Using the CWA REST API

Java Client REST API Examples

BufferedReader reader = 

 BufferedReader(

 InputStreamReader(

conn.getInputStream()));

  String resp = "";

  String next = 

;

  

 ((next = reader.readLine()) != 

)

resp += next;

  System.

.println(resp);

}

Code Example 3 – Session Management Using the Session Cookie

In both previous code examples, the calls establish new sessions on the server. For typical applications that make 
repeated calls to the REST API, the best practice is to reuse the established sessions so that the server does not create 
excessive number of active sessions, which eventually could cause it to run out of memory.

Code Example 3 is an extension of Code Example 1 showing the usages of a cookie for session management. 

 tesGetRequestWithSession() 

 Exception

{

String sessionID = 

;

 i=0; i<10; i++)

{

URL url = 

 URL(

"http://www.mycompanyscheduler.com:8080/api/tes-6.2/Job.getList"

);

HttpURLConnection conn = (HttpURLConnection) url.openConnection();

conn.setRequestMethod("

GET

");

conn.setDoInput(

);

conn.setDoOutput(

);

 (sessionID == 

)

{

  String userNamePassword = " 

myusername:mypassword 

";

  userNamePassword = 

        

 String(org.apache.commons.codec.binary.Base64.encodeBase64(userNamePassword

.getBytes()));

  conn.setRequestProperty("

Authorization

", userNamePassword);

}

{

  conn.setRequestProperty("Cookie", sessionID);

}

conn.connect();

BufferedReader reader = 

 BufferedReader(

 InputStreamReader(

conn.getInputStream()));

String resp = "";

String next = 

;

 ((next = reader.readLine()) != 

)

   resp += next;

System.

.println(resp);

//extract cookie

String setCookies = conn.getHeaderField(

"Set-Cookie"

);

 (setCookies != 

 && sessionID == 

)

{

  String cookies[] = setCookies.split(";");

  

 (cookies.

length

 > 0)

  

sessionID = cookies[0];

}

   }

}
