error code in JSP(please chek the code)
When I am calling the JSP(datahandler.jsp) file below from a HTML file, I
am getting the error below.Please check it and let me know as to how to solve
it.Second thing is the datahandler.jsp file uses a Bean(DataAccessBean to
store the input from the user(HTML)).It is setter and getter methods.using
its set methods I am trapping the values of name, address etc from HTML and
storing them in to bean.After that I am trying to retrieve the values using
the getter mthods and display them onto screen using JSP expressions.That
is what I want to do.Please check with the code below for all 3 programs
and also the error code and let me know the answer.
Regards
Satish

Re: error code in JSP(please chek the code)
Dear Satish,
This should be the fully qualified name of the class in the environment and
not a path to its location (although the path a class file is is used to
resolve its fully qualified name).
For example that should be:
<%@ page import="JavaEdit.DataAccessBean" %>
<jsp:useBean class="DataAccessBean" ....
This would be correct if the whole "E:\" disk is part of the CLASSPATH (refer
to my last email) environment variable or some other path used by the application
server in order to resolve the fully qualified class names used by a particular
set of applications (BEA WebLogic, for example, seems to use two different
paths for servlets and for ordinary classes).
Let me know if you need further help.
Fernando Ribeiro
