Attached you will find Java classes which perform the GoodData data upload. These also show how to perform a full upload (data reload). Please take a look at the boolean fullUpload flag in the GdcRestApiWrapper.integrate. If you want to compile these classes, you need the following (open-source) components on the classpath:

commons-beanutils-1.8.0.jar
commons-logging-1.1.1.jar
ezmorph-1.0.6.jar
commons-collections-3.2.1.jar
log4j-1.2.14.jar
commons-codec-1.3.jar
junit-4.4.jar
commons-lang-2.4.jar
json-lib-2.2.3.jar
commons-httpclient-3.1.jar

Most of these files are part of Apache Commons project, and all of them can be downloaded from here: http://repo1.maven.org/maven2/.

I suggest you to look at class com.gooddata.rest.GdcRestApiWrapperTest, which shows you how easy is to upload a file. There's also some sample CSV file in the same directory as the mentioned class, which you can use to define an ETL interface within a project you will create.

The class com.gooddata.rest.upload.Uploader performs the same functions, but in a much less verbose way. This is recommended for production purposes.

Last thing that might be a little bit tricky is how to find the "your_project_id" parameter of the NamePasswordConfiguration class. The easiest way is to enter https://secure.gooddata.com/gdc/md. Then click on the name of your project, and you will see some hash in both the url and on top of the page. This is the ID.

If you want to verify name of the ETL interface, you can click further on "data" and "interfaces". However, it might be easier to copy&paste it from the Data tab of the application.

I hope that this is helpful
