CacheProvider null when injected

[troy.sellers]

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

The same problem occurred to me.  I could not find solution

Did you solve?

Configurition : Seam 2.2 , JBoss 5.1

javax.el.ELException: org.jboss.seam.RequiredException: @In attribute requires non-null value: authenticator.cacheProvider

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>
