java.lang.NoClassDefFoundError: javax/jms/Connection

Anand called me today and informed me that Workflow Notification Mailer was refusing to start. The logs showed this error:

java.lang.NoClassDefFoundError: javax/jms/Connection

at oracle.apps.fnd.wf.bes.ConnectionManager$1.run(ConnectionManager.java:112)

at oracle.apps.fnd.wf.bes.Utilities$1.run(Utilities.java:558)

at java.lang.Thread.run(Thread.java:479)

We found Metalink Note 38266.1 which says that AF_CLASSPATH needs to have appsborg2.zip and not appsborg.zip. Anand checked this variable and found that appsborg.zip was present. He corrected this variable in the context file and added it in adovars.env. After this he restarted the services. Mailer came up without errors on restarting
