the imageservlet class quite located in myproject/src/test folder in eclipse workspace, myproject name of eclipse project, , test package.

web.xml located in myproject/web/web-inf/web.xml , myproject.xml located @ myproject/myproject.xml

the contents of web.xml are: 

<?xml version="1.0"?> <web-app  xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4">      <servlet>         <servlet-name>imageservlet</servlet-name>         <servlet-class>test.imageservlet</servlet-class>     </servlet>     <servlet-mapping>         <servlet-name>imageservlet</servlet-name>         <url-pattern>/image</url-pattern>     </servlet-mapping> </web-app>

and contents of myproject.xml are:

can show me how fix code not throw classnotfoundexception?

sometimes on creating of filters or servlets, class file not generated in build folder in eclipse.clean application , build once, .class file generated in above said path. removes class not found error in cases.
