Oded, which version is that?

On my setup it works with:
https://rhevm31.demo.redhat.com/api?rsdl

Meaning api?rsdl and not api/?rsdl
Comment 3 Oded Ramraz 2012-09-23 20:45:59 UTC 
When browsing to /api?rsdl and then /api/?rsdl everything works fine.
When staring with /api/?rsdl I get this exception ( you might need to restart ovirt-engine service in order to reproduce it ).
BTW both https://aqua-rhel.qa.lab.tlv.redhat.com/api/?schema and https://aqua-rhel.qa.lab.tlv.redhat.com/api?schema ( for retrieving XSD file ) works fine.
I except /api/?rsdl link to work fine or alternately to get 404 error, but not 500 server error.
Comment 4 Michael Pasternak 2012-09-24 06:39:00 UTC 
trailing slash in /api/?rsdl is incorrect, but 500 should not occur
Comment 5 Michael Pasternak 2012-09-24 06:40:50 UTC 
btw correct url is /api?rsdl
