Hi,

I am working on a new project built on websphere portal.  
I need to be able to have about 2 million concurrent users.  
If I use JRuby, will it work?  
Can JRuby work well on websphere portal?  
Can JRuby work with porltets?

Please help…

Best of luck with hijacking entire internet 😉

And you’re likely to get a better answer in jruby mailing list.

Yes, it will work. But there have not been many examples of JRuby on  
Rails sites with 2M concurrent users. It will be interesting to see.

I have not done it myself, but there are others running on WebSphere.  
In general, any web app container should work about the same.

I’m not familiar enough with the portlet spec to know for sure, but it  
should work at least as well as a typical Java web application, no?

All good questions for the JRuby mailing list.

Now there is JRuby support for portlet development in Liferay Portal.  
There is an example code, although I haven’t found any documentation  
on that. But I don’t think you can use Ruby on Rails to develop  
portlets. Just plain ruby.

Charlie,

Just wanted to say hello and that I enjoyed your keynote at the Lone  
Star Ruby conference.

We’re converting a PHP project to run on Rails and will use JRuby for a  
variety of reasons.

Thank you for your hard work.
