P.S.:
AppRegistration.update(Dictionary properties) is never called, but don't know why and when it should be called.

Hi Chris,

thanks for your approach to bring together Vaadin and OSGI.
I'm using you Vaadin Addon (1.0.1) within Eclipse and Equinox, which runs fine.

Is there any reason, why the AddOn version is 1.0.1, but the repository contains 2.0.0 for quit a lot of months now?
I'm currently do some testings with v2.0.0 but with no luck. I thought, the only thing to change is the factory name, which has to look like in Peter Kriens implementation (component.factory=com.vaadin.Application/myAppName)?!

After debugging a while (I'm not much of an OSGI guy) I found out that the component gets registered
-> context.registerService(ManagedService.class.getName(), config, properties);
but the Vaadin application is never called.

Any hints or tricks?

Besides, the property isn't set correctly, because of using the full alias which is set to (/myAppName).
-> properties.put(Constants.SERVICE_PID, "com.vaadin.Application." + alias);
I've fixed it by setting
alias.substring(1).

Best regards,
Erik

copying widgetsets to and exporting from fragment bundle isn't all that must be done:

Hi Chris,
I like your way to combine vaadin and osgi. I started based on Kai's tutorial and all workled well until I tried to add some Vaadin add-on's.
Is there anywhere a guide or some doc how to solve this ?
tried it with a very small add-on 'QRCode', copied the jar to an Eclipse EE+Vaadin installation, compiled the widgetsets and then copied the VAADIN.widgetsets to a Fragment Bundle in my Eclipse-OSGI installation. tried different ways where and how to add and export the qrcode.jar, but getting always error in browser
fi.jasoft.qrcode.QRCode(NO CLIENT IMPLEMENTATION FOUND)
any idea what could be wrong ?
thx for your helpful bundles !

Brindy,

Thanks for this great app. It has helped me keep track of my money just as you advertised.

I am wondering if you are thinking of adding any other features - like an ability to export the data to a document/excel file in order to review the inputed budget?

Thanks again.

Chris,

I am playing around with Vaadin, Equinox & Jetty. When I try to use your org.vaadin.osgi bundle I get an Wiget in the browser saying: Failed to load the widgetset: /VAADIN/widgetsets/com.vaadin.terminal.gwt.DefaultWidgetSet/com.vaadin.terminal.gwt.DefaultWidgetSet.nocache.js?1293530932935

Any hints?

Thx

If in multi tier environments statics can easily be handled by apache without the need of having several bundles like staticRes by just using mod_expires.
This would be a more transparent approach

chris,

one more broken link, though - neil's blog has moved to http://njbartlett.name/ - you may want to correct that.
cheers!

2010-08-27T10:19:09.940+01:00

Although it seems stable enough, I just mean that many people might not like the idea of checking in source that would later be modified by an external jar at compilation time.

You would need to keep the appropriate Lombok jar in source control too, and ensure it was used during the compilation. Otherwise the class file might differ depending on what version of the Lombok jar you use to compile with.

You can get around this with their 'delombok' tool though.
http://projectlombok.org/features/delombok.html

I would check in 'delombok-ed' code which is then indistinguishable from hand written code and can be scrutinized and unit tested without additional processing.

2010-07-29T16:51:50.829+01:00

Hi Peter,

Adding widgets isn't easy as it requires an extra step at development time to generate some static resources using GWT.

The best I've come up with (so far) is making additional extra static resources available as a fragment of the Vaadin bundle, which my "StaticRes" servlet kind of acts as a proxy for, but like I say, I think static resources should be being served by a proper web server anyway so I'm not putting too much importance on this aspect of my implementation.

The Java part of the widget however, can be wrapped directly in your own bundle(s) or imported in the usual OSGi way (if packaged correctly). I need to play with this some more in an OSGi environment though, as so far I've only used 3rd party widgets when creating a WAR file.

I understand your motivations for wrapping the bundle. The developer/deployer could re-wrap / re-package the Vaadin bundle to minimise exports if they wanted and my approach would still work. :)

What are the downsides of exporting too much in to the container at runtime (even if you don't use it at development time)?

Cheers,
Chris

2010-07-29T16:33:40.512+01:00

The reason I wrapped the bundle is because it was exporting too much. In a modular environment you want to minimize exports and not show implementation. I also added a component that tracks the appropriate services.

However, the problem I got stuck on, and you seem to have solved, is how to add new widgets? The big missing piece in Vaadin for me was how to have a bundle contribute widgets. Do you see an opportunity for this?

2010-07-28T22:26:17.274+01:00

In fact, didn't understand my own code! The properties associated to component factory are passed in to the servlet as init parameters so each app can have it's production mode specified individually.
