Having some problems...

[Gauthier]

Hi there,

I'm working on an OSGi project and I would like to use Tapestry-OSGi
(very good idea to implement this framework onto OSGi) but I have
encountered some problems. It works very well inside Eclipse (your
example or my app) but outside Eclipse it gave me this error:

org.osgi.framework.BundleException: Exception in
org.extwind.osgi.tapestry.firstpage.internal.Activator.start() of

Could you explain me why it doesn't work ?

Thanks for your help.

This means osgi-service [org.extwind.osgi.tapestry.ComponentService] has not been registered.

 

Check if (only) all of the following bundles are in state [ACTIVE]

 

Framework is launched.

id State       Bundle
0 ACTIVE      org.eclipse.osgi_3.4.2.R34x_v20080826-1230
1 ACTIVE      org.extwind.osgi.bundles.commons.logging_1.0.4.v20080605-1930
2 ACTIVE      org.extwind.osgi.equinox.http.jetty6_1.0.0
3 ACTIVE      org.extwind.osgi.tapestry_5.0.18
4 ACTIVE      org.extwind.osgi.bundles.mortbay.jetty6_6.1.17
5 ACTIVE      org.extwind.osgi.bundles.javax.servlet_2.5.0

12 ACTIVE      org.extwind.osgi.tapestry.firstpage_1.0.0

osgi>

By the way, configuration file META-INF\extwind\component.xml has been introduced for component bundle definition,  to take the place of any codes for tapestry-services registry in Activator of bundle, and a sample OSGi-Console is in programming, check it in svn.

To be surprised,to wonder,is to begin to understand.

Hi,

first of all, thanks a lot for your help :-)

That's exactly what I have in my OSGi console (even with an another
version of Equinox).
The previous-published error is due to this line of code:

ServiceReference sr = context.getServiceReference
(org.extwind.osgi.tapestry.ComponentService.class.getName());

So it confirms that my service is not registered but I don't
understand why.

Regards,

Service[org.extwind.osgi.tapestry.ComponentService] was published by bundle org.extwind.osgi.tapestry, used to register component bundle's root package into tapestry, which as the definition of context-param "tapestry.app-package" in web.xml.

 

Therefore the exception you encountered is probably caused by some errors bring the state of bundle org.extwind.osgi.tapestry_5.0.18 out of ACTIVE.
