【问题讨论】：

  • 回答问题的提示：#1 提出实际问题！ #2 显示造成问题的代码。 #3 提供任何必要的上下文信息。 #4 关心你的问题格式和错别字。没有额外信息的两页堆栈跟踪并不是很有帮助。

【解决方案1】：

没有任何其他信息，我通常用谷歌搜索代码 org.jboss.ejb.txttimer.DatabasePersistencePolicy.listTimerHandles 并查找那里发生的情况。接收到 NPE 通常意味着所需的对象没有被初始化。 在这种情况下，它可能是一个错误https://jira.jboss.org/jira/browse/JBPORTAL-1855

【讨论】：

  • +1 准确。如果没有额外的配置，Ejb 3.0 不能在 jboss 4.2.3 上运行。哇！在 Jboss 5.0 上效果很好。
【解决方案2】：

在你的 bean 中使用这个注解：

@Depends({"jboss.jca:name=DefaultDS,service=DataSourceBinding","jboss:type=Service,name=SystemProperties"})
