weblogic 12中的java EJB初始化错误，而不是weblogic 10中的错误
我正在处理一些关于遗留应用程序weblogic和ejb的奇怪东西。我有一些代码作为EAR部署在weblogic 10中，没有任何错误，但现在，我正在针对12版本进行测试。不幸的是，它没有成功部署
我有一个名为“Monitor”的单例类，具有以下构造函数：
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，监视器可能被启用或禁用
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。属性文件不存在。好的。但奇怪的是，这个应用程序部署在WebLogic10中，而不是12中。这听起来像是10中的延迟初始化（由于禁用了自定义监视，ejb没有初始化，没有引发异常，并且成功部署了应用程序）
日志错误跟踪如下所示

错误日志指出类路径中没有log4j属性文件。有趣的是weblogic 10中没有出现错误
# 1 楼答案
我想我找到了答案。部署ear时，weblogic 10.3需要一个ejb描述符，weblogic 12使用注释。这就是weblogic 10运行“良好”的原因
