the configuration created based on the context

doCreate

protected DefaultApplicationConfigurationFactory.ApplicationConfigurationImpl doCreate(VaadinContext context,
                                                                                       FallbackChunk chunk,
                                                                                       Map<String,String> properties)

Creates application configuration instance based on provided data.

Parameters:

context - the Vaadin context, not null

chunk - the fallback chunk, may be null

properties - the context parameters, not null

getTokenFileFromClassloader

protected String getTokenFileFromClassloader(VaadinContext context)
                                      throws IOException

Gets token file from the classpath using the provided context.

The contextClass may be a class which is defined in the Web Application module/bundle and in this case it may be used to get Web Application resources. Also a VaadinContext context instance may be used to get a context of the Web Application (since the contextClass may be a class not from Web Application module). In WAR case it doesn't matter which class is used to get the resources (Web Application classes or e.g. "flow-server" classes) since they are loaded by the same ClassLoader. But in OSGi "flow-server" module classes can't be used to get Web Application resources since they are in different bundles.

Parameters:

context - a VaadinContext which may provide information how to get token file for the web application

Returns:

the token file content

Throws:

IOException - if I/O fails during access to the token file
