 Then add a reference to a new jdbc resource in your web/META-INF/context.xml file. It defines a JNDI name, its class type, the driver class name that relates to the jar we just installed above, and a url to connect to the database. In my case I'm pointing to a directory (which must exist) on the file system.
 
-<Context>
-<Resource name="jdbc/sqlite"
-type="javax.sql.DataSource"
-driverClassName="org.sqlite.JDBC"
-url="jdbc:sqlite:/var/lib/tomcat7/dbs/test.db"
->
-</Resource>
-</Context>
+    <Context>
+        <Resource name="jdbc/sqlite"
+        type="javax.sql.DataSource"
+        driverClassName="org.sqlite.JDBC"
+        url="jdbc:sqlite:/var/lib/tomcat7/dbs/test.db"
+        />
+    </Context>
 
 In addition, you have to add the resource in your web.xml file. Note the name is the same the name above.
 
-...
-<resource-ref>
-<res-ref-name>jdbc/sqlite</res-ref-name>
-<res-type>javax.sql.DataSource</res-type>
-</resource-ref>
-...
+    ...
+    <resource-ref>
+        <res-ref-name>jdbc/sqlite</res-ref-name>
+        <res-type>javax.sql.DataSource</res-type>
+    </resource-ref>
+    ...
 
 Now you can make reference to the database in your Java code. This is  lifted from the sqlite example page:
 
-Connection conn = null;
-try {
-Context ctx = new InitialContext();
-DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/sqlite");
-conn = ds.getConnection();
-Statement statement = conn.createStatement();
-try {
-statement.executeUpdate("create table thing(x integer)");
-} catch (Exception e) { 
- // Could well be already there
-}
-statement.executeUpdate("insert into thing values(42)");
-ResultSet rs = statement.executeQuery("select * from thing");
-while (rs.next()) {
-writer.println("id = " + rs.getInt(1));
-
-} catch (Exception e) {
-writer.println(e.getMessage());
-} finally {
-try {
-if (conn != null) conn.close();
-} catch (SQLException e) {
-writer.println(e);
-}
-}

+        DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/sqlite");
+        conn = ds.getConnection();

+    ResultSet rs = statement.executeQuery("select * from thing");
+    while (rs.next()) {
