[JBoss Cache: Core Edition] - Re: Bad registration of class loader

by manik.surtani＠jboss.com

What version of JBoss Cache are you using? Could be that the FileCacheLoader in question does not make use of any region based class loaders. I'd recommend either the latest 2.1.X release or 1.4.X service pack if you need to be on 1.4.X. Alternatively, if your project jars are on your system classpath you won't see these errors, but that is not always a nice workaround. :) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154999#4154999 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4154999

by manik.surtani＠jboss.com

Basically read the user guide for 2.X. :-) There are examples, etc. up there as well. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4154998#4154998 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4154998

[JBoss Cache: Core Edition] - Re: How to use treecache.xml as configuration for jboss cach

by manik.surtani＠jboss.com

You could extend the Hibernate TreeCacheProvider to look up the cache from JMX instead of looking for the hardcoded treecache.xml file. Also, chk the Hibernate forums, IIRC someone did contribute a version of the TreeCacheProvider that did just that.

[JBoss Cache: Core Edition] - Re: Avoid evict on PUT and some general questions near the s

by manik.surtani＠jboss.com

I'm not sure I understand what it is you are looking for. Why would you want to replicate on PUT but invalidate on REMOVE/CHANGE? If you are retrieving state from a definitive source (such as a database) then any put, remove or change should result in an invalidation, unless you are putting something in the cache because you READ it from the database. In which case you would use a putForExternalRead().

[JBoss Portal] - Re: What exactly is the point of JBoss portal

by chris.laprun＠jboss.com

Thanks je.a.le for answering! Some more answers and precisions: 1) A portal server is NOT a servlet container. A servlet containers can work with any kind of web application. A portal is a combination of a portlet container and a user facing web application. Portlets are special web applications designed to run in a portal environment to which they delegate many responsibilities. It is therefore easier to create a portal-based application based on portlet components that are integrated into a unified interface. 2) If you are interested in portals, you should read the portlet specifications (Portlet 1.0 is JSR 168, Portlet 2.0 is JSR 286). They explain what a portlet is and how they interact with portals. 3) Any portal server provides the glue and services that allow your portlets to focus on their responsibilities. In particular, any portal server will take care of rendering your portlets on pages, user identification, security, etc. 4) There are many instances of sites running JBoss Portal. However, many of them are in an enterprise setting and not publicly available. You can see a live demo site running JBoss Portal at http://portal.demo.jboss.com/. Note also that jboss.org runs on JBoss Portal. :) 5) Yes. However, it is very often the case that people develop their own portlets so that they can suit their needs better. Contributing such portlets back to the community is always encouraged! ;) 6) Middle-sized website doesn't mean much. It's difficult to answer such a question abstractly as it will mostly depend on the portlets that are deployed. If you require more help, Red Hat offers training and consulting services.
