AcrossWebModule is a basic building block of pretty much every Across application. It activates Spring MVC support for all modules in the Across context. This means modules can configure Spring MVC features, adding things like controllers, servlets and filters. On top of regular Spring MVC components, AcrossWebModule adds the following out of the box: Thymeleaf template rendering with a custom Thymeleaf dialect for interacting with the Across web infrastructure infrastructure for templates, menu building and registering web resources

The AcrossHibernateJpaModule activates JPA support for an entire Across application. It allows other modules to subscribe their entities to the shared JPA EntityManager represented by the AcrossHibernateJpaModule. The JPA implementation is built on top of Hibernate.

The SpringSecurityModule activates Spring security in the Across context and allows other modules to make use of the security infrastructure, as well as to make security configuration changes (eg. register additional security filters). It also provides some additional infrastructure for custom security principals. This module is required to work with Spring security in an Across application. It is a replacement for the Spring Boot security starter in an Across setup.

Activates support for @DebugWebControllers in other modules. Provides facilities for introspecting a running AcrossContext configuration.

Activates Ehcache cache management support and provides debug controllers to view and manage the cache.

Provides logging facilities for modules along with debug controllers to configure it.

The BootstrapUiModule provides a component layer for generating Bootstrap (v4) based web controls from Java code. The controls are built on top of the Across Web ViewElement infrastructure.

This module is a base component for building user interfaces. Other modules like AdminWebModule and EntityModule build on top of it.

The AdminWebModule provides infrastructure for building a secured administration section in your site. It sets up a default security layer with a form login, and provides a Bootstrap based layout for the UI.

EntityModule provides the developer with infrastructure for building user interfaces to manage the entities of an application.

Centralized way of providing information about the running application (e.g. start time, build number).

Provides services and facilities to manage collections of strong typed properties in a dbms.

The SpringSecurityAclModule provides infrastructure for securing your application using Access Control Lists (ACLs). It is built on top of Spring Security ACL. Adding SpringSecurityAclModule to your application will set up all infrastructure to create and manage ACLs, as well as to evaluate them using Spring security (in any module). This module requires an RDBMS datasource to create the tables for holding the ACL data. Components are also provided to easily build a user interface for updating ACLs using EntityModule.

Provides a domain model for users, groups, roles and permissions. Integrates automatically with Admin Web Module and Security Module, so you can immediately authenticate with these users and perform role based security checks.

LdapModule provides a services for connecting to LDAP directories. It provides a domain model for configuring LDAP connections and integrating them with an authentication layer. If UserModule is also present support for synchronizing users and groups from LDAP will also be active.

Provides OAuth 2 related domain model and infrastructure using the deprecated Spring Security OAuth 2 project and the UserModule domain model.

Across standard module that provides a set of uniform services for managing files in different types of file/blob repositories.

ImageServerCoreModule provides functionality for serving images in different resolutions. It can be used as an alternative to an actual Image CDN like Cloudinary when you need to have the functionality inside your app (or local network).

ImageServerAdminWebModule adds some Admin Web controllers for managing basic things of your ImageServer:

• managing resolutions
• uploading an image
• viewing an image by its unique key

WebCmsModule provides some basic web content management features for your Across application.
