I have to create such a mechanism:

  1. Create in-memory (H2DB) database;
  2. Create tables and fill them using some data;
  3. Get stream to that database;
  4. Send that stream via WebDAV or something else;

I know everything except that “How to get stream to “in-memory” database created via H2DB”?

And some explanations:

  • I can’t create file because of some server restrictions;
  • I need that stream to create a file;

    You can create the SQL script from a database using org.h2.tools.Script.execute(String url, String user, String password, OutputStream out). This works even for in-memory databases.

    You can use the so called ‘in-memory file system‘. To get the file as a stream, you would need to use the internal H2 file API however (org.h2.IOUtils.openFileInputStream).
