Reposting Moving to Aries 1.0.0

[Ivanhoe Abrahams <iv...@gmail.com>]

Hi all

I have started moving my proof of concept aries project from version 0.3 to
1.0.0
However I now see the following exceptions

ERROR: Bundle org.apache.aries.blueprint.core [65] EventDispatcher: Error
during dispatch. (java.lang.ClassCastException:
org.apache.aries.blueprint.ext.impl.ExtNamespaceHandler cannot be cast to

Later on in the log output I see

These exceptions then result in my service which contains a persistence.xml
and a blueprint.xml file to fail with the following timeout exception

324028 [Blueprint Extender: 3] ERROR

Here is my blueprint.xml file of the service that fails with the timeout

</blueprint>

I am running my proof of concept on
- windows 7
- java 1.6
- Apache  Felix 4.0.2

Funny thing is that when I check the bundles using the felix webconsole,
all bundles have started fine and are active.
This all worked fine in 0.3 version of aries.

Any pointers will be appreciated.

Kind
Regards

Ivanhoe
