JSTL if-statement inside HTML-attribute
CssJspJstlJsp TagsCss Problem Overview
is it possible to do something like this in JSTL:
<div class="firstclass<c:if test='true'> someclass</c:if>">
<p>some other stuff...</p>
</div>
Is there any way to get this to work, or is there a better way to add a class by looking at a JSTL-if-statement?

It's also possible to use an EL expression directly like this:
<div class="${booleanExpr ? 'cssClass' : 'otherCssClass'}">
</div>
Solution 2 - Css
<c:if test='true'>
<c:set value="someclass" var="cssClass"></c:set>
</c:if>
<div class="${cssClass}">
<p>some other stuff...</p>
</div>

That works for me!
<div id="loginById" style="height:<% out.print(instanceClass.booleanMethod()? "250px": "150px");%>">
