Re: [Stripes-users] Stripes and Spring - Exception if doing INIT in Constructor

[Nikolaos Giannopoulos]

Ben,

Oooops!  Corrected - however the updated web.xml still results in the 
same exception at:

...
Caused by: java.lang.NullPointerException
   at 
org.stripesstuff.stripersist.Stripersist.getEntityManagerFactory(Stripersist.java:401)
   at 
org.stripesstuff.stripersist.Stripersist.getEntityManager(Stripersist.java:495)
...

with web.xml as follows:

   <listener>
       
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class><!-- 
Automatically loads:  /WEB-INF/applicationContext.xml -->
   </listener>

   <filter>
       <filter-name>StripesFilter</filter-name>
       
<filter-class>net.sourceforge.stripes.controller.StripesFilter</filter-class>
       ...
       <init-param>
           <param-name>Interceptor.Classes</param-name>
           <param-value>
               org.stripesstuff.stripersist.Stripersist,
               net.sourceforge.stripes.integration.spring.SpringInterceptor
           </param-value>
        </init-param>
       <init-param>
           <param-name>Extension.Packages</param-name>
           <param-value>
               org.lightagents.ui.stripes.extensions,
               org.lightagents.ui.stripes.reload.extensions,
           </param-value>
       </init-param>

    Ben,

    Thanks for the reply.  I tweaked the web.xml as you suggested as
    follows:

       <listener>

    
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class><!--
    Automatically loads:  /WEB-INF/applicationContext.xml -->
       </listener>

       <filter>
           <filter-name>StripesFilter</filter-name>

    
<filter-class>net.sourceforge.stripes.controller.StripesFilter</filter-class>
           ...
           <init-param>
               <param-name>Interceptor.Classes</param-name>
               <param-value>
                   org.stripesstuff.stripersist,
                 
     net.sourceforge.stripes.integration.spring.SpringInterceptor
               </param-value>
            </init-param>
           <init-param>
               <param-name>Extension.Packages</param-name>
               <param-value>
                   org.lightagents.ui.stripes.extensions,
                   org.lightagents.ui.stripes.reload.extensions
               </param-value>
           </init-param>

    However I am still getting the same exception (see below this time
    though with debug logging enabled and more than just the exception).

    Could it be that the Interceptor.Classes list only guarantees the
    order
    of "execution" but not "initialization".

    Any other ideas????
