Did you make some logging changes to the code? Or using package provided in the article?

The problem would appear to be that the bundle which includes DefaultHttpClient isn't importing org.apache.commons.logging.

Add this to the POM

<dependency>

    <groupId>commons-logging</groupId>

    <artifactId>commons-logging</artifactId>

    <version>1.2</version>

</dependency>
