GlassFish Survey - Top Migrations to GF are from Tomcat and JBoss

Last month we ran a GlassFish Adoption Survey. Our main intention was to learn about Migration patterns on the GlassFish server. Although it was a totally self-selected, unscientific, survey, we thought it would collect some interesting insights which we could then use for a more formal survey later in the year.

With those caveats, here are the highlights:


• Where they migrated from (%):
Apache Tomcat (21.2%), JBoss (15.8%), WebSphere (5.4%), .NET (4.9%), WebLogic (3.4%)...

• Major reason to switch to GlassFish (1-10):
Cost reduction (8.16), Reduce vendor lock-in (7.68), Developer Productivity (7.58), Better quality (7.14), Improved performance (6.83), Reduced complexity (6.67)...

• Biggest benefit of for-fee support (1-10):
Patches/Updates (8.23), Support (7.4), Enterprise Mgr (6.34), Indemnification (4.27), Others (4.55)

Mostly what I was expecting, although I thought there would be fewer WAS and more WLS migrations. Looking forward to an improved version of the survey later in the year.

Evans Users Choice on IDE Available - Rational, Visual Studio, NetBeans


Evans Data just published their User's Choice on Software Development Environments. The survey asks for satisfaction of the respondents on the IDE features they used and weights them based on the aggregated priorities to determine satisfaction indexes.

The overall satisfaction rankings are: IBM's Rational Tools, MS's Visual Studio, NetBeans, JDeveloper, Sun Studio, Delphi, IntelliJ, Eclipse.

Note: my biggest issue with the EDC Users' Choice methodology is that they do not weigh in number of users for a given option, not do they disclose enough data to assess the relevance of the samples. So, as far as I've been able to determine, a few very happy customers can give a small, narrow, vendor the top ranking. Another caution area is the weights assigned to each feature to compute the overall ranking, but that is easier to navigate by using the per-feature rankings that are included in the report. As always, if you are interested in the topic, I recommend you to check out the report for details.

... Sparklines on Jersey, Servlet 3.0, Profiling GFv2, Survey Methodologies, and Barça in Miami

A compilation of today's news of interest:

Radio Receiver Icon

From Jersey in honor of the recent Jersey 1.0 Release: Paul writes about a new rev of the set of Jersey Samples (browse) that includes some implementation of Sparklines (and, as a Tufte fan... thanks!). And, Marc has been quoted in SD Times about JAX-RS and SOAP; read what he actually says, ignore the title "Sun moving away from SOAP"; we do both SOAP and REST.

Servlet 3.0 is getting closer to a Public Draft (with the rest of JavaEE 6), and Deepa has published a Intro to Servlet 3.0 at Java.Net. Some of the details apply to the old draft, so be sure to check Rajiv's comments.

Performance is always a hot topic, so check this note from one of our performance top guys, Binu John, on Profiling GFv2 with Sun Studio.

Rich's Comment on an EDC Report on AppServer Rankings started a fairly active TSS thread. As I wrote in my Comment at Savio's blog, the report is really a "User Satisfaction Survey", and, without more data, it is hard to interpret beyond that. BTW, if you download the report, consider agreeing to taking the survey and add your voice to their sample set.

And now, for the topic most of the world cares the most: Futbol, Barça has announced that they want to start a club in Miami. Check Marca, NYTimes or, Straight from the Source.

The MySQL community is counting its ranks

Piercing the fog

The MySQL Community is taking charge of counting its own ranks, by means of a survey with the purpose of measuring the usage of the world most popular open source database.

The proposal comes from Keith Murphy, editor of the MySQL Magazine, which should host the results in July.

More attention to this survey is coming from Lenz Grimmer MySQL Community Manager for EMEA, and Mark Schoonover, who is co-author of the survey. I also chimed in.
