Hello BaseX folk,
I have just installed version 9.1.2 and am starting to learn BaseX in support of my post-cancer #PayItForward Bonus Round #CitizenScientist research in #DigitalHumanities and #MachineLearning. My goal is to "cut out the middleman" of writing intermediate JSON and XML fragment files in order to update the #MAGAZINEgts ground-truth storage file that I am developing for a digital collection of Softalk Apple magazine at the Internet Archive. With BaseX and its Python interface, I want to write new and updated document structure and content depiction metadata directly to a local copy of this ground-truth master file which will then be easily popped out of the database as an XML file for uploading to the Softalk Apple collection at the Internet Archive.
I hit a bump, reported to the Github Issue queue, where my Windows 10 installation can not open the BaseX GUI exe launcher. The work-around, as noted in my issue report, is to use the Getting Started advice to execute the jar directly. By creating a desktop icon that launches the execuable jar in the installation folder, the GUI launches as expected.
With that minor issue behind me, I am wondering why my attempts to connect to the server via localhost:1984 port does not work while everything is fine and dandy when hitting port 8984. Port 1984 returns an invalid HTTP response. (Note: Other ports that are not assigned to anything else return a connection refused, so this invalid response is not the same as the server not being there.)
If I keep a Powershell window open with the server running, every once in a while (after several minutes or more) the server throws this error:
java.lang.NullPointerException at org.basex.core.Context.perm(Context.java:252) at org.basex.core.Command.run(Command.java:250) at org.basex.core.Command.run(Command.java:143) at org.basex.core.cmd.Close.close(Close.java:54) at org.basex.server.ClientListener.close(ClientListener.java:232) at org.basex.BaseXServer$1.run(BaseXServer.java:157) at java.base/java.util.TimerThread.mainLoop(Timer.java:556) at java.base/java.util.TimerThread.run(Timer.java:506)
which may be related to port 1984 not responding, a firewall issue perhaps? Honestly, I don't see anything that looks like a BaseX process or service running in Task Manager (other than a generic 'Java(TM) Platform SE binary' process, and there is nothing that looks related in the Windows Firewall entries. I'm still investigating this here, but if anyone knows what is akimbo, I would greatly appreciate your advice.
Thank you... and looking forward to being a new BaseX community member. :-)
