Javax.mail.*; not being seen by portal in EP 6

Question

Hello All,
It seems that when I deploy the following code:
package com.giggity;
import java.util.Properties;
import javax.mail.*;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import com.sapportals.portal.prt.component.AbstractPortalComponent;
import com.sapportals.portal.prt.component.IPortalComponentRequest;
import com.sapportals.portal.prt.component.IPortalComponentResponse;
public class Mailer extends AbstractPortalComponent
  public void doContent(IPortalComponentRequest request, IPortalComponentResponse response)
  Properties p = System.getProperties();
  p.put("mail.host", "stmail");
  try{
  MimeMessage message =
new MimeMessage(Session.getInstance(p, null));
message.setFrom(new InternetAddress("[email protected]"));               message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("[email protected]"));
message.setSubject("No work");
message.setText("Does not work");
Transport.send(message);
catch(Exception e)
I get a javax/mail/Address ClassNotFoundException.  In
the IDE (Eclipse with PDK plugin, not using NW04), it
compiles and builds just fine.  What is the problem?
Thanks.

Answer 1

Successful compilation or building in the eclipse/NWDS does not mean that it can be successfully deployed on the portal. If the Java build path has all the required jars, any project compiles and builts fine but that build path is not transported to the portal( see inside any par file, there won't be any .classpath and .project files. They are local only files).
========
   Add all your third party jar files to the component in this path( ..\dist\PORTAL-INF\lib). There is no need to add mail.jar as it's already available in sap j2ee engine. So add these lines to the portalapp.xml. (as told by jagdeep)
<application-config>
<property name="PrivateSharingReference" value="SAPJ2EE::library:mail"/>
</application-config>
