I am not sure we have a API for this, but you could try to call dblook
from your app directily:
This worked for me:
public static void main(String[] args) throws SQLException {
Connection c =
DriverManager.getConnection("jdbc:derby:wombat;create=true");
Statement s = c.createStatement();
s.executeUpdate("create table t (i int)");
String args2[] = { "-d", "jdbc:derby:wombat"};
dblook.main(args2);
}
giving this on system out:
-- Timestamp: 2012-10-15 14:55:57.548
-- Source database is: wombat
-- Connection URL is: jdbc:derby:wombat
-- appendLogs: false
-- ----------------------------------------------
-- DDL Statements for tables
-- ----------------------------------------------
CREATE TABLE "APP"."T" ("I" INTEGER);
By proving an "-o" argument you could redirect this to a file and pick
it up from your app.
Hope this helps,
