Field Detail

VAADIN_APPLICATION_BEAN_NAME

public static final String VAADIN_APPLICATION_BEAN_NAME

applicationClassName

private String applicationClassName
Name of the class that extends com.vaadin.Application. We don't retain the actual Class instance directly due to Grails class reloading - the Application class or any that it references could be reloaded dynamically at runtime during development, so we look up the class with this name from the classloader every time it is requested when creating a new Application instance.

Method Detail

doGetClassLoader

private ClassLoader doGetClassLoader()

getApplicationClass

@Override
@SuppressWarnings({ "unchecked" })
protected Class getApplicationClass()

getClassLoader

@Override
protected ClassLoader getClassLoader()
Returns the Grails ClassLoader, because the servlet's ClassLoader can't see the Grails application source.
throws:
ServletException
Returns:
the ClassLoader stored in the org.codehaus.groovy.grails.commons.GrailsApplication

getGrailsApplication

public org.codehaus.groovy.grails.commons.GrailsApplication getGrailsApplication()

getNewApplication

@Override
protected Application getNewApplication(HttpServletRequest request)

init

@SuppressWarnings("unchecked")
@Override
public void init(ServletConfig servletConfig)
Called by the servlet container to indicate to a servlet that the servlet is being placed into service.

This implementation caches the application class name (not the class itself) to use to acquire the Application class from the Grails classloader at runtime.

throws:
ServletException if an exception has occurred that interferes with the servlet's normal operation.
Parameters:
servletConfig - the object containing the servlet's configuration and initialization parameters

service

@Override
protected void service(HttpServletRequest httpReq, HttpServletResponse response)

writeAjaxPageHtmlVaadinScripts

@Override
protected void writeAjaxPageHtmlVaadinScripts(Window window, String themeName, Application application, java.io.BufferedWriter out, String appUrl, String themeUri, String appId, HttpServletRequest request)
Adds the JavaScript libraries configured in VaadinConfig to the head of the HTML page.
