taglib

Can I access the expression string of a ValueExpression passed as attribute value to my taglib component? My goal is to programmatically derive missing attribute values from it. In this case I'm trying to avoid having to repeat an attribute as a literal. now: <a:columnText title="name" value="#{entity.name}" sortBy="entity.name" /> desired: <a:columnText title="name" value="#{entity.name}" /> -taglib.xml <tag> <tag-name>columnText</tag-name> <source>column-text.xhtml</source> <attribute> <name>value</name> <required>true</required> </attribute> <attribute> <name>title</name> <required>false<

I'm attempting to use JSPX (pure XML syntax for JSP) and running into what seems like it should work, but doesn't. I'm importing taglibs using namespace declarations in the jsp:root element, then using these later on for elements as well as EL functions: <jsp:root version="2.0" xmlns:jsp="http://java.sun.com/JSP/ xmlns:c="urn:jsptld:/WEB-INF/tld/c.tld" xmlns:fn="urn:jsptld:/WEB-INF/tld/fn.tld"> ... <c:if test="${fn:length(list) > 0"> ... </c:if> ... </jsp:root> I get an exception saying "The attribute prefix fn does not correspond to any imported tag library". Other pages work fine, but this

I'm still new to Guice and haven't used any DI frameworks before. After reading the official wiki and many other documents I'm still unable to wrap my head around it completely. In my particular case I want to write a EL taglib function that uses some other (to-be-injected) class. As all taglib functions have to be declared as static, I can't just @Inject my dependency via constructor or setter. I thought of using the requestStaticInjection() method described in http://code.google.com/p/google-guice/wiki/Injections#Static_Injections but I unable to get it to work and haven't been able to find

I have a custom JSP tag which is using a parameter which is an enum. This approach is a consequence of using other classes which need this enumeration. The point is I have no clue how to assign an enum value in the EL: <mytaglib:mytag enumParam="${now what do I type here?}" /> The only workaround which I found so far was to make the enumParam an Integer and convert it to desired values: <mytaglib:mytag enumParam="3" /> I believe there must be a better way to do it. Please help. devpg EL allows the use of Enums! There are three ways to set a tag attribute value using either an rvalue or lvalue

My html is built without using the spring taglib and now I'd like to bind the parameters of the form to a object in my controller. Currently my form looks like this <form> <input type="text" name="frAccUserMgmt.userName"/> <input type="password" name="frAccUserMgmt.userPwd"/> </form> The relevant part of my object is Class FrAccUserMgmt { private String userName; private Strint userPwd; // getter and setter } My controller is @RequestMapping("login") Public ModelAndView doLogin(FrAccUserMgmt frAccUserMgmt) { //code } How do I go about binding it. Currently the binding doesn't happen. I just

I've been struggling with this issue for a little while now. Found several posts about it but none solved my problem. It will probably have something to do with the fact that a SecurityContext is boud to a specific Thread but even then I do not know how to solve it: Consider following code to retrieve the user that was logged in: SecurityContextHolder.getContext().getAuthentication().getPrincipal() Running this code in a controller would return (correctly) the user logged in. Running this code from a taglib or jsp throws NPE (authentication = null). Also the spring tag does not function
