我正在使用 JBoss 4.2.3.GA 并部署一个使用 Hibernate 4.1.5.SP1 的 JAR 应用程序。在我的 JAR 中，我有一个 Quartz 作业，配置如下......

@MessageDriven(activationConfig = {@ActivationConfigProperty(propertyName = "cronTrigger", propertyValue = "0 40 12 * * ?")})
@ResourceAdapter("quartz-ra.rar")
@Depends({
"jboss.ejb:service=EJBTimerService"})
public class UpdateOrgsJob implements Job {

我认为 JBoss 在一个单独的类加载器中加载 Quartz，而不是在我的 JAR 类被引用的地方，因为，即使它在我的 JAR 文件中，我也会收到错误“java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException”。如何让我的 JAR 类对 Quartz 可见？

下面是完整的堆栈跟踪...

您可以将 ehcache jar 文件放在 ${jboss.server}/lib 中，或者您也可以尝试Jboss wiki中提到的 2 种方法

1.  Delay  Quartz service startup
2.  set <attribute name="UseJBossWebLoader">true</attribute>
