JSP unable to find the class file

Hi,

I am trying a simple jsp which is in the HFSJ.

My JSP file is BasicCounter.jsp

<html>
<body>
The page count is:
<%
out.println(Counter.getCount());
%>
</body>
</html>

My Counter.java file is
public class Counter
{
private static int count = 0;
public static synchronized int getCount()
{
count++;
return count;
}
}

The directory structure is like this.

webapps>exam>BasicCounter.jsp

webapps>exam>web-inf>classes>Counter.class

When I try to access the BasicCounter.jsp, I am getting the following exceptions.

exception

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 4 in the jsp file: /BasicCounter.jsp
Generated servlet error:

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:264)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

root cause

note The full stack trace of the root cause is available in the Apache Tomcat/5.5.15 logs.

Any feedback is higly appreciated.

Thanks.

Did you import the class?

Do I have to? I didnt place the class in any package. The class Counter.class is in directory classes.

You haven't imported your java class in jsp. Please check how to import class in jsp. Hints : Add one statement.

You cannot import a package-less class. Put the class in a package and then import it.

Thanks. I got it.From this I understand that every class we develop should be in a package while using JSPs. Is that true.

Yes, only old version servlet container such as tomcat 3, maybe old version JVM, allows importing java class without package.

why is it not allowed to import classes without package in the latter versions of web servers?

JDK 1.4 and on disallows the importing of package-less classes.
