[jira] [Comment Edited] (KARAF-3067) NoClassDefFoundError on
startup when log4j SMTPAppender is configured
[ https://issues.apache.org/jira/browse/KARAF-3067?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14043437#comment-14043437 ]

------------------------------------------------------------------
Problem with custom distributions can be solved by creating a custom feature package containing the javax.mail API and adding feature to startupFeatures of distribution (which infact will add bundle to etc/startup.properties). Example:
{code:title=features.xml of feature repository}
(...)
<feature name="javax.mail" version="1.4.4">
<bundle start-level="7">mvn:javax.mail/mail/1.4.4</bundle>
</feature>
(...)
{code}
{code:title=pom.xml of custom distribution}
<startupFeatures>
<feature>javax.mail</feature>
</startupFeatures>
{code}
In my opinion javax.mail API should be installed by default in Karaf to support SMTPAppender in logging. But maybe this is rather an improvment than a bug.
Edit: Sorry Achim, I saw your comment too late. :-)
