Alternative to deprecated functionality of RE in BOE 4.1

I haven't got access to the Web Service endpoint of a BOE 4.1 server due to port blocking (I suppose). However I can use Report Engine through Java SDK but some functionality returns NotImplementedException since version 4.0 .

e.g. DocumentInstance#getDictionary()

My goal is automate Webi reports documentation. I would extract some info as used universe objects, variables and block names from the report.

I am not optimistic about having access to the web service endpoint so I want to know if there is any other Java API or way of getting the information I need.

Thanks,

Jonás
