Matt,
Glad to see that someone else would like to see this work. Our goals
may have been slightly different than yours. We were trying to use the
persistence layer and pojo's created with Hibernate in both an
internal Flex application and re-use it in a public Mach-II
application. Both our CF and Flex servers run as instances on top of
JRun. Hibernate works wonderfully with Flex and we are extremely happy
with it. CF was another story. We thought we had a workable solution.
However, while our solution worked with J2ee CF and JRun on a Mac OS
X machine, it did not work with the same version of CF and JRun on
Wiindows. We have found one of the major issues is that JRun doesn't
follow the standard servlet spec. There is definitely a classloader
issue with the JRun/CF combination. We have confirmed a basic bug with
the JRun/CF combination that prevents any java app using the log4j
logging classes from running within the CF instance. A basic class
that simply imports the logging classes and trys to do a log can
confirm it. We filed a bug report with Macromedia with code to
duplicate the problem but have not received a response.
We have a huge project and deadline looming and therefore had to
abandon our effort to use Hiernate with CF at the moment. I am
confident the same problems will not necessarily exist when using a
different J2ee app server such as JBoss or even just Tomcat. However,
our company is heavily invested in Macromedia technologies and we
would have a hard time getting management to approve a switch from
JRun to something else.
My co-worker and I will probably join your open-source effort to get
CF and Hibernate working. We may not be extremely active for a month
or so while we finish the project we are in the middle of. I have
included the steps that got it to work on the Mac OS X JRun/CF setup
below. Good luck!
-------------------------------------------
1. Put the following Hibernate files into
{application.home}/servers/cfusion/cfusion/WEB-INF/lib directory:
cglib-full-2.0.2.jar
commons-collections-2.1.1.jar
commons-logging-1.0.4.jar
dom4j-1.4.jar
ehcache-0.9.jar
hibernate2.jar
jta.jar
odmg-3.0.jar
DO NOT include the log4j.jar as it will conflict with what CF loaded.
2. Expand the {application.home}/lib/webservices.jar file. Remove the
"logging" folder from within the org/apache/commons directory.
Recreate the webservices.jar
ie: From within the webservices folder run the following command:
jar cvf ../webservices.jar *
3. Expand the
{application.home}/servers/cfusion/cfusion/WEB-INF/cfusion/lib/webservices.jar
file. Remove the "logging" folder from within the org/apache/commons
directory. Recreate this webservices.jar
ie: From within the webservices folder run the following command:
jar cvf ../webservices.jar *
