Installing an OSGi Bundle

You can install an OSGi Bundle by using the OSGI Bundles portlet on the administration console with the following steps:

1. Click Browse to specify the location of the bundle you want to install.
2. (Optional) Input a non-negative integer into the Start Level field to set a start level for your bundle. By default, the start level of a bundle is set to 60.
3. (Optional) Select the Start check box if you want to start the bundle after installation.
4. Click Install.

Each OSGi Bundle is associated with a start level that enable the server to control the relative starting and stopping order of bundles. Only bundles that have a start level less or equal to the active start level of the server framework must be active. Usually, a bundle with a smaller start level tend to be started earlier.

Managing the Status of OSGi Bundles

The OSGI Bundles portlet displays the installed OSGi Bundles by different groups and their status in the table under the installation area. You can start, stop and uninstall the bundles listed in this table.

The table includes the following sections:

1. Id: This column displays the bundle Id which is unique for each bundle. The bundles in the table are sorted according to the ascending order of their Ids. This listing order complies with the starting order of the bundles. The bundles with smaller start levels tend to have smaller Id numbers.
2. Symbolic Name: This column displays the Symbolic Name of each bundle. This attribute is set by the Bundle-SymbolicName header in the MANIFEST.MF file in the bundle.
3. Version: This column displays the version of each bundle, which is set by the Bundle-Version header in the MANIFEST.MF file in the bundle.
4. State: This column displays the state of each bundle.
   • Bundles that are started are shown as Active. You can stop the bundle by using the Stop button.
   • Bundles that are stopped are shown as Resolved. You can start the bundle by using the Start button.
5. Utilities: This column displays the actions you can perform to view different information of each bundle.

By default, all installed bundled are listed when you open the OSGi portlet. However, you can choose to show only specific group of bundles:

• Select WAB to list web bundles only;
• Select Blueprint to list blueprint bundles only;
• Select System to list system bundles only, the start level of system bundle must be less than 50;

The following are actions listed within Utilities column, and which you can perform to view the information of each bundle:
