JavaEE Transaction Workshop

Important

This code relies heavily on artifacts specific to the SPF Finances/FOD Financieen. It can't therefore be compiled outside that environment.

This project aims to illustrate the different uses of transactions within JavaEE.

Installation

Docker

First, be sure that no other WebLogic instance is runnin, it could cause interferences, especially with ports. Then, run the Postgres and WebLogic containers:

docker compose up -d

WebLogic

Then create a new XA datasource for PostgreSQL:

Go to the URL http://localhost.finbel.intra:7272/console
In the domain structure tree on your left, select services/datasources
Create a new generic datasource
Enter sandbox.transactionDatasource both as name and JNDI name
Select PostgreSQL as type
There should be only one driver, the Type 4 one. Select it.
Check global transaction and then select validation (commit) in one phase
Then you have to input the data for JDBC:
- Database name: sandbox
- Host name: db
- Port: 5432
- Username: javaee
- Password: javaee
Finally, test the connection to see if everything's ok

Deploy the application

Launch:

mvn install -Pdeploy-local-docker
