urlrewrite and opensessioninviewfilter doesn't work together

I started my new Spring mvc project and I decided to go with SpringSource ToolSuite. When I create a project it automatically creates urlrewrite filter in my web.xml, which I'm enjoying very much. However, this brilliant urlrewrite thing doesn't seem to work with opensessioninviewfilter. Does anybody can help me?

Here is my web.xml(I tried by changing the order of filters.)

<?xml version="1.0" encoding="UTF-8"?>

    <servlet-mapping>
        <servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
        <url-pattern>/app/*</url-pattern>
    </servlet-mapping>



</web-app>

This exact thing was happening to me and the solution proposed by axtavt over here for a different filter works a treat on this one too.

Just declare your OpenSessionInViewFilter filter-mapping like this:

<filter-mapping>
    <filter-name>
        OpenPersistenceManagerInViewFilter
    </filter-name>
    <url-pattern>/app/*</url-pattern>
    <url-pattern>/api/*</url-pattern>
    <url-pattern>/admin/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

Just to keyword load incase it helps, this error manifests itself when you try to access the datastore on Google App Engine with JDO as:
