Hello everyone

We are developing an OSGi based webapp with STS and Virgo. The web app
worked fine on Virgo within STS so far.

I now checked out a fresh copy of the project and tried to set is up in
eclipse again. Since there is no proper way to configure a maven based
eclipse project out of the box, I did it by hand. I added the OSGi
Bundle Nature and added the Dynamic Web Module facet.

Now when I start up the web app by dragging it onto thy virgo 3.0.0.M3
instance in STS, the webapp starts fine, but when I access it, I only
get back 404s. When I look at the log files, I see the following lines:

[2011-03-25 16:22:10.480] TCP Connection(10)-127.0.0.1
org.eclipse.virgo.medic.eventlog.default DE0004I Starting bundle

....

[2011-03-25 16:22:10.673] start-signalling-3
org.eclipse.virgo.medic.eventlog.default WE0001I Started web bundle
'net.junisphere.eranger.ui.web' version '0.0.1.SNAPSHOT' with context
path '/er'.

It seems as if this web bundle is not recognized as a spring dm bundle
("Non-Spring DM powered bundle").

What am I missing or what do I have to configure in STS to make the
webapp work again?

Best regards,
James

Hi James!

Sorry for not coming back to you earlier. Do you still have the problem?

I am not sure I understand the problem correctly. Does your project have a MANIFEST.MF file? (maybe generated by Bundlor). Typically there is nothing special needed to be recognized as a Spring-DM bundle (as far as I know).

In case you still have problems, it would be great to get an example project that can be used to reproduce the problem. I am sure we will find out what is missing here.

Cheers,
-Martin

I could solve the problem.
When checking out a fresh copy of the project, we have to set the
eclipse project facets and natures manually.

I added the "Dynamic Web Modules" facet to the web project, but forgot
to set the content directory to src/main/webapp in the "Further
configuration available..." dialog. So the content directory was set to
WebContent, which was empty of course. This also explains why the bundle
have not been recognized as a spring dm powered bundle, because the
config files were not present.

I had to change the path of the content directory from "WebContent" to
"src/main/webapp" in the .settings/org.eclipse.wst.common.component file:

....
<wb-resource deploy-path="/" source-path="/src/main/webapp"/>
....

Best regards,
James
