JSP problem.After intalling the JSDK and Apache Tomcat I can run simple .jsp file but whenever I use the <useBean> action on the page I get the error saying that the useBean class is invalid. I did put the related .java file in the same directory. what else should I do?

I am just a beginner and thank you for your help.

what you mean the .java file?if you use as bean, should compile to .class at first. [air (6-9 11:54, Long long ago)] [ 传统版 | sForum ][登录后回复]2楼

(引用 air:what you mean the .java file?if you use as bean, should compile to .class at first. )I also put the .class in the same directory,but still displays error like below

org.apache.jasper.JasperException: /ValidateUser1.jsp(1,1) The value for the useBean class attribute com.instantjsp.LoginManager is invalid.

(引用 青锋:I also put the .class in the same directory,but still displays error like below org.apache.jasper.JasperException: /ValidateUse...)NOT the same folder!Please read the Tomcat manual first before you try to ask. In fact, it is stated clearly in the manual where you should put all your "beans," either in .class format or in .jar/.war form.

P.S.,
It is a good habbit to always refer to the product manuals if you have doubt. You need not to read through the whole manual, just search for the few key sections such as "installation instructions," "configurations," "trouble-shooting guide," etc. Those can most probably bring out of most common troubles easily.[Flying (6-9 18:33, Long long ago)] [ 传统版 | sForum ][登录后回复]5楼
