Java 新部署后EJB未重新连接

我们有两个Java应用程序在两个不同的服务器上通过EJB相互通信

EJB在Spring中定义，EJB名称设置为web逻辑中的外部JNDI

<bean id="codingRemote" class="org.springframework.ejb.access.SimpleRemoteStatelessSessionProxyFactoryBean">
    <property name="jndiName" value="ejb/myEjb" />
    <property name="businessInterface" value="com.my.ej.binterface" />
    <property name="refreshHomeOnConnectFailure" value="true" />
</bean>

这是客户端日志还是远程服务器日志中的错误？您还设置了

Home>DomainName>安全性

，并在两个域上都选中了

跨域安全性启用

？这将同步两个域上的weblogic用户密码，这样他们就可以在没有您在上面看到的错误的情况下进行对话。错误在服务器上。即使删除了域，也要重新创建它，并在客户端运行时应用跨域设置。我找到了两种可能的解决方案，但我不完全确定哪一种是最好的，以及这样做是否有任何问题。
