# Samples-java-helloworld
This is a simple hello world example to show a JDBC connection to InterSystems IRIS. For more information about using this sample, please see [documentation](https://irisdocs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cls?KEY=AB_idesetup).
## To run this code in InterSystems Learning Labs or Evaluator Edition (on AWS, GCP, or Azure)
1. Open Samples-java-helloworld/Simple/HelloWorld.java
2. Comment out line 4 (since we won't need the package declaration here)
`//package com.intersystems.samples;`
3. For AWS, GCP, or Azure ONLY: Edit line 14 to change the ip to "try-iris" (Please skip this step if using InterSystems Learning Labs)
4. In the terminal window type:
`cd Samples-java-helloworld/simple`
`javac -cp ".:intersystems-jdbc-3.2.0.jar" HelloWorld.java`
`java -cp ".:intersystems-jdbc-3.2.0.jar" HelloWorld`
## To run this code locally
1. Clone this repo
2. Open the repo in your favorite Java IDE (such as Eclipse, IntelliJ, or NetBeans)
3. Open Samples-java-helloworld/simple/HelloWorld.java and verify ip, password, port, and username are right. Update as necessary.
