Thanks Ed for the reference, each little piece sheds some light (and more
questions as well).
For the heck of it, I blindly threw in a "JbpmConfiguration.createSchema()"
statement in my code because, hey, it sounds promising...
Guess what, my errors went away and my logging shows a lot of insert statements
into what appear to be tables with names like JBPM_NODE, JBPM_EVENT, etc.
Did I do good?
Now, when I look at the (outdated?) jBPM 2.0 Deployment Doc, under
Configuration it describes 4 configuration mechanisms and some properties. One
of the properties is "jbpm.create.tables" and a possible value is
"only-if-not-present". The description is anonymous wrote : If applicable, jbpm
will create the the JBPM_ tables at startup if they are not present. The
generated ddl starts with dropping the tables and contraints, then creates the
tables, then adds the constraints.
Q: If I had had this property in my "jbpm.cfg.xml" file, would the schema have
been created automatically at first access?
To continue the discussion:
For my bare-bones test, my "jbpm.cfg.xml" file is empty, and the comment in it
says anonymous wrote : The default configurations can be found in
org/jbpm/default.jbpm.cfg.xml
| Those configurations can be overwritten by putting this file called
| jbpm.cfg.xml on the root of the classpath and put in the customized
values.
|
Q: Does that mean that jBPM first reads the default file, then reads the
"jbpm.cfg.xml" file and overrides any repeated settings, or does it mean that
if the "jbpm.cfg.xml" file is present, the default file is ignored?
Also, when I look in that default file, there is a comment in it that says
anonymous wrote : This configuration is used when there is no jbpm.cfg.xml
file found in the root of the classpath. It is a very basic configuration
without persistence and message services. Only the authorization service
installed.
| You can parse and create processes, but when you try to use one of the
unavailable services, you'll get an exception.
|
Two issues: 1) The first sentence seems to imply that the default file is
completely ignored when the "jbpm.cfg.xml" file is present -- implying you need
to copy any settings from the default file to the "jbpm.cfg.xml" if you want to
use them, and 2) the comment says "without persistence", but the file has
entries for persistence service and hibernate (see below).
Q: Is the comment correct that there is no persistence set up?
