Dave Erickson commented on JCR-888: ----------------------------------- Thanks for the quick response. I found out that the issue was due to a custom JRE. When I used the default 1.4.2 and 5.0 JRE's from Sun, there is no longer an issue. I will close this ticket. > javax.jcr.NamespaceException: : is not a registered namespace uri > ----------------------------------------------------------------- > > Key: JCR-888 > URL: https://issues.apache.org/jira/browse/JCR-888 > Project: Jackrabbit > Issue Type: Bug > Components: core > Affects Versions: 1.2.3, 1.3 > Environment: Windows XP, Eclipse 3.1, JRE 1.4.2 and 5.0 > Reporter: Dave Erickson > > Using the first hops with both versions 1.2.3 and 1.3, the repository is > created successfully the first time it is run.
