I have been using another Open Source Product for this: Pentaho BI Suite and have been very impressed.
It is an integration of multiple reporting tools:
Mondrian - Open Source OLAP Server
JFreeReport - Open Source Reporting
Kettle - Open Source Data Integration (E.T.T.L.)
Pentaho - Comprehensive Open Source BI Suite
Weka - Open Source Data Mining
The samples with the products include portlets. If I remember right, when I initially installed it, I simply modified the JNDI database connection definition and the SQL statements in the XML file and had portlets running with no coding.
I am using JBP 2.4.1.
I hope that helps.
Thanx for your reply.
It will be very helpful if anyone can specifically let me know the integration possiblities with Business Objects.
The environment already has as set-up running using Business Objects and the possibility of whether jboss portal can integrate it with needs to be explored.
I am not finding any docs regarding this.
