# Sample Projects for Liferay Portal
Liferay's sample projects provides bootstrap project environments for all major
build tools in common use for Java projects so that Liferay development can
start quickly and easily. These templates can be copied freely and contributions
are welcome. See the [Contribution Guidelines](#contribution-guidelines) for
more information on how to contribute new sample projects and/or documentation.## Build Tools
The template projects are categorized under two build tools:
* `liferay-workspace` - A set of Liferay projects configured to work in a
[Liferay Workspace](https://portal.liferay.dev/docs/7-2/reference/-/knowledge_base/r/liferay-workspace)
environment.
* `liferay-workspace-test-integration-sample` - A Liferay project configured to
execute Integration Tests.
* `maven` - A set of Liferay projects that can be bootstrapped onto the *Maven*
development environment.## Usage
The projects follow the Liferay Workspace project style for gradle and maven.
* `liferay-workspace` - in `gradle.properties`, Set `liferay.workspace.product`
to the target product version.
* `liferay-workspace-test-integration-sample` - The test project is in
modules/sample/sample-test folder. Run `gradlew buildService testIntegration`
in modules/sample.
* `maven` - Set the corresponding `release.portal.bom` found in
`dependencyManagement`## Contribution Guidelines
When contributing a new sample, you **must** include accompanying documentation.
### Sample Code
You can contribute additional template samples by creating the project for one
of the possible build tools and sending a pull request to
`liferay/liferay-blade-samples`. A repository admin will review the submission
and replicate the project for the other supported build tools, once the submission
is approved.### Sample Docs
You can contribute documentation by adding a `README.markdown` file to the root
folder of a sample project. This article should include the following sections:- *What does this sample do when it's deployed?*
- *What API(s) and/or code components does this sample highlight?*
- *How does this sample leverage the API(s) and/or code component?*For example, the
[Resource Bundle Override](https://portal.liferay.dev/docs/7-2/reference/-/knowledge_base/r/resource-bundle-override)
article explains the `resource-bundle-override` sample using the aforementioned
sections.## Frameworks
The template projects also demonstrate how to use various frameworks:
* Blueprint
* Declarative Services (**DS**)
* OSGi API### A Note on Blueprint
Liferay does not provide a Blueprint implementation out of the box. To use the
Blueprint modules provided in Blade, you must deploy a Blueprint implementation
such as [Apache Aries - Blueprint](http://aries.apache.org/modules/blueprint.html).
Three bundles are needed:* [Apache Aries Blueprint Bundle](http://mvnrepository.com/artifact/org.apache.aries.blueprint/org.apache.aries.blueprint/1.1.0)
* [Apache Aries Blueprint Annotation API](http://mvnrepository.com/artifact/org.apache.aries.blueprint/org.apache.aries.blueprint.annotation.api/1.0.1)
* [Apache Aries Proxy Bundle](http://mvnrepository.com/artifact/org.apache.aries.proxy/org.apache.aries.proxy/1.0.1)Simply download the bundles from [mvnrepository](https://mvnrepository.com/) and
drop them in your `osgi/modules` folder before deploying Blueprint bundles.## Liferay Extension Points and Template Projects
## Apps
### Action Command Portlet
**Template project description**: Demonstrates the `MVCActionCommand` extension
point. It integrates the action command named `greet` with portlet `greeter`. To
see how this example works, a portlet plugin with a portlet named **greeter**
(`javax.portlet.name='greeter'`) should be deployed. The command adds a key
`greeting_message` to Liferay `SessionMessages`, along with a session attribute
`GREETER_MESSAGE`. You can independently deploy the bundle
`blade.portlet.actioncommand` (i.e., refresh the bundle without the need to
redeploy the Portlet plugin).| Build tool | Link to project's source code |

`com.liferay.portal.kernel.events.SimpleAction`. Connecting a `LifecycleAction`
to a particular event is determined by the OSGi service property `key`. The
following keys are supported:* `application.shutdown.events` - fired during destruction of company instances
at portal shutdown.
* `application.startup.events` - fired during initialization of company
instances at portal start, or when a new instance is created.
* `global.shutdown.events` - fired during destruction of the portal's main
servlet.
* `global.startup.events` - fire during initialization of the portal's main
servlet.
* `layout.configuration.action.delete` - fired during destruction of a page
(Layout).
* `layout.configuration.action.update` - fired during initialization of a page
(Layout).
* `login.events.post` - fired immediately following login.
* `login.events.pre` - fired immediately prior to login.
* `logout.events.post` - fired immediately following logout.
* `logout.events.pre` - fired immediately prior to logout.
* `servlet.service.events.post` - fired following requests to the portal
(including all portlet container requests).
* `servlet.service.events.pre` - fired prior to requests to the portal
(including all portlet container requests & post login).
* `servlet.session.create.events` - fired during creation of a portal's HTTP
session.
* `servlet.session.destroy.events` - fired during destruction of a portal's HTTP
session.**Template project description**: Demonstrates a hook for `login.events.pre`.
