jbuilder7+weblogic7+oracle8.1.5开发EJB的问题：谁能帮帮我啊！！！我分较少，不好意思。

[shjq1978]

在jb7+weblogic7+oracle8.1.5环境下开发EJB死活不成功（无论是CMP还是BMP）。EJB写好后，调用findByPrimaryKey方法，返回错误如下，看样子是找不到该记录，但该记录的确存在SYSTEM.TESTUSER。写一测试bean，能连接到数据库并能返回记录。如果将驱动程序换成ms sqlserver的odbc,则没有该现象。我是通过weblogic7的oracle连接池访问数据库的。谁有在上述环境下的开发经验，麻烦指点一下，谢谢。
