dm Server 2.0.0.M5

Posted on October 12th, 2009 by Ben Hale in OSGi, dm Server.

dm Server 2.0.0.M5 is now available and can be downloaded from here.

We're getting towards the end of the 2.0.0 release cycle so most of the work in this milestone is focused on locking down the user interaction model. Take a look at the M5 release notes for the full details of what we've been working on. Please keep your feedback coming as comments on our blog, in the forums and on JIRA.

Please also watch the blog for detailed posts on many of the new features referenced in this New and Noteworthy.

New and Noteworthy

Deploying Configuration Files

Properties files can now be deployed in either the pickup directory or in any configured repository. The content of these files is then accessible in OSGi's ConfigurationAdmin at a PID specified as the file's name without the .properties extension.

Plan Attributes and Properties

Plans can now have globally defined attributes used for substitution.

<attributes>
	<attribute name="version" value="[1.0.0, 2.0.0)"/>
</attributes>

<artifact type="bundle" name="org.springframework.context.support" version="${version}"/>

Artifacts within plans can have properties defined which are translated into Bundle manifest headers at deployment time.

<artifact type="bundle" name="my.webapp" version="[1.0.0, 2.0.0)">
	<property name="Web-ContextPath" value="/foo"/>
</artifact>

Admin Console

The Artifacts page of the admin console has been spruced up to render the dependencies of user installed artifacts as trees. In addition, each level of these trees is lazily loaded improving load-time performance.

Admin Console

Command-line Shell

dm Server now ships with a command line shell to replace the Equinox console that was previously used. This console is accessible locally with the -shell startup command.

$ bin/startup.sh -shell
<KE0001I> Kernel starting.
<KE0002I> Kernel started.
<SH0001I> dm Kernel ssh shell available on port 2402.

You can also access this command line shell via SSH using the same login credentials that are used for web and JMX access.

$ ssh -p 2402 admin@localhost

Infrastructure moves

We've also made some changes to various parts of the infrastructure of dm Server. First, the repository area has been simplified to only have an ext and a usr folder. The usr folder is configured as a watched repository meaning that you do not need to restart the server to reference bundles that have been added there.

New Repository

The config/ directory has been flattened and the credential store and keystore have been moved. The keystore now resides in config/keystore. The credential store now resides in config/com.springsource.kernel.users.properties and specified users and roles in a properties file format.

Runnable dm Kernel

Last but not least, the dm Kernel is now a standalone runnable distribution. You can build a zip package from the source code directly or download from here.
