Profiles with an HTTP(S) Input Agent are called by HTTP request.

Calling with a Java Program

The following listing shows the source code for a Java program that calls a profile with an HTTP(S) Input Agent. The data sent is in CSV format.

import java.io.BufferedInputStream;
import java.io.DataOutputStream;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
//Simple example to trigger profile with an HTTP(S) Input Agent
public class TestHttpAgent {
//Connect to Lobster_data HTTP(S) server and trigger profile
public static void main (String[] args) {
try {
//Parameters to match correct profile.
String params = "?param1=value1&param2=value2&param3=value3&param4=value4";
//Create Connection to Lobster_data HTTP server
URL url = new URL("http", "localhost", 80,"/dw/Request/example" + params);
HttpURLConnection con = (HttpURLConnection)url.openConnection();
con.setRequestProperty("Content-Type", "");
//Use POST method
con.setDoOutput(true);
con.connect();
//Input data for profile
DataOutputStream out = new DataOutputStream(con.getOutputStream());
out.writeBytes("value11 , value12 , value13\n"
+ "value21, value22, value23\n"
+ "value31, value32, value33");
//Read and print response
InputStream in = con.getInputStream();
BufferedInputStream bufIn = new BufferedInputStream(in);
int len = 0;
byte[] response = new byte[100];
while (len >= 0) {
len = bufIn.read(response);
if (len > 0)
System.out.print(new String(response, 0,len));
}
} catch (Exception ex) {
ex.printStackTrace();
} finally {
//Cleanup
in.close();
out.close();
}
}
}

Calling with a Browser

Another way to call the Input Agent is a file upload via a browser. The user will be provided with an HTML form through which he can send his data to Lobster_data. The following screenshot shows how such a form can look like.

The following listing shows the HTML source code for the form.
