First Slices Project in Eclipse

[snagogo]

Hello,

I think I'm facing a slices beginners problem...

After installing the Slices Subsystem (slices-1.0.0.CI-39) as discussed here, the dm Server (v2.0.1.RELEASE) starts up like expected saying the slices plan was started correctly:

[2010-06-02 16:24:53.557] system-artifacts             <DE0000I> Installing plan 'com.springsource.osgi.slices' version '1.0.0'.

Then I wanted to rebuild the menu bar example by myself using eclipse 3.5.

So this is what I did (as I always do developing dm Server bundles with web functionality):

- Create Dynamic Web Project "slices.host"
- Add OSGi Bundle Project Nature via Spring Tools Option
- Enable Bundle Classpath Container via Spring Tools Option

- Edit src/main/webapp/MANIFEST.MF by changing the copied content of animal.menu.bar template.mf:

Manifest-Version: 1
Bundle-SymbolicName: slices.host
Bundle-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: My Host
Web-ContextPath: /hostbar
Import-Bundle: 
 com.springsource.org.apache.taglibs.standard;version="[1.1.2,1.3)",
 com.springsource.javax.servlet.jsp.jstl;version="[1.1.2, 1.1.3)",
 com.springsource.osgi.slices.api;version="[1.0,2.0)"
Import-Package: 
 com.springsource.osgi.slices.core;version="[1.0,2.0)"

- Copy the folders 'images', 'styles', 'WEB-INF' and the files 'bottom.jsp', 'index.jsp', 'top.jsp' from animal.menu.bar webapp folder to slices.host webapp folder

Adding this bundle to the dm Server within Eclipse works just fine and I can access the page at http://localhost:8080/hostbar/.

[2010-06-02 16:25:57.542]  TCP Connection(4)-127.0.0.1 <DE0000I> Installing bundle 'slices.host' version '1.0.0'.

[2010-06-02 16:25:58.144] start-signalling-2           <ME0001W> A message with the key 'SL0000I' was not found. The inserts for the message were '[/hostbar]' 
[2010-06-02 16:25:58.151] Thread-3                     <WE0001I> Started web bundle 'slices.host' version '1.0.0' with context path '/hostbar'.

Then I did nearly the same for creating a Slice:

- Create Dynamic Web Project "slices.slice"
- Add OSGi Bundle Project Nature via Spring Tools Option
- Enable Bundle Classpath Container via Spring Tools Option

- Edit src/main/webapp/MANIFEST.MF by changing the copied content of cat.menu.item template.mf:

Manifest-Version: 1.0
Bundle-SymbolicName: slices.slice
Bundle-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: My Slice
Slice-Host: slices.host;version="[1.0, 2.0)"
Slice-ContextPath: /barentry
Import-Bundle: 
 com.springsource.org.apache.taglibs.standard;version="[1.1.2,1.3)",
 com.springsource.javax.servlet.jsp.jstl;version="[1.1.2, 1.1.3)",
 com.springsource.osgi.slices.api;version="[1.0,2.0)"
Import-Package: 
 com.springsource.osgi.slices.core;version="[1.0,2.0)"

- Copy the folders 'images', 'WEB-INF' and the files 'index.jsp' from cat.menu.item webapp folder to slices.slice webapp folder
- Copy and edit slice.properties to META-INF folder of slices.slice

But when I add this project to the server I'm only receiving the following output and nothing else happens.

[2010-06-02 16:27:02.825]  TCP Connection(6)-127.0.0.1 <DE0000I> Installing bundle 'slices.slice' version '1.0.0'.

Does anyone has a hint what's wrong?
The sources are attached as .zip but packaged as .7z please change after download.

I also tried to export the projects as .war files (using Eclipse: Export - WAR file) and then getting them started via the admin console of dm Server.
Again, slices.host.war works fine, but when I try to upload slices.slice.war I get this exception:

HTTP Status 500 -

Hello again,

today I tried out my projects using dm Server 2.0.0.RELEASE and they are working.

So I guess there is a problem with 2.0.1.RELEASE...

Please be aware that slices is only a prototype and we make no guarantees about it running on dm Server or Virgo. This was made clear when slices was first mentioned in a blog and nothing has changed since.
