Body
This is my first post and I hoping I can reach out to the group. I'm pulling my hair out with this problem. I'm running a EC2 Ubuntu micro instance with LAMP. I'm using Java with JDBC to access the mysql database. The issue is that the Java code keeps throwing a "ClassNotFound" Exception when I execute: Class.forName("com.mysql.jdbc.Driver"); I have installed the following: <pre><code>sudo apt-get install mysql-server sudo apt-get install mysql-client sudo apt-get install libmysql-java </code></pre> My imports in the Java file are: <pre><code>import java.text.CharacterIterator; import java.text.StringCharacterIterator; import java.util.regex.*; import java.sql.*; import java.util.Properties; import java.net.*; import java.sql.Connection; import java.sql.DriverManager; </code></pre> My $CLASSPATH shows: <pre><code>.:/usr/share/java/mysql.jar:/usr/share/java/mysql-connector-java.jar:/usr/share/java/mysql.jar:/usr/share/java/mysql-connector-java.jar:/usr/share/java/mysql-5.1.10.jar:/usr/share/java/mysql-connector-java-5.1.10.jar </code></pre> In /usr/share/java I have: <pre><code>drwxr-xr-x 3 root root 4096 2012-05-25 02:01 . drwxr-xr-x 316 root root 12288 2012-05-24 21:21 .. -rwxrwxrwx 1 root root 448964 2009-11-23 22:38 gnome-java-bridge.jar -rwxrwxrwx 1 root root 2621 2010-03-05 04:16 libintl.jar lrwxrwxrwx 1 root root 31 2012-05-25 02:01 mysql-5.1.10.jar -> mysql-connector-java-5.1.10.jar -rwxrwxrwx 1 root root 754057 2010-01-26 08:02 mysql-connector-java-5.1.10.jar lrwxrwxrwx 1 root root 31 2012-05-25 02:01 mysql-connector-java.jar -> mysql-connector-java-5.1.10.jar lrwxrwxrwx 1 root root 16 2012-05-25 02:01 mysql.jar -> mysql-5.1.10.jar </code></pre> This is the code that always throws up the exception message to an output file: <pre><code>try { try { Class.forName("com.mysql.jdbc.Driver"); outyyy.write("Class loaded \n"); } catch (ClassNotFoundException e) { outyyy.write("Class not found! \n"); outyyy.write(e.getMessage() + " \n"); } this._connection = DriverManager.getConnection(url, this._user, this._pass); this._isConnected = true; } catch (Exception e) { this._isConnected = false; } </code></pre> I'm not sure if it's relevant but I can access and query the database just fine using PHP. Any assistance is much appreciated. Thanks, Andy

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.
