Hi,
We'd like to reopen this topic for consideration.
Old topic: http://marc.info/?l=jibx-users&m=117866534917771&w=4
We have a nearly identical problem/situation, and our question is two-fold:
* Are there plans to implement the functionality discussed in the above topic?
* Either way, we'd like some advice on a problem with our workaround(described
below)
The Situation:
We have a number of common objects(Organization, Person, etc) in one project.
These objects have not been compiled in jibx.
We have multiple implementations of a common Message interface(Let's say ImplA,
ImplB, etc), each with its own binding file, and each in its own project. All
implementations use the common objects as sub-elements in different
configurations throughout the xml.
When we receive a Message of a certain type, we load the appropriate binding,
and map our xml.
Due to the limitation discussed in the above topic, we've done the following
workaround:
To build any Message Implementation ImplX:
* The common objects' packages are copied into ImplX's project
* ImplX's project is built using the jibx bindings.
When all is said and done:
* We have ImplA.jar, ImplB.jar, etc
* Both jars contain, among other classes, a bindingfactory and jibx-bound
objects(including common objects).
* If the jibx-bound common objects' .class files are decompiled, one can see
that they differ only by one thing: a string referencing the particular
bindingfactory.
At Runtime:
* all ImplX.jar files are on the classpath
* If a message of type A is encountered, everything works fine.
* If the next message encountered is of type B, the common objects from class
A are still loaded, and the mismatch causes the following error(edited to
indicate [ImplA/ImplB]):
java.lang.NoSuchMethodError:

* It works the other way around: If B is the first message type encountered,
B will work, while A fails with the same error
Thanks in advance for any help,
