B4J Question sqlite wal mode on Mac OS X

[xulihang]

Hi,

My app uses keyvaluestore and I have enabled the wal mode for faster loading speed and multithread reading by add the code below in keyvaluestore's initialize sub:

sql1.ExecNonQuery("PRAGMA journal_mode = wal")

It works well in windows, but crashed in OS X. I got this error:

java.sql.SQLException: [SQLITE_NOTADB]  File opened that is not a database file (file is encrypted or is not a database)

Database created by OS X works fine. But sqlite is not in wal mode.

I have attached the database created under windows.

I solved it. It is the upstream sqlite-jrdc's problem. I downloaded the latest jar from here:download, and it works on Mac.

Hi, I have the same problem, with windows and tuttook, instead with mac nothing gives me the same error in post # 1, I had already changed qlite-jdbc-3.30.1.jarmailrultatonon does not change. how can i make the sqlite db work also with the mac?
What else do you have some application that makes a package for the mac, without starting with run.command?
thank you
