Yes the code I modified is indeed [1]
java/org/basex/examples/api/BaseXClient.java
<https://github.com/BaseXdb/basex/blob/master/basex-examples/src/main/java/org/basex/examples/api/BaseXClient.java>
The following line was needed to handle the first byte of the query result.
if (in.read() > 0)
I do like your "client.execute("xquery db:retrieve" suggestion better as it
does not require me to change the example client code.
However, what I really need is a way to do db:store and db:replace via
Xquery with an InputStream (e.g. without requiring the open/close commands).
