+I work for SAP Business Objects in Technical Customer Assurance.  My speciality is the Software Development Kits (SDKs) that we provide with our Business Intelligence products – BusinessObjects Enterprise, Web Intelligence, Desktop Intelligence, Crystal Reports and Crystal Xcelsius.  +

+In my blog, I discuss subjects that I personally find interesting – little known or not-well-documented corners of the SDK, new functionality or new SDKs, or interesting issues that I’ve come across in a SAP Incident or SAP Developer Network forums.  +

+You’re more than welcome to suggest any topic (SAP Business Objects SDK related, of course…) that you’d like me to discuss – I have a dozen or so items on my blog to-do list, but I’m always on the hunt for anything interesting with our SDKs.+   

+*** Update: revised Flex sample to use the new suppress_response_codes feature (thanks, Bo!) to work with Internet Explorer! ***+ If you’re interested in {code:html}+Polestar in the cloud+{code} and the recently announced {code:html}+Polestar in the cloud+ API $20K IDEAtion Challenge{code}, then this blog entry may be of interest to you.   I’m going to present here a few sample codes for that API, so you’ll quickly get up to speed and have a head start on the competition! Each of the sample codes follow the same workflow: retrieve data, upload the dataset to OnDemand, then view it in +Polestar in the cloud+.  What differs is the programming language used and the data source.  The four samples are:   * C# with data retrieved from Query as a Web Service ( [Xcelsius |] SDK – Adobe Flex component. 0.2. Java with RSS Feed ( data.

h5. +Polestar in the cloud+ API Ty Miller, a Techical Director here, sent me email about a month ago asking whether I was interested in checking out a cool new Web Services API for the [BusinessObjects Labs |] project called {code:html}+Polestar in the cloud+{code}. I figured whatever Ty’s involved in is high on the hot-and-interesting scale – he’s sent a few pretty interesting Customer Support cases my way in the past – but at the time I was busy helping customers and working with {code:html}Crystal Reports for Eclipse 2.0{code} and Universe Data Access Driver Development Kit SDK (Web Intelligence XI 3.x – Reporting off the BusinessObjects Enterprise CMS Via Data Access DDK), so I had to flag his email for later action. [Rob Horne | /people/robert.horne/blog], who’s also into pretty interesting stuff, recently [blogged | Get a peek at the hottest product at SAP BusinessObjects] about +Polestar in the cloud.+  Reading his blog certainly encouraged me to check it out  (although I have to say I’m far from a Steve Nash fan), and what I found was pretty impressive.  Polestar makes the relationship between you and your data highly personal – I’ve gotten tremendous insight, and seen relationships I’ve not thought of, merely by uploading data and working with it in Polestar.  Having Polestar as part of the “Cloud” computing on Whohar – the [ |] portal – makes it that much more compelling.  Now you can upload and store your data on Whohar, and analyze it using different dashboards as well as Polestar.  Programmatic dataset management is accomplished via the Whohar RESTful ( Web Services API – you can upload, download, update and delete datasets via simple HTTP calls.  You can then invoke a URL to view a dataset in Polestar. The beauty of the API is in its simplicity – you’re able to code against it using most programming languages out there, and have a very elegant means to integrate your app with +Polestar in the cloud+. Rob kindly sent me a preview of the Whohar API docs – it’s now available publicly {code:html}here{code} – and I’ve been playing with the API since.    I’ve cleaned up some of my sample codes and present it here for your enjoyment.  I do hope it helps you in quickly working out the API workflow required to integrate your stuff with +Polestar in the cloud+. h5. Python Script with Inline DataSet Here’s a short Python ( script that I used to get a ‘feel’ for the API –

bq. *Python script uploading data to +Polestar in the clo+ud* #!/usr/bin/env python 1. 2. # 1. Upload data to Whohar and view in Polestar in the cloud #=============================================================================== import base64 import os import urllib2, cookielib import webbrowser 1. 2. URL to Whohar Dataset API and Logon Credentials # url = ‘‘ username=” 1. 2. Dataset to upload to Whohar # data = ””” # 1. Log on and send data to Whohar # datasetURL = None 1. Define HTTP Basic Authentication header string base64string = base64.encodestring(‘%s:%s’ % (username, password))[:-1] authheader = “Basic %s” % base64string 1. Define HTTP Cookie container – used to retrieve Session ID cookieJar = cookielib.CookieJar() opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cookieJar)) 1. Construct HTTP request with authentication header req = urllib2.Request(url) req.add_header(“Authorization”, authheader) 1. Send dataset to Whohar. HTTP Response to successful upload is HTTP Code 201. 2. Python throws an exception on 201, so we trap and retrieve content Location. try: handle =, data) except IOError, e: if e.code != 201: raise datasetURL = datasetURL = datasetURL[datasetURL.index(“http”):-1] 1.

Edit the top of the file to insert your logon credentials, and modify the bottom to use either the webbrowser lib or explicit launching of a web browser, and run it using the Python interpreter. You’ll note how simple the API is – the advantage of using a RESTful Web Services design. h5. C# With Data Retrieved from Query as a Web Service A bit more useful example, using C# – I wrote it on Visual Studio 2008 – that consumes data from Query as a Web Service (QaaWS), upload them to Whohar and view in +Polestar in the cloud+.  Here’s a screenshot of what you get, showing both the QaaWS client with the query, and the Polestar view of the data:   image   The query is based on the eFashion sample Universe, and Polestar is displaying the breakdown of sales revenue, quanitity of merchandise sold, and margin for stores by State.  Texas is looking pretty good (more on Texas later)… Here’s the code: bq. *C# 2008 to upload QaaWS-generated data to Polestar OnDemand* using System; using System.CodeDom; using System.CodeDom.Compiler; using System.Collections.Generic; using System.Collections.ObjectModel; using System.IO; using System.Linq; using System.Net; using System.Reflection; using System.ServiceModel.Description; using System.Text; using System.Web; namespace QaaWS2Polestar { /* Call and retrieve data from QaaWS and send to Polestar OnDemand via Whohar ( 1. 1.

    Thank you very much for your efforts. Its really great that you have initiated the work on this challenge. It also means that you have given four new ideas which perhap are really great.
  2. Anonymous
    Thanks Ted, it’s really cool demo and a very good starting point for others! 
  3. Anil Jose
    I was able to write flex code and test in Polestar OnDemand early last year. It no longer works for me. I tried the sample code which was given by Ted Ueda – not working. All of these code were working perfectly when i tried in June 2009. Did the Polestar API/input data format change? If yes, is there any documentation on these changes?


  4. Raja Panda
    Hi Ted,

    Nice post!! Got to learn a lot from it.

    I have this question though. I tried out your sample code in

    Is there a way I can upload a non-xml based file say for example a .xls file or webi (.wid) file onto whohar and display it on polestar ??
    If yes, can you give me few pointers on how I can do it ?


  5. Ranjith Kumar R
    i had tried the c# sample Program. it works fine by retrieving the data from the QaaWS but when the code upload the dataset to the polestar the dataset is not created in polestar.. please some one help me in this regard..
    i am using .net08 and c# language

    Thanks in advance..

  6. Ranjith Kumar R
    the document id is not created in the dataset parameter that has to upload in the polestar.. how to include that.. whether that cause the data not to upload in polestar..

    some one help me in this regard
