我试图让一个存储过程能够从Lotus Notes中的java代理调用。我已经能够使这些类型的代理能够正常工作，只要将数据移入和移出db2表，我也能够使用与我相同的用户名/密码从Iseries Navigator运行存储过程。用于此代理。但是，当我尝试运行代理时，它会给我一个错误。这是我的Java代码：

同样，存储过程在Iseries导航器中工作正常，并且在我们通常使用它的J2EE应用程序调用时，使用我在这里使用的相同用户名。当我为其他程序做选择或插入时，Java代理工作正常。有人有任何想法吗？
谢谢，
答案 0 :(得分：2)
您的代码难以阅读，但存储过程似乎需要10个参数，而您所获得的错误是不言自明的：无论您最终传递给iSeries，它都不是对该过程的有效调用。换句话说，问题不在于Domino的Java实现本身，而在于您正在进行的调用（就像您一样，我可以确认AS400存储过程在Java中运行得很好）。
像这样的例子中的主要罪魁祸首：
