Railo on Lifeary
Andrea Campolonghi
I have a Liferay install on Tomcat. I am testing the option to
install Railo on the same Tomcat install and start using cfm in place
of jsp for managing the portlets output.
Basically the plan is to produce liferay portlets but ..... skip
jsp ......
So I have added a railo folder ( with all railo jar ) to the tomcat
classpath.
Anything loads but I think I have a conflict in an xml parser jar:
Liferay restart and I can see install homepage.
When I try to open railo-context I get this:
javax.servlet.ServletException:

cast to org.apache.xerces.xni.parser.XMLParserConfiguration

Delete these jars from the railo lib folder:
* apache-xml-xerces.jar
* xml-apis.jar
* ss_css2.jar
* tagsoup.jar
* serializer.jar
* w3c-dom.jar
And theoretically you should be good to go. There might be one
other-- I guess I should have left my old "not so 'leet" blog post
un-edited and linked to a new one instead. Eh. You live, you learn.
:)
Force be with you, esse!

You might want to try this all over again with a new Liferay instance
and place the railo war file in ../liferay_install_dir/deploy/ then
start up liferay. You should be able to go to the Railo admin page
once liferay starts up, however you still need some other extra steps
before you can start writing CF portlets. I haven't had success
creating portlets with Railo using CFML and a free open source code
that Adam wrote to make any CF container utilize a portal engine, I
tried this for Adobe's CF and can build portlets.
Adam,
Thanks for your work on this, I tried using cfportlets version 1 that
you have up on http://wiki.cfinnovate.com/display/cfmlportlets/Home,
Liferay was able to see the portlet I created and loaded it on startup
but keeps coming up blank when I try to place the portlet into a
portal page. Just checked the site and it seems it's down, are you
still working actively on this or has it been abandoned?

Hi Andrea,
You might want to try this all over again with a new Liferay instance
and place the railo war file in ../liferay_install_dir/deploy/ then
start up liferay. Yo u should be able to go to the Railo admin page
seyi
Thanks Adam, would appreciate it. I'm trying Liferay bundled with
Tomcat. Also from what I can tell it seems cfmlportlets would only
work using .cfm files and not cfcs. Would I be right in that
assumption?

the problem is a version conflict with different versions of the jar apache-xml-xerces.jar i think.

Some question:1) Implementing a portlet via cfml will I still be able to access to the liferay context ??
Yep, everything is exposed through the portlet bridge, if it is not let me know and it can easily be done.
2) What are for you the pro and cons of the approaches
On the pro side all your development is in a familiar technology and you can leverage your entire backend pretty easily (assuming it is CFML based already). Also the cfmlportlets bridge allows for the full lifecycle of a CFML application, including application & session lifecycle. One additional pro is Railo/the bridge handle all the crap of the application not truly running in the HTTPServletRequest paradigm most of us are familiar with so you have less of a learning curve. On the con side, its one more layer of indirection between the portal and your code, so debugging can get hairier (though I have yet to see a situation where this impedes development the possibility is there).
3) Do you have a sample of a cfml portlet ?
Website is back up http://cfmlportlet.cfinnovate.com Pretty easy, all you do is made a view.cfm and configure and hello world is done. You can of course get much more complicated than that if you choose.
4) How do you involke Railo if is not globally available ?
You could still make Railo globally available, I think. The protlet bridge does make use of a selfinstalled customtag which might need to be corrected for Railo (not sure) but everything else should work. Typically I just run my CF engine in the war as part of my portlet deployment. In this case you just configure your portlet as described on the wiki and it works :)
