Guice made a good start in Japan

A DI container Guice, which is written in Java and released from Google, has fascinated Japanese Java programmers since its 1.0 release in March 8, 2007. Everyday, they write blogs about Guice and shows how much they are zealous to explore Guice. It is clear that Guice made a good start in Japan. I'll introduce what they have written in their blogs.

Many bloggers refer to the online magazine article that explains what is Guice and how we write code using Guice. This article, http://journal.mycom.co.jp/articles/2007/03/14/googleguice/, was publishd in March 14, 2007, just six days after the release. The title might be "It is just like Google to think much of the sense of balance" in English. The author emphasizes Guice would be an effective DI container to innovate into Java based system because it realizes DI by API only.

Among bloggers, committers of Seasar2, which is a de facto DI container in Japan, express concerns for Guice. One of them wrote the result of the benchmark test including Guice, Spring and Seasar2 on the web site, http://d.hatena.ne.jp/arumani/20070316 . The code used for the benchmark test is based on PerformanceComparison class distributed with other Guice source code, and its patch to the original code can be seen at http://docs.google.com/Doc?id=dd3xcjm8_6ddtd3k . According to the result, we know Guice works far faster than Spring, while Seasar2's performance is very close to Guice. The Seasar2 committer analyzes the delay might have come from the slow start of an OGNL library.

Another blogger has trasnlated the User's Guide of Guice into Japanese for a couple of days, which can be read on the blog site, "http://d.hatena.ne.jp/iad_otomamay/ ." The blogger's activity would help to accelerate increasing Guice users in Japan because most Japanese programmers are reluctant to read English documents. Of course, there are some bloggers writing code snippets by using Guice. These would also help to swell up the number of Guice users since how to make a program is interpretted in Japanese.

Current situation would be the first Guice boom raised by skilled programmers who are good at reading source code; therefore, it might take more time for ordinary Java programmers to start to use Guice. Probably, the ordinary programmers would need more documents and articles to decide to embrace it so that they don't lose the way while they are writing code. However, Guice will surely thrive after gaining large amount of users.
