Error deprecated
Hi,
I'm using a JavaBean from a JSP with Tomcat 4.0.6, Tomcat can found the three files, but Im getting an error, and I think the code is good, because is an example from a book.
I have 3 files:
- beans.html -->Root
- beans.jsp -->Root
This the first part of the file:
<jsp:useBean id="languageBean" scope="page" class="LanguageBean">
<jsp:setProperty name="languageBean" property="*"/>
</jsp:useBean>
<html>
<head>
- LanguageBean.class -->WEB-INF/classes/
This is the error I'm getting:
Apache Tomcat/4.0.6 - HTTP Status 500 - Internal Server Error

C:\Program Files\Apache Tomcat 4.0\work\Standalone\localhost\_\beans$jsp.java:108: Class org.apache.jsp.LanguageBean, this error is because you must to import the class because if you don't import the class the server try to find it in the jsp package classes and don't fint it.
