  • First Slices Project in Eclipse

    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:

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

    [2010-06-02 16:24:53.804] system-artifacts             <DE0001I> Installed plan 'com.springsource.osgi.slices' version '1.0.0'.

    [2010-06-02 16:24:53.894] start-signalling-2           <DE0005I> Started bundle 'com.springsource.osgi.slices.api' version '1.0.0.BUILD-20100309145748'. 
    [2010-06-02 16:24:54.071] start-signalling-2           <DE0005I> Started bundle 'com.springsource.osgi.slices.core' version '1.0.0.BUILD-20100309151201'. 
    [2010-06-02 16:24:54.078] start-signalling-2           <DE0005I> Started 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:

    Code:
    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/.

    Code:
    [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 16:25:57.658]  TCP Connection(4)-127.0.0.1 <DE0001I> Installed bundle 'slices.host' version '1.0.0'. 
    [2010-06-02 16:25:57.811]  TCP Connection(4)-127.0.0.1 <DE0004I> Starting bundle 'slices.host' version '1.0.0'. 
    [2010-06-02 16:25:57.818] Thread-3                     <WE0000I> Starting web bundle 'slices.host' version '1.0.0' with context path '/hostbar'. 
    [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'. 
    [2010-06-02 16:25:58.155] start-signalling-2           <DE0005I> Started bundle 'slices.host' version '1.0.0'.


    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:

    Code:
    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.

    Code:
    [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:

    Code:

    dm Server v2.0.1 source of the problem?

    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.
