    <p>now I got some trouble connecting to my database. I know the tables i am looking for exist because when I access them with the command line they can be queried.</p> <p>Probably some minor oversight but I would love some help.</p> <p>This is where I make my connection to my database package persistence;</p> <pre><code>import java.sql.DriverManager; import java.sql.Connection; import java.sql.SQLException; public class DBRegistry { private static DBRegistry db = null; private static Connection connection = null; private DBRegistry() {}; public static synchronized DBRegistry getUniqueInstance() { if (db == null) { db = new DBRegistry(); return db; } else return db; } public synchronized Connection getDBConnection() { try { Class.forName("org.sqlite.JDBC"); connection = DriverManager.getConnection("jdbc:sqlite:src/database/taskMan.db"); return connection; } catch (SQLException e) {e.printStackTrace();} catch (ClassNotFoundException e) {e.printStackTrace();} return null; } public synchronized void closeConnection() { try { connection.close(); } catch (SQLException e) { e.printStackTrace(); } } } </code></pre> <p>Here is how I query it</p> <pre><code>public void create(UUID oid, Object obj) { Task t = (Task)obj; String statement = "INSERT INTO `complexTask` (`oid`,`description`,`status`) VALUES (?, ?, ?)"; try { PreparedStatement dbStatement = db.prepareStatement(statement); dbStatement.setString(1, oid.toString()); dbStatement.setString(2, t.getDescription()); dbStatement.setBoolean(3, t.getStatus()); dbStatement.executeUpdate(); } catch (SQLException e) { e.printStackTrace(); } } </code></pre> <p>and finally a stack trace:</p> <pre><code>java.sql.SQLException: no such table: complexTask at org.sqlite.DB.throwex(DB.java:288) at org.sqlite.NativeDB.prepare(Native Method) at org.sqlite.DB.prepare(DB.java:114) at org.sqlite.PrepStmt.&lt;init&gt;(PrepStmt.java:37) at org.sqlite.Conn.prepareStatement(Conn.java:231) at org.sqlite.Conn.prepareStatement(Conn.java:224) at org.sqlite.Conn.prepareStatement(Conn.java:213) at persistence.framework.ComplexTaskRDBMapper.create(ComplexTaskRDBMapper.java:23) at persistence.PersistanceFacade.create(PersistanceFacade.java:49) at persistence.persistanceStates.NewState.commit(NewState.java:10) at persistence.PersistentObject.commit(PersistentObject.java:23) at domain.objects.Task.commitToDB(Task.java:89) at domain.TaskRepository.commitToDB(TaskRepository.java:60) at domain.TaskController.persistanceCommit(TaskController.java:97) at presentation.TaskControlsJPanel$3.actionPerformed(TaskControlsJPanel.java:127) at javax.swing.AbstractButton.fireActionPerformed(AbstractButton.java:2012) at javax.swing.AbstractButton$Handler.actionPerformed(AbstractButton.java:2335) at javax.swing.DefaultButtonModel.fireActionPerformed(DefaultButtonModel.java:404) at javax.swing.DefaultButtonModel.setPressed(DefaultButtonModel.java:259) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(BasicButtonListener.java:253) at java.awt.Component.processMouseEvent(Component.java:6175) at javax.swing.JComponent.processMouseEvent(JComponent.java:3267) at java.awt.Component.processEvent(Component.java:5940) at java.awt.Container.processEvent(Container.java:2105) at java.awt.Component.dispatchEventImpl(Component.java:4536) at java.awt.Container.dispatchEventImpl(Container.java:2163) at java.awt.Component.dispatchEvent(Component.java:4362) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:4461) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:4125) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:4055) at java.awt.Container.dispatchEventImpl(Container.java:2149) at java.awt.Window.dispatchEventImpl(Window.java:2478) at java.awt.Component.dispatchEvent(Component.java:4362) at java.awt.EventQueue.dispatchEvent(EventQueue.java:604) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:275) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:200) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:190) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:185) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:177) at java.awt.EventDispatchThread.run(EventDispatchThread.java:138) </code></pre> <p>And some JUnit code for good measure, the first test passes and the second fails with a similar error to the one above</p> <pre><code>package test.persistence;

    1. COI'm wondering if the path to the database is not set correctly but then wondered if that would have made th first unit test fail.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
