<p>When I start Tomcat (6.0.18) from Eclipse (3.4), I receive this message (first in the log):</p>

<blockquote>
  <p>WARNING:
  [SetPropertiesRule]{Server/Service/Engine/Host/Context}
  Setting property 'source' to
  'org.eclipse.jst.jee.server: (project name)'
  did not find a matching property.</p>
</blockquote>

<p>Seems this message does not have any severe impact, however, does anyone know how to get rid of it?</p>

From
Eclipse Newsgroup
:
The warning about the source property
  is new with Tomcat 6.0.16 and may be
  ignored. WTP adds a "source" attribute
  to identify which project in the
  workspace is associated with the
  context. The fact that the Context
  object in Tomcat has no corresponding
  source property doesn't cause any
  problems.
I realize that this doesn't answer how to get rid of the warning, but I hope it helps.
