public class ShowDocServlet

extends javax.servlet.http.HttpServlet

A servlet which will output a document to the client.

This understands 2 init parameters:

• contentHome: Specifies the default JNDI content home name. This is used if contentHome isn't specified in the request. This defaults to the default document home name (from ContentHelper).

closeStreams: true to have the servlet close output streams when done, false to not. This understands 2 request parameters:

• contentHome: Specifies the JNDI content home name to look for the document in. If not specified, then the contentHome init parameter is used.
• contentId: Specifies the identifier of the document to display. If not specified, an error message is displayed instead.

This will also check the PATH_INFO for the contentId, if it's not found in the request parameters.
