Let’s however cut the negativity and enjoy the fun of creating a download utility using PLSQL

Coding different page layouts in a single rtf template and the importance of Contexts in BI Publisher

The requirement was to generate an output in statement page size or in legal page size, depending on a parameter value. Since the parameter was passed from Siebel and since I did not know the method to conditionally call different rtf files from Siebel so I had to code everything in 1 single rtf file

Using custom transformations in BI Publisher 10G

Out of all my posts on BI publisher, this one is my personal favorite. The article describes a mechanism to use any custom function in BI publisher reports. This opens a whole box of opportunities. The custom functions have to be written in java which means that you can code anything between the sun and the earth and then use it in your BI Publisher reports.

Silenced writeback using webservices - part 2

Happy Valentine's day to all :)

This is the 2nd part of the series in which I am using webservies to writeback. In my previous article, I showed a mechanism to do writeback using a utility of OC4J. That mechanism works well with OC4J and OAS (Oracle Application Server) but for other webservers we need an independent webservice. In this article, I'm creating an independent webservice and deploying it on weblogic

Silenced writeback using webservices - part 1

This article presents an alternate way to do write back in OBIEE. I call it silenced because this doecs not involve the creation of text boxes to writeback something into the database. The mechanism is helpful if we intend to writeback some info, depending on some action taken by the user and we do not want the user to explicitly write the info in text boxes

Freedom to format in OBIEE

I’m finally back to my blogging business J. This article deals with the usual OBIEE business of formatting. OBIEE gives a lot of formatting options by letting us write javascript/HTML code in a spectrum of places such as narrative, static view, text’s in dashboards, data format tab of columns etc.
I am sure you can list a lot more examples of places where we can write javascript/HTML in OBIEE.
