<a name="BEGIN" id="BEGIN"></a>
<ol>
<li>
<p>In the navigation tree, expand the Resources node.</p>
</li>
<li>
<p>Under the Resources node, select JavaMail Sessions.</p>
<p>The JavaMail Sessions page opens.</p>
</li>
<li>
<p>On the JavaMail Sessions page, click the name of the session that you are editing.</p>
<p>The Edit JavaMail Session page opens.</p>
</li>
<li>
<p>In the Mail Host field, specify the host name of the default mail server.</p>
<p>The connect methods of the Store and Transport objects use this value if a protocol-specific host property is not supplied. The name must be resolvable to an actual host name.</p>
</li>
<li>
<p>In the Default User field, type another user name to provide when connecting to a mail server.</p>
<p>The connect methods of the Store and Transport objects use this value if a protocol-specific username property is not supplied. The user name must contain only alphanumeric, underscore, dash, or dot characters.</p>
</li>
<li>
<p>In the Default Sender Address field, type the e-mail address of the default user.</p>
<p>The format is <i>username</i><code>@</code><i>host</i>.<i>domain</i>.</p>
</li>
<li>
<p>In the Deployment Order field, type a number to specify the deployment order of the JavaMail session resource.</p>
<p>Resources with a lower number are loaded first at server startup. The default value is 100.</p>
</li>
<li>
<p>In the Description field, change the description for the mail session.</p>
</li>
<li>
<p>Select the Status Enabled checkbox to enable the mail session.</p>
<p>The default value is Enabled.</p>
</li>
<li>
<p>In the Store Protocol field, define the Store object communication method to be used.</p>
<p>By default, the Store Protocol is <code>imap</code>.</p>
</li>
<li>
<p>In the Store Protocol Class field, specify the Store communication method class that implements the desired Store protocol.</p>
<p>By default, the Store Protocol Class is <code>com.sun.mail.imap.IMAPStore</code>.</p>
</li>
<li>
<p>In the Transport Protocol field, specify the transport communication method.</p>
<p>By default, the Transport Protocol is <code>smtp</code>.</p>
</li>
<li>
<p>In the Transport Protocol Class field, specify the communication method for the Transport class.</p>
<p>By default, the Transport Protocol Class is <code>com.sun.mail.smtp.SMTPTransport</code>.</p>
</li>
<li>
<p>Select the Debug checkbox to enable extra debugging output, including a protocol trace, for this mail session.</p>
<p>If the JavaMail log level is set to <code>FINE</code> or finer, the debugging output is generated and is included in the system log file. See <a href="../../../common/en/help/task-eelogginglevels.html">To Configure Log Levels</a> for information about setting the log level.</p>
</li>
<li>
<p>In the Additional Properties table, specify additional properties required by applications, such as a protocol-specific host or username property.</p>
<p>For a list of the available properties, see JavaMail API documentation (<code><a href="http://java.sun.com/products/javamail/javadocs/index.html">http://java.sun.com/products/javamail/javadocs/index.html</a></code>). Additional properties must begin with <code>mail-</code> and must use hyphens, not periods, as separators. For example, <code>mail-debug</code> is correct, but <code>mail.debug</code> is not. The GlassFish Server back end converts the hyphens into the periods expected by the JavaMail API.</p>
<ul>
<li>
<p>To add a property, click the Add Property button. In the blank row that appears, type the property name in the Name field, and type the property value in the Value field.</p>
</li>
