Java JMS池分配问题

我有一个JMS应用程序（使用glass fish），它可以在本地主机上完美地工作。在部署到我的服务器后，我会在第一次调用服务时不断获得堆栈下的跟踪

从堆栈跟踪线67开始

queueConnection = queueConnectionFactory.createQueueConnection();

谢谢。

好的，我发现问题了。这是一个记忆问题。我的服务器上有756MB。当我部署JMS应用程序时，我还剩下112MB。出于某种原因，glassfish无法从剩余的112MB内存中为jms池分配内存。我将vps升级到1GB，一切正常。

它真的是“jms/MyConnectionFactor”而不是“jms/MyConnectionFactory”吗？是的。这是一个打字错误，我懒得重新命名。英雄联盟

queueConnection = queueConnectionFactory.createQueueConnection();
