请问一个带有javabean的.jsp文件如何在weblogic上发布不成功呢？

[morebest]

如何发布一个带有javabean的.jsp呢?老是有错？说：
sc.IndexBean=null.等四个错误？
sc为包的名字
IndexBean为类名
oracle为jsp页面中的id号

我已经完成在weblogic上发布一个不带javabean的,只是一但有javabean就会出错？

D:\bea\user_projects\mydomain\.\myserver\.wlnotdelete\sc_sc_myserver\jsp_servlet\__index.java:137: package sc does not exist
sc.IndexBean oracle = null; //[ /index.jsp; Line: 2]
^
D:\bea\user_projects\mydomain\.\myserver\.wlnotdelete\sc_sc_myserver\jsp_servlet\__index.java:138: package sc does not exist
oracle = (sc.IndexBean)session.getAttribute("oracle"); //[ /index.jsp; Line: 2]
^
D:\bea\user_projects\mydomain\.\myserver\.wlnotdelete\sc_sc_myserver\jsp_servlet\__index.java:141: package sc does not exist
oracle = (sc.IndexBean)session.getAttribute("oracle"); //[ /index.jsp; Line: 2]
^
D:\bea\user_projects\mydomain\.\myserver\.wlnotdelete\sc_sc_myserver\jsp_servlet\__index.java:143: package sc does not exist
oracle = new sc.IndexBean(); //[ /index.jsp; Line: 2]


为什么一但带上javabean就不行了呢？求？
