The TransactionScoped Annotation CDI Sample Application

This sample application uses the @TransactionScoped annotation on a bean and injects this bean within a transactional context.

Description

This demo uses a servlet to inject two beans annotated with the @TransactionScoped annotation. The example is divided in three scenarios:

Scenario 1 demonstrates that all injections of a bean within a single transaction use the same bean instance.
Scenario 2 demonstrates that injections of a bean in different transactions use different bean instances.
Scenario 3 demonstrates that beans annotated with the @TransactionScoped annotation must be invoked within a transactional context.

User can click on the submit button in provided index.html or invoke servlet at http://<host>:<port>/<context-root>/TransactionScopedServlet runs the three scenarios and presents the result as HTML output.

Building, Deploying, and Running the Application

Perform the following steps to build, deploy, and run the application:

Set up your build environment and configure the application server with which the build system has to work by following the common build instructions.
app_dir is the sample application base directory: samples_install_dir/javaee7/cdi/transaction-scoped.
Change directory to app_dir.
Build, deploy, and run the sample application using the run outcome.
mvn clean verify cargo:run
Use the clean outcome to undeploy the sample application and to remove the temporary directories such as build and dist.
mvn clean
