Web module deployment settings

Use this page to configure an instance of Web module deployment.

To view this administrative console page, click Applications > Enterprise Application > application_instance > Web modules > Web_module_instance.

Attention: If an application is running, changing an application setting causes the application to restart. On stand-alone servers, the application restarts after you save the change. On multiple-server products, the application restarts after you save the change and files synchronize on the node where the application is installed.

URI

Specifies the relative location of the module within the application EAR.

Alternate deployment descriptor

Specifies the alternate deployment descriptor for the module as defined in the application deployment descriptor according to the J2EE specification.

Starting weight

Specifies the order in which modules are started. Lower weighted modules are started before higher weighted modules.

Class loader mode

Specifies whether the class loader should search in the parent class loader or in the application class loader first to load a class. The standard for JDK class loaders and WebSphere class loaders is Parent First. By specifying Parent Last, your application can override classes contained in the parent class loader, but this action can potentially result in ClassCastException or LinkageErrors if you have mixed use of overriden classes and non-overriden classes.

The options are Parent First and Parent Last. The default is to search in the parent class loader before searching in the application class loader to load a class.

Data type String
Default Parent First
