Subject Re: Help with Camel JAXB (SMX4 + Camel 2.1.0)
Date Tue, 23 Feb 2010 09:03:04 GMT

I cannot easily because I have code that is bound to jdk1.6. Do you think
that uninstalling the jaxb-impl-2.1.12 bundle and adding com.sun.xml.bind.v2
to the org.osgi.framework.system.packages variable would do ?
