</p><div class="section"><a name="d0e11250"></a><div class="titlepage"><div><h3 class="title"><a name="d0e11250"></a>Introduction</h3></div></div><p>JBoss has a built-in implementation of the <a href="javascript:if(confirm('http://java.sun.com/products/javamail/1.2/docs/javadocs/index.html \n\nThis file was not retrieved by Teleport Pro, because it is addressed on a domain or path outside the boundaries set for its Starting Address. \n\nDo you want to open it from the server?'))window.location='http://java.sun.com/products/javamail/1.2/docs/javadocs/index.html'" tppabs="http://java.sun.com/products/javamail/1.2/docs/javadocs/index.html" target="_top">JavaMail API</a>. You can use this
service from inside and outside EJBs. We
describe here how to use the service. </p></div><div class="section"><a name="d0e11258"></a><div class="titlepage"><div><h3 class="title"><a name="d0e11258"></a>Installation & Configuration</h3></div></div><div class="orderedlist"><ol type="1"><li><p><a name="d0e11262"></a>Edit conf/<yourconfig>/jboss.jcml and find Mail
Service MBean (almost on the bottom).</p><p> a) Replace the User and Password attributes values with the user name and
password used to connect to your
mail server. You can find these values in your mail program. The mail
service will use this account to send mails,
so be sure that this mail account works properly (test it with your mail
program for example).</p><p> b) Replace the ConfigurationFile attribute value with the file containing
the mail settings. Default is
"mail.properties", which is also in the conf/<yourconfig>
directory. This file will be edited in step 2.</p><p> c) Replace the JNDIName attribute value with the JNDI name for your mail
session. The default is "Mail". This
JNDI name will be used in jboss.xml to identify the resource. This is
explained in more detail in step 4.</p></li><li><p><a name="d0e11271"></a>Edit the mail properties file you identified in step 1b. By
default, this is conf/<yourconfig>/mail.properties.</p><p> Edit the following lines:
<pre class="programlisting">
mail.user = sa005697 // the user to connect with; same as in step 1a
mail.pop3.host = pop3.wolmail.nl // the pop host to store the mail on
mail.smtp.host = smtp.wolmail.nl // the smtp host to send the mail to
mail.from = Memoirs@gamesphere.com // the 'from' field that is filled in by default in e-mails
</pre>
</p><p>
You can find most value in your mail program. You might want to inspect
the JavaMail specification for more
details.</p><p>
The last line, mail.debug, should be set to 'true' for now. This will
provide you with verbose debugging
information. Once you have everything running correctly, you can set it
to false.</p></li><li><p><a name="d0e11283"></a>Edit the ejb-jar.xml of the EJB that uses the mail service.
In your EJB, specify a <resource-ref> like this:
<pre class="programlisting">
<ejb-jar>
<description>JBoss JavaMail Sample Application</description>
<display-name>Mailer EJB</display-name>
<enterprise-beans>
<session>
<ejb-name>Mailer</ejb-name>
<home>org.jboss.docs.javamail.MailerHome</home>
<remote>org.jboss.docs.javamail.Mailer</remote>
<ejb-class>org.jboss.docs.javamail.MailerBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
</session>
</enterprise-beans>
<resource-ref>
<res-ref-name>mail/Mail</res-ref-name>
<res-type>javax.mail.Session</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</ejb-jar>
</pre>
</p><p> This will tell the EJB container that the EJB uses a javax.mail.Session
resource named mail/MyMail and that authorization is container managed.</p><p> You can change the name if you like, but be sure to use the same name in
step 6, in the code example. </p></li><li><p><a name="d0e11293"></a>Edit the jboss.xml of the EJB that uses the mail service.
If you don't have this file, create it and place it in the same directory as the ejb-jar.xml of the EJB. This file is JBoss specific and tells JBoss how to map the mail resource to the mail service provider in JBoss.
In this file, specify a <resource-manager> like this:
<pre class="programlisting">
<jboss>
<enterprise-beans>
<session>
<ejb-name>Mailer</ejb-name>
<jndi-name>Mailer</jndi-name>
</session>
</enterprise-beans>
<resource-managers>
<resource-manager>
<res-name>mail/Mail</res-name>
<res-jndi-name>Mail</res-jndi-name>
</resource-manager>
</resource-managers>
</jboss>
</pre>
</p><p> The name that you specify here is the name that you specified in step 3.
The JNDI name that you specify here is
the name that you specified in step 1c.</p></li><li><p><a name="d0e11301"></a>Code example
This code example assumes that you are working from inside a JBoss
container. For example, this is the case if
the code is placed in a JBoss managed SessionBean.</p><pre class="programlisting">
