Re: [equinox-dev] Cannot get the framework extension, org.eclipse.equinox.weaving.hook, to work in OSGI

Hi!

I think if you start the OSGi runtime from command line, you need to add the framework extensions (the weaving hook on this case) to the classpath when you launch the VM. So not just "java -jar" but "java -cp". What happens if you try this?

Cheers,

Hey Martin,

I just recently found this link, http://wiki.eclipse.org/JDT_weaving_features, which I believe details the classpath setup code you are referring to (correct me if I am wrong). I unfortunately still can't get the hook working with the system bundle. Here is what my config.ini looks like:

osgi.clean=true
osgi.frameworkClassPath=file\:/home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld/org.eclipse.osgi_3.4.0.v20080605-1900.jar,file\:/home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld/org.eclipse.equinox.weaving.hook_1.0.0.200808061839.jar

osgi.framework.extensions=org.eclipse.equinox.weaving.hook
aj.weaving.verbose=true
org.aspectj.weaver.showWeaveInfo=true
org.aspectj.osgi.verbose=true


All my bundles are in /home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld. My config.ini is in /home/djkasht/workspaceBlueprint/EquinoxAspectsHellowWorld/Configuration. I am not sure what else I could be doing wrong at this point and I must be close to figuring out this problem :) ________________________________________ From: equinox-dev-bounces@xxxxxxxxxxx [equinox-dev-bounces@xxxxxxxxxxx] On Behalf Of Martin Lippert [lippert@xxxxxxx] Sent: Wednesday, June 23, 2010 3:50 PM To: Equinox development mailing list Subject: Re: [equinox-dev] Cannot get the framework extension, org.eclipse.equinox.weaving.hook, to work in OSGI

Hi Daniel,

if I remember this correctly you need to put the org.eclipse.osgi bundle
AND the framework extension bundles on the classpath if you start the
runtime the way you do it.

(The exception you mention indicates that the framework extension is not
installed correctly.)

HTH,

I have been trying very hard to get the Equinox Aspects Hello World project run correctly outside of Eclipse, just using a custom config.ini and the Equinox shell. I believe the last thing holding me up is that the weaving.hook fragment bundle is not hooking into the system bundle. I have all the files from the plugins folder of the Hello World demo in the same folder as my system bundle and I have the hello and hello.aspects bundle in the same folder. My config.ini is in the ./configuration folder. It is a simple setup and there shouldn't be a co-location problems with the hook bundle. I'll post my config.ini below.

Config.ini:

osgi.clean=true
org.aspectj.osgi.verbose=true
eclipse.ignoreApp=true
aj.weaving.verbose=true
org.aspectj.weaver.showWeaveInfo=true
osgi.bundles=org.eclipse.equinox.weaving.demo.hello.aspects, org.eclipse.equinox.weaving.aspectj_1.0.0.200808061839.jar, org.aspectj.weaver_1.6.1.20080703120000, org.aspectj.runtime_1.6.1.20080703120000, org.eclipse.equinox.weaving.demo.hello
osgi.framework.extensions=org.eclipse.equinox.weaving.hook





I set the framework extension correctly right? Also, here is how I start the Equinox shell. If I enter start 3 I get an error, java.lang.NoClassDefFoundError: org.eclipse.equinox.service.weaving.IWeavingService

djkasht@zaius:~/workspaceBlueprint/EquinoxAspectsHellowWorld$ java -jar org.eclipse.osgi_3.4.0.v20080605-1900.jar -console -Dosgi.framework.extensions=org.eclipse.equinox.weaving.hook
