This is a simple project to show you how to use Java to access your Xero data via the Xero API. This project uses the 2-legged OAuth approach (OAuth 1.1a), referred to by the Xero API as Private Applications.

###Step 1: Setup a Xero application

Follow the instructions here: https://blog.xero.com/developer/api-overview/setup-an-application/#private-apps

###Step 2: Add your private key, consumer key and secret

Put your private key into: privateKey.pem Put your consumerKey and consumerSecret into: xeroApi.properties

The following keys are needed for Xero Private Application.

endpointUrl=https://api.xero.com/api.xro/2.0/
consumerKey=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
consumerSecret=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
privateKeyFile=./privateKey.pem

###Step 3: Get the Schemas

Start with the modified Xero API schemas here: https://github.com/rossjourdain/XeroAPI-Schemas

They should be up to date but if not, you can get the latest Xero API schemas here: https://github.com/XeroAPI/XeroAPI-Schemas

###Step 4: git clone https://github.com/indykish/xero.git

###Step 5: Add the schemas to src/main/resources/XeroSchemas/v2.00/

###Step 6: When mvn compile is executed the XeroSchemas/v2.00 xsd files are converted to Java classes.

This project uses the following projects:

-- Maven JAXB2 Plugin - XML to Java Object Unmarshalling -- https://confluence.highsource.org/display/MJIIP/Maven+JAXB2+Plugin https://confluence.highsource.org/display/MJIIP/User+Guide

-- Java OAuth - OAuth implementation -- https://code.google.com/p/oauth/

The maven-jaxb2-plugin plugin in pom.xml compiles XeroSchemas to Java classes.

<plugin>
			<groupId>org.jvnet.jaxb2.maven2</groupId>
			<artifactId>maven-jaxb2-plugin</artifactId>
			<executions>
				<execution>
					<goals>
						<goal>generate</goal>
					</goals>
				</execution>
			</executions>
</plugin>

When the project is loaded in eclipse, if the maven-jaxb2 plugin isn't present it is downloaded automatically.

This is a simple project to show you how to use Java to access your Xero data via the Xero API. This project uses the 3-legged OAuth approach (OAuth 1.1a), referred to by the Xero API as Public Application.

###Step 1: Setup a Xero application

Follow the instructions here: https://blog.xero.com/developer/api-overview/setup-an-application/#public-apps

###Step 2: Generate an OAuth access token (If you wish to test API access with Xero using standalone mode)

You can use the xerorails project to generate one.

''' git clone https://github.com/indykish/xerorails.git

Follow the instructions to as seen in xerorails to generate an access_token. '''

###Step 3: Add your consumer key and secret

Put your consumerKey and consumerSecret, oauth_token, oauth_verifier, oauth_token_secret into: xeroApi.properties

The following keys are needed for Xero Public Application.

oauth_token=XXXXXXXXXXXXXXXXX
oauth_verifier=XXXXXX
oauth_token_secret=XXXXXXXXXXXXXXXXXXXXX
requestUrl=https://api.xero.com/oauth/RequestToken
authorizationUrl=https://api.xero.com/oauth/Authorize
accessUrl=https://api.xero.com/oauth/AccessToken

###Step 4: Get the Schemas

Start with the modified Xero API schemas here: https://github.com/rossjourdain/XeroAPI-Schemas

They should be up to date but if not, you can get the latest Xero API schemas here: https://github.com/XeroAPI/XeroAPI-Schemas

###Step 5: git clone https://github.com/indykish/xero.git

###Step 6: Add the schemas to src/main/resources/XeroSchemas/v2.00/

When mvn compile is executed the XeroSchemas/v2.00 xsd files are converted to Java classes.

The class com.rossjourdain.util.XeroPublicClient should be used to interface with Xero.
