~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Summary:
ColdFusion 6.1 Updater 1 in the ColdFusion MX for JRun4
configuration only creates a /WEB-INF/cfclasses directory
under the web server root and places compiled java .class
files created from .cfms and .cfcs. The .class files can
be downloaded by end users.
NOTE: ColdFusion 7.0 is not affected.

~~~~~~~
Solution:
Macromedia has released a workaround addressing the problem.
This issue will be fixed in the next updater.
~~~~~~~
Affected Software Versions:
J2EE Configuration - ColdFusion MX 6.1 for JRun4 (Updater 1)
~~~~~~~
Severity Rating:
Macromedia categorizes this issue as a critical update and
recommends users immediately patch their installations.
~~~~~~~
Details:
The ColdFusion MX 6.1 Updater renames the
/jrun4/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/
cfclasses directory to cfclasses-backup but does not recreate
the ..../cfusion-war/WEB-INF/cfclasses directory.
After restarting the ColdFusion server, subsequent requests
compile .cfms and place the .class files incorrectly under
the web server root in a newly created /WEB-INF/cfclasses
directory, rather than under the application root
/jrun4/.../cfusion-war/WEB-INF/cfclasses.
~~~~~~~
Making the Changes:
NOTE: Back up your existing files before making changes.
As always, test the changes in a non-production environment
before applying the changes to production servers.
J2EE Configuration - ColdFusion MX 6.1 for JRun4
1. Stop all ColdFusion MX 6.1 servers.
2. Install the ColdFusion MX 6.1 Updater.
If the ColdFusion MX 6.1 updater has previously been applied,
delete the existing /WEB-INF/ directory under the web server
root. For Microsoft IIS, the default is /inetpub/wwwroot/,
for Apache, /apache/htdocs/, and for IPlanet/SunOne /
{iPlanet / SunOne}/servers/docs/.
3. Create the {jrun_root}/servers/cfusion/cfusion-ear/
cfusion-war/WEB-INF/cfclasses directory.
4. Start ColdFusion MX 6.1 servers.
Observe when .cfms are invoked, the .class files are placed
in {jrun_root}/servers/cfusion/cfusion-ear/cfusion-war/
WEB-INF/cfclasses directory.
