RE: [Babeldoc-devel] retrieving a document from the journal

Bruce,
Thanks for the information on the local configuration.
I have found the demons causing my No suitable driver error.
java.sql.DriverManager attempts to load the drivers in the jdbc.drivers
system property explicitly using the system class loader, whereas the
classes12.jar for oracle was not in my system classpath. What was confusing
was that I could load the class, using Class.forName(), or call
DriverManager.registerDriver() using a new instance of the oracle driver,
which made things work, because the babeldoc classloader is loading it. So
the answer is to explicity add it to the classpath.
Also, the line that's missing from query.properties that makes the oracle
journal able to store documents is:
journalSelectBlobForUpdate-oracle=select jrn_data from journal where
jrn_log_id=? and jrn_log_step=? for update
Dejan mentioned in the Open Discussion forum to me that you might have
written a pipeline stage that uses the HttpClient library... Is that true?
Sincerely,
Jonathan Leech

Hmm,
Yes, that should do it. Are you sure its in the classpath?
But, what I mean about local configuration path is this:
You override the babeldoc configurations (as given in the babeldoc module
jar
files) by setting the BABELDOC_USER environment variable to a configuration
directory of your own. This is always takes precedence over whatever is
built into babeldoc. So, a practical example, in windows:
1. Your babeldoc is installed in c:\babeldoc, and therefore the
BABELDOC_HOME=c:\babeldoc
2. Your configuration data is stored in c:\work, and therefore the
BABELDOC_USER=c:\work
3. Create a subdirectory c:\work\env
4. Create a file in there called config.properties. Set the property (or
whatever properties) needed for your code to run.
Try this, let me know.
regards,
Bruce.
