liferay technology

This problem actually stuck me for 1 hours, mainly beginning to think complex. Because the default if the site to do in-station navigation, we are implemented with JS, and Liferay page is so complex, because the portal page is composed of a portlet, each page ID composition is also very complex, so I have been doing it for a long time did not get out, Until I returned to the basic definition of portal. In the portal definition, a very important feat

Liferay has a service builder mechanism that generates a set of interfaces and classes and configuration files for the persistence Layer and service layer, and when we write a service.xml and invoke ant target as Build-service, The framework uses the Servicebuilder class to parse the Service.xml file: For example, the service.xml we create is: When we run Build-service Target, the location of this service.xml file is used with the first paramete

Now let's make a summary: In fact, in order to have a better user experience, we have optimized from all aspects: The resource itself is cropped in size: For CSS,JS resources, we compress them with yui-compressor. For image resources, we use the Sprite tool bar multiple small pictures merged into large single pictures The cost of resources being downloaded from the server to the client is reduced: We have enabled the filtering of gzip filter on the server so that all the resources are comp

In Liferay, if we want to use our own JS library (such as the EXT-JS Library) instead of the default AUI library, you can follow these steps: (1) Place the library file We go to the $liferay_home/tomcat-7.0.23/webapps/root/html/js directory to build a directory called ExtJS, and then copy ext-all.js into. (2) Create the portal-ext.properties in the $liferay_home directory and then from the portal.properties in the Portal-impl.jar package Javascri

The Liferay SDK has the following directory structure: clients/is the directory for the client plug-in and provides an ant script to create the client plug-in dist/This directory holds the archive applications for deployment and release. For example, the last time we wrote 2 portlets, here are 2 corresponding applications: ext/is the directory of the Ext plugin and provides an ant script to create the EXT plug-in hooks/is the directory of the

DockBar is the most active element in Liferay, because almost all of the user's operations start from the DockBar, so we're here to analyze the DockBar in depth. Structure of the DockBar: DockBar is divided into 2 parts from the whole, part is the left The other part is the right So the final DockBar structure is (I omitted a lot of code):

After learning the ant build theme, Liferay theme, we easily ported the theme project to Maven. The following are the specific steps: Assume: Because we used the http://supercharles888.blog.51cto.com/609344/890525 development structure as shown in the article, let's assume we put the theme we're developing in D:\WalmartProject. First: Let's use the Maven Theme Wizard to create a theme: Once created, because we want our pom.xml to inherit Father

. Servicecomponentlocalserviceimpl.java is the core of the class, if you carefully study the code of this class will have other gains, here is only one example: you can see that this class actually supports the operation of upgrading the database, As long as the previous tablesql and the new TAblesql inconsistent, will perform the upgrade database operations, according to our thinking, we deployed two times the tables.sql is inconsistent, why not execute this code? Debugging finds that the Table
