Anybody help?

Got some jsp that uses some beans. When I start the JSP I get a:
org.apache.jasper.JasperException: Unable to load class com.awl.jspbook.ch04.Bean1
and a:
java.lang.ClassNotFoundException: Unable to load class com.awl.jspbook.ch04.Bean1

I assume this is because of the classpath or something?

How can I fix it?

Thanks
