[basex-talk] JAVA xquery: accessing documents
Hello,
Normally (few basex-versions ago) I did:
session.execute("open main");
session.execute("xquery doc("users.xml")//users");
But now, this results in basex interpreting the doc()-path as relative
to it's home-directory thus cannot find the resource..
"xquery doc("main/users.xml")//users" gives the correct results.
Do we no longer open a database but writing the full path of the
document instead?
Whats the performance of this if accessing multiple documents of the
same database during runtime?
-regards,
jan

Excuse me.. In Germany we say "zu frueh gefreut"..
When running the query WITH ADMIN PERMISSIONS, it works.
When running the query with read/write permissions the same (not more
detailed) "interupted"-Exception shows up.

I can't figure out why but both of my problems are gone after updating
to version 8.6.1. - thank you.
(It would be helpful to know why to verify it is not an arbitrary
problem with my system..).
btw: Is there an issue with the latest basex web-app? I am not able to
log in (the field to specify the port is missing as well).

Jan
[basex-talk] Retrieve large amount of data from XML-resource
Hello,
i am getting an BaseXException when trying to get large amount of data from a
XML-resource with a JAVA-Client.
For example for a xml-file with the size of 79167874 ("FACTOR", as shown by the
web-gui) "session.execute(new XQuery("doc('db/file.xml')"));" will result in an
exception[0].
My assumption is that a timeout is exceeded somewhere.. so my next question is
how to properly set the timeout (Or in general, how to run specific commands
via java-client, I can't find it in the wiki.
"session.query("timeout[0]");" seems to not have any influence.
Query large files in general, for example query its number of instances, seems
to not be the problem.
Increasing the -Xmx in the basex-script did not help.
# Options for virtual machine (can be extended by global options)
BASEX_JVM="-Xmx10G $BASEX_JVM"
Increasing the -Xmx of the java-application did not help as well.
I hope you can help me.
best regards,
Jan
