      org.opencms.jsp.CmsJspTagProperty

All Implemented Interfaces:

java.io.Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class CmsJspTagProperty
extends javax.servlet.jsp.tagext.TagSupport

Provides access to the properties of a resource in the OpenCms VFS .

Of particular importance is the setting of the file attribute, which can take the following values.

This attribute allows you to specify where to search for the property.
The following values are supported:

uri (default)

Look up the property on the file with the uri requested by the user.

search.uri or search

Look up the property by also checking all parent folders for the property, starting with the file with uri requested by the user and going "upward" if the property was not found there.

element.uri

Look up the property on the currently processed sub - element. This is useful in templates or other pages that consist of many elements.

search.element.uri

Look up the property by also checking all parent folders for the property, starting with the file with the currently processed sub - element and going "upward" if the property was not found there.

sitemap

reads from the current sitemap entry

search.sitemap

Look up the property by also checking all parent sitemap entries for the property, starting with the current sitemap entry and going "upward" if the property was not found there.

container

reads from the current container element

{some-file-uri}

Look up the property on that exact file uri in the OpenCms VFS, fallback if no other valid option is selected for the file attribute.

There are also some deprecated options for the "file" value that are still supported but should not longer be used:

parent

same as uri

search-parent

same as search.uri

this

same as element.uri

search-this

same as search.element.uri
