搞不定了，大家帮忙：CachedRowSetImpl

[好风软件工作日]

请问大家我要从一个存储过程中生成CachedRowSetImpl对象行不行啊？
CachedRowSetImpl crset=null;

crset=new CachedRowSetImpl();

crset.setDataSourceName("jdbc/Forum");
crset.setUsername("haofeng");
crset.setPassword("123");
crset.setCommand("{call loginProc(?,?)}");
crset.setString(1, "haofeng");
crset.setString(2, "123");
crset.execute();
return crset;
我的数据源：tomcat下
