Question

I have a Struts 2 application using the JSTL/Struts2/DisplayTag tag libraries in my JSP. Is there a way to access the value of a Map in a JSP given the key?

// Action code
Map<String,String> map = new HashMap<String,String>();

mapOnValueStack = map;

//add key/value pairs

fieldKeyOnValueStack = "1";//sets key

….

<%-- JSP code --%>

<s:property value="%{mapOnValueStack.get(fieldKeyOnValueStack)}" />

Essentially I want to do map access within the JSP. Is this possible?

Thanks!

Did you try this :

<s:property value="%{mapOnValueStack.['fieldKeyOnValueStack']}" />
