Ok this is mysql database, java using eclipse springboot webapp. Everything works but the data comes back as one big unformatted blob on the jsp page when going to web site localhost:8080/index. I know I am almost there but somethings not 100% correct.I removed the jsp datatable part on the jsp and got the same result, so the page is apparently not seeing that but I dont know why?
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.service.ServiceInterface;
import model.ScraperObject;
@RestController
public class HomeRestController {
@Autowired
private ServiceInterface scraperService;
@RequestMapping(path="/index", method=RequestMethod.GET)
public List<ScraperObject> getAllNonDectivatedData(){
List<ScraperObject> allNonDectivated = scraperService.getAllNonDeactivatedOnes();
return allNonDectivated;
}
}

I don't know Java I'm afraid, so I can't help in that respect. If you need a hand with the Java stuff, you'd probably be best asking on StackOverflow.
What do you get in your browser if you load
/scrapedDatadirectly (with the domain name, whatever that might be of course)? Also, can you use the debugger to give me a trace please - click the Upload button and then let me know what the debug code is.Thanks,
