Hi Andy, all the documentation for the Java API is available from http://www.biomart.org/other/rc6_documentation.pdf (page 85, section 11.6). However you know this already because you are using an example from there. You must however make sure that your registry xml file is in the 0.8 format (you can pick up an example of such file from the 'registry' directory). Pleae let me know if you have problems finding it. The registry file in your email is in 0.7 version format so it is not going to work with your code.
