I am trying to load some Custom Meta from a component which is published into the Tridion Broker.

This is 2009 SP1

I can see the component in the Custom_Meta table with a query like:

SELECT * FROM [Tridion_Broker].[dbo].[CUSTOM_META] WHERE ITEM_ID = 204221

However using the below code, I get a Java Runtime exception.

    string queryStringId = HttpUtility.UrlDecode(Request.QueryString["component_uri"]);

    string pageId = ((BasePage) Page).PageTcmId;
    int publicationId = int.Parse(pageId.Split(':')[1].Split('-')[0]);
    using (var cmf = new ComponentMetaFactory(publicationId))
    {
        IComponentMeta cm = cmf.GetMeta(queryStringId);
        if(cm != null)
        {
            VideoId = cm.CustomMeta.GetValue("video_url").ToString();
        }
        else
        {
            litMessage.Visible = true;
        }
    }
