We are trying to move our Java web application from a Tomcat 5.5 server to a more modern Tomcat 6.0.24 one, but we are having some problems with JSP EL. The expressions placed within XML tag files are not recognized by the server, that simply renders them as text (just as in the following example). Any ideas why? <object id="${id}" ...
How can the JSF implicit objects be access via expression language? For example, if I wanted to determine what roles the current principal is associated with, how could I do this? ...
It's tedious and ugly to write things like: <input type="button" value="<fmt:message key="submitKey" />" /> And in case you want to nest the message tag in another tag's attribute it becomes even worse. Is there any shorthand for that. For example (like in JSF): <h:commandButton value="#{msg.shareKey}" /> (spring-mvc-only solution...

So we all know that #{someBean.value} will try and get the content of some property on 'someBean' called 'value'. It will look for getValue(). However, what if this property is boolean? It will look for isValue(). What it won't look for is hasValue(). This got me thinking, what exactly does it do? this: http://download.oracle.com/docs/...
I have a generic buttons jsp: <wow:button id="addButton" iconClass="add16 icon16x16" action="#{managedbean.addNew}" type="submit" immediate="true" value="#{lblMsg.label_add }" /> <wow:button id="deleteButton" iconClass="iconCancel" action="#{managedbean.delete}" type="submit" value="#{lbl...
Hi all, when I use <c:out value="${track}"> in a jsp, where should the attribute track be located in (servletContext, httpSession and request)? I tried to have a controller to set the attribute track to the httpSession, but then ${track} doesn't give me anything in the .jsp. On the other hand, if I set it to the servletContext, ${track}...

For example, the parameter is: <input type="hidden" name="searchTerms" value="${sessionScope.combTerms}"></input> I noticed if sessionScope.combTerms contains double qu...

I could successfully access simple ResourceBundle keys like this: alert("#{bundle.message_email_sent}"); Unfortunately, my convention for keys ...
I'm trying to write a custom JSPX tag that reads the value of a given bean property from each object in a given list, with the name of that property passed to the tag as a JSP attribute. The tag would look something like this: <jsp:root xmlns:c="http://java.sun.com/jsp/jstl/core" xmlns:jsp="http://java.sun.com/JSP/Page" ...
I have a JSF2 application that renders a large table with complex content. Unfortunately, each request takes up to 6 seconds to process. Using simple debug output inside a phase listener, I could see that the performance loss distributes evenly over all phases that process the component tree. So I started up a profiler to see what's goin...
The textual versions may improve readability for non-programmers, but otherwise I can't imagine any differentiators. ...
How can I set precision for such EL result? <h:outputText value="#{businessPlanPreviewBean.plan.a1 != 0 ? businessPlanPreviewBean.plan.a2/businessPlanPreviewBean.plan.a3 : 0 } " > </h:outputText> I tried <f:convertNumber maxFractionDigits="2" /> but no luck... <f:convertNumber pattern="#,##" /> - the same thing Mojarra JSF implem...

Hello everyone, I would like to ask you some help in clarifying a few issues. But, before anything, some code is inbound first - it's a really simple login example I've constructed. Container is Tomcat 5.5.27. Let's assume correct username and pass combination is entered; questions are at the bottom. LoginPage.jsp (entrypoint - view)...
