Subject Re: CAS Curator - No metadata detected
Date Thu, 09 Feb 2012 02:52:51 GMT
Hi there,

Thanks for the feedback!

Hmm, are you getting any specific errors in your Tomcat logs when you get no metadata 
detected error? Also, can you verify that you have the following property set:


This should be set in your META-INF/context.xml file inside of the unpacked webapp, 
or inside of a specific context.xml file that you configure in Tomcat. A couple of questions:

1. what value is that path set to?
2. do you see a corresponding met file underneath org.apache.oodt.cas.curator.metAreaPath/mp3?
   - if the answer to #2 is "no", then that's why you are getting the "No metadata detected
error". It's not
exactly an error, it's just letting you know that there is no pre-computed metadata file that
has been 
generated, and thus it's not already there. To generate the met file, you click the "refresh"
button in 
the interface, which will run the mp3 extractor
    - if the answer to #2 is "yes", then that definitely is an issue that we can look at.

Let me know the answers to the above. Also thanks for the points to updates in the guide.
I'll open up corresponding JIRA issues and take a lead in getting those fixed!

When I select a Test.mp3 file, I get "No Metadata detected" error in the right pane (screenshot
attached). I do see mp3extractor in the drop down list.
