Having the same issue, while trying to validate a persistence.xml when running the ejbdeploy command in WebSphere. Had to set the ignore errors flag on. Don't like it, but it's the only way I could get past this problem. You will probably have to somehow turn off validations or ignore the errors.
Yeah I'm trying to tear down the validation... but it's a little bit tricky if you search JSF and validation^^
So if there is anybody how knows how to turn off the JSF Validation, please let me know!
I'm useing IceFaces 2.0, PortletBridge on Liferay 6.0.6 and that all runs on a JBoss 5.1GA
