weblogic 12 中的 EJB 初始化错误，但 10 中没有
EJB Initialization error in weblogic 12 but not in 10
我正在处理一些关于遗留应用程序、weblogic 和 ejb 的奇怪问题。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 版本对其进行测试。不幸的是，它没有成功部署。
我有一个名为 "Monitor" 的单例 class，其构造函数为：
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，监视器可能会启用或禁用。
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.properties 文件不存在。没关系，好的。但奇怪的是，这个应用程序部署在 weblogic 10 中，而不是在 12 中。这听起来像是 10 中的延迟初始化东西（由于自定义监控被禁用，ejb 没有初始化，没有引发异常并且应用程序已成功部署）
