问题 I am trying to integrate Spring into a JSF application. In faces-config.xml , I have included this: <application> <el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver> <view-handler>com.sun.facelets.FaceletViewHandler</view-handler> </application> but it shows a weird warning which I can't get rid of: Class org.springframework.web.jsf.el.SpringBeanFacesELResolver must extend the type javax.el.ELResolver Any ideas? 回答1: From the spring documentation, you will see

问题 I have a JSP page that contains a scriplet where I instantiate an object. I would like to pass that object to the JSP tag without using any cache. For example I would like to accomplish this: <%@ taglib prefix="wf" uri="JspCustomTag" %> <% Object myObject = new Object(); %> <wf:my-tag obj=myObject /> I'm trying to avoid directly interacting with any of the caches (page, session, servletcontext), I would rather have my tag handle that. 回答1: A slightly different question that I looked for here:

问题 I want to set a jsp parameter to an attribute value which may contain special symbols, then use a form GET submit to pass the parameter to a servlet controller. For example, the parameter is: <input type="hidden" name="searchTerms" value="${sessionScope.combTerms}"></input> I noticed if sessionScope.combTerms contains double quotes, eg. location:"LOC1" , the controller will only receive the value of searchTerms to be location: in which the LOC1" disappeared. What should I do to make sure

The function is invoked by ${person.currentlocation} in the jsp file. type Exception report message javax.el.ELException: Error reading 'currentlocation' on type **.person.Person description The server encountered an internal error that prevented it from fulfilling this request. exception org.apache.jasper.JasperException: javax.el.ELException: Error reading

问题 Trying to figure out this issue for a long time... I am setting a variable with a value from an Object. <s:set name="bodyText" value='First Name "myObject.name"'/> and trying to print it in the following ways.. None of these works. "${bodyText}" "<s:property value="#bodyText" />" "${#bodyText}" "%{bodyText}" "%{#bodyText}" Not sure the problem is with I tried the following as well: <s:set name="bodyText" value='First Name "${myObject.name}"'/> But it did not work. 回答1: The value attribute

问题 I'm serious tired of getters/setters clogging my code, when I don't need to control access to the internal state of an object. The only real reason I have to still generate getters/setters is because JSF2.0 / EL 2.2 works by locating methods, not fields: ${myBean.fieldName} . where fieldName refers to the function getFieldName() . Would it be possible to extend an EL Resolver to just return the public field value unless a getter was found? EDIT: I hope this helps someone else. Notice how I

问题 I have a javascript file, where I have collected login- and other user profile ajax calls that needs to be available on all of the pages in my web application. For all of my ajax calls, I need the context path of the webapp to get the correct URL. A baseUrl-variable can be defined by var baseUrl = "${pageContext.request.contextPath}"; . I am experiencing a puzzling error though. If i try to initialize the baseUrl variable inside my login.js -file, it does not work. It is simply set to the

问题 I want to call fn:replace inside EL inside c:out to replace quote caracters. The following does not work <c:out value="${fn:replace(userName,'"','\\"')}"/> because XML parser stops at first double quote and sees no c:cout tag termination (JSP compilation stage error). The following <c:out value="${fn:replace(userName,'"','\\"')}"/> does not work, probably because replace function does not see actual quote character. 回答1: Parameterize them with <c:set> . <c:set var="search" value='"' /> <c:set

问题 This question may be more of the type "conceptual" or "I don't understand JSF". My scenario: I have a JSF Page ( index.xhtml ) where I use a p:accordionPanel (but I don't think it matters what component it is). What I want to do is to set the activeIndexes of it. <p:accordionPanel multiple="true" activeIndex="#{myController.getActiveIndexesForSections('whatever')}"> // bla bla... </p:accordionPanel> And the (simplified) method in the backing bean: public String getActiveIndexesForSections
