updating fragment bundles

[derekv <de...@yahoo.com>]

Lets say i have bundle A and fragment bundle B that is associated with bundle
A.
Lets say i am using the File Install service.
If i need to update a class in fragment bundle B can i simply drop the new
jar file in the folder and everything is taken care of.
Or do i need to perform some manual steps?
Does the host bundle need to do some type of refresh for it to pick up the
changed class?

I have been searching for some kind of documentation on the lifecycle of a
fragment bundle and how it relates to the host bundle but have not been able
to find anything.

File Install automatically refreshes if any bundles were updated or 
uninstalled. This should be sufficient to get the updated fragment to 
reattach to the host, but the simplest way to see is to try.

So does the File Install service refresh the host bundle automatically in
order for it to pick up the changes in the fragment bundle? Sure would be
nice if it did.

thanks.

Hi,
per specification:

"When an attached fragment bundle is updated, the content of the previous
fragment must remain attached to its host bundle. The new content of the
updated fragment must not be allowed to attach to the host bundle until the
Framework is restarted or the host bundle is refreshed. During this time, an
attached fragment will have two versions: the old version, attached to the
old version of the host, and a new fragment bundle that can get attached to a
new version or to a different host bundle.
"

This is fairly similar to performing any update. If a bundle is wired to 
some bundle, updating the target of the wire will not be seen by the 
source unless a refresh is performed. This is no different for packages 
or fragments.

So, to answer your question, you will need to refresh. However, I think 
File Install does a refresh automatically after an update.
