Update the embedded field

Question

we have following problem:
class A has class B as embedded attribute.
If we write:
tx1: a = readA();
tx2: a.b.setName("new Name"); makePersistent(a)
the changes in field "name" will not be saved.
If we write:
tx2: a.b = new B("new Name"); makePersistent(a)
the field "name" will be updated !
What is wrong with a.b.setName("new Name"); ???
thanks

Pretty much like you described.
Normally, if you move your update site, people who bookmarked it would also
be afected.
You could keep site.xml at the old location and have everything else moved.
Make use of the <archive> element in site.xml to point to jar files at other
locations.
Even better, redirect from old site to new site, using your web server
functionality.
