BXMLSerializer, can I specify a classloader?
Hello all,
I'm running into issues trying to load my pivot window into a swing
application. Some background,
since pivot 2.0 can load components into a swing application, I've been
trying to integrate pivot into a netbeans platform application.
Only been at it a couple of hours but I'm stuck on an class loader issue.
Basically, because I have pivot wrapped in separate module it's classloader
can't references classes in any modules that depend on it. See here:
http://bits.netbeans.org/dev/javadoc/org-openide-modules/org/openide/modules/doc-files/classpath.html#loader-hier
I looked briefly in the docs but I'm not sure if I missed a readObject()
signature that will allow me to pass in the classloader to use when
de-serializing.
Thanks for any info/help here.

Updated the ticket with some info.
Basically by using the other signature for Class.forName, I was able to get
around the problem I was having.
It doesn't address the issue of needing to use a custom classloader but
because of the module system in
the platform, things work.

Hi to all,
some year ago I had the same problem inside a Java Enterprise webapp,
where in a custom bean factory I need to load classes in a different
layer of the EAR, so (when needed) passing the classloader instance of
the caller solved the problem.
I'll put some info in the ticket.
Uh, of course this in a multi-layered app is a very good feature :-) ,
and probably not only in the BXMLSerializer but in any place where a
dynamic loading of classes is done inside Pivot, .. maybe later, so
BXMLSerializer is without doubt a good start for it.
Bye,
Sandro

Yup, looks good. Thanks.

I was going to suggest that you create a custom subclass of BXMLSerializer that overrides newTypedObject(), but that won't work - newTypedObject() takes a Class<?> instance, and you would need a String.

I haven't used JIRA before but I think I did it correctly:

That is an interesting problem. There's currently no way to pass a ClassLoader to BXMLSerializer. I was going to suggest that you create a custom subclass of BXMLSerializer that overrides newTypedObject(), but that won't work - newTypedObject() takes a Class<?> instance, and you would need a String.
Definitely something that should be fixed - would you mind creating a JIRA ticket for this?
Thanks,
