java - Creating a sqlite-file within appengine -

im struggeling gae filesystem restrictions. creating tool can export datastructur lot of different output-files (json, xml...) 1 of them sqlite-database-file. have ideas how can done in restricted environment?

i tried creating inmemory database without success:

 drivermanager.getconnection("jdbc:sqlite::memory:"); 

i tried use file-storage bucket:

drivermanager.getconnection("jdbc:sqlite:gs://"+bucketnameü+"/sqllite"); 

neither of them worked. i'm afraid not possible @ :( dont want start compute engine instance in order create sqllite file.

are there other frameworks out there possible create database file on fly.

here whole code:

connection c = null;             try {               class.forname("org.sqlite.jdbc");                          c = drivermanager.getconnection("jdbc:sqlite:gs://"+bucketnameü+"/sqllite");               statement statement = c.createstatement();               statement.setquerytimeout(30);  // set timeout 30 sec.               statement.executeupdate("create table person (id integer, name string)");               c.close();              } catch ( exception e ) {               system.err.println( e.getclass().getname() + ": " + e.getmessage() );               e.printstacktrace(system.out);             } 

i found interesting approach in google appengine: use sqlite file uploaded user

i tried sqljet inmemory database without success. gaevfs not idea either.

if still need access file system can create managed vms let avoid of app engine's limitations, particularly access file system.
