前两天按照《Getting Started With JBoss》的教程，在JBoss-4.0.0下部署J2EE 1.4 Tutorial中的Duke银行的example，结果前面编译打包都很正常，惟独到了deploy一步出问题。报错如下：

在JBoss论坛上也看到了相关的问题，有人解答要使用“J2EE 1.4 Tutorial Update 2 (for Sun Java System Application Server Platform Edition 8 Update 1) June 22, 2004”，而不是Update 4，说是版本问题。接着我下载了Update 2，试了一下，结果还是报错。不知道什么原因。
后来发现JBoss已经有4.0.1了，于是下载安装，再配合J2EE 1.4 Tutorial Update 2，按照原先步骤又做了一遍，终于部署成功。汗啊~~~~Update 4版本的example还没有试过，估计应该没有问题。
感觉J2EE好复杂啊，照个例子做还要这么多问题，版本改了一点点就会出错。不知道其号称的portable到底指什么？
