Hi , i have written a small application using Spring framework, i am getting the following error while parsing the springapp-servlet.xml,

<Apr 7, 2006 3:26:02 PM IST> <Error> <HTTP> <BEA-101216> <Servlet: "springapp" f
ailed to preload on startup in Web application: "springapp".
javax.servlet.ServletException: Error registering bean with name 'springappContr
oller' defined in ServletContext resource [/WEB-INF/springapp-servlet.xml]: Bean
 class [com.SpringappController] not found; nested exception is java.lang.ClassN
otFoundException: com.SpringappController


-------------------------------------------------------------------------------------------------------------------------------------------
springapp-servlet.xml :-

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"><!--  - Application context definition for "springapp" DispatcherServlet.  -->
<beans>
      <bean id="springappController" class="com.SpringappController" />
      <bean id="urlMapping"
            class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
            <property name="mappings">
                  <props>
                        <prop key="/hello.htm">springappController</prop>
                  </props>
            </property>
      </bean>
</beans>
-------------------------------------------------------------------------------------------------------------------------------------------

this is the controller code,

package com;
import org.springframework.web.servlet.mvc.Controller;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;

public class SpringappController implements Controller
{
      /** Logger for this class and subclasses */
      protected final Log logger = LogFactory.getLog(getClass());

      public ModelAndView handleRequest(HttpServletRequest request,
                  HttpServletResponse response) throws ServletException, IOException
      {
            logger.info("SpringappController - returning hello view");

            return new ModelAndView("hello.jsp");
      }
}


i have placed com package in the classes folder and springapp-servlet.xml in the WEB-INF folder.

I need urgent help.

looks ok, there should be a file

WEB-INF/classes/com/SpringappController.class

are all the spring and other required jars in WEB-INF/lib

yes , the path is right, i have placed spring.jar and also the logging jars in the WEB-INF/lib folder.
any other jar related to spring is needed.

yes, you can download the dependencise here:
http://sourceforge.net/project/showfiles.php?group_id=73357&package_id=73406&release_id=396613

check your logs, there may well be more details or earlier statup errors there.

not sure what the problem is, from what you've said everything is where it should be.

Hi objects,

i deployed the same war in the tomcat server, its working fine, i dont know what went wrong in weblogic.

Spring is supported in Weblogic 8.1 or not.

I need to know the problem, since the app server to be used is web logic.

Hi, i tried on my colleagues machine, i deployed the same war file on weblogic , its working fine.
I think there is some configuration problem in my system. Thanks a lot for all your contribution.
