Question

在Wildfly 10独立模式下，我使用以下代码段获取SessionContext对象

InitialContext context = new InitialContext();
UserTransaction userTrans = null;
userTrans = (UserTransaction) m_Context.lookup("java:jboss/UserTransaction");
userTrans.setTransactionTimeout(600000);

然后在SLSB中我使用

@Resource
protected SessionContext sessionontext;

但是在DOMAIN模式下执行相同的代码时，它无法使用SessionContext，因为它的值为null。

更新

@Stateless(mappedName="AppManager")
@Local(value = AppManager.class)
@Remote(value = AppManagerRemote.class)
@TransactionAttribute(TransactionAttributeType.REQUIRED)
@TransactionManagement(TransactionManagementType.CONTAINER)


    public class AppManagerBean extends AppManagerAdapter implements AppManagerRemote
    {
      try
      {
      }
      catch(Exp..)
      {
        sessionontext.setRollbackOnly();  ///Here sessionontext is null
      }
    }

    public class AppManagerAdapter
    {
        @Resource
        protected SessionContext sessionontext;
    //
    }

SessionContext注入应该在无状态bean本身。好动了

name = input("What is your name? ")
age = float(input("How old are you? "))
answer1 = (age + "!? That's very old, " + name + "!")
answer2 = (age + "? You're still young, " + name + ".")
if age > 60:
    print(answer1)
if age < 60:
    print(answer2)

从AppManagerAdapter到AppManagerBean，然后就可以了。

在Wildfly 10域模式下，SessionContext为null
