Liferay theme creation basic commands/tools to setup or configuration
Install
Node.js
1.
Find the node-[version]-[os] installer from node site.
2.
Run the
installer for your operating system and follow the instructions.
3.
Open a Command
Prompt/Terminal window.
4.
Run node -v in your command line to verify your
installation once you have installed node.js and npm.
o
The node version should be
8.x.x
5.
Run npm -version to double-check the appropriate version is
installed.
o
The npm version should be
6.x.x
Install
Yeoman and Gulp Dependencies
1.
Open the
command line.
2.
Type npm install -g yo gulp.
o Note:
Users on OSX or Linux will need administrative access to run this command. To
do this, they may need to run sudo before the command.
3.
Press Enter.
This
should have installed the Yeoman and gulp global dependencies. Now we can go
ahead and install the Liferay Theme Generator. If you are running Windows, you
should also install Windows Build Tools before Installing the Liferay Theme
Generator. Let's do this next.
Install
the Liferay Theme Generator
1.
Type npm install -g generator-liferay-theme in the Command
Prompt/Terminal.
o Note:
Like before, Users on OSX or Linux may need to run sudo before the command.
2.
Press Enter.
3.
Type yo in the command line to see that the generator
is installed.
4.
Press Enter.
5.
Type Y
or N if an initial prompt asks to collect data.
6.
Press Enter.
7.
Choose Get
me out of here!.
8.
Press Enter.
Liferay OSGi framework
1. OSGi Framework provides runtime environment (container) and development environment (annotations, dependency injection)
Note: @Reference works for concrete classes only. That means not work for interface and abstract classes (getting null as object value)
2. Component lifecycle - active, activated and deactivated
3. Component registered in OSGi Container and service registered in Service registry
4. invoke method (getTime()) from gogo shell - "osgi.command.function=getTime", "osgi.command.scope=custom"
5. We can determine multiple implementations for single interface by using 1. ranking, 2. target
6. Export-Package & Import-Package vs Provide-Capability & Require-Capability
7. Bundle lifecycle - 1. Installed, 2. Resolved, 3. Active, 4.
8. Spring beans generated by liferay service builder by which annotation can use/reference it ?
sol : @ServiceReference annotation.
Explanation : AssignmentServiceImpl is not OSGi component class. Hence, need to use @servicereference.
9. MVC Commands take care of the portlet life-cycle and interaction b/w UI & Back-end.
a. MVC Commands are wired to a certain portlet life-cycle (render, action & resource)
b. They respond to certain 'mvc.command.name' defined in component properties.
c. they register to a certain portlet with the 'javax.portlet.name' component property.
10. To make silence the generated API under any xxxxLocalServiceImpl classes, simply override that API by @override and define to throw UnsupportedOperationException
11. what is the bundle State when its working as expected after deployment of fragment module ?
Sol : Resolved
12. how many ways override JSPs and what are those ?
Sol : 2 ways and a. override that JSP by creating fragment module. b. update that JSP by creating render filter and customize the JSP output.
13. What is LifecycleAction and why will use it?
Sol : LifecycleAction allows us to customize liferay's application by using events. Events are 1. application.startup.events, 2. prelogin.events, 3. postlogin.events and etc.,
14. what is the use of servicewrapper?
Sol : By using Servicewrapper we can customize service methods either pre or post execution.
15. How we can override struts action?
Sol : Our custom component class should extends BaseStrutsAction and property is "path=/portal/logout"
Sample :
Sol : Our custom component class should extends BaseMVCActionCommand, and property is property = {
"javax.portlet.name=" + DLPortletKeys.DOCUMENT_LIBRARY,
"javax.portlet.name=" + DLPortletKeys.DOCUMENT_LIBRARY_ADMIN,
"javax.portlet.name=" + DLPortletKeys.MEDIA_GALLERY_DISPLAY,
"mvc.command.name=/document_library/edit_folder",
"service.ranking:Integer=100"
}
17. Model entity listener ?
Sol : Events we are able to listen for when an action on a Model Entity is executed in the persistence layer. There are a few use cases for Model Listeners such as an Audit Listener, Cache Clearing Listener, and Validation Listener. The use case we are implementing is the fourth use case, the Entity Update Listener.
Snippet : @Component(immediate = true, service = ModelListener.class)
public class UserPostUpdateModelListener extends BaseModelListener<User> {
}
18. message bus listener ?
2. Component lifecycle - active, activated and deactivated
3. Component registered in OSGi Container and service registered in Service registry
4. invoke method (getTime()) from gogo shell - "osgi.command.function=getTime", "osgi.command.scope=custom"
5. We can determine multiple implementations for single interface by using 1. ranking, 2. target
6. Export-Package & Import-Package vs Provide-Capability & Require-Capability

