Question

我正在使用64位JDK 1.7.1在IBM WebSphere 8.5上运行Java EE项目。

当我从Swing客户端（JDK 1.8 Oracle 64位）执行对EJB的远程调用时，将引发以下异常。我试图在客户端（甚至与服务器JDK）中使用不同的JDK，结果始终是相同的：

有人要面对这个问题吗？

提前谢谢

这些天，我遇到了类似的问题。看来这是防火墙的问题。由于ORB元回调失败，会发生许多CORBA.MARSHAL异常：

回调是（通常）从服务器发送回客户端的单独请求，必须先完成该请求，然后才能处理原始的传入请求。
仔细查看上面的堆栈，我们看到尝试了ORB元回调（可能是从服务器回到客户端）：

您可以使用参数来指示避免这种情况。

com.ibm.CORBA.enableClientCallbacks=true
