public class ShowPropertyServlet
extends HttpServlet

Writes a property of a Node to the response OutputStream. The available paramater options are as follows:

- 1) Pass the node Id in as a request parameter. Eg. http://server:port/app/ShowProperty?nodeId=/repo/12345.
- 2) Pass the node path as part of the the request pathInfo. Eg. http://server:port/app/ShowProperty/repo/path/file.ext.
- 3) Pass the node path in as a request parameter. Eg. http://server:port/app/ShowProperty?nodePath=/repo/path/file.ext

  With any of the above, if you would like to display a property other than the primary property, simply put "//propertyName" at the end of the parameter/pathInfo.
