This is a simple series of steps to get something going with SQLite and Processing. It is based on the library available from bezier.de/processing/libs/sql/#download, which is available here for redundancy.

Download

• Go to http://bezier.de/processing/libs/sql/#download and download the SQLibrary-0.1.0.zip

New PDE sketch

• Unzip the SQLibrary and copy the examples/SQLite_example1 folder into a new location. This will become the sketch you'll be using to test SQLite and Processing.

• Your new sketch, called SQLite_example1 should contain a file and a folder
  • SQLite_example1.pde
  • data

• the data folder should contain an SQLite database called test.db

New Java Classes

• Locate the SQL.java and SQLite.java programs in the source, de, bezier, data, sql folders, and copy them to the new SQLite_example1 folder.
• This folder should now contain
  • code
  • data
  • SQL.java
  • SQLite_example1.pde
  • SQLite.java

(folders appear in italics)

• Edit the two java programs and remove the package line.
• Futhermore, change the declaration of the class in SQLite.java to read

    public class SQLite extends SQL

• The two modified files are available here.

New Library

• copy the file sqlitejdbc-v053-pure.jar from the library folder of the unzipped archive you downloaded, and copy it into the code folder in your sketch folder.

Testing

• That's it!
• Try and run the sketch and verify that you get an output:
