Simple Java and Maven example of TDA Client.
git clone https://github.com/studerw/tda-client-example.git
Add your client id (customer key) and refresh token to the src/main/resources/tda-api.properties file.
Make sure you then add this file to .gitignore so you don't accidentally check in sensitive data
to a public repository.
echo 'src/main/resources/tda-api.properties' >> .gitignore
mvn clean install
Run the MainExample class in your IDE. Or from the command line:
mvn exec:java -Dexec.cleanupDaemonThreads=false
On Windows, you'll probably have to add quotes to the -Dexec....
Depending on how you've configured the logback.xml file in src/main/resources,
you'll end up with as little output as the following:
user@ubuntu:~/workspace/github/tda-client-example$ mvn exec:java -Dexec.cleanupDaemonThreads=false

If you see this, it means you've got an expired or otherwise incorrect OAUTH token. Take a look at the Creating a TDA Refresh Token for more information.
