     e.printStackTrace();
  }
}

这是异常:

java.lang.ClassNotFoundException: org.hornetq.api.core.Message from [Module "deployment.TestRestEasy.war:main" from Service Module Loader]
org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:191)

TestServlet.doGet(TestServlet.java:46)
javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

进一步更新: 通过使用字符串值来使其工作,但我认为这并不理想,属性键不能保证永远是该字符串。

om.setStringProperty("_HQ_DUPL_ID", "X:Y:9");

知道正确的方法吗?

更新:感谢@Vadzim 为我指明了正确的方向。对于其他遇到此特定问题的人,我更新了 Manifest.MF,如下所示:

Manifest-Version: 1.0
Class-Path: 
Dependencies: org.hornetq

注意,(因为我为此苦苦挣扎了一段时间),该文件的解析非常“脆弱”。 “Class-Path:”输入行后面的空格至关重要。

I am trying to use JMS in a JBoss AS 7 application. Publishing normal messages seems to work OK, however when I try to use hornetq specific features (to exclude duplicate messages), an exception is thrown.
This is the code:

om.setStringProperty(org.hornetq.api.core.Message.HDR_DUPLICATE_DETECTION_ID.toString(), application+rs.getString("stream")+ rs.getInt("site"));

And here is the stack trace:

java.lang.ClassNotFoundException: org.hornetq.api.core.Message from [Module "deployment.TestRestEasy.war:main" from Service Module Loader]
org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:191)

javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

I believe I have configured the standalone.xml configuration file correctly, as the standard JMS code works. Is there anything special I need to do to access HornetQ specific features?

Update:
Was worried was related to RestEasy stuff I was using, so moved into standalone Servlet, but still had same issue. Code and exception below

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
   try {
    Context ic = new InitialContext();

  QueueConnectionFactory qcf = (QueueConnectionFactory) ic.lookup("java:/ConnectionFactory");
  Queue q = (Queue) ic.lookup("queue/test");

  QueueConnection qc = qcf.createQueueConnection();
  QueueSession qsess = qc.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
  QueueSender qsend = qsess.createSender(q);

  ObjectMessage om = qsess.createObjectMessage();
  om.setObject((Serializable)new InboundDirectory("X", "Y", 9));
  om.setStringProperty(org.hornetq.api.core.Message.HDR_DUPLICATE_DETECTION_ID.toString(), "X");
  qsend.send(om);
  System.out.println("X");
  }
  catch (Exception e) {
     e.printStackTrace();
  }
}

And here is the exception:

java.lang.ClassNotFoundException: org.hornetq.api.core.Message from [Module "deployment.TestRestEasy.war:main" from Service Module Loader]
org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:191)
org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:361)
org.jboss.modules.ConcurrentClassLoader.performLoadClassChecked(ConcurrentClassLoader.java:333)
org.jboss.modules.ConcurrentClassLoader.performLoadClass(ConcurrentClassLoader.java:310)
org.jboss.modules.ConcurrentClassLoader.loadClass(ConcurrentClassLoader.java:103)
TestServlet.doPost(TestServlet.java:65)
TestServlet.doGet(TestServlet.java:46)
javax.servlet.http.HttpServlet.service(HttpServlet.java:734)
javax.servlet.http.HttpServlet.service(HttpServlet.java:847)

Further update:
Got it working by using the String value instead, but I don't think that is ideal, the property key is not guaranteed that string forever.

om.setStringProperty("_HQ_DUPL_ID", "X:Y:9");

Any idea the proper way to do it?

Update: Thanks @Vadzim for pointing me in the right direction. For anybody else struggling with this specific problem I updated the Manifest.MF as follows:

Manifest-Version: 1.0
Class-Path: 
Dependencies: org.hornetq

Note, (as I struggled with this for a while), the parsing of this file is very 'fragile'. The Space after the 'Class-Path:' entry line is essential.

我相信 hornetq-client 应该暴露给 HOrnetQ 模块。

也许您应该通过他们的论坛与 AS7 人员交谈..或者也许在 jira.jboss.org 上提出 AS7 项目的问题..但我相信您需要首先在论坛上交谈。

I believe the hornetq-client should be exposed to the HOrnetQ module.

Maybe you should talk to AS7 guys through their forum.. or maybe raise an issue on jira.jboss.org for the AS7 project.. but I believe you are required to talk on the forums first.
