Question

I’m trying to access the servlet path from a tag file like so;

<%@tag description="put the tag description here" pageEncoding="UTF-8"%>
<%=pageContext.getServletContext().getRealPath("/")%>

However it complains it cannot find the symbol;
string:///xxxxx:89: cannot find symbol
symbol : variable pageContext
location: class org.apache.jsp.tag.web.xxxx

any suggestions on how to access that value in the tag file?

Answer 1

Since the expression appears within a tag file, pageContext is not a valid implicit object. As you’ve noted, application is valid, so is jspContext (an instance of javax.servlet.jsp.JspContext). On a related note, it is possible that getRealPath will return null…
