From source file:fr.paris.lutece.portal.service.spring.SpringContextService.java

/**
 * Initialize a global Application Context containing all beans (core + plugins)
 * Now uses GenericApplicationContext for better performances. A wrong formatted file
 * will not block block context to be built (without the file), but a wrong bean (i.e. cannot
 * be instantiated) will cause a full context failure. Context is less "failure-friendly"
 * @param servletContext The servlet context
 * @throws LuteceInitException The lutece init exception
 * @since 2.4/*from   w w  w .j a va2s  .co  m*/
