问题 I am following this tutorial to build my first Struts2 example. My project name (and war file also) is HelloWorld and whenever I try to access http://localhost:8080/HelloWorld/index.jsp I get The requested resource is not available. I have my war file in tomcat webapps directory and tomcat is running fine. Where am I going wrong? 回答1: That tutorial is OLD. It still uses org.apache.struts2.dispatcher.FilterDispatcher , that is a deprecated filter since Struts 2.1.8. You need to use the new

问题 I have this function in Struts 1: /* * (non-Javadoc) * * @see org.apache.struts.taglib.bean.WriteTag#doStartTag() */ public int doStartTag() throws JspException { Carac carac = (Carac) TagUtils.getInstance().lookup(pageContext, name, property, scope); // Code here return SKIP_BODY; } and I am trying to create the same tag in Struts 2 but don't know what's the purpose of this: TagUtils.getInstance().lookup() 回答1: I found a solution to get my object from the view to the tag in struts 2 : my tag

问题 In one of my Struts action I've got the following code in a method: ... List<Object> retrievedListOfObjects = c.getListOfObjects(); return mapping.findForward("view"); } fw_view leads to a new Struts action with another Struts form. Let's say this form has got among others the following field List<Object> listOfObjects; I now want to pass the retrievedListOfObjects from within the first Struts action to the form of the following Struts action. Is this possible without storing it in the

问题 I started out with a problem concerning a list/dropdown list on one of my jsps but now I realized my main problem is concerning the data input between actions/pages. Old question I am trying to navigate from one page displaying one specific object to a nother page displaying an attachedObject (to the first one) and then navigate back to the first object page. The last step is the one I have problems with. The whole workflow is: first page: display a list of objects, select one and then go to

问题 I have a application in which I used struts1.2 and ejb2.1 now I want to add spring security using LDAP server in it. How to integrate Spring Security with struts1.2? 回答1: Integration shouldn't be different than any other web app. You need the spring-security dependencies either the jars or the maven dependencies. I'll post the maven dependencies, if you don't use maven you can look the jars up from here: mvn browser <properties> <spring.version>3.0.1.RELEASE</spring.version> </properties>

问题 Is it possible to convert my <html:text... in HTML5 format (type=email, number, etc...) Is it possible with Struts tags ? 回答1: You'd need to take the existing tag library and convert then to output the new tags. If you do, you could file it as a patch I don't know of any efforts under way to do this for Struts 1, which is likely to be EOLed soon anyway. 来源： https://stackoverflow.com/questions/7497326/use-html5-input-with-struts

问题 I try to run a web application on oracle linux, tomcat 7 and jdk1.7 and I get an exception on first page load after tomcat restart. The exception occurs only at first application pageload. Application is developed on jdk1.6 and on a server is installed jdk1.4-compact and jdk1.7 but I entered jdk1.7 path to JAVA_HOME and JRE_HOME in tomcat/bin/setclasspath.sh file.

问题 In Struts2, a controller dispatches a Request to an Action and the Action passes it to back-end logic, which could be regarded as a very big "model", to process the request and JSP represents Views. How to define the Action in Struts2 ? Definitely it's not View... is it the Controller or Model? 回答1: Struts actions are controllers in the sense of the MVC pattern. I think the discussion of the value stack and ActionContext , as well as getter methods in action classes confuses the issue. In

问题 I am interested in building a vehicle tracking system using GPRS. However, I have some questions for anyone who has done this before: Is GPRS the best technology to use? Any problems people are aware of? I am planning on using Java/Java EE - is there any better technologies? If someone has built this before - do you have some examples of what to see for system requirements? What are some good web resources you've found working on this? Is there a step-by-step guide anywhere to getting started

问题 So, I have this code: logic:iterate name="nameForm" property="name" id="nameId" indexId="index" bean:write name="nameId" property="field1"/ bean:write name="nameId" property="field2"/ This works great because I'm receiving a "table of objects" so I can do the iterate without issues. Now, on another page I need to do the same but the issue is I am not receiving a "table of objects" but an object itself. I tried it nonetheless and - as expected - got the error: Cannot create iterator for this
