Hello Christian,
your BaseX database is with RESTXQ on very interesting road towards xquery
based web applications
and the Unit Module puts XQuery into a new software engineering perspective!
While this application field naturally leads to a client/server architecture
we have an expanding row of usages of BaseX in embedded mode, see for
example [1].
At the moment the Basex 7.7 still has basex-xqj-1.2.3.jar.
Question: Are there plans to update to the upcoming (?) version
basex-xqj-1.3.jar?
With best regards,
Andreas

Hello Charles,
thank you for your detailed answer.
Your answer enables us to make an "informed decision".
We have been interested in a bug-fix in that is contained in BaseX 7.3. But
there
is a logical workaround for this.
This workaround is better than to dismiss XQJ now and change the
architecture
of the software.
With our answer we can wait with an update of BaseX until XQJ 1.3 is there,
because
it will come in the "near future".
With best regards
Andreas
Hi Andreas,
A local / embedded version of BaseX XQJ, (i.e. no Socket connection)
is planned for BaseX XQJ 1.3
The primary aim will be to have as much compatibility as possible with
the client/server based version [1]
This is not a quick job and I wouldn't expect anything soon. Perhaps
in the next 2 months or so.
In the meantime, I suggest that you at least test your software
against the Client / Server XQJ driver, because although unlikely,
there "may" be differences in behaviour between the the version of
BaseX XQJ driver you're currently using and the XQJ.NET
implementation.
If your code needs to change as a result of switching drivers, you
will get foresight on those changes in advance.
Kind Regards,
Charles

Hi Andreas,
as you correctly observed, the old XQJ implementation has been
discontinued, and our current XQJ implementation is based on the
client/server architecture. We already thought about providing a local
version as well. The (closed source) implementation would be
completely up to Charles Foster, and I imagine it could take some time
to finalize, so please don't expect any short-term miracles. Charles
might give you more details just in case.
Christian

Hello BaseX-Team,
this mail informs you about the further steps that have been done in this
point:
1. Search for source code
I have not been able to find the source code for basex-xqj-1.2.3.zip. A
question would be if the source code
for this module is available. (Just find the answer to the question "in the
source code").
2. JavaDoc
The JavaDoc says:
"This implementation internally creates Socket connections with a BaseX
Server" see [1]
From point 2. I would conclude that it is not possible to use a
local/"embedded" database with the new XQJ.
With best regards,
Andreas

Hello BaseX-Team,
it is great to see the vibrant evolution of your BaseX development.
We have a component that is at the moment on (the now outdated) BaseX
7.0.2 and the
component uses
* local databases (to make it as independent as possible from the
environment where it runs)
* and XQJ.
Now we want to migrate this component to BaseX 7.3/BaseX 7.5.
But all the examples of the new (1.2.x) version of basex-xqj use the
client server architecture,
and it is stressed in the documentation:
"BaseX XQJ communicates with a BaseX Server via a client-server
architecture,
where BaseX XQJ acts as the client and the BaseX XML Database acts as the
server.", see page 3 in [1]
Question:
Can BaseX 7.3/BaseX7.5 access a local database with XQJ?
With best regards
Andreas
