taglib

问题 So I'm trying to import two taglibs: <%@ taglib uri="MyCustomTagLib" prefix="myLib" %> <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %> However, I can only use ONE of them or else I get an error (I shortened it, hope that's ok): WARNING: ApplicationDispatcher[/CSE336_A5] PWC1231: Servlet.service() for servlet jsp threw exception java.lang.NullPointerException at org.apache.jasper.compiler.TagLibraryInfoImpl.toString(TagLibraryInfoImpl.java:129) at java.lang.String.valueOf

问题 I'm writing a Spring 3 MVC based web app, using JSPs for my view layer. I'm struggling on a particular area where I'm trying to report BindingResult errors for a particular Model object in a JSP. This is probably best explained with the appropriate code: This is my Spring Controller method: @RequestMapping(value = "/**", method = RequestMethod.GET) public ModelAndView get(@ModelAttribute("xApiRequest") @Valid final XAPIRequest xApiRequest, final BindingResult xapiBindingResult, final

问题 I try to use JSF 2.1 within JSP 2.0. When I add this <%@taglib uri="http://java.sun.com/jsf/html" prefix="h" %> I get the following error: Unable to read TLD "META-INF/html_basic.tld" from JAR file "file:/home/fadhel/.m2/repository/javax/javaee-web-api/6.0/javaee-web-api-6.0.jar": org.apache.jasper.JasperException: PWC6169: Failed to load or instantiate TagLibraryValidator class: com.sun.faces.taglib.html_basic.HtmlBasicValidator. Can someone tell what I can do to use JSF 2.1 and JSP 2.0 with

问题 One of the things I liked about freemarker is that you can quickly create new macros that encapsulate complex html to make the pages smaller and more concise. Do I have to make tag libraries to do the same thing in grails, or is there a really light-weight syntax for achieving the same thing? 回答1: There is a <g:render> tag, which may match your needs. It's documented here. 来源： https://stackoverflow.com/questions/2903353/is-there-a-way-to-do-gsp-partials-rather-than-tag-libraries

问题 Currently I have taglibs set up and working correctly using the following tag at the top of my JSP pages: <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> In Maven I have the dependencies: <dependency> <groupId>cglib</groupId> <artifactId>cglib</artifactId> <version>2.2.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api<

问题 I have a third party precompiled library (.lib+.dll) that I use in my Qt application. In a regular (qmake) QtCreator project I have the following lines in my .pro file: LIBS += -L$$PWD/lib/release -ltag INCLUDEPATH += include/taglib There is also an option in Projects tab -> Run -> "Add build library search path to PATH" which is by default ON. It ensures that LIBS path gets added to system PATH, so the dll can be found. However, I can't find an equivalent in QBS. I have the following qbs

问题 I have TagLib, Service and TestCase as follows How to mock a service in a taglib to get expected result from service TagLib: class SampleTagLib { static namespace = "sample" def baseService def writeName = { attrs, body -> def result = baseService.findAttributeValue(attrs.something) if(result) out << body() } } Service: class BaseService { def findAttributeValue(arg1) { return false } } TagLibUnitTestCase: import spock.lang.* import grails.plugin.spock.* import org.junit.* import grails.test

问题 I have defined a taglib like this: class FooTagLib { static namespace = "foo" def bar = { attrs, body -> out << render(template: "/taglib/foo/bar", model: [body: body]) } } The body closure takes two parameters, baz and qux, why can't I do this in my /taglib/foo/_bar.gsp: ${body(baz: 'Hello', qux: 'world!')} ? This is how I use this tag in my gsp views: <foo:bar> ${baz} ${qux} </foo:bar It prints the content of the body, but the parameters are all null : null null Is this a bug or is there

问题 So I used to configure my taglib like that: <jsp-config> <taglib> <taglib-uri>myTags</taglib-uri> <taglib-location>/WEB-INF/lib/mylib-2.0.1.jar</taglib-location> </taglib> </jsp-config> But now mylib-2.0.1.jar is a maven dependency, so of course it is NOT on /WEB-INF/lib. How do I do to configure my taglib so I can do that in my JSPs: <%@ taglib uri="myTags" prefix="mt" %> EDIT1: To clafiry, the taglib.tld is inside the META-INF inside the jar so you can access the tld by referencing the jar

问题 Similar problems are invoked in many posts in this forum; but no one has a solution that specific one, I thank you for helping me in this : I'm using spring to develop a web application, I don't know what I should put in the path of the form:checkbox tag which inside the c:foreach one, here is my code : <c:forEach items="${persons}" var="person" varStatus="i"> <tr> <td><c:out value="${person.firstName}" /></td> <td><c:out value="${person.lastName}" /></td> <td><form:checkbox path="person
