請問有没有人知為何我在window下用NetBeans時,run個JSP就没有問題,正常run到login 到.

該jsp:
<jsp:useBean id="dbaccess" class="db.DbAccess" scope="application" />

我已經有把 DbAccess.java 放入 web\WEB-INF\classes\db裡.在window下run是没有問題.



但是我把一整個jsp放入linux server時就出現這個問題.

請問我要否在linux server都recompile一次呢!

另外,我在window個NetBean裡,它在/src裡開了一個java folder.它把我所有的javabean都放了進去.但我之後都把java folder裡的所有foder都copy到去\web\WEB-INF\classes裡.
這樣做對嗎?  THANKS
