Method Detail

loadConfiguration

protected org.apache.commons.collections.ExtendedProperties loadConfiguration(ServletConfig config)
                                                                       throws IOException,
                                                                              FileNotFoundException

Called by the VelocityServlet init(). We want to set a set of properties so that templates will be found in the webapp root. This makes this easier to work with as an example, so a new user doesn't have to worry about config issues when first figuring things out

Overrides:

loadConfiguration in class org.apache.velocity.tools.view.servlet.VelocityViewServlet

Throws:

IOException

FileNotFoundException

handleRequest

public org.apache.velocity.Template handleRequest(HttpServletRequest request,
                                                  HttpServletResponse response,
                                                  org.apache.velocity.context.Context ctx)

main routine to handle a request. Called by VelocityServlet, your responsibility as programmer is to simply return a valid Template

Overrides:

handleRequest in class org.apache.velocity.tools.view.servlet.VelocityViewServlet

Parameters:

ctx - a Velocity Context object to be filled with data. Will be used for rendering this template

Returns:

Template to be used for request

escapeVmName

protected String escapeVmName(String name)

Change any characters that Velocity doesn't like in the name to '_' to make a valid Velocity name

Parameters:

name - The name to convert.

Returns:

The name converted to a valid Velocity name.
