Hi @ll,

Re-sending from different address due to original message disappearing.

When running BaseX as a server and connecting to it my update statements are successful but when using BaseX from a jar inside the JVM – Database creation works fine – the update statements don't get committed – not visible to other clients or after restart – to the database.

Select queries work fine.

Code that – no exception – fails is:

final String xQueryUpdate = String.format("for $tab in doc('db')//tabs/tab[@id='%s'] return replace node $tab/content with %s", tabId, value); //$NON-NLS-1$

try {

synchronized (SESSION) {

new ClientQuery(xQueryUpdate, SESSION, SESSION.getOutputStream()).close();

// System.out.println(new XQuery(xQueryUpdate).execute(CONTEXT));

SESSION.notify();

}

} catch (final IOException ioex) {

ioex.printStackTrace();

}

When trying to use XQuery - In comment – I get:

org.basex.core.BaseXException: Improper use? Potential bug? Your feedback is welcome:

What might be the issue or have I misunderstood something?
