This plugin is only experimental and hasn't been released yet. It is not ready to be used in production applications. |
The Struts 2 OSGi plugin
Excerpt |
---|
leverages OSGi to allow Struts 2 applications to be divided into multiple jars (bundles) and managed at runtime |
Features
- Application packages can be divided into bundles
- Supports Velocity templates
Missing Features
- No GUI for bundle administration
- Probably can't access application classes from bundles, including Spring classes
- No support for any results other than Velocity
Usage
To convert your jar that contains Actions, Velocity files, and a struts.xml
file into a bundle, add a few lines in the jar's manifest.mf:
No Format |
---|
Bundle-Activator: org.apache.struts2.osgi.StrutsActivator
Export-Package: com.mycompany.myapp.actions
Bundle-Version: 1.0.0
Bundle-SymbolicName: foo.actions
|
Now the jar is ready to be deployed. Drop the jar into the /WEB-INF/classes/bundles
directory and it will automatically be installed when the application starts up.
Example
Here is how an example architecture would look:
