quickstarts-java

This code shows how to connect a Java application to an InterSystems server using JDBC, XEP, Hibernate, the Native Java API, and multi-model programming.

This repository is used in the Java QuickStart.

• xepplaystocksTask6.java to see how to quickly store objects
• nativeplaystocksTask5.java to see how to run methods within InterSystems IRIS
• multiplayTask4.java to see multimodel access using JDBC, XEP, and Native API
• hibernateplaystocksTask6.java to see how to use a third-party tool to work with objects

Configuration files

src/Solutions/config.txt: contains connection details for JDBC, XEP, Native API and multi-model.
src/hibernate.cfg.xml: contains connections details, parameters and initial settings for Hibernate.

How to use this sample

1. Verify you have an InterSystems server, and an IDE that supports Java, such as Visual Studio Code.
2. Clone this repo and open it in your IDE.
3. Get the latest Java drivers from your InterSystems installation directory and place them in the lib folder. See InterSystems documentation full instructions on (getting the latest InterSystems Java drivers)[https://docs.intersystems.com/components/csp/docbook/DocBook.UI.Page.cls?KEY=ADRIVE#ADRIVE_jdbc].
4. Import and compile two class files within iris-load into the USER namespace on your InterSystems server do $system.OBJ.Load(path_"DemoStockCls.xml") compile do $system.OBJ.Load(path_"StocksUtil.xml") compile
5. Load data from iris-load into the USER namespace on your InterSystems server do ##class(Demo.Stock).LoadData(path_"all_stocks_1yr.csv")
6. Open config.txt file, located inside the Solutions package, and modify the IP and password to be the correct values for your InterSystems IRIS instance. Although port and username are most likely the defaults, you should verify those as well.

How to use the Hibernate sample

1. Follow the instructions in InterSystems documentation for setting up Hibernate drivers.

2. Due to its complexity, Hibernate has its own config file named hibernate.cfg.xml. Open hibernate.cfg.xml file, located inside the src folder, and modify the IP and password to be the correct values for your InterSystems IRIS instance. Althoug port and username are most likely the defaults, you should verify those as well.

You should now have several classes for JDBC, XEP, Native API, multi-model and Hibernate inside the Solutions package.
