javamail question

[keegank]

I am trying to use the sendMail example that comes with tomcat here

http://82.35.100.85:8080/examples/jsp/mail/sendmail.jsp

When I submit I get the following error

I have the activation.jar and mail.jar in the common/lib directory and have the followin added to the classpath

C:\tomcat\Tomcat 4.1\common\lib\activation.jar; C:\tomcat\Tomcat 4.1\common\lib\mail.jar

Does anyone have an idea what the error actually means and what I need to do to fix it.

Thanks

Andy

Do the flowing steps to configure mail for tomcat:


1. paste the following line at the bottom, or below similar entry in <installdir>\conf\catalina.policy file: and modify the smtp server with your own.


// Permission to send email via SMTP - (permission to connect to mail server).
permission java.net.SocketPermission &quot;smtp.host:25&quot;, &quot;connect,resolve&quot; ;

2. modify your <installdir>\conf\server.xml as shown blow with your relevant info...(change only &quot;value&quot; and not the parameters.

<Resource name=&quot;mail/Session&quot; auth=&quot;Container&quot;
type=&quot;javax.mail.Session&quot;/>
<ResourceParams name=&quot;mail/Session&quot;>
<parameter>
<name>mail.smtp.host</name>
<value>smtp-server.host</value>
</parameter>
<parameter><name>mail.smtp.user</name>
<value>username</value>
</parameter>
<parameter><name>mail.from</name>
<value>username@host.com</value>
</parameter>

3. enter the <value>smtp.host</value> line. Change the value to the name of your SMTP mailhost.

4.enter the <value>userid</value> line. Change the value to the userid you use for sending and receiving mail.

5.enter the <value>username@mail.host</value> line. Change the value to the return e-mail address (the 'From' field)

You should now be all set to go.

There is nothing to do here with Tomcat policy since the exception is a NoClassDefFoundError.

The JVM will throw an AccessControlException or a SecurityException when the SecurityManager detects a security policy violation.

If CLASSPATH is set up correctly then the only problem would be: there is no read access for the class.

Actually I had the same problem.

jaf-1_0_2.zip contains:
-rw------- activation.jar

If the user doesn't own the file he won't have rigths to access it.

solution:
-rw-r--r--
