[FIXED] Getting Error While Using request.getRealPath("/") in JSP Page

Issue

I am trying to use the request.getRealPath("/") to get the Path for the resource files in JSP page. But i get below error when i try to run the page in Eclipse.

<jsp:setProperty name="LIILLog" property="configPath" value="<%=request.getRealPath("/")%>"/>

The error which i get is as below:

May 31, 2020 7:58:03 PM org.apache.catalina.core.StandardWrapperValve invoke
SEVERE: Servlet.service() for servlet [jsp] in context with path [/LHC] threw exception [/lhc_admin_login.jsp (line: [28], column: [64]) Attribute value [request.getRealPath("/")] is quoted with ["] which must be escaped when used within the value] with root cause

I am using a Maven Project in Eclipse and Tomcat 8.5 server.

Solution

Your problem is exactly what the error says, you need to escape the quotes or use single quotes:

Do this:

value='<%=request.getRealPath("/")%>'

or (don't) do this (it is ugly):

value="<%=request.getRealPath(\"/\")%>"
