$context  = stream_context_create($opts);

Could anyone tell me similar function on jsp

http_build_query() is php function, similar function in Jsp is what?

stream_context_create() also php function

Answer 1

With scriptlets you can call java libraries in jsps.

For http_build_query , the analog in Java is the URLEncoder class. Here's a simple tutorial on how to use it.

For stream_context_create , I guess you want to send an http request to a server, the analog in Java is Java.net . See this post for mini a torial .
