<h1>Data Checks</h1>
<p>This section tells you about the checks that are implemented in
the wizard.</p>
<h3>Class definition</h3>
<p>The checks on this page are the same as the one in the ordinary
class wizard.</p>
<h3>Java Code Generation</h3>
<p>Since different values are needed for the different ways of code
generation let us splitt the checks up:</p>
<h4>Generating code with Java Emitter templates</h4>
<p><a href="pic/jetemplate_page2.png">Screenshot:</a> As seen in the
<a href="jetemplate.html">walkthrough</a> There are to ways for
generating code for a database table:<br>
Through an <a href="inputfile.html">input file</a>. Here the following fields are needed:</p>
<ul>
<li>Data Input must be a valid file.</li>
<li>Jet template may be provided as a valid file or a selection
from the drop down</li>
<li>DB product must be specified (NONE is not valid)</li>
</ul>
<p>Through a database connection:</p>
<ul>
<li>Jet template may be provided as a valid file or a selection
from the drop down</li>
<li>DB product must be specified (NONE is not valid)</li>
<li>Information from page 3 are needed</li>
</ul>
<p>If you choose to go with the option "Without DB" the following
fields are needed:</p>
