Hi Ted,
It turns out that the PDE launcher works fine. You do have to
specify -Dosgi.framework.extensions in the launch configuration but the
biggest restriction is that org.eclipse.osgi, the Equinox bundle, has
to be co-located with any framework extensions [1] like EclipseLink
weaving. If you're working with the Java EE Galileo distribution then
the EclipseLink bundles are installed in your Eclipse IDE install's
plugins folder along with Equinox. You can always install the
EclipseLink bundles into Eclipse from the Galileo or RT update sites to
achieve this configuration.
Hope this helps,
Shaun

Shaun,
It just occurred to me what a lousy job I did explaining what
I'm doing. I'm actually trying to get this all working in the Eclipse
PDE, per the PDE OSGi tutorial. I came across a post from you (forum
message #482226)
indicating that this can work with weaving. I'm hoping that the
behavior I'm observing is something someone has seen before. Based on
your feedback - perhaps I need to launch differently.

Hi Ted,
I hate to be pedantic but you have to follow the wiki instructions
_very_ closely. Various people have confirmed the instructions work as
written. The last person who posted on the newsgroup having trouble
with the example had not followed the wiki example to the letter. For
example, if you're trying to boot Equinox with java -jar then it
definitely won't work. When started this way, Equinox processes adaptor
hooks before it has loaded the EclipseLink framework extension--very
frustrating. So far I've had success using the Equinox launcher
framework as described on the wiki and with the Spring OSGi test
framework which starts Equinox and loads all bundles programatically.

I've tried a few times to get dynamic weaving working following the
example application [1]
The application functions fine, but without any weaving which I tested
as recommended:
Helper.classImplementsInterface(Person.class, PersistenceWeaved.class)
With some use of the debugger it appears to me that hookconfigurators
provided by
org.eclipse.persistence.jpa.equinox.weaving are not being registered
in the HookRegistry.
The weaving bundle fragments are resolved as seen in the following
osgi short status:
0 ACTIVE org.eclipse.osgi_3.5.0.v20090520
Fragments=4
1 ACTIVE org.eclipse.equinox.common_3.5.0.v20090520-1800
2 RESOLVED org.eclipse.persistence.jpa.equinox_1.1.2.v20090612-r4475

Fragments=2
9 ACTIVE myplugin_1.0.0.qualifier
10 ACTIVE org.eclipse.persistence.core_1.1.2.v20090612-r4475
I have specified the vm argument:
-Dosgi.framework.extensions=org.eclipse.persistence.jpa.equinox.weaving
But presumably that wouldn't impact the registry of the available
hookconfigurators.
Is there anything that I maybe did wrong that could be preventing the
identification of the
hookconfigurators? Am I on the wrong track?
Thanks - Ted
