can you tell us which version of Felix you are using, ie. 0.8.0 or 1.0.1? as well as how you're starting Felix - for example 'java -jar bin/felix.jar' the manifest file is > > Bundle-Name: English dictionary > Bundle-Description: A bundle that registers an English dictionary service > Bundle-Vendor: Apache Felix > Bundle-Version: 1.0.0 > Bundle-Activator: example.dictionary.Activator > Import-Package: org.osgi.framework FYI, this is an R3 manifest: ie. it doesn't contain a Bundle-SymbolicName or Bundle-ManifestVersion:2 - however, Felix should still be able to install and start it (the current OSGi spec is R4.1) I created a bundle with the same manifest and it starts using Felix 1.0.1 and there is nothing special in example.dictionary.Activator (It is a > copy of the example) > > > I'm a starter, and I'm so upset to meet the problem. I am using JDK6 if you're new to OSGi then you might want to try Neil's OSGi tutorial: http://neilbartlett.name/blog/osgi-articles or you could look at using Pax-Construct to generate example bundles: http://www.ops4j.org/projects/pax/construct this will use the bundleplugin to generate and verify the OSGi manifest: http://felix.apache.org/site/maven-bundle-plugin-bnd.html 2 Is that the contexts in each bundle activator's start method are > different? yes, a different BundleContext will be passed to each bundles' start method from the spec: "A BundleContext object represents the execution context of a single bundle within the OSGi Service Platform" 3 How to install a bundle in program without typing command in the shell. use a deployment service - for example Felix has a GUI shell, but you need to compile from trunk ( https://svn.apache.org/repos/asf/felix/trunk/shell.gui) alternatively Knopflerfish has a HTTP bundle for installing other bundles: https://www.knopflerfish.org/svn/knopflerfish.org/trunk/osgi/bundles/http/httpconsole/readme.html or you could use Eclipse/PDE with the Pax-Cursor provisioning plugin: http://wiki.ops4j.org/confluence/display/ops4j/Pax+Cursor http://wiki.ops4j.org/confluence/display/ops4j/Pax+Runner this lets you deploy bundles to all the major open-source OSGi frameworks HTH --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > -- Cheers, Stuart
