org.sqlite.JDBC will not be found

Hello,

I'm just trying to generate a connection to a SQLITE database. Here you will see the code:

private void getConnection() throws ClassNotFoundException, SQLException {
Class.forName("org.sqlite.JDBC");
con = DriverManager.getConnection("jdbc:sqlite:SQLiteTest1.db");
initialise();
}

When I run the application in InteliJ IDEA 2016.2.2 I will get always the ClassNotFoundException

java.lang.ClassNotFoundException: org.sqlite.JDBC

I understand org.sqlite.JDBC will not be found, because it seems not to appear in the classpath of the project.
But I have insert sqlite-jdbc-3.8.11.2.jar over CTRL+ALT+SHIFT+S "Libraries":

.idea/libraries/sqlite_jdbc_3_8_11_2.xml:
<component name="libraryTable">
<library name="sqlite-jdbc-3.8.11.2">
<CLASSES>
<root url="jar://$APPLICATION_HOME_DIR$/lib/sqlite-jdbc-3.8.11.2.jar!/" />
</CLASSES>
<JAVADOC />
<SOURCES>
<root url="jar://$APPLICATION_HOME_DIR$/lib/sqlite-jdbc-3.8.11.2.jar!/" />
</SOURCES>
</library>
</component>
In the left pane of the Editor where the tree of packages in my project are shown, I can see under "Libraries" the directory "org". In "org" I found "sqlite" and the Class JDBC. It is also installed.
But why "org.sqlite.JDBC" will not be found?
Can someone help me?

Thanks

Andreas
