<p>Hi Below is my code which will use as Connection Factory class. But i am getting java.lang.ExceptionInInitializerError. Please advice how to fix? I assume this is the trap because of static block, but not aware what exactly is this.</p> <pre><code>package j2ee.dao; import java.sql.Connection; import java.sql.DriverManager; import java.util.Properties; public class ConnFactory { public static Properties prop; static { prop=new Properties(); try { prop.load(ConnFactory.class.getClassLoader().getResourceAsStream("DBConfig.properties")); } catch (Exception e) { e.printStackTrace(); } } private static ConnFactory instance = new ConnFactory(); public static final String URL = prop.getProperty("DEVURL"); public static final String USER = prop.getProperty("DEVUSER"); public static final String PASSWORD = prop.getProperty("DEVPASSWORD"); public static final String DRIVER_CLASS = prop.getProperty("DEVDRIVER_CLASS"); private ConnFactory() { try { Class.forName(DRIVER_CLASS); } catch (ClassNotFoundException e) { e.printStackTrace(); } } private Connection createConnection() { Connection connection = null; try { connection = DriverManager.getConnection(URL, USER, PASSWORD); } catch (Exception e) { System.out.println("ERROR: Unable to Connect to Database."); } return connection; } public static Connection getConnection() { return instance.createConnection(); } public static void main(String a[]) { Connection test=ConnFactory.getConnection(); System.out.println("Done"); } } </code></pre> <p>Error is :</p> <pre><code>Caused by: java.lang.NullPointerException at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:188) at j2ee.dao.ConnFactory.<init>(ConnFactory.java:28) at j2ee.dao.ConnFactory.<clinit>(ConnFactory.java:20) </code></pre>

Guidance

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.
