Struts2 tags in divs appear empty

由 落花浮王杯 提交于 2019-12-02 11:08:27
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? When I place random text inside either div, the div contains 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> Andrea Ligios Like described in this answer (that you should consider upvoting too), Struts2 generates (or not) a certain kind of HTML when rendering

How to rename an existing file

由 假装没事ソ 提交于 2019-12-02 10:12:55
I have an existing file in my HDD and I want rename this file. Like this: new File(path).renameTo(new File(newPath)); 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/questions/2804105/how-to-rename-an-existing-file

Cannot find the tag library descriptor for /WEB-INF/struts-html.tld in Struts

I am new to the Struts framework and while developing a simple Struts 2 application I'm getting the following error: Cannot find the tag library descriptor for /WEB-INF/struts-html.tld How do I fix this error? Andrea Ligios struts-html.tld is a TLD for Struts 1 tags. Struts 2 uses a single TLD, struts-tags.tld , and it's in the struts2-core-2.x.x.jar . You can declare it as follows: <%@ taglib prefix="s" uri="/struts-tags" %> There are other TLDs like struts-dojo-tags (deprecated in 2.1), struts-jquery-tags , etc... but start with the main one, take a tour of Struts2 and then eventually try to

why does struts reset my form after failed validation?

由 不想你离开。 提交于 2019-12-02 05:30:47
I am using the validation framework with Struts 1.1.When validation fails, the entire form is reset. After much time scouring the net, I have gathered: When a new request is received, the form object is created if it does not exist in the current scope (request or session). Reset is called() Form values are populated from the bean properties. Validation starts if enabled If validation fails, ActionErrors are returned and the request is directed to the URI given by the input attribute of the action tag in my struts-config.xml. That's where I have the problem. If validation fails, and I set the
