Users need to apply different external JAR files to the existing Carbon server, to enhance or introduce new features to the Carbon application. OSGi bundles are used to implement WSO2 Carbon. As a result, if needed to extend a platform the OSGi bundles need to be dropped into the Carbon server.
To add external libraries:
The users are allowed to apply JARs to various directories as required. The WSO2 Carbon OSGi repository is available in the <CARBON_HOME>/repository/components directory . When extracting a Carbon or Carbon-based product, <CARBON_HOME> is the folder that gets generated. The user has to manually insert all the corresponding entries in these components to the bundles.info file at the following location:
<CARBON_HOME>/repository/components/$profile/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info
Note that "$profile" is the default value.
Use the following directories to drop external libraries to the Carbon Server:
| Directory | Description |
|---|---|
<CARBON_HOME>/repository/components/dropins | OSGi bundles which needs to be applied. |
<CARBON_HOME>/repository/components/lib | Dropped JAR files that will be converted to OSGi bundles at startup and copied to the dropins directory. |
<CARBON_HOME>/repository/components/extensions | Dropped JAR files that will be converted to OSGi Framework Extension bundles at startup and copied to the dropins directory. |
After adding all the required libraries, restart the server to apply the changes.
