Hello Eitan,

I see multiple issues with your code:

- First of all, you are using the Client/Server architecture, which does not seem to be very useful (at least to me, maybe you have a particular use case) if you want to use WRITEBACK. I am not even sure if WRITEBACK is actually used on server side. You might want to take a look at the local examples provided here https://docs.basex.org/wiki/Java_Examples to see how you can use BaseX locally. - You are executing the command to set WRITEBACK to true _after_ you run the query, i.e. during runtime of the query WRITEBACK is still the default (which is false) - Issue #848 could still apply, as it is unclear for me if you are using a database document or one read from the file system. If you add the file using CreateDB it is added to the database and as stated in the issue it is currently not possible to write back these files. You have to explicitly read the file from disk.

Cheers, Dirk

Hi

I change the query to

String query = "for $item in doc('src/xmlFile/input.xml')//package return insert node <e123/> into $item";

with doc and is still not working.

Thanks

Maybe it's due to...

Eitan,

if you want help, please spend more time in creating examples that work out of the box (see [1] for more details), and write to the basex-talk mailing list. What do you expect your qeery to do? What is the error?
