[opencms-dev] using cms:include from a jsp

[Mario Jäger]

Hi,

When an user requests the URI of a xml content resource in OpenCms, then 
the "template-elements" property is read from the requested resource. If 
it contains a path to a JSP, this JSP is called. The JSP reads the XML 
content from the requested resource and renders it’s output from it. 
This is not the behaviour for a xml content you include in a jsp with 
<cms:include>. For example, the "template-elements" property of the xml 
content is not used then. <cms:include> dynamically includes JSP 
elements. Usually, <cms:include> is used with a "file" (or "property") 
attribute to specify the resource providing the included jsp element: 
<cms:include file="..." element="..." />. The "Null Pointer Exception" 
(you wrote in your first mail of) you get, because you used the 
<cms:include> for the xml content without the "element" attribute (you 
should use the <cms:content...> tags, not the <cms:include> tag to 
access the XML content elements). It seems, that the xml content we 
speak of, only shall be a sub element in the page you want to render. 
Only, if I would know the content of your module and some more details 
to the target you want to reach, I could say, if it could be improved. 
But, you say, that generally it works...

Kind Regards,
Mario.
