Vedr.: [opencms-dev] first steps in JSP - error message?
Hi Everyone,
I modified the example given in Alkacon Documentation|OpenCms Scriptlet
Docs|Documentation for the getNavigation() method for the purpose of
displaying only folders.
I marked the line I added with (***) in the following code:
+++ code start +++
<%@ page import="java.util.*" %><%
// Create a JSP action element
com.opencms.flex.jsp.CmsJspActionElement cms = new
com.opencms.flex.jsp.CmsJspActionElement(pageContext, request, response);
// Get a simple navigation of all pages / subfolders in the current folder
ArrayList list = cms.getNavigation().getNavigationForFolder();
Iterator i = list.iterator();
out.println("<h3>A simple sample navigation</h3>");
out.println("<p>Cache properties: <b>" + cms.property("cache","this") +
"</b></p><ul>");
while (i.hasNext()) {
com.opencms.flex.jsp.CmsJspNavElement ne =
(com.opencms.flex.jsp.CmsJspNavElement)i.next();
(***) if (ne.IsFolderLink()) {
out.println("<li><a href=\"" + cms.link(ne.getResourceName()) +
"\">");
out.println(ne.getTitle() + "</a></li>");
}
}
out.println("</ul>");
%>
+++ code end +++
Then I get an error-message (see below).
What can I do?
Tank you,
Michael :-))
+++ error-msg start +++
