    CacheProvider null when injected

      Hi All,


      I am trying to include the jboss pojo cache into my Seam project and am having some trouble getting this to work.


      I inject the cache into a Conversation scoped object


      @In
      private CacheProvider<PojoCache> cacheProvider;


      which is confgured in the components.xml as


      <cache:jboss-pojo-cache-provider />


      I have placed the jbosscache-core-3.0.jar and jbosscache-pojo-3.0.jar on the classpath.


      When the component that is looking for the cacheProvider is instantiated it throws the following error


      org.jboss.seam.RequiredException: @In attribute requires non-null value: menu.cacheProvider


      Can anyone point me to some docs that explain how to set this up properly?


      JBoss 4.3 EAP
      Seam 2.1.0.SP1
      Java 1.5


      Cheers,
      Troy

            I too am having the same issue when I use EhCache. Does anyone have a solution?

              Add to your components.xml:


              <components xmlns="http://jboss.com/products/seam/components"
...
            xmlns:cache="http://jboss.com/products/seam/cache"
            xsi:schemaLocation=
                    "http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.1.xsd
               http://jboss.com/products/seam/cache http://www.jboss.com/products/seam/cache-2.1.xsd">

...
   <cache:eh-cache-provider/>
...
</components>
