问题 I was wondering how to insert a <DIV> tag in between the pagination bar and the actual TABLE that starts the results display if I have the pagination bar at the top. If I just put the <DIV> tag right before my display:table, it also includes the pagination stuff inside the scroll bar. Also, I cannot figure out how to set the style to TBODY as it is a little bit confusing. I am not sure if you guys wrote this stuff but can you advise me if you have any idea how to achieve this. and my code is

问题 currently I'm using a JSP templating system which uses this example's lib ("/WEB-INF/tlds/template.tld"). I'm not even sure how it's called. Anyway it seems like it's not too developed, it makes problems with form POST method, I have no idea who made it (just found it) and I've heard about Apache's Struts & Tiles. I'm not even sure that Struts does what I'm talking about. Down to business: A page in my site has this JSP content, that utilizes the template: <%@ taglib uri="/WEB-INF/tlds

问题 I have an existing file in my HDD and I want rename this file. 回答1: Like this: new File(path).renameTo(new File(newPath)); 回答2: You may look at commons-io FileUtils.moveFile. That method tries File.renameTo, and if that fails, tries to copy&delete the file (e.g. when moving from one drive to another). If you use File.renameTo directly (which should suffice if you only want to rename a file in the same directory), make sure you evaluate the returned boolean value! 来源： https://stackoverflow.com

问题 I have a s:checkbox inside a html div. When the code is run, the checkbox is outside (both) the div and the divs seem to be empty and nonexistant. Why is this occuring and how can I fix it?

I set the background color to red so I can detect the div. <div id="outer"> <div id="inner"> <s:checkbox name="chBx" id"chBx" fieldValue="false" value="true" label="Check This" /> </div> </div> 回答1: Like described in this answer (that you

问题 I've a web application which uses framework like Struts and Hibernate. Currently I'm developing a scheduler for this application using Quartz. While coding I realized that the use of Hibernate session is not possible with the threads of Quartz. Anybody have a solution for using hibernate sessions from quartz job class? 回答1: One approach is to use a HibernateUtil class which builds the SessionFactory in a static initializer and makes it available via a public static getter. Your Quartz job can

问题 Is it possible to do an AJAX form submit without jQuery or IFrames (so just pure JavaScript)? I'm currently sending to a struts fileUploadAction that works. Would the action's code still work with the asynchronous submit, or are there additions required to pick up the async form submit? I am using struts 1.x and current my form is: <html:form action="fileUploadAction" method="post" enctype="multipart/form-data"> ...form elements... <html:file property="theFile" /> ...other elements... </html

问题 I am developing a Java EE web application using Struts. The problem is with Internet Explorer caching. If an user logs out he can access some pages because they are cached and no request is made. If I hit refresh it works fine. Also if an user goes to login page again it won't redirect him because that page is also cached. Two solutions come to my mind: Writing an Interceptor (servlet filter like) to add to response header no-cache etc. Or or put <meta> tags at each page. Which one should I

问题 Methods invoked: 1. Struts Action 2. Service class method (annotated by @Transactional) 3. Xfire webservice call Everything including struts (DelegatingActionProxy) and transactions is configured with Spring. Persistence is done with JPA/Hibernate.
