• 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
