高分请教<>一书中实例的调试问题??

[styq2000]

我在调试<<J2EE应用开发(weblogic+JBuilder)>>书中实例的时候出现如下问题:
例子是书中后面的一个小系统--开发网上购书系统.构造完实体bean和session bean 以后,打包,发布都没有问题,用EJB Client Test测试也没有大问题(这里就是有一点,运行测试程序的时候提示了一个facadebean找不到的信息,但再次运行的时候没有发现问题,我想应该不是大问题吧??)

不过在调试整个系统的时候,用webapplication调用facade的时候,数据就是从库里取不出来,但是提示信息表示booklist中不为空.不知道问题出在哪里??

书中的环境是weblogic 7.1+jbuilder7
我用的环境是weblogic 8+jbuilderX.
我调了很长时间了,还是搞不定呀,希望哪位高手指点一下,不甚感激呀!!!

可能是参数传递的问题，你把传递的参数打印一下，看看是不是合理！

EJB-QL 怎么写的？

[styq2000]

在程序中,只用到了两个简单的查询,一个是查询表中的所有记录,放到一个Collection中,并显示结果,一个是根据主码查询,得出整条记录也放在Collection.所以 EJB-QL就用到了一个语句Select book from BookItem as book; 其中BookItem 是实体bean的jndi,另一个直接利用了返回主键的那个函数调用,就没有写.他们就放在实体bean的函数里,然后用sessionbean中定义函数来调用实体bean中的函数来得到数据库中的数据.
