Hello everyone,

 

EclipseLink needs to do some form of byte code enhancement/manipulation to provide support for lazy loading of one to one and one to many relationships for example. I am wondering if multiple products can be used that also need to do some form of byte code enhancement/manipulation, in an environment in which EclipseLink also exists? E.g. I would like to use AspectJ to advise some domain model classes that are JPA mapped via EclipseLink. Thus, AspectJ would need to do some byte code enhancement as would EclipseLink.

 

Is it known that this kind of thing would work? Could AspectJ weave first and then have EclipseLink weave, or vice versa, and would the resulting byte code honor the weaving that the first pass of weaving produced?

 

Regards,

 

Doug Gschwind

I'm currently having trouble deploying the osgi bundles with spring on the spring dm server platform.
It seems to be due to the osgi manifests not containing version information. 
It would seem spring has an optional import on versions 1 through 2. 

And since there isn't version info in the 1.1-M2 manifests, it's failing to be imported.  [What I've been told]

For anyone interested, here's the thread on springsource's forums.

Hi, Argh! I am trying to map a composite object into the parent record like documented here: http://wiki.eclipse.org/Introduction_to_XML_Mappings_(ELUG)#XML_Composite_Object_Mapping I have an Address element, and I'm trying to map the "Line" elements inside it to another object called "AddressLine". This is not working. The object "addressLine" is always null. My XML looks like: <Address ...> <AttentionOfName>Jane Doe</AttentionOfName> <CareOfName></CareOfName> <LineOne>101 Main Street</LineOne> <LineTwo>Apt 514</LineTwo> <LineThree>P.O.

So why doesn't this work? I saw the one note in the documentation that said "The nodes mapped to by the composite object must be sequential. " I am not 100% sure what this means, but I did make sure that all the nodes in Address and AddressLine are in the right order. In addition, I debugged into this but can't figure out why the "." mapping to AddressLine is never used. The eclipselink.moxy.test project uses this, so it looks like this is definitely supposed to be supported. But I want to do this with XML, not with code. Can someone tell me what is wrong with this mapping?

Hi Shaun,

Can you clarify this a little?  What is "thisClass"?  Is that the model
object class?  My setup is that I have one bundle for the model classes and
one bundle for some helper code that calls EclipseLink.  I don't think that
I can pass the helper bundle's classloader into EclipseLink and have
EclipseLink be able to see my domain classes.

Thanks!

Hi Polly,

You need to give MOXy a classloader that can see your domain classes. Try something like:

ClassLoader classLoader = thisClass.getClassLoader();
JAXBContext jaxbContext = JAXBContext .newInstance("examples.jaxb.model", classLoader);

Hi,

We've been trying to get EclipseLink MOXy to work in an OSGi environment
in
Equinox, and we found that in order to allow EclipseLink to instantiate
our
model objects, we need to set up a Buddy Policy. 

We had to modify the EclipseLink manifest to say:
Eclipse-BuddyPolicy: registered

Then we edited the bundle containing our model objects to say:
Eclipse-RegisterBuddy: org.eclipse.persistence.core

This works, but I don't like tweaking files that belong to a third-party
library.  It seems like everyone that uses Equinox would need the
BuddyPolicy.  So will you be willing to add the "Eclipse-BuddyPolicy"
entry
to the EclipseLink manifest?  Or are we doing something wrong?  If
there's a
better way to solve this problem, please let me know.

Thanks!
Polly

You need to provide the JAXBContext with a classloader that can see the model classes. If your utility bundle creates the context then you're going to have to pass it a classloader.
