[opencms-dev]Publishing jsp content that is part of an XML te mplate JSP

[Rod Thorburn]

Thanks Mark - that worked fine. However, I've only managed to get the
desired output in "off-line" mode. In other words, it would appear that the
jsp element is not being published, or is inaccessable to the other page
elements.

Using Alexander Kandzior's example from [opencms-dev]flex: JSP and
templates? August 30, I inserted  a reference to a jsp element in a page
template which resides in /content/templates/, as below:
---------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<XMLTEMPLATE>
 
    <ELEMENTDEF name="header">
        <CLASS>com.opencms.template.CmsXmlTemplate</CLASS>
        <TEMPLATE>/content/elements/static_header</TEMPLATE>
    </ELEMENTDEF>
    
    <ELEMENTDEF name="frametemplate">
        <CLASS>com.opencms.template.CmsXmlTemplate</CLASS>
        <TEMPLATE>/content/frametemplates/main_frame_template</TEMPLATE>
    </ELEMENTDEF> 
    
    <ELEMENTDEF name="bodycontent">
        <CLASS>com.opencms.template.CmsXmlTemplate</CLASS>
        <TEMPLATE>/content/elements/body_with_right_channel</TEMPLATE>
    </ELEMENTDEF>

    <ELEMENTDEF name="contenttemplate">
        <CLASS>com.opencms.template.CmsXmlTemplate</CLASS>
 
<TEMPLATE>/content/contenttemplates/Article_Content_Template</TEMPLATE>
    </ELEMENTDEF>
     
    <elementdef name="document_body">
    	<CLASS>com.opencms.flex.CmsJspTemplate</CLASS>
        <TEMPLATE>/content/elements/newsHeadlines.jsp</TEMPLATE>
    </elementdef>

	<TEMPLATE>
		<ELEMENT name="frametemplate"/>
	</TEMPLATE>
	
</XMLTEMPLATE>
----------------------------------------------------------------------------
-
The jsp in question (newsHeadlines.jsp) resides in /content/elements/ .It's
export property=false, cache=always and stream=true.
However, when I view the page that this template produces in "online" mode,
all page elements are rendered except the "document_body" element, for which
"[document_body] ??? " is displayed.
The above is executed in opencms5_beta. Combinations of export=true/false
seem to make no difference, though I suspect that the problem rests there
somehow.
Any advice would be greatly appreciated.
Regards, Rod

Hi Rod,

You could try something like:

com.opencms.flex.cache.CmsFlexRequest req
= (com.opencms.flex.cache.CmsFlexRequest)request;
com.opencms.file.CmsObject cms = req.getCmsObject();
String docRole  = cms.readProperty(cRes.getAbsolutePath(),"Role");

Here we have created another property called "Role" which contains string
info.  You can equally well use this for default properties, such as
"Title" and "Description".

Regards,
Mark

I am exploring the jsp functionality in opencms5_beta to build a dynamic
directory listing (based on the flex-examples that came with the
distribution). The following code snippet returns the Description, Title
and NavText elements for each .html file in the directory /news/articles/


      // Link substitutor to make sure static export works
      com.opencms.util.LinkSubstitution subst = new
      com.opencms.util.LinkSubstitution();
      // Collect the objects required to access the OpenCms VFS from the
      request
      com.opencms.flex.cache.CmsFlexRequest req
      = (com.opencms.flex.cache.CmsFlexRequest)request;
      com.opencms.file.CmsObject cms = req.getCmsObject();
      com.opencms.file.CmsFile file = req.getCmsFile();

      // Get the folder name
      String foldername = "/news/articles/";

      // Get a list of all pages / subfolders in the folder (sorted by
      NavPos property)
      java.util.ArrayList list =
      CmsJspNavElement.getNavigationForFolder(cms, foldername);
      java.util.Iterator i = list.iterator();
      while (i.hasNext())
      {
          CmsJspNavElement ne = (CmsJspNavElement)i.next();
          %><p>
              <%=ne.getDescription() != null ? ne.getDescription() : ""
      %><br>
              <%=ne.getTitle() != null ? ne.getTitle() : "" %><br>
              <a href="<%=subst.getLinkSubstitution(cms, ne.getResourceName
      ())%>"><%=ne.getNavText() != null ? ne.getNavText() : "" %
      ></a>
          </p><%
      }





What I also want to do is extract or use other Property values for a given
.html file, that are not defined by CmsJspNavElement.java . For example , I
may have created a Property called "Date", or I might want to select only
certain .html files by a value in the "Key Words" Property.


The temtation is to call the method getProperty() , but this method is not
defined in the CmsJspNavElement class (as far as I can determine it is only
available in CmsJspTagUser.java) .


Does anyone know of a way of accessing additional file Properties in the
above context without writing additional code in the appropriate classes?
