Error opening connection SQLite on Raspberry pi

Question

Update: I just check the latest JDBC jar which I use, and it's missing the map /Linux/arm/libsqlitejdbc.so, Would this problem be fixed by downloading this file from somewhere? Can't find it anywhere.

Edit: Problem seems to be this, however I don't know how to fix this.

Caused by: java.lang.Exception: Error loading native library: /org/sqlite/native/Linux/arm/libsqlitejdbc.so

I'm trying to use a SQLite database on my raspberry pi. However I can't get it to work. I get the output posted below. I'm using the JDBC driver. The code works fine on my main computer. I have searched everywhere but can't find a solution. I packed my code into a Jar file if that matters.

Relevant code:

     private final String dbLocation = "jdbc:sqlite:" + System.getProperty("user.home") + "/ServerSQLite.db";

    public SQLServer() throws ClassNotFoundException {
        System.out.println("DB location: " + dbLocation);
        Connection connection = null;
        Class.forName("org.sqlite.JDBC");
        try {

            // create a database connection
            connection = DriverManager.getConnection(dbLocation);

Output:

DB location: jdbc:sqlite:/usr/share/tomcat7/ServerSQLite.db
Error opening connection

Edit: same problem with hardcoded location which should have both read and write permission:

jdbc:sqlite:/home/pi/ServerSQLite.db
Error opening connection

Thankful for any help I can get :)

Edit 2: Thought I printed stack trace, but didn't here it is:

java.sql.SQLException: Error opening connection
    ...Lots of exception

Problem seems to be Caused by:

java.lang.Exception: Error loading native library: /org/sqlite/native/Linux/arm/libsqlitejdbc.so

Answer 1

You need to download an arm build of SQLite library. I found only one place where you can get it: https://bitbucket.org/xerial/sqlite-jdbc/issue/79/compile-for-arm

Answer 2

For some reason, it looks like the Pi's $HOME is set to a read-only system location. This is buggy, but the best workaround is to permit the user to specify a property that will override the entire file name instead of always using the home directory.

Answer 3

I use this in my POM and works fine for me

<dependency>
        <groupId>org.xerial</groupId>
        <artifactId>sqlite-jdbc</artifactId>
        <version>3.8.10.1</version>
</dependency>

If you only need the jar
