Hello,

I was trying the examples of the book. I made ant and everything seems to have compiled correctly, but now I'm getting this:

I have the latest JDK (jdk-7u45-windows-i586.exe). What am I missing?

Thanks!

Also happens with JDK 7 update 45, when launching the app in chapter 2 (see page 53 at the top).
The problem seems to be that the system class path delegation (described in page 56 in the grey sidebar) is not working. The solution is to create a bundle with rt.jar which contains the javax.swing package and this add this bundle to the wanted application. An interesting exercise to do.
The book is from 2011 so some things will not work in Nov 13 or February 14...

Even better than my previous answer:
just download the last version of the book's source code using the instructions at https://code.google.com/p/osgi-in-action/source/checkout
Everything should work with Java 7 (well, issues are reported for chapter 6....)
At least now chapter 2 works for me (p. 53) whereas it did not before.

It works perfectly with java8, but it does not work with java 8

I've updated the example launcher to include a new profile for Java8:

https://code.google.com/p/osgi-in-action/source/detail?r=38

which should solve the problem.
