SQLite JDBC driver developed by [wiki:leo] is an extension of Zentus's SQLite JDBC driver that enables Java to access SQLite database files.
Our SQLiteJDBC library, developed as a part of Xerial project, requires no configuration since all native libraries for Windows, Mac OS X, Linux and pure-java SQLite, which works in any OS environment, are assembled into a single JAR (Java Archive) file. The usage is quite simple; [#Download] our sqlite-jdbc library, then append the library (JAR file) to your class path. See [#Usage].
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, dylib, so files, which are JNDI C programs) by using command-line arguments, e.g., -Djava.library.path=(path to the dll, dylib, 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 library 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.

Download the latest version of SQLiteJDBC from here.
* version 3.6.x is the latest one. * Do not use sqlite-jdbc-v0xx.jar, which are obsolete libraries but left here for users still using these versions.
If your are an Maven user, follow the instruction described [#UsingSQLiteJDBCwithMaven2].
The early releases (beta) of sqlite-jdbc with some advanced features are available from here:
* http://www.xerial.org/maven/repository/snapshot/org/xerial/sqlite-jdbc
Since sqlite-jdbc-3.6.19, the natively compiled SQLite engines will be used for the following operating systems:
* Windows XP, Vista (Windows, x86 architecture, x86_64) * Mac OS X 10.4 (Tiger), 10.5(Leopard), 10.6 SnowLeopard (for i386, x86_64, Intel CPU machines) * Linux i386 (Intel), amd64 (64-bit X86 Intel processor)
In the other OSs not listed above, the pure-java SQLite is used.
If you want to use the native library for your OS, [#BuildfromSource].
1. Download sqlite-jdbc-(VERSION).jar from [http://www.xerial.org/maven/repository/artifact/org/xerial/sqlite-jdbc/], then append this jar file into your classpath. 1. load the JDBC driver org.sqlite.JDBC from your code. (see the example below)
* Usage Example (Assuming sqlite-jdbc-(VERSION).jar is placed in the current directory)
* Sample.java
The usage of SQLite-JDBC driver is the same with the original version. See http://www.zentus.com/sqlitejdbc/ for the general usage. For usage of JDBC, see my article about JDBC.
Here is an example to select a file C:\work\mydatabase.db (in Windows)
A UNIX (Linux, Mac OS X, etc) file /home/leo/work/mydatabase.db
SQLite supports on-memory database management, which does not create any database files. To use a memory database in your Java code, get the database connection as follows:
In some OS (e.g., old Linux kernel), loading native library causes JVM crashes. In this case, set sqlite.purejava=true JVM variable:
Or, set this System property before loading the JDBC driver:
In this mode, sqlite-jdbc never uses native SQLite libraries.
* Take a backup of the whole database to "backup.db" file:
* Restore the database from a backup file:
Another sample code is here.
Our SQLite JDBC driver package (i.e., sqlite-jdbc-(VERSION).jar) contains three types of native SQLite libraries (sqlite-jdbc.dll, sqlite-jdbc.dylib, sqlite-jdbc.so), each of them is compiled for Windows, Mac OS and Linux. An appropriate native library file is automatically extracted into your OS's temporary folder, when your program loads "org.sqlite.JDBC" driver.

If you are familiar with Maven2, add the following XML fragments into your pom.xml file. With those settings, your Maven will automatically download our SQLiteJDBC library into your local Maven repository, since our sqlite-jdbc libraries are synchronized with the Maven's central repository.
Do not include sqlite-jdbc-(version).jar in WEB-INF/lib folder of your web application package, since multiple web applications hosted by the same Tomcat server cannot load the sqlite-jdbc native library more than once. That is the specification of JNI (Java Native Interface). You will observe UnsatisfiedLinkError exception with the message "no SQLite library found".
Work-around of this problem is to put sqlite-jdbc-(version).jar file into (TOMCAT_HOME)/lib directory, in which multiple web applications can share the same native library file (.dll, .dylib, .so) extracted from this sqlite-jdbc jar file.
If you are using Maven for your web application, set the dependency scope as 'provided', and manually put the SQLite JDBC jar file into (TOMCAT_HOME)/lib folder.
If your OS is not supported, consider to build the [#SourceCodes] from scratch.
* Install Java SDK (1.5 or higher) http://java.sun.com
* Install [http://mercurial.selenic.com/ Mercurial] (hg)
* Install Maven2 (2.0.7 or higher) http://maven.apache.org
* You need to set PATH variable so as to run mvn command. Here is an example setting for maven:
* Clone the Mercurial repository
* (If necessary) set the JAVA_HOME environment variable as your JDK folder (e.g. /usr/java/jdk1.5.0_13), and PATH so that you can run the javac command.
* Type make in the sqlite-jdbc folder:
* A new SQLite JDBC jar file that additionally supports your OS will be generated as target/sqlite-jdbc-(version).jar
* Windows XP (32-bit) * dependency check
* Mac OS X (10.4.10 Tiger ~ 10.5 Leopard) * dependency check
* Linux (glibc-2.5.12) * Dependency check
