Hey I am new here in StackOverFlow
Actually I am trying to get data from an official database(https://emf2.bundesnetzagentur.de/karte/Default.aspx). I use java and try to get the information with a post request with parameters. I wrote two different versions, one with the Apache httpclient and one with java.net. I also have a version written in Python(not mine)
The one in java doesn't work! I get at least this error as response:
Statuscode: 500 Internal Server Error
{"d":{"Message":"Fehler bei der Suche nach Funkanlagenstandorten.","StackTrace":"","Source":"","InnerException":""}}

Can somebody please help me?
Your code seems to work. I just tried it and only changed the coordinates value provided in your sample with some extracted from my browser debug console and it works:
{"nord":51.7151177895987,"ost":12.70294189453125,"sued":9.857482910156252,"west":50.49770501038011}
My guess is that you should ensure that there is no mistake in your BoundingBox class and that the range of each coordinate values is appropriate.
