Monitoring an XML file to trigger regeneration of ITD Metadata

[chanwit]

Hi all,

I am developing an add-on that will be monitoring some XML files and I'd like the add-on to trigger the regeneration of an ITD metadata. I tried to use file monitoring but it was unsuccessful. My questions are:

1. Is there a proper (right) way in Roo to monitor file change?
2. After the file change event occurred, how could I trigger the regeneration of an ITD metadata programmatically?

Thank you

Finally I've found steps to achieve these.

1. I have my metadataProvider to implements FileEventListener.
2. To trigger regeneration of my ITD metadataProvider, I call metadataService.evictAndGet(mid).
and call notifyDownstream(mid), where "mid" is a metadata identification string starting with "MID:".
