Allowing remote socket connection in an applet?
Sep 7th, 2009, 8:18pm  
In an applet, how should I go about opening a socket to a remote server through a socket? I know that this is a security restriction of java. Any pointers or links would be much appreciated. (Also I am not that good with socket, a good link to resources on this subject would be good too).

You must at least sign the applet. And if you explain what you plan to do with this socket, information might be more precise.

I am just displaying the information on a graph, so it shouldn't be too difficult, right? (other than signning the applet). If possible I would also like to log the data... but is that asking too much?

"what you plan to do with this socket", not with the gathered data...
If you just want to access a Web server, you can look at the Network library, it even has an example (HTTPClient) showing how to do it. You can pass parameters on the URL, analyse response, etc.

Logging the data from an applet might be hard: you don't know where to put the files, depending on the client system. And Java is quite restrictive on this, as you can mess up the system or introduce malware this way...
