what is cannot be resolved to a type error?
When i run jsp programs, am getting :
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 6 in the jsp file: /dbcoffee.jsp
Generated servlet error:
CoffeeQBean cannot be resolved to a type

what does cannot be resolved to a type mean?
modify web.xml file in conf dir
<init-param>
<param-name>fork</param-name>
<param-value>false</param-value>
</init-param>
into
<init-param>
<param-name>fork</param-name>
<param-value>true</param-value>
</init-param>
and restart the server
I have exact same problem. I don't understand where to turn the false value into true since my web.xml doesn't have any word says "false". I am attaching my web.xml as follow:
<?xml version="1.0" encoding="ISO-8859-1"?>

I think you are looking at the wrong web.xml file. He meant the one in your %catalina_home%/conf directory
That said, I changed my fork to true, but other possible problems:
not including classfiles in ur jsp <%@ page import="classfile" %>
not having the classfiles in the WEB-INF/classes directory of your webapp
I have been running webapps without deploying them for a while, and putting my classes in the webapps/ROOT directory. Now that I am trying to get my act together I faced this same problem, and it was all fixed by putting the relevant class files in the specific webapps web-inf directory as well as changing the fork parameter to true
hi,
previously i also have this error(cannot be resolved to a type error). But after i did the thing that u mention the new error message comes to me.
I already
1. put <%@ page import = "fooddler.FooddlerIndexer"...
2. put the FooddlerIndexer.class under mywebWEB-INF/classes/
3. modify the web.xml at conf/web.xml with <Context reloadable="true">
Below is the error msg that i get
javax.servlet.ServletException: FooddlerIndexer
