我是ejb的新手，我正在尝试创建一个简单的hello world应用程序，但我无法连接到服务器，无法确定问题所在。我也得到了类未找到异常，并且不知道它是否与连接错误有关。任何帮助将不胜感激。

答案 0 :(得分：0)
根据日志，您有两个问题：
1）端口9990已在使用中：
Address already in use: bind localhost/127.0.0.1:9990 - 停止所有JBoss进程以及使用端口9990重启的任何其他进程，让我们知道它是如何运行的。
2）不支持的major.minor版本52.0 at java.lang.ClassLoader.defineClass1（Native Method）[rt.jar：1.7.0_79] 在java.lang.ClassLoader.defineClass（ClassLoader.java:800）[rt.jar：1.7.0_79]
您正在JVM上运行应用程序，该JVM不支持用于编译应用程序的JDK。检查您在开发环境中使用的Java编译器版本（取决于您的IDE，版本），并确保它是1.7.0_79或更低。
或者让JBoss在与开发JDK相同的jvm版本中运行。
答案 1 :(得分：0)
日志中有两个主要错误
1 - 地址已经
Address already in use: bind localhost/127.0.0.1:9990
此错误告诉您另一个进程正在使用端口9990。通常是另一个jboss实例。你必须停止其中一个。
2 - 不支持的major.minor版本
java.lang.UnsupportedClassVersionError: com/businnesslogic/HelloWorldBean : Unsupported major.minor version 52.0
这告诉您使用一个版本的java编译源代码，然后尝试使用另一个版本运行它。
由于此错误，您的应用程序未被部署。
