Add a String Value to a Cache
The following is an example of using Java to add a string value to a cache:
public class RestExample {
/**
* Method that puts a String value in cache.
* @param urlServerAddress
* @param value
* @throws IOException
*/
public void putMethod(String urlServerAddress, String value) throws IOException {
System.out.println("----------------------------------------");
System.out.println("Executing PUT");
System.out.println("----------------------------------------");
URL address = new URL(urlServerAddress);
System.out.println("executing request " + urlServerAddress);
HttpURLConnection connection = (HttpURLConnection) address.openConnection();
System.out.println("Executing put method of value: " + value);
connection.setRequestMethod("PUT");
connection.setRequestProperty("Content-Type", "text/plain");
connection.setDoOutput(true);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(connection.getOutputStream());
outputStreamWriter.write(value);
connection.connect();
outputStreamWriter.flush();
System.out.println("----------------------------------------");
System.out.println(connection.getResponseCode() + " " + connection.getResponseMessage());
System.out.println("----------------------------------------");
connection.disconnect();
}
public class RestExample {
/**
* Method that puts a String value in cache.
* @param urlServerAddress
* @param value
* @throws IOException
*/
public void putMethod(String urlServerAddress, String value) throws IOException {
System.out.println("----------------------------------------");
System.out.println("Executing PUT");
System.out.println("----------------------------------------");
URL address = new URL(urlServerAddress);
System.out.println("executing request " + urlServerAddress);
HttpURLConnection connection = (HttpURLConnection) address.openConnection();
System.out.println("Executing put method of value: " + value);
connection.setRequestMethod("PUT");
connection.setRequestProperty("Content-Type", "text/plain");
connection.setDoOutput(true);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(connection.getOutputStream());
outputStreamWriter.write(value);
connection.connect();
outputStreamWriter.flush();
System.out.println("----------------------------------------");
System.out.println(connection.getResponseCode() + " " + connection.getResponseMessage());
System.out.println("----------------------------------------");
connection.disconnect();
}

Get a String Value from a Cache
The following code is an example of a method used that reads a value specified in a URL using Java to interact with the JBoss Data Grid REST Interface.
/**
* Method that gets an value by a key in url as param value.
* @param urlServerAddress
* @return String value
* @throws IOException
*/
public String getMethod(String urlServerAddress) throws IOException {
String line = new String();
StringBuilder stringBuilder = new StringBuilder();
System.out.println("----------------------------------------");
System.out.println("Executing GET");
System.out.println("----------------------------------------");
URL address = new URL(urlServerAddress);
System.out.println("executing request " + urlServerAddress);
HttpURLConnection connection = (HttpURLConnection) address.openConnection();
connection.setRequestMethod("GET");
connection.setRequestProperty("Content-Type", "text/plain");
connection.setDoOutput(true);
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
connection.connect();
while ((line = bufferedReader.readLine()) \!= null) {
stringBuilder.append(line + '\n');
}
System.out.println("Executing get method of value: " + stringBuilder.toString());
System.out.println("----------------------------------------");
System.out.println(connection.getResponseCode() + " " + connection.getResponseMessage());
System.out.println("----------------------------------------");
connection.disconnect();
return stringBuilder.toString();
}
/**
* Method that gets an value by a key in url as param value.
* @param urlServerAddress
* @return String value
* @throws IOException
*/
public String getMethod(String urlServerAddress) throws IOException {
String line = new String();
StringBuilder stringBuilder = new StringBuilder();
System.out.println("----------------------------------------");
System.out.println("Executing GET");
System.out.println("----------------------------------------");
URL address = new URL(urlServerAddress);
System.out.println("executing request " + urlServerAddress);

connection.connect();

stringBuilder.append(line + '\n');
}
System.out.println("Executing get method of value: " + stringBuilder.toString());
System.out.println("----------------------------------------");
System.out.println(connection.getResponseCode() + " " + connection.getResponseMessage());
System.out.println("----------------------------------------");
connection.disconnect();
return stringBuilder.toString();
