Re: [GeoNetwork-users] How to add schema template in geonetwork 2.2.0

[crayco <cr...@gm...>]

Thank's a lot!!!
The tutorial is now up to date. 

For the null pointer exception raised in metadata.insert, did you try to
trace which line in the java source code of metadata.insert that generates
the null pointer exception ? Could help to trace where the problem comes
from.

If you customize the "template.xml" file (at the very first step, or later
on), make sure index-fields.xsl and schema.xsd reflect those changes and
ViceVersa. Otherwise, geonetwork won't be able to index or search your
metadata. Many mistake come from having very small differences in the tags
name in schema.xsd, index-fields.xsl and template.xml.

It is really hard to debug schema creation, but keep up posting your
comments and findings. I spent 1 full time month last year to understand
schema creation and writing this tutorial... I it's still hard for me to
debug. I wish to make this tutorial as complete as possible so others don't
need to spend a month to insert a schemas.

cheers.
