problem in contacting the servlet

[mkarthik90]

I am using the reverseAjax technique to dynamically push the data from the servlet to a jsp page.
I am trying to contact another servlet for making some business logic, when i try to do so i am getting the error in the console as below java.lang.ClassNotFoundException: controller.querygen

But there exsists a package named controller and a querygen servlet. What could be the reason ? Is it because another servlet is already sending data dynamically to the jsp page and any exception arises?

And the following is displayed in the browser

javax.servlet.ServletException: Wrapper cannot find servlet class controller.querygen or a class it depends on
org.apache.catalina.valves.ErrorReportValve.invoke (ErrorReportValve.java:102)
org.apache.catalina.connector.CoyoteAdapter.servic e(CoyoteAdapter.java:293)

java.lang.Thread.run(Unknown Source)

What's the route through your code?
Anyway, that error does imply the server can't find that class.

Now theproject is working fine. Its because the problem with the web.xml. Identified those and solved. Since i used these lines in the web.xml javaee has been automatically added and there by caused the problem

<web-app xmlns:javaee="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="query_process">
When i removed the javaee from the code its woking fine now . I dont understand why such error occured. It gave some parser error so i changed it and its working now .
