应用程序从weblogic 10.2.0迁移到jboss 6.1.0

jboss6.x java

sharique Khan · 技术社区 · 10 年前

我是Jboss服务器的新手。我正在将J2ee应用程序从Weblogic 10.2迁移到JBoss EAP 6.1.0。迁移时,我收到以下错误消息。如果有人知道解决方案,请提供帮助。

应用程序成功地部署在服务器上,但当我尝试通过localhost访问应用程序时,它会引发NullPointerException。

错误消息:

请帮我解决这个问题?

代码:

try
        {

            if(sqlHome == null)
            {
            /*  Properties jndiProps = new Properties(); 
                jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory"); 
                jndiProps.put(Context.PROVIDER_URL,"jnp://localhost:9990"); 
                jndiProps.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
        */      // create a context passing these properties 

                Context ctx = new InitialContext(); 
                System.out.println("check1...");
                //Object obj = ctx.lookup("SQLHelperSFOHome");

                //java:app/SQLHelperSFO             
                System.out.println("check2...");

                //sqlHome=(SQLHelperSFOHome)PortableRemoteObject.narrow(obj,SQLHelperSFOHome.class);

                //System.out.println(PortableRemoteObject.narrow(ctx.lookup("SQLHelperSFOHome"),SQLHelperSFOHome.class).toString()+"2");
                sqlHome = (SQLHelperSFOHome)PortableRemoteObject.narrow(ctx.lookup("SQLHelperSFOHome"),SQLHelperSFOHome.class);
            }
            sqlsfo = sqlHome.create();
            sqlsfo.initialize(DATASOURCE_JNDINAME);

        }
        catch(Exception e)
        {
            e.printStackTrace();
            throw new DataAccessException("UserProfileDAO","populate",e.getMessage());
        }

我尝试用以下方式更改初始上下文:

Properties jndiProps = new Properties(); 
                    jndiProps.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory"); 
                    jndiProps.put(Context.PROVIDER_URL,"jnp://localhost:9990"); 
                    jndiProps.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");

Context ctx = new InitialContext(jndiProps);

此外,此方法中使用的sysout语句不会显示在控制台上。

而不是使用

ctx.lookup("EJBclassName");

我们使用了:

ctx.lookup("java:global/EARname/EJBprojectName/EJBclassName!AbsoluteNameOfEJBClass");

它奏效了。
