Hi Jacek, guys, Basically, CloudFoundry tries to be as generic as possible, when it comes to integrating runtimes and frameworks. Adopters are heavily contributing integration with different platforms and languages, so I thought about OpenEJB in this context. Currently, you can use only Tomcat as a Java framework (a contribution of Virgo integration is on the way). I suppose that maybe at some moment of time, running a classical JavaSE application on CF should be introduced as well, since the CF platform looks quite flexible and extensible.
So, for the moment, a possible OpenEJB integration point, would be to provision the OpenEJB+Tomcat integration on CF. I think that this won't be difficult at all, but I haven't played with it yet. I suppose the from OpenEJB side nothing has to be particularly done about it. Currently Tomcat is provisioned on CF by unzipping its archive, and running shell scripts for starting/stopping the Catalina. There is a recognition step as well, which is pretty simple and aims to determine the app type by taking a look at the file system structure of the application. An 'OpenEJB' application could be defined by searching for \META-INF\ejb-jar.xml, for instance. At the staging step, a fresh new Tomcat instance could be provisioned, and the OpenEJB framework injected as well (according to the OpenEJB+Tomcat integration details, that I am not familiar with). When running simple JavaSE apps is supported by CF, no Tomcat should be needed. TomEE could be brought up in the cloud as well. I cannot myself evaluate whether this would be worth doing, and whether people will be happy to use it, but it would definitely be the first clouded EJB and clouded Java EE 6 web profile offering (speaking of open source, of course). And this sounds awesome to me :) Kindest Regards, Krum. -----Original Message----- From: Jacek Laskowski [mailto:[email protected]] Sent: Friday, July 29, 2011 10:02 AM To: [email protected] Subject: Re: Investigation integration points with Cloud Foundry (.org) ?

Hi Krum, I'm only sligtly aware of CF's existence and haven't tried it out yet. What would it take to provision openejb modules from it? Should we take any special steps to make it happen?
