This service manages a stock portfolio. The data is backed by two DB2 tables, communicated with via JDBC. The following operations are available:

GET / - gets summary data for all portfolios.

POST /{owner} - creates a new portfolio for the specified owner.

GET /{owner} - gets details for the specified owner.

PUT /{owner} - updates the portfolio for the specified owner (by adding a stock).

DELETE /{owner} - removes the portfolio for the specified owner.

All operations return JSON. A portfolio object contains fields named owner, total, and loyalty, plus an array of stocks. A stock object contains fields named symbol, shares, price, total, and date. The only operation that takes any query params is the 'PUT' operation, which expects params named symbol and shares.

For example, doing a PUT http://localhost:9080/portfolio/John?symbol=IBM&shares=123 (against a freshly created portfolio for John) would return JSON like {"owner": "John", "total": 19120.35, "loyalty": "Bronze", "stocks": [{"symbol": "IBM", "shares": 123, "price": 155.45, "total": 19120.35, "date": "2017-06-26"}]}.

The above REST call would also add a row to the Stocks table via a SQL statement like INSERT INTO Stock (owner, symbol, shares, price, total, dateQuoted) VALUES ('John', 'IBM', 123, 155.45, 19120.35, '2017-06-26'), and would update the corresponding row in the Portfolio table via a SQL statement like UPDATE Portfolio SET total = 19120.35, loyalty = 'Bronze' WHERE owner = 'John'.

Note that the db2jcc4.jar file needs to be in the war file's 'WEB-INF/lib' directory. As a to-do, need to update the code to use a Liberty datasource, and make corresponding updates to the server.xml to define a JDBC provider for DB2 and to make that datasource available via JNDI lookup. For now, this service just talks to JDBC the Java SE way instead.
