Easy Infrastructure as a Service (IaaS) : Setting up Enterprise Private Cloud - Eucalyptus

Hi, today I need to suggest a Tejas Bavishi post:
During many phased of SDLC, there is a need to create hardware and software environments repeatedly to perform development, integration testing, system testing and user acceptance testing. This repeated deployment of hardware and software takes lot of time and eats into the bandwidth of today’s delivery organization to focus on the core responsibility of delivering tested application.Delivery organization also needs to provision and re-provision hardware and software for ever increasing requirements of development and testing in addition to the resources. Also, setting up of separate hardware and software takes time as well as prone to configuration errors. Plus, separate hardware installations consumes space which is at a premium.
Solution:The solution to above mentioned usage pain points is to setup private cloud. Eucalyptus...

Creating Cascade Parameters with Pentaho Report Designer 3.5.

Working on the jAPS/Pentaho integration I found  problems such as the use of cascading parametersI find very useful the following post by Prashant Raju. 
I followed his tutorial and the analysis of the file prtp this allow me to understand how  are structured the files:
  • datadefinition.xml, 
  • compound-ds.xml,
  •  sql-ds.xml
  • ...
This allow me to create dynamic forms inside a jAPS showlet(*) and execute  reports.
Thx again Prashant.

(*)A “Showlet” is a pluggable user interface component that displays contents, resources and usable services in a web page.
A showlet engine allows to manage these components in terms of configuration and position in a web page. More info

OpenBravo installation problem

In these days trying to install from source Openbravo found a lot of problems due to the fact that my version of ubuntu is 10.10 and therefore postgresql 8.3 was  no longer supported.
The error returned was due to the lack of library-postgresql contrib-8.3 no longer supported.
 Googling I found this link that allows  to do download the library and all its dependencies


Greetings and Happy New Year to all
