Implement trading view in Java Application

[antonylim]

Hi, I use JSP for the front end and Java Spring for the backend.
for the front end I copy the index.html part and change the datafeedUrl to my API.
in backend, I create some API:

1. http://localhost:8084/infovesta/saham/data/symbols
2. http://localhost:8084/infovesta/saham/data/history
3. http://localhost:8084/infovesta/saham/data/config
4. http://localhost:8084/infovesta/saham/data/time
5. http://localhost:8084/infovesta/saham/data/search
6. http://localhost:8084/infovesta/saham/data/symbols

all API use hardcode values, just for testing purposes.
It's not called http://localhost:8084/infovesta/saham/data/history API, so the graph did not show, what should I do?

Hello @antonylim ,

Could you please set the property in the widget constructor as debug: true, repeat loading of the page and send the log to us?

Hello @antonylim

One "0" seems to be missing from "0930-163", should be "0930-1630", most likely in the session or corrections information.

Hi @GeorgiiMatveev-tv ,
i have succeed using TV Chart, but there are some error, can you give me pointer to resolved them?

@antonylim , I suggest to address the CORS first, you'd need to implement your own storage for production, ours is only avaialbe for testing purposes on localhost.
