Question

This code working fine

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://localhost:8090/Servlet/ServletFirst?to=1234&from=567&text=testtest");

If i use space between parameter value. It throws exception

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet("http://localhost:8090/Servlet/ServletFirst?to=1234&from=567&textParam=test test");

space between test test throws error. How to resolve?

`%20`............? I think there's an URL encoder laying around somewhere... — MadProgrammer, Oct 03 '13 at 07:16

You must URL encode the parameter in your URL; use %20 instead of the space.

HttpGet request = new HttpGet("http://localhost:8090/Servlet/ServletFirst?to=1234&from=567&textParam=test%20test");

Java has a class to do do URL encoding for you, URLEncoder:

String param = "test test";
String enc = URLEncoder.encode(param, "UTF-8");

String url = "http://...&textParam=" + enc;

Just use a %20 to represent a space.

This is all part of the URL encoding: http://www.w3schools.com/tags/ref_urlencode.asp

So you would want:

HttpGet request = new HttpGet("http://localhost:8090/Servlet/ServletFirst?to=1234&from=567&text=test%20test");

Use

URLEncoder.encode("test test","UTF-8")

So change your code to

HttpGet request = new HttpGet("http://localhost:8090/Servlet/ServletFirst?to=1234&from=567&textParam="+URLEncoder.encode("test test","UTF-8"));

Note Don't Encode Whole url

URLEncoder.encode("http://...test"); // its Wrong because it will also encode the // in http://

Use %20 to indicate space in the URL, as space is not an allowed character. See the Wikipedia entry for character data in a URL.

HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet(
    "http://localhost:8090/Servlet/ServletFirst?to=1234&from=567&textParam=test%20test");
