    <p>I'm trying to load the JDBC driver to make some SQL calls to my AS400. I've tried running the connection on a computer which has JDBC installed on it and the URL and SQL calls work fine.</p> <p>I need to develop an app (currently for Android, though we're looking to expand to desktop application) which doesn't have the drivers installed. I am testing the code on an actual android device, not the emulator, so it has full internet permissions.</p> <p>jt400 has drivers located in com.ibm.as400.access.AS400JDBCDriver as <a href="http://publib.boulder.ibm.com/pubs/html/as400/v4r4/ic2924/info/java/rzahh/toolbox.htm" rel="nofollow">noted by IBM</a>.</p> <p>This is my code:</p> <pre class="lang-java prettyprint-override"><code> try { Class.forName("com.ibm.as400.access.AS400JDBCDriver").newInstance(); Connection conn = DriverManager.getConnection( url + schema + ";naming=sql;errors=full", uname, psswrd); // do SQL query stuff rs.close(); stmt.close(); conn.close(); } catch (ClassNotFoundException e) { this.basicOutput.setText("Class not found: " + e.getMessage()); System.out.println(e.getStackTrace()); } //catch (SQLException e) catch (Exception e) //need generic to catch all errors thrown { this.basicOutput.setText(e.getMessage()); System.out.println(e.getStackTrace()); } </code></pre> <p>I get a "Class not found: com.ibm.as400.access.AS400JDBCDriver" when I run this.</p> <p>I've done some research and it suggests that Class.forName isn't a good way to go. So I tried this as well:</p> <pre class="lang-java prettyprint-override"><code> DriverManager.registerDriver(new com.ibm.as400.access.AS400JDBCDriver()); </code></pre> <p>But this also yields the same error.</p> <p>The class is there. The compiled code doesn't throw any syntax errors, but for some reason, runtime can't find it.</p> <p>What am I missing?</p>

    1. COJDBC isn't something that is installed. A jdbc Driver is a class that interacts with your database. You need to have that class (usually within a .jar file) on your classpath when you run your application.

    2. COI see. Is there a way to include it or load it from a .jar that's included within the project instead of on the classpath?

    3. COYou include the `jar` in your project under the libs folder, then add that libs folder to the build path. Follow the steps here: http://stackoverflow.com/questions/1334802/how-can-i-use-external-jars-in-an-android-project

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.
