[opencms-dev] CmsJspActionElement not found

[Roland Wolf]

Hello,

after a smooth install of opencms 6 Alpha2 on Suse 9.1 I tried to build a 
customized navigation. The following JSP does not compile however:

  <%
com.opencms.flex.jsp.CmsJspActionElement cms = new 
com.opencms.flex.jsp.CmsJspActionElement(pageContext, request, response);
%>

The error message is:
package com.opencms.flex.jsp does not exist.

Is it necessary to install the sources of opencms in order to build a 
navigation?
Any help is appreciated.

Regards
Roland Wolf
