Using <s:iterator> to populate a dynamic arraylist over multiple columns

由 女生的网名这么多〃 提交于 2019-12-31 03:49:26
问题 I am trying to populate an ArrayList over multiple table columns, this was originally done using Scriptlets on our old page but I know that the practice is frowned upon now. And I am having trouble translating it over using struts tags. I want the table to end up like this, Checkbox 1 Name 1 Checkbox 2 Name 2 Checkbox 3 Name 3 Checkbox 4 Name 4 etc.... This is the original scriptlet code: <% for (int j=0; j < getDocumentList().length; j++) { setPacket(j); setStringIndex(Integer.toString(j));

OGNL and wildcards working in tiles definitions with struts2-tiles-plugin?

由 与世无争的帅哥 提交于 2019-12-29 09:56:06
问题 I want Tiles to resolve ognl from the struts2 value stack. How to do this? Using tiles 2.2.2 (although if a later version such as 3 could be used that is fine) Here it mentions the new feature: http://tiles.apache.org/2.2/framework/whats-new.html Here it shows how to implement it: http://tiles.apache.org/2.2/framework/tutorial/advanced/el-support.html#OGNL_Support But I'm not certain how to go about that in my project. Does anyone have tiles3 working in their struts2 project? I remember

What is action context in Struts 2

由 怎甘沉沦 提交于 2019-12-25 04:24:13
问题 I don't understand this author: context, properties of the default or root object. ..based on a context I'm stuck at reading this portion of the tutorial: http://www.tutorialspoint.com/struts_2/struts_value_stack_ognl.htm "The OGNL is very similar to the JSP Expression Language. OGNL is based on the idea of having a root or default object within the context. The properties of the default or root object can be referenced using the markup notation, which is the pound symbol. As mentioned

Using jQuery Templates in Struts2

由 对着背影说爱祢 提交于 2019-12-24 20:22:48
问题 I am attempting to update a page using Struts2 (using jOWL to display an ontology). The original HTML page uses jQuery templates, having several lines such as: <h2 class="propertybox title" data-jowl="rdfs:label">${rdfs:label}</h2> <span class="alt">${?p}</span><span>: </span><span>${?t}</span> to display a variable determined in a jQuery script file. This works well enough as a .html file. However, the .jsp file thinks I am attempting to use Struts variables rather than a jQuery template. It

Thymeleaf入门到吃灰

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> Thymeleaf入门到吃灰 目录 回到顶部 Thymeleaf 官网部分翻译：反正就是各种好 Thymeleaf是用来开发Web和独立环境项目的服务器端的Java模版引擎 Spring官方支持的服务的渲染模板中，并不包含jsp。而是Thymeleaf和Freemarker等，而Thymeleaf与SpringMVC的视图技术，及SpringBoot的自动化配置集成非常完美，几乎没有任何成本，你只用关注Thymeleaf的语法即可。 Thymeleaf的特点 动静结合：Thymeleaf 在有网络和无网络的环境下皆可运行，即它可以让美工在浏览器查看页面的静态效果，也可以让程序员在服务器查看带数据的动态页面效果。这是由于它支持 html 原型，然后在 html 标签里增加额外的属性来达到模板+数据的展示方式。浏览器解释 html 时会忽略未定义的标签属性，所以 thymeleaf 的模板可以静态地运行；当有数据返回到页面时，Thymeleaf 标签会动态地替换掉静态内容，使页面动态显示。 开箱即用：它提供标准和spring标准两种方言，可以直接套用模板实现JSTL、 OGNL表达式效果，避免每天套模板、该jstl、改标签的困扰。同时开发人员也可以扩展和创建自定义的方言。 多方言支持：Thymeleaf
