liferay portlet

Last time, in this blog http://supercharles888.blog.51cto.com/609344/897825, We're talking about how to fix the multiple dependencies on slf4j that arise when using Maven's Service-builder, and now we're going to show you how to customize the plugin. This allows you to avoid this error by using our own plug-ins instead of the default Liferay-maven-plugin in your project: Authoring of Plug-ins: Specific writing details will not say, anyway, is to use

Introduction: We all know that we can use sessions to store attributes, but Liferay PortletSession is somewhat special. It can use different scopes to store different attributes. Our sample code is as follows: 650) this. width = 650; "src =" http://www.bkjia.com/uploads/allimg/131228/15061KS6-0.png "title =" 1.png" alt = "153666521.png"/> Here we will study the details of PortletSession, for example, how to store the attributes on different scopes. D

Today, my colleagues need to switch to maven in the Liferay service builder, because Maven 6.1 is already in the archetype, so I thought it was a simple question, and I know it's been hard for me 3 hours. The previous steps are the same, creating a service-builder archetype, as shown in the following figure: Then, when you run the command Liferay:build-service, the following problems always occur: Info: Global Lib directory/c:/users/asus/.m2/rep

Original article: http://www.ja-sig.org/wiki/display/UPC/Portlet+Development+Framework I spent a few weeks researching different approaches and frameworks to developing portlets. the basis for this research was to find a good methodology to developing portlets for uportal 3.0. A specific desire was to try to find a way to reuse as much functionality as possible using SS different portlets. Portlets are different from uportal channels. uportal channels

Portlet Filters and Portlet windows In the 1th part of this series, we briefly review the JSR-2.0 portlet and introduce the new features of the JSR 286 portlet in detail, with parts 2nd and 3rd going through the development and deployment of portlets on the Apache Pluto platform Application to introduce to readers how

JSR 168 Portlet Standard Java Standardization Request 168 (JSR 168) defines a Portlet specification, including contracts between the Portlet container and the Portlet. JSR 168 is defined by Java Community process (JCP. JSR 168 is jointly led by IBM and sun and has a large trusted CT group to help create the final versi

Today, I opened two liferay-portlet environments on the E drive. They were all downloaded and bound. A bundles (with tomcat in it) + plugins-sdk (with portlet-related configurations ). Every time there is a ready-made one, the Manager will give it to us and we can use it directly. Today we don't know why we can't. Once we deploy A

In Liferay the request is divided into renderrequest and actionrequest the two kinds of requests, Portletrequest subclass has three 1renderRequest, 2eventrequest3clientdatarequest. Is there no actionrequest? , not the Actionrequest inherited is clientdatarequest this interface.The scope of Actionrequest is the portlet during the action processing phase, at which point the

1 native Portlet development This is the simplest and most essential development method. You can develop a Portlet directly based on the Interface defined in the Portlet specification. The advantage is that the bottom layer is relatively flexible, and the disadvantage is that everything should be done by yourself. It is just like using Servlet-based development w

Objective:Develop a portlet application that conforms to the JSR-168 standard and deploys it to the Jetspeed2. Familiarize yourself with the development process of portlet applications and understand JETSPEED2 support for portlet applications. Background information:JSR-168 Standard: The Portlet Specification 1.0 final

After the first login, liferay generates a default private homepage layout for the user. In earlier versions of liferay, you can configure the default group layout on the system administrator management interface. However, this function is not available in version 4.1, so by default, newly registered users first see the same private place content after login, these contents are provided by

When clicking on the DockBar on the Add->more ... , he entered the layout_configuration: This is also a portlet (a special portlet in the Liferay kernel), portlet_id 87, see Liferay-portlet.xml: The page corresponding to this portlet is in/html/

1. Overview Full-dynamic Portlet, as its name implies, means that all the displayed content is dynamic, including the display style and data. The display style is set through the HTML template, and the data can have multiple sources: common ESB message flows are provided, constructed by handler, or configured through static data in portal management.2. Data Template Configuration A full dynamic template is an HTML template that defines the data displa

Summary JSR-168 is a collection of Java APIs that are appropriate for portlet developers. There are many reasons to design a JSR-168 portlet that conforms to specifications. Portability is an obvious benefit. Code written according to specifications is easier to move between portal servers. Most Java-based portal servers support JSR-168 portlets. Another advantage is that it is easier to unite. It is easier

There are portlet.xml in the portlet, and we can all see the following code for security settings: .. In fact, a lot of people including me have a question, is that some portlets even if not set I went through the next Liferay-in-action book, and in the P154 corresponding to the 4.5 section "Programmitic Security," you can see that only when you use programmatic access control in your code (such as I

We already know a lot of kinds of processing file upload code, more typical such as Apache famous FileUpload, of course, Liferay for us have considered, we can use Liferay upload files with the API to deal with file upload problem, This core interface is the Com.liferay.portal.kernel.upload.UploadPortletRequest interface. For the simplest example, we're going to upload a file into the