Sol : By using Servicewrapper we can customize service methods either pre or post execution.
15. How we can override struts action?
Sol : Our custom component class should extends BaseStrutsAction and property is "path=/portal/logout"
Sample :
1. Step 1 : @Component(2. immediate = true,3.property = {
4. "path=/portal/logout"5.},
6.service = StrutsAction.class)
1.Step 2 : @Override
2. public String execute(
3. StrutsAction originalStrutsAction, HttpServletRequest request,
4. HttpServletResponse response)
5. throws Exception {
6.
7. System.out.println("Overriding the Portal Logout Action!");
8.
9. originalStrutsAction.execute(request, response);
10.
11. response.sendRedirect("https://university.liferay.com");
12.
13. return null;
14. }
Sol : Our custom component class should extends BaseMVCActionCommand, and property is property = {
"javax.portlet.name=" + DLPortletKeys.DOCUMENT_LIBRARY,
"javax.portlet.name=" + DLPortletKeys.DOCUMENT_LIBRARY_ADMIN,
"javax.portlet.name=" + DLPortletKeys.MEDIA_GALLERY_DISPLAY,

Gogo shel commands
Gogo shell is available inside of the OSGi Container.
Gogo shell commands :
1. lb (to see list of bundles)
2. start <<bundle-id>>
3. stop <<bundle-id>>
4. headers <<bundle-id>>

4. headers <<bundle-id>>
OSGi Basics
OSGi is specification and set of standards to develop Java based modular applications.
1. OSGi Framework : It is runtime (OSGi Container) & development environment.
2. Bundle : Basic unit to deploy into the OSGi container. It is a JAR file which contains executable code and OSGi headers in its MANIFEST.MF file.
Bundle = MANIFEST.MF + Java classes + Resources.
a. Symantic versioning : Major . Minor . Micro - Qualifier (3.0.0-BETA).
Eg. [1.2, 3.0) (means version 1.2 onwards and upto 3.0 not included 3.0 version)
b. Bundle lifecycle managed by BundleActivator.
States are :
1. installed (after added into the container), 2. Resolved (all imported dependencies are resolved ), 3. Starting, 4. Active, 5. Stopping, 6. Unistalling.
3. Component : It is an object (java class) which has set of functionalities. It is managed by component framework.
Component Lifecycle : 1. active, 2. activated. 3. deactivated
4. Service : It is a component registered to OSGi Container 'service registry'.
Implements an interface and referenced by its interface in the OSGi Container.

Coding standards to develop artifact
1. If we get any errors, while performing add/update operations then return previous request & response (which contains user entered data). By using the snippet:
PortalUtil.copyRequestParameters(request, response);
2. If necessary we need to write custom validator, to validate custom entities.
3. While writing implementation to CRUD operations in Liferay's service builder xxxxLocalServiceImpl class, make sure that you are not re-writing available operations in xxxxLocalServiceBaseImpl.
xxxLocalServiceBaseImpl CRUD operations are available. We are extending it in our xxxxLocalServiceImpl. So, no need to write again those CRUD operations on xxxxLocalServiceImpl class.
