Re: [eclipselink-dev] Question on config.ini in JEE package about equinox.weaving 
I'm not sure about the build system ... if it can be told not to include 
this or all osgi.framework.extensions. 

Do you know ... will this cause some "harm" if there in config.ini? Such 
as a performance impact? Or, is it just not needed in the IDE environment? 


I've opened bug 278469 to continue the discussion in more detail. 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=278469

Thank you very much,

Hi David,

   The org.eclipse.persistence.equinox.weaving bundle is a framework 
extension that supports byte code weaving of JPA entities.  As you can see 
on this example  page, it is only functional if installed correctly.  It 
is intended to be used as a framework extension by developers in their 
Equinox applications.

   From looking at the info below it looks like the EPP build system is 
looking at the manifest of this bundle, detecting that this is a framework 
extension, and then generating the line in the config.ini:
osgi.framework.extensions=reference\:file\:org.eclipse.persistence.jpa.equinox.weaving_1.1.2.v20090526-r4309.jar


    Is there a way to tell the build system not to do this?

        Shaun

you watches that list, right? 

But, I'm just wondering, briefly, what this jpa.equinox.weaving bundle 
does and how it might change platform behavior in the Java EE IDE. Should 
it _really_ be there in config.ini? 

Thanks,

At least I can answer where it was taken from.

If you look into the content.jar (content.xml) of the Galileo Staging 
repository, you will find some install instructions:

    <unit id='org.eclipse.persistence.jpa.equinox' 
version='1.1.2.v20090526-r4309' singleton='false'>
...
          <instruction key='manifest'>
            Bundle-Vendor: Eclipse.org - EclipseLink 
Project&#xA;Bundle-SymbolicName: 
org.eclipse.persistence.jpa.equinox&#xA;Bundle-ManifestVersion: 
2&#xA;Bundle-Version: 
1.1.2.v20090526-r4309&#xA;Bundle-RequiredExecutionEnvironment:

org.eclipse.osgi.baseadaptor;resolution:=optional,org.eclipse.osgi.baseadaptor.bundlefile;resolution:=optional,org.eclipse.osgi.baseadaptor.loader;resolution:=optional,org.eclipse.osgi.framework.adaptor;resolution:=optional,org.eclipse.osgi.internal.baseadaptor;resolution:=optional,org.eclipse.persistence.jpa.equinox.weaving;resolution:=optional&#xA;Specification-Vendor: 

Eclipse.org - EclipseLink Project&#xA;JPA-Initializer: 
org.eclipse.persistence.internal.jpa.deployment.osgi.equinox.EquinoxInitializer
          </instruction>

So it will be best to ask the EclipseLink project.

I notice this line in our config.ini

osgi.framework.extensions=reference\:file\:org.eclipse.persistence.jpa.equinox.weaving_1.1.2.v20090526-r4309.jar

I'm wondering what that is ...

and how did it get in there?
In the sense of; how'd it get in there without me be aware of it?
Is it "manually" added somewhere? Or is it "picked up" automatically from
somewhere?
