Weblogic 12中出现EJB初始化错误，但10中没有

[英]EJB Initialization error in weblogic 12 but not in 10

问题描述

我正在处理有关遗留应用程序，weblogic和ejb的一些怪异的东西。 我有一些代码作为EAR部署在weblogic 10中，没有任何错误，但是现在，我正在针对12版本进行测试。 不幸的是，它无法成功部署。

我有一个名为“ Monitor”的单例类，并带有以下构造函数： 

 private Monitor(){
    if(MonitorProperties.getInstance().getEnabled()){
        try{                
            Context objContext = new InitialContext();
            monitorJmsGatewayRemote = (MonitorJmsGatewayRemote)objContext.lookup(MonitorProperties.getInstance().getJndiEjbGatewayProperty());
            active = true;
            if(tracer.isInfoEnabled()){
                tracer.info("'"+FrameworkApplicationContext.getInstance().getApplicationId()+"' Framework monitor is initialize");
            }           
        }catch(Exception excep){
            tracer.warn("'"+FrameworkApplicationContext.getInstance().getApplicationId()+"' It's not possible to initialize the framework monitor. "+ excep.getMessage());
            active = false;
        }       

        init();
    }else{
        active = false;
    }
}

因此，在运行时，可以启用或禁用监视器。

另一方面，我有MonitorJMSGateway ejb： 

@Stateless(name="FwkMonitorJmsGatewayBean")
@Remote(MonitorJmsGatewayRemote.class)  
public class MonitorJmsGateway implements MonitorJmsGatewayRemote {

private static Tracer tracer = null;

static{//Inicializamos el log4j
    PropertyConfigurator.configure(Thread.currentThread().getContextClassLoader().getResourceAsStream(MonitorJmsGatewayConstants.LOG4J_PROPERTIES_FILE));
    tracer = Tracer.getTracer(MonitorJmsGateway.class);
}

问题是我得到了一个空指针，因为log4.properties文件不存在。 很好，好的。 但是奇怪的是，这个应用程序是在weblogic 10中部署的，而不是在12中部署的。这听起来像是10中的懒惰初始化的事情（由于禁用了自定义监视，未初始化ejb，未引发异常）并且应用程序已成功部署）

日志错误跟踪如下

错误日志指向以下事实：类路径中没有log4j属性文件。 有趣的是，错误不会出现在weblogic 10中。

我想我已经找到了答案。 部署耳朵后，weblogic 10.3需要一个ejb-descriptor，而weblogic 12将使用注释。 这就是为什么weblogic 10运行“很好”的原因
