The problem, which I could see, during runtime the servlet trying to access some class but it is not available.

First check what external classes/JARS this servlet is dependent on.

You need to put these classes under
%CONTEXT-ROOT%/WEB-INF/Classes(Servlet directory) or

If the dependent classes availble to you as JAR then put it inside %CONTEXT-ROOT%/WEB-INF/lib/xyz.jar

Remember the container needs to access these classes during runtime!



Hope this helps!!!

whenever u get this error you should first confirm ur classpath.if you are getting again and again try to set classpath once again with following syntax on command prompt

set classpath=%classpath%;your foldername;.;
for example:-
c:javaprogram>setpath=%classpath%;c:javaprogram;.;
