Pentaho Reporting Review

As promised in my post, "Pentaho Reporting 3.5 for Java Developers First Look", I've taken the time to thoroughly grok Pentaho Reporting 3.5 for Java Developers by Will Gorman [direct link to Packt Publishing][Buy the book from Amazon]. I've read the book, cover-to-cover, and gone through the [non-Java] exercises. As I said in my first look at this book, it contains nuggets of wisdom and practicalities drawn from deep insider knowledge. This book does best serve its target audience, Java developers with a need to incorporate reporting into their applications. But it is also useful for report developers who wish to know more about Pentaho, and Pentaho users who wish to make their use of Pentaho easier and the resulting reporting experience richer.

The first three chapters provide a very good introduction to Pentaho Reporting and its relationship to the Pentaho BI Suite and the company Pentaho, historical, technical and practical. These three chapters are also the ones that have clearly marked sections for Java specific information and exercises. By the end of Chapter Three, you'll have installed Pentaho Report Designer, and built several rich reports. If you're a Java developer, you'll have had the opportunity to incorporate these reports into both Tomcat J2EE or Swing web applications. You'll have been introduced to the rich reporting capabilities of Pentaho, accessing data sources, the underlying Java libraries, and the various output options that include PDF, Excel, CSV, RTF, XML and plain text.

Chapters 4 through 8 is all about the WYSIWYG Pentaho Report Designer, the pixel-level control that it gives you over the layout of your reports, and the many wonderful capabilities provided by Pentaho Reporting from a wide range of chart types to embedding numeric and text functions, to cross-tabs and sub-reports. Other than Chapter 5, these chapters are as useful for a business user creating their own reports, as it is for a report developer. Chapter 5 is a very deep dive, very technical look at incorporating various data sources. The two areas that really stand out are the charts (Chapter 6) and functions (Chapter 7).

There are a baker's dozen types of charts covered, with an example for each type. Some of the more exotic are Waterfall, Bar-Line, Radar and Extended XY Series charts.

There are hundreds of parameters, functions and expressions that can be used in Pentaho Reports, and Will covers them all. The formula capability of Pentaho Reporting follows the OpenFormula standard, similar to the support for formulæ in Microsoft Excel, and the same as that followed by OpenOffice.org. One can provide computed text or numeric values within Pentaho reports to a fairly complex extent. Chapter 7 provides a great introduction to using this feature.

Chapters 9 through 11 are very much for the software developer, covering the development of Interactive Reports in Swing and HTML, the use of Pentaho's APIs and extension of Pentaho Reporting capabilities. It's all interesting stuff, that really explains the technology of Pentaho Reporting, but there's little here that is of use to the business user or non-Java report developer.

The first part of Chapter 12, on the other hand, is of little use to the Java developer, as it shows how to take reports created in Pentaho Report Designer and publish them through the Pentaho BI-Server, including formats suitable to mobile devices, such as the iPhone. The latter part of Chapter 12 goes into the use of metadata, and is useful both for the report developer and the Java developer.

So, as I said in my first look, the majority of the book is useful even if you're not a Java developer who needs to incorporate sophisticated reports into your application. That being said, Will Gorman does an excellent job in explaining Pentaho Reporting, and making it very useful for business users, report designers, report developers and, his target audience, Java developers. I heartily recommend that you buy this book. [Amazon link]

Pentaho Reporting 3.5 for Java Developers First Look

I was approached by Richard Dias of Packt Publishing to review "Pentaho Reporting 3.5 for Java Developers" written by Will Gorman. (Link is to Amazon.com)

Hi Joseph,

My name is Richard Dias and I work for Packt Publishing which specializes in publishing focused IT related books.

I was wondering if you would be interesteed in reviewing the book "Pentaho Reporting for Java Developers" written by Will Gorman.

- Richard Dias

After some back and forth, I decided to accept the book in exchange for my review.

Hi Joseph,

Thanks for the reply and interest in reviewing the book. I have just placed an order for a copy of the book and it should arrive at your place within 10 days. Please do let me know when you receive it.

I have also created a unique link for you. It is http://www.packtpub.com/pentaho-reporting-3-5-for-java-developers?utm_source=press.teleinteractive.net&utm_medium=bookrev&utm_content=blog&utm_campaign=mdb_001537. Please feel free to use this link in your book review.

In the meanwhile, if you could mention about the book on your blog and tweet about the book, it would be highly appreciated. Please do let me know if it is fine with you.

I’m also sending you the link of an extracted chapter from the book (Chapter 6 Including Charts and Graphics in Reports). It would be great if you could put up the link on your blog. This would act as first hand information for your readers and they will also be able to download the file.

Any queries or suggestions are always welcome.

I look forward to your reply.

Best Regards,

Richard

Shortly thereafter, I received notification that the book had shipped. It arrived within two weeks.

Of course, I've been too busy to do more than skim through the book. Anyone who follows me as JAdP on Twitter knows that in the past few weeks, I've been:

  • helping customers with algorithm development and implementing Pentaho on LucidDB,
  • working with Nicholas Goodman with his planning for commercial support of LucidDB through Dynamo Business Intelligence, and roadmaps for DynamoDB packages built on LucidDB's plugin architecture, and
  • migrating our RHEL host at ServerBeach from our old machine to a new one, while dealing with issues brought about by ServerBeach migrating to Peer1's tools.

