Assign variable in JSP file to Java String

I have this variable ${baseURL} which is set like so

<c:set var="baseURL" value="${fn:replace(pageContext.request.requestURL, 
  pageContext.request.requestURI, pageContext.request.contextPath)}" />

I need to assign it to a Java String or pass it into a Java function within the same jsp file.

Solution

  • You can assign a JSTL variable to a JAVA variable by getting its value using pageContext.getAttribute() method as follow:

    <% Strig s = (String)pageContext.getAttribute("baseURL"); %>
