workflow.20001.delta.repository

APAR status

• Closed as fixed if next.

Error description

• If you have not specified outgoing server parameters in the IBM
  WebSphere Application Server mail session configuration, you see
   the following error in the SystemErr.log file:
  
  SEVERE: Failed to initialize mail session. E-mail notification
  will be disabled. This can happen if you have not specified
  outgoing server parameters in the application server mail
  session configuration.
  java.lang.ClassCastException: javax.mail.Session incompatible
  with javax.mail.Session
  

Local fix

• 1. Add isolatedClassLoader="true" and
  <classpath>INSTALL_BAW_ROOT/BPM/Lombardi/lib/mail.jar</classpath
  > in "Built-in Mail Provider" of
  INSTALL_BAW_ROOT/profiles/DmgrProfile/config/cells/CellName/clus
  ters/AppClusterName/resources.xml. For example:
  <resources.mail:MailProvider xmi:id="builtin_mailprovider"
  name="Built-in Mail Provider" description="The built-in mail
  provider" isolatedClassLoader="true">
  <classpath>/opt/bpm/BPM/Lombardi/lib/mail.jar</classpath>
  <factories xmi:type="resources.mail:MailSession"
  xmi:id="MailSession_1586670919810" name="CNMailSession"
  jndiName="mail/CNMailSession" description="ICN Mail Session"
  mailTransportProtocol="builtin_smtp"
  mailStoreProtocol="builtin_imap"/>
  
  2. In the admin console, click System administration > Nodes,
  choose Managed nodes, and click "full resynchronize".
  
  3. Restart WebSphere Application Server.
  

Problem summary

• This issue occurs because javax.mail.Session class is loaded
  from two different .jar files.