None of which has left any time for a thorough review of "Pentaho Reporting for Java Developers".

I hope to have a full review up shortly after the holidays, which for me runs from Solstice to Epiphany, and maybe into the following weekend.

First, a little background. Will Gorman, the author, works for Pentaho, in software engineering, as a team lead, and works primarily on Pentaho Reporting products, a combination of server-side (Pentaho BI-Server), Desktop (MacOSX, Linux and Windows platforms) and Web-based software (Reporting Engine, Report Designer, Report Design Wizard and Pentaho Ad Hoc Reporting), which stems from the open source JFreeReport and JFreeChart. While I don't know Will personally, I do know quite a few individuals at Pentaho, and in the Pentaho community. I very much endorse their philosophy towards open source, and the way they've treated the open source projects and communities that they've integrated into their Pentaho Business Intelligence Suite. I do follow Will on Twitter, and on the IRC Freednode Channel, ##pentaho.

I myself am not a Java Developer, so at first I was not attracted to a book with a title that seemed geared to Pentaho Developers. Having skimmed through the book, I think that the title was poorly chosen. (Sorry Richard). I find that I can read through the book without stumbling, and that there is plenty of good intelligence that will help me better server and instruct my customers through the use of Pentaho Report Designer.

My initial impressions are good. The content seems full of golden nuggets of "how-tos" and background information not commonly known among the Pentaho community. Will's knowledge of Pentaho Reporting and how it fits into the rest of the Pentaho tools, such as KETTLE (Pentaho Data Integration) and Mondrian (Pentaho Analysis), along with a clear writing style makes all aspects of Pentaho more accessible to the BI practitioner, as well as those that wish to embed Pentaho Reporting into their own application.

This book is not just for Java developers, but for anyone who wishes to extend their abilities in BI, Reporting and Analysis, with Pentaho as an excellent example.

I'll be following up with the really exciting finds as I wend my way through Will's gold mine of knowledge, and, will do my best to fulfill my promise of a full review by mid-January.

You can also click through the Chapter 6 (a PDF) as mentioned in Richard's email.

Thank you, Richard. And most especially, thank you, Will.

OpenRPT 2.0 Available for Download

OpenMFG announced the availability of OpenRPT 2.0 on 2006 December 20. From their forum...

"OpenRPT 2.0 was retooled from the ground up to take full advantage of the underlying Qt 4 framework. Qt is an open source, comprehensive development framework that includes an extensive array of features, capabilities and tools that enable development of high-performance, cross-platform rich-client and server-side applications. Among the new OpenRPT features enabled by updating from Qt 3 to Qt 4 is the ability to export to Adobe PDF natively for both the OpenRPT API and the rendering application.

"Other new features include support for generic ODBC database connections (the first release only supported the open source PostgreSQL database - and native PostgreSQL support continues in 2.0); enhanced page break functionality; and power tools for developers such as command-line arguments and parameters, multiple document printing, and advanced error trapping.

"Since it was released as an open source project in 2005, OpenRPT has been downloaded over 30,000 times..."end quotation

Current Version Confusion for JasperReports iReports

We're a bit confused as to what is the current version of JasperSoft's JasperReports and iReport. SourceForge.net has version 1.3.0 of both JasperReports and iReport available for download, but with the disclaimer that...

JasperReports, the market leading open source business intelligence and reporting engine. This project is being moved to http://www.jasperforge.org/. This project is the home for all things Jasper, Reports, Analysis, Server, and Intelligence.end quotation
-- JasperReports Java Reporting home on SourceForge

The only downloads from JasperForge seem to be for documentation. Going to JasperSoft's site, there is only reference to the November release of 1.2.8, but the downloads page, after a free registration, brings you back to SourceForge.net and the 1.3.0 versions of the software.

I guess the holidays are just delaying the official release announcements. Enjoy.

jFreeReport Added

Lance Walter, VP of Marketing at Pentaho, let us know that we had neglected to include jFreeReport in our blogroll and lens. I plagerized his email in describing jFreeReport in the lens links to reporting tools.

This site is a great resource. A consultant referred me to it and said it was the best consolidated source of information on osbi that he had found.

I had one suggestion. In the OS Reporting Projects - would you consider adding a link to JFreeReport? www.jfree.org/jfreereport . We use it as part of Pentaho, but it's also a standalone java reporting library with some pretty nice capabilities and a decent community around it.end quotation

At the beginning, The Open Source Solutions Blog was a companion to the Open Source Solutions for Business Intelligence Research Project, and book. But back in 2005, we couldn't find a publisher. As Apache Hadoop and its family of open source projects proliferated, and in many ways, took over the OSS data management and analytics world, our interests became more focused on streaming data management and analytics for IoT, the architecture for people, processes and technology required to bring value from the IoT through Sensor Analytics Ecosystems, and the maturity model organizations will need to follow to achieve SAEIoT success. OSS is very important in this world too, for DMA, API and community development.
