java.lang.ClassNotFoundException: org.springframework.orm.hibernate.support.OpenSessionInViewFilter

Question

i am new to spring/hibernate and was trying out my first app. I got stuck at this error, at first there was something like a 'no session factory bound to thread' error. i resolved it by declaring an OpenSessionInView filter in my web.xml given below

http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> cricket_calendar

<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/calendar-context.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>*.do</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>hibernateFilter</filter-name>
    <filter-class>org.springframework.orm.hibernate.support.OpenSessionInViewFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>hibernateFilter</filter-name>
    <url-pattern>*.do</url-pattern>
</filter-mapping>


<welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
</welcome-file-list>

Now i am getting this class not found error, but if I ctrl-shift-t and search it, its in the orm jar. i.e

no idea whats the problem, please, any help will be greatly appreciated :)

I do not know if it is a spring 3.1 change.

But you tryed to load java.lang.ClassNotFoundException: org.springframework.orm.hibernate.support.OpenSessionInViewFilter

but you have only:

• java.lang.ClassNotFoundException: org.springframework.orm.hibernate.support3.OpenSessionInViewFilter
• java.lang.ClassNotFoundExcepion: org.springframework.orm.hibernate.support4.OpenSessionInViewFilter

The difference is the 3 or 4 in the classname. -- Because you do not posted the complete stacktrace I can only make a guess.

• there is still the old package name use in a configuration file, or
• you used a lib the is written for spring 3.0, or mixed spring 3.1 and 3.0 jars
