src:源代码包 web.xml:和普通的Web工程的web.xml一样 build.xml:ant的构建文件，不需要修改继承自SDK portlet.xml:portlet定义的描述文件，这里定义了portlet的名称、初始化参数、模式类型、portlet相关信息、权限等；此文件中可以看到view-template对应的XXX.jsp，当我们在liferay里面添加portlet后，看到的页面内容就是XXX.jsp的内容 liferay-portlet.xml:定义Portlet默认可用的用户组、默认模板、是否支持多个实例等。这个文件中的 portlet-name 必须匹配 portlet.xml 中的 portlet- name。 liferay-display.xml:描述portlet所属类别 来源： oschina 链接： https://my.oschina.net/u/589482/blog/104936

由 浪尽此生 提交于 2019-11-27 10:54:43
问题 I'm new to ExtJS 4 and need some help understanding how the Ext.define works, please. In fact what I want to do is something similar to the portlets in the portal example, in my application I will need so many objects to add in my different tabs, so in order to organize my code and not have just one very big script, I want to define each component I need in a separate file and then call it in the main script when I need it (I will mainly use the examples so this is why I want to know how Ext

Passing array from .jsp to javascript function
