Exception loading CustomMeta from Tridion Broker Service (2009 SP1)

问题

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 on the line where I do GetMeta. I have noticed that if my queryStringId is a proper TCM ID then it will throw the excpetion but if I just put the item Id it will return null.

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;
    }
}

Stack trace:

Update I have looked in the Broker log with the log enabled on "info" level and am seeing nothing after "Tridion Broker is enabled". Is this a configuration or DLL problem? It looks like the CD is not calling the service at all?

Update 2 I have tried a lot of things and still no help. It's like the code is not able to communicate with the JVM, however I can see the JVM being started in the event log.

回答1:

Are you using Java 1.6? I think you may be using the JDBC driver is for Java 1.5, if so download the latest driver from here

Also double check all your bindings in broker config!

回答2:

Typically when I had this kind of error, it was because one of the following:

the Java run-time was not installed or available to the web-app (from previous comments I see this is not the case for you). Have you checked the event viewer (either Tridion or Tridion Content Manager) for errors? Something like 'Unable to locate JVM'...
missing JAR - a Tridion or 3rd party JAR is missing from your classpath (which could be under your webroot/bin/lib);
configuration error (Tridion config is wrong, somewhere in webroot/bin/config);
missing license file (check the webroot/bin/config/cd_licenses.xml or maybe your config files point to another cd_licenses.xml, which might not be available or accessible to the web app app-pool user). A missing license is maybe the trickiest. All you see in the log is a subtle mention stating that due to missing/expired license, the Broker has reverted to 'file system'. This means no communication with the CD DB will be made -- for Custom meta this is a no go;

The last 3 errors will be somewhat present in a log file. So make sure you have the log level debug enabled and look for any stack traces in the cd_core and cd_broker logs.

Last but not least, make sure your website app-pool is unique to the Tridion website (do not reuse in other website). Check the .net version used (recommend 4.0) and check the user running it (recommend Network Service).
