Provides access to OpenCms and System related information.
This tag supports the following special "property" values:
opencms.version returns the current OpenCms version, e.g. 5.0 Kaitain
opencms.url returns the current request URL, e.g.
http://localhost:8080/opencms/opencms/index.jsp
opencms.uri returns the current request URI, e.g.
/opencms/opencms/index.jsp
opencms.webapp returns the name of the OpenCms web application, e.g.
opencms
opencms.webbasepath returns the name of system path to the OpenCms web
application, e.g. C:\Java\Tomcat\webapps\opencms\
opencms.request.uri returns the name of the currently requested URI in
the OpenCms VFS, e.g. /index.jsp
opencms.request.element.uri returns the name of the currently processed element,
which might be a sub-element like a template part,
in the OpenCms VFS, e.g. /system/modules/org.opencms.welcome/jsptemplates/welcome.jsp
opencms.request.folder returns the name of the parent folder of the currently
requested URI in the OpenCms VFS, e.g. /
opencms.request.encoding returns the content encoding that has been set
for the currently requested resource, e.g. ISO-8859-1
All other property values that are passes to the tag as routed to a standard
System.getProperty(value) call,
so you can also get information about the Java VM environment,
using values like
java.vm.version or
os.name.
If the given property value does not match a key from the special OpenCms values
and also not the system values, a (String) message is returned with a formatted
error message.
