4.6. Running Red Hat JBoss Data Grid in Karaf (OSGi)
Apache Karaf is a powerful, lightweight OSGi-based runtime container into which components and applications are deployed. OSGi implements a dynamic component model that does not exist in standalone JVM environments. OSGi containers such as Karaf include a rich set of tools for managing the life cycle of an application.
All dependencies between individual modules, including version numbers, must be explicitly specified. Where more than one class of the same name exists, the strict rules of OSGi specify which of the classes will be used by your bundle.
The Red Hat JBoss Data Grid Hot Rod client can be run in an OSGi-based container such as Karaf.
Use the path in the JBoss Data Grid Maven repository to set up Karaf. Additionally, JBoss Data Grid requires a
features file, located in org/infinispan/infinispan-remote/${VERSION}. This file lists all dependencies for the Hot Rod client in OSGi, while also making it simpler to install the feature into Karaf (version 2.3.3 or 3.0).

Red Hat JBoss Data Grid's Hot Rod feature is installed in Karaf as follows:
Prerequisite
Configure the Red Hat JBoss Data Grid Maven Repository.
Procedure 4.3. Install the Hot Rod Feature in Karaf
Karaf 2.3.3
For Karaf 2.3.3 use the following commands:karaf@root> features:addUrl mvn:org.infinispan/infinispan-remote/${VERSION}/xml/featureskaraf@root> features:addUrl mvn:org.infinispan/infinispan-remote/${VERSION}/xml/featuresCopy to Clipboard Copied! Toggle word wrap Toggle overflow karaf@root> features:install infinispan-remote
karaf@root> features:install infinispan-remoteCopy to Clipboard Copied! Toggle word wrap Toggle overflow - Verify that the feature was successfully installed as follows:
karaf@root> features:list //output
karaf@root> features:list //outputCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Karaf 3.0.0
For Karaf use the following commands.karaf@root> feature:repo-add mvn:org.infinispan/infinispan-remote/${VERSION}/xml/featureskaraf@root> feature:repo-add mvn:org.infinispan/infinispan-remote/${VERSION}/xml/featuresCopy to Clipboard Copied! Toggle word wrap Toggle overflow karaf@root> feature:install infinispan-remote
karaf@root> feature:install infinispan-remoteCopy to Clipboard Copied! Toggle word wrap Toggle overflow - Verify that the feature was successfully installed:
karaf@root> feature:list
karaf@root> feature:listCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Alternatively, use the-icommand parameter to install the Hot Rod Client feature using the following:karaf@root()> feature:repo-add -i mvn:org.infinispan/infinispan-remote/${VERSION}/xml/featureskaraf@root()> feature:repo-add -i mvn:org.infinispan/infinispan-remote/${VERSION}/xml/featuresCopy to Clipboard Copied! Toggle word wrap Toggle overflow
The Red Hat JBoss Data Grid JAR files contain the required OSGi manifest headers and are used inside OSGi runtime environments as OSGi bundles. Additionally, the required third-party dependencies must be installed. These can be installed individually, or altogether via the
features file, which defines all required dependencies.
To install bundles using the
features file:
- Register the feature repositories inside Karaf.
- Install the features contained in the repositories.
Procedure 4.4. Installing bundles using the features file
Start the Karaf console
Start the Karaf console using the following commands:cd $APACHE_KARAF_HOME/bin ./karaf
$ cd $APACHE_KARAF_HOME/bin $ ./karafCopy to Clipboard Copied! Toggle word wrap Toggle overflow Register a feature repository
Register a feature repository as follows:- For Karaf 2.3.3:
karaf@root()> features:addUrl mvn:org.infinispan/infinispan-embedded/${VERSION}/xml/featureskaraf@root()> features:addUrl mvn:org.infinispan/infinispan-embedded/${VERSION}/xml/featuresCopy to Clipboard Copied! Toggle word wrap Toggle overflow karaf@root> features:install infinispan-embedded
karaf@root> features:install infinispan-embeddedCopy to Clipboard Copied! Toggle word wrap Toggle overflow - For Karaf 3.0.0:
karaf@root()> feature:repo-add mvn:org.infinispan/infinispan-embedded/${VERSION}/xml/featureskaraf@root()> feature:repo-add mvn:org.infinispan/infinispan-embedded/${VERSION}/xml/featuresCopy to Clipboard Copied! Toggle word wrap Toggle overflow karaf@root> feature:install infinispan-embedded
karaf@root> feature:install infinispan-embeddedCopy to Clipboard Copied! Toggle word wrap Toggle overflow
Result
JBoss Data Grid runs in library mode using Karaf.
The URL for feature repositories is constructed from the Maven artifact coordinates using the following format:
mvn:<groupId>/<artifactId>/<version>/xml/features
mvn:<groupId>/<artifactId>/<version>/xml/featuresImportant
The JPA Cache Store is not supported in Apache Karaf in JBoss Data Grid 6.6.
Important
Querying in Library mode (which is covered in the Infinispan Query Guide) is not supported in Apache Karaf in JBoss Data Grid 6.6.
