The wiki lists some more wrappers    Java wrapper  around a SWIG interface   http   tk-software home comcast net  A good tutorial to use JDBC driver for SQLite   it works at least    http   www ci uchicago edu wiki bin view VDS VDSDevelopment UsingSQLite Cross-platform JDBC driver which uses embedded native SQLite libraries on Windows  Linux  OS X  and falls back to pure Java implementation on other OSes  https   github com xerial sqlite-jdbc  formerly zentus  Another Java - SWIG wrapper  It only works on Win32  http   rodolfo 3 tripod com index html sqlite-java-shell  100  pure Java port of the sqlite3 commandline shell built with NestedVM   This is not a JDBC driver   SQLite JDBC Driver for Mysaifu JVM  SQLite JDBC Driver for Mysaifu JVM and SQLite JNI Library for Windows  x86  and Linux  i386 PowerPC

The example code leads to a memory leak in Tomcat  after undeploying the webapp  the classloader still remains in memory  which will cause an outofmemory eventually  The way to solve it is to use the sqlite-jdbc-3 7 8 jar  it s a snapshot  so it doesn t appear for maven yet

When you compile and run the code  you should set the classpath options value  Just like the following   javac -classpath   sqlitejdbc-v056 jar Text java  java -classpath   sqlitejdbc-v056 jar Text   Please pay attention to     and the sparate     win  the linux is

I understand you asked specifically about SQLite  but maybe HSQL database would be a better fit with Java  It is written in Java itself  runs in the JVM  supports in-memory tables etc  and all that features make it quite usable for prototyping and unit-testing

I found your question while searching for information with SQLite and Java  Just thought I d add my answer which I also posted on my blog   I have been coding in Java for a while now  I have also known about SQLite but never used it    Well I have used it through other applications but never in an app that I coded  So I needed it for a project this week and it s so simple use   I found a Java JDBC driver for SQLite  Just add the JAR file to your classpath and import java sql    His test app will create a database file  send some SQL commands to create a table  store some data in the table  and read it back and display on console  It will create the test db file in the root directory of the project   You can run this example with java -cp   sqlitejdbc-v056 jar Test   package com rungeek sqlite   import java sql Connection  import java sql DriverManager  import java sql PreparedStatement  import java sql ResultSet  import java sql Statement   public class Test       public static void main String   args  throws Exception           Class forName  org sqlite JDBC            Connection conn   DriverManager getConnection  jdbc sqlite test db            Statement stat   conn createStatement            stat executeUpdate  drop table if exists people             stat executeUpdate  create table people  name  occupation              PreparedStatement prep   conn prepareStatement               insert into people values                     prep setString 1   Gandhi            prep setString 2   politics            prep addBatch            prep setString 1   Turing            prep setString 2   computers            prep addBatch            prep setString 1   Wittgenstein            prep setString 2   smartypants            prep addBatch             conn setAutoCommit false           prep executeBatch            conn setAutoCommit true            ResultSet rs   stat executeQuery  select   from people             while  rs next                  System out println  name       rs getString  name                 System out println  job       rs getString  occupation                       rs close            conn close

There is a new project SQLJet that is a pure Java implementation of SQLite  It doesn t support all of the SQLite features yet  but may be a very good option for some of the Java projects that work with SQLite databases

David Crawshaw project sqlitejdbc-v056 jar  seems out of date and last update was Jun 20  2009   source here  I would recomend Xerials fork of Crawshaw sqlite wrapper   I replaced sqlitejdbc-v056 jar  with Xerials sqlite-jdbc-3 7 2 jar file without any problem    Uses same syntax as in Bernie s answer and is much faster and with latest sqlite library   What is different from Zentus s SQLite JDBC      The original Zentus s SQLite JDBC driver   http   www zentus com sqlitejdbc  itself is an excellent utility for   using SQLite databases from Java language  and our SQLiteJDBC library   also relies on its implementation  However  its pure-java version    which totally translates c c   codes of SQLite into Java  is   significantly slower compared to its native version  which uses SQLite   binaries compiled for each OS  win  mac  linux        To use the native version of sqlite-jdbc  user had to set a path to   the native codes  dll  jnilib  so files  which are JNDI C programs  by   using command-line arguments  e g   -Djava library path  path to the   dll  jnilib  etc    or -Dorg sqlite lib path  etc  This process was   error-prone and bothersome to tell every user to set these variables    Our SQLiteJDBC library completely does away these inconveniences       Another difference is that we are keeping this SQLiteJDBC libray   up-to-date to the newest version of SQLite engine  because we are one   of the hottest users of this library  For example  SQLite JDBC is a   core component of UTGB  University of Tokyo Genome Browser  Toolkit    which is our utility to create personalized genome browsers    EDIT   As usual when you update something  there will be problems in some obscure place in your code happened to me   Test test test
