I am trying to learn OSGi and i made one simple project where it will just create a table in a Sqlite DB. I added the "sqlite-jdbc-3.7.2.jar" in the build path. But when i run that project, it says "ClassNotFoundException".
I use Eclipse IDE with BndTools.
I searched other posts and some people said to add the jar as a different bundle and then export it. I tried it. In workspace i selected Import->Plugins and Fragments -> Select The Directory. But it doesnot list the Jar (Works for other Jars but doesnot detect sqlite-jdbc-3.7.2.jar).
I have done like below,
se.sample.sqlitedbconn.ConnActivator.java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
import org.osgi.framework.BundleActivator;
import org.osgi.framework.BundleContext;
import se.sample.connproperties.CreateTable;
import aQute.bnd.annotation.component.*;
@Component
public class ConnActivator implements BundleActivator {
Connection connection;
Statement statement;
@Activate
public void start(BundleContext context) throws Exception {
System.out.println("Starting");
try {
Class.forName("org.sqlite.JDBC");
connection = DriverManager.getConnection("jdbc:sqlite://home/raj/Desktop/EclipseProjectsWorkspace/ZWave.db");
} catch (Exception ex) {
System.err.println(ex.getClass().getName()+": "+ex.getMessage());
}
System.out.println("Connection To Database Successful");
CreateTable createTable = new CreateTable();
statement = connection.createStatement();
boolean isTableCreated = createTable.createANewTable(connection,statement);
if(isTableCreated){
System.out.println("Table Created Successfully!");
}else{
System.out.println("Table Creation Failed!");
}
statement.close();
}
@Deactivate
public void stop(BundleContext context) throws Exception {
System.out.println("Stopping");
if(connection != null){
connection.close();
}
System.out.println("Database Connection Closed!");
}
}
se.sample.connproperties.CreateTable.java
import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
public class CreateTable {
public boolean createANewTable(Connection connection, Statement statement) {
String sql = "CREATE TABLE Product " +
"(ProductId INT PRIMARY KEY NOT NULL,"+
"ProductName TEXT NOT NULL,"+
"ProductPrice REAL);";
try {
statement.executeUpdate(sql);
} catch (SQLException e) {
System.err.println(e.getClass().getName()+": "+e.getMessage());
return false;
}
return true;
}
}
When i Run this i get the following error:
Starting
Connection To Database Successful
java.lang.ClassNotFoundException: org.sqlite.JDBC not found by se.sample.sqlitedbconn [8]
! Failed to start bundle se.sample.sqlitedbconn-0.0.0.201503241305, exception activator error null from: se.sample.sqlitedbconn.ConnActivator:start#34
