getting-started

The getting-started project is a simple Jakarta EE application with a HTTP endpoint that is running in WildFly.

The src/main folder contains a simple 'Hello world' style Jakarta EE application using JAX-RS.

Building the application

To run the application, you use Maven:

mvn clean package

Maven will compile the application, provision a WildFly server The WildFly server is created in target/server with the application deployed in it.

Running the application

To run the application, run the commands:

cd target/server
./bin/standalone.sh

Once WildFly is running, the application can be accessed at http://localhost:8080/

Testing the application

To run integration tests to verify the application, you use Maven:

mvn clean package verify

Tests in src/test are run against the server in target/server.

Build Docker Image

$ podman build -t myapp:latest .

Run the Docker Image

podman run --rm -p 8080:8080 -p 9990:9990 --name=myapp myapp

Pushing to local Image Registry

Tag thr image:

podman tag myapp localhost:5000/myapp

Start a local registry:

podman run --rm -p 5000:5000 --name registry registry:latest
podman run --rm -p 5000:5000 --volume ~/.registry/storage:/var/lib/registry registry:latest

podman push localhost:5000/myapp --tls-verify=false

PostgreSQL

Start PostgreSQL:

podman run --rm --name my-postgres -p 5432:5432 -e POSTGRES_PASSWORD=admin -e POSTGRES_USER=postgres -e POSTGRES_DB=postgres postgres

Add some data to PostgreSQL:

podman exec -it my-postgres bash
psql -U postgres
CREATE TABLE TEST_TABLE (
  id SERIAL PRIMARY KEY,
  SOME_FIELD1 VARCHAR (50) NOT NULL,
  SOME_FIELD2 VARCHAR (50) NOT NULL
);
insert into test_table values (1, 'prova1', 'prova1');
insert into test_table values (2, 'prova2', 'prova2');
insert into test_table values (3, 'prova3', 'prova3');
commit;
select * from TEST_TABLE;
quit
exit

export POSTGRESQL_USER=postgres
export POSTGRESQL_PASSWORD=admin
export POSTGRESQL_HOST=localhost
export POSTGRESQL_PORT=5432
export POSTGRESQL_DATABASE=postgres
export POSTGRESQL_JNDI=java:jboss/datasources/PostgreSQLDS

mvn clean install

./target/server/bin/standalone.sh

curl -X POST http://localhost:8080/hello/test-table/insert/somedata1/somedata2

curl http://localhost:8080/hello/test-table/list
