i having error in servlet-context.xml. saying can find below classes there exist in projecct folder.

<beans:bean id="persondao" class="com.springhibernatemvc.dao.persondaoimpl">         <beans:property name="sessionfactory" ref="hibernate4annotatedsessionfactory" />     </beans:bean>     <beans:bean id="personservice" class="com.springbibernate.services.personserviceimpl">         <beans:property name="persondao" ref="persondao"></beans:property>     </beans:bean>

it saying class not found 

- class 'com.springbibernate.services.personserviceimpl'

my servlet-context file defined in web.xml file

<servlet>         <servlet-name>appservlet</servlet-name>         <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>         <init-param>             <param-name>contextconfiglocation</param-name>             <param-value>/web-inf/spring/appservlet/servlet-context.xml</param-value>         </init-param>         <load-on-startup>1</load-on-startup>     </servlet>

i have adding servlet-context.xml root folder of web app still error exists.

complete stacktrace

org.springframework.beans.factory.beancreationexception: error creating bean name 'org.springframework.web.servlet.mvc.method.annotation.requestmappinghandlermapping#0': invocation of init method failed; nested exception org.springframework.beans.factory.cannotloadbeanclassexception: cannot find class [com.springhibernatemvc.dao.persondaoimpl] bean name 'persondao' defined in servletcontext resource [/web-inf/spring/appservlet/servlet-context.xml]; nested exception java.lang.classnotfoundexception: com.springhibernatemvc.dao.persondaoimpl related cause: org.springframework.beans.factory.cannotloadbeanclassexception: cannot find class [com.springhibernatemvc.dao.persondaoimpl] bean name 'persondao' defined in servletcontext resource [/web-inf/spring/appservlet/servlet-context.xml]; nested exception java.lang.classnotfoundexception: com.springhibernatemvc.dao.persondaoimpl

what wrong?

from java docs

thrown when application tries load in class through string name using:

  • the forname method in class class.
  • the findsystemclass method in class classloader .
  • the loadclass method in class classloader.

but no definition class specified name found.

the problem here not servlet-context.xml beans defined in there. make sure full cannonical class names correct , respective class files present under web-inf or library under .

from first high level seems defining bean class 'com.springbibernate.services.personserviceimpl'

where correct name appears 'com.springhibernate.services.personserviceimpl'

so xml content should :

<beans:bean id="persondao" class="com.springhibernatemvc.dao.persondaoimpl">         <beans:property name="sessionfactory" ref="hibernate4annotatedsessionfactory" />     </beans:bean>     <beans:bean id="personservice" class="com.springhibernate.services.personserviceimpl">         <beans:property name="persondao" ref="persondao"></beans:property>     </beans:bean>
