Java 9 was officially released last week and testing this brand new major version of Java with Knopflerfish shows the following:<br />
<br />
Knopflerfish runs fine on Java 9. The entire Knopflerfish test suite passes on Java 9. Should there be issues please report them to us at: <a href="https://github.com/knopflerfish/knopflerfish.org">https://github.com/knopflerfish/knopflerfish.org</a> using the issue tracker.<br />
<br />
Knopflerfish 6 does not however build with JDK9. We are now going over the issues and a new release can be expected soon. Most of the issues seem to be related to 3rd party libraries used in Knopflerfish, e.g. asm, ProGuard.<br />
<br />
Please note that you will get warning from the desktop bundle because of the changes in Java 9 in regards to using reflection.<br />

The Knopflerfish team is pleased to announce the release of Knopflerfish 5.1 now available for <a href="http://www.knopflerfish.org/download.html">download from the Knopflerfish web site.</a><br />
<br />
Knopflerfish version 5.1 is the first minor release of Knopflerfish implemented according to the OSGi Release 5 specification and includes several minor enhancements as well as all bug fixes made since KF 5.0 was released. The 5.1 release also includes fixed related to Java 8 and Knopflerfish 5.1 passes all tests on Java 7 and 8, as well as older Java versions, and embedded Java profiles.<br /><br />The new key features in Knopflerfish OSGi 5.1 are:<br />

<br />
<br />
What this means is that if there is a Resolver service available, clicking either the button to <i>Install from repository</i> or to <i>Install and start from repository</i> (circled in the picture below) will show a pop-up question asking if you want to resolve the selected resource and install its required dependencies.
<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjE4Z3n5jxlX7HLKHQhIdAvGHx-eT7YhgOfZIhKspP834H__3pj_fVSdte1CwgByXdpWHuVSfNh2w479uAkEvLiUJdnhVJpLHGuD6Yk-ojPFjvqLtF3aZ1KolfRV05MtHUXiIeCRnGxPVk/s1600/Repository_Desktop_Resolve.gif" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjE4Z3n5jxlX7HLKHQhIdAvGHx-eT7YhgOfZIhKspP834H__3pj_fVSdte1CwgByXdpWHuVSfNh2w479uAkEvLiUJdnhVJpLHGuD6Yk-ojPFjvqLtF3aZ1KolfRV05MtHUXiIeCRnGxPVk/s400/Repository_Desktop_Resolve.gif" /></a></div>
<br />
Until the next full release this feature is available if you build from <a href="https://www.knopflerfish.org/svn/knopflerfish.org/trunk/">https://www.knopflerfish.org/svn/knopflerfish.org/trunk/</a>.<br />
<br />
In order to try this you also need to install an implementation of the Resolver Service.
There is one available at <a href="http://repo2.maven.org/maven2/org/apache/felix/org.apache.felix.resolver/1.0.0/org.apache.felix.resolver-1.0.0.jar">org.apache.felix.resolver-1.0.0.jar</a>.<br />
To make things easier you can uncomment the following line in the init.xargs file in the osgi directory:
<br />
<pre><code>
# Uncomment the following line to add Resolver support
#-istart http://repo2.maven.org/maven2/org/apache/felix/org.apache.felix.resolver/1.0.0/org.apache.felix.resolver-1.0.0.jar

What this means is that the install command now has an optional [-r] flag that will try to find and install (and start if that option is given) the recursive dependencies of the bundle you are trying to install.<br />
<br />

But in some contexts you need to turn security on. To overcome the set up hassle most users encounter the first time they get exposed to the ConditionalPermissionAdmin service in OSGi, and security in general in Java, we have created a hands on <a href="http://www.knopflerfish.org/snapshots_trunk/current_trunk/docs/osgi_with_security.html">guide and tutorial on how to run Knopflerfish with Security turned On. </a><br /><br />The small tutorial also includes some example bundles, including full sources. The examples are checked in to the KF SVN:<br /><a href="https://www.knopflerfish.org/svn/knopflerfish.org/trunk/osgi/bundles_examples/cpa/">https://www.knopflerfish.org/svn/knopflerfish.org/trunk/osgi/bundles_examples/cpa/</a><br /><br />/ChristerChrister Larssonhttp://www.blogger.com/profile/05440980980062127245noreply@blogger.com0tag:blogger.com,1999:blog-4816709533104512585.post-22311506174613134842011-04-15T00:18:00.000+02:002011-04-15T00:29:45.217+02:00Knopflerfish is now on TwitterKnopflerfish is now on Twitter:<br /><a href="http://twitter.com/knopflerfish">http://twitter.com/knopflerfish</a><br /><br />Be sure to follow us for Knopflerfish Updates Great and Small.Christer Larssonhttp://www.blogger.com/profile/05440980980062127245noreply@blogger.com0tag:blogger.com,1999:blog-4816709533104512585.post-56897779903630406402011-03-10T19:02:00.000+01:002011-03-10T19:07:05.699+01:00Knopflerfish web site temporarily downThe Knopflerfish web site is temporarily unavailable.

KF3 fully implements the core and service compendium functions according to OSGi R4 v4.2. The <a href="http://www.knopflerfish.org/kf3_osgi_r4_v4.2.html"> KF3 overview page </a> describes the development of KF3 in more detail. KF3 also includes several other improvements and fixes.
