Opening URL Connection within websphere

Question

I have a local websphere server that I want to use to pull content from a webpage. when I make a get request to the server, I get a huge error. It seems to be getting triggered by getting the input stream from the connection..

Here's my code (not actually trying to read from google it's just a placeholder)

URL url = new URL("https://google.ca");

URLConnection conn = url.openConnection();

BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));

It only breaks when I enter the third line, I get this error

any help would be greatly appreciated.

Answer 1

Likely a firewall issue, the TCP connect() to google.ca timed out. You'd probably meet the same result If you can test outside of the application server on the same system.
