aid.security_domain=hex/A0 00 00 00 18 43 4D 08 09 0A 0B 0C 00 00 00

And For MMready1.0 card, you need modify something in your .gdp file to be able to load it in your real card.
Remove the SecurityDomainAid value in gdp file. For example,

1. Modify SecurityDomainAid="A0000000185201050000000030534357" to SecurityDomainAid=""
2. Modify ApplicationSpecificParameters="7110A0000000185201050000000040534357" to ApplicationSpecificParameters="7110A0000000185201050000000030534357"

Parsing Query in Smart Web Server

SharedByteString name = new SharedByteString();
SharedByteString value= new SharedByteString();
StringValueBuffer stringValueBuffer = new StringValueBuffer((short) 50, (short) 100); //short sizeRAM, short sizeEEPROM
FormParser formParser = new FormParser(true);
ByteString queryString = req.getQueryString();
if (queryString != null) {
 formParser.parse(this, queryString, stringValueBuffer, name,value);
}

Display response page in SCWS

HttpCardServletOutputStream

You can call it in following methods :

1. public void doDelete(HttpCardServletRequest req,httpCardServletResponse resp) throws Exception
2. public void doGet(HttpCardServletRequest req, HttpCardServletResponse resp)throws Exception
3. public void doHead(HttpCardServletRequest req, HttpCardServletResponse resp)throws UserException, Exception
4. public void doOptions(HttpCardServletRequest req,HttpCardServletResponse resp) throws Exception
5. public void doPost(HttpCardServletRequest req, HttpCardServletResponse resp)throws Exception
6. public void doPut(HttpCardServletRequest req, HttpCardServletResponse resp)throws Exception

byte [] hello = {'h','e','l','l','o'};
resp.setStatus(HttpCardServletResponse.SC_OK);
resp.setContentType(stringContainer.getConstantString(HttpStringContainer.TEXT_HTML_KEY));
HttpCardServletOutputStream out = resp.getOutputStream();
resp.setContentLength((short)5);
out.write(hello, (short) 0,(short)5);


Get Input stream content in Smart Card Web Server

HttpCardServletInputStream

You can call it in following methods :

1. public void doDelete(HttpCardServletRequest req,httpCardServletResponse resp) throws Exception
2. public void doGet(HttpCardServletRequest req, HttpCardServletResponse resp)throws Exception
3. public void doHead(HttpCardServletRequest req, HttpCardServletResponse resp)throws UserException, Exception
4. public void doOptions(HttpCardServletRequest req,HttpCardServletResponse resp) throws Exception
5. public void doPost(HttpCardServletRequest req, HttpCardServletResponse resp)throws Exception
6. public void doPut(HttpCardServletRequest req, HttpCardServletResponse resp)throws Exception

byte data;
byte[] content = JCSystem.makeTransientByteArray((short) req .getContentLength(), JCSystem.CLEAR_ON_RESET);

HttpCardServletInputStream in = req.getInputStream();
try {
for (short i = 0; i < content.length; i++)
{
data = in.read();
content[i] = data;
}
}
catch (EndOfStreamException e) { }
// or
in.read(content,0,content.length);

HttpCardServletContainer

It manages (add and remove) servlet

HttpCardServlet servlet
HttpCardServletContainer servletContainer;
static byte[] prefix = { '/', 'p','o','s','t'}
AID server = JCSystem.lookupAID(buffer, offset, aidLen);
servletContainer = (HttpCardServletContainer) JCSystem.getAppletShareableInterfaceObject( server, HttpCardServletContainer.HTTP_CARD_SERVLET_CONTAINER_SERVICE);
servletContainer.add(servlet, new ByteString(prefix));
servletContainer.remove(servlet)

You can call it http://URL/post

Parsing Form in Smart Web Server

There are 2 class that have been already provided FormHandler and FormParser.

FormHandler
We should implement FormHandler in class. This class has 3 methods, start , form and end.

Start : start of the document parsing, perhaps you can add some codes that initialized the value of variable

Form : Each form value will be known in here. Just compare the form value with the first input parameter.

End : end of the document parsing

for example :

import com.gemplus.javacard.multimedia.framework.ByteString;
import com.gemplus.javacard.multimedia.framework.FormHandler;

public class FormPosting implements FormHandler {

 public byte [] username;
 public byte [] usermail;
 private static final byte[] USERNAME={'u','s','e','r','n','a','m','e'};
 private static final byte[] USERMAIL={'u','s','e','r','m','a','i','l'};
 
 public void start() {
  username=null;
  usermail=null;
 }

 public void form(ByteString arg0, ByteString arg1) {
  
  if (arg0.compareTo(USERNAME, (short) 0, (short) USERNAME.length) == 0)
  {
   username = arg1.getBytes();
  }
  else if (arg0.compareTo(USERMAIL, (short) 0, (short) USERMAIL.length) == 0)
   usermail = arg1.getBytes();

 }
 
 
 public void end() {
  // TODO Auto-generated method stub
 }
 
}

FormParser

SharedByteString name = new SharedByteString();
SharedByteString value= new SharedByteString();
StringValueBuffer stringValueBuffer = new StringValueBuffer((short) 50, (short) 100); //short sizeRAM, short sizeEEPROM
FormParser formParser = new FormParser(true);

// some methods
HttpCardServletRequest req
byte data;
byte[] content = JCSystem.makeTransientByteArray((short) req.getContentLength(), JCSystem.CLEAR_ON_RESET);
stringValueBuffer.reset();

HttpCardServletInputStream in = req.getInputStream();
try {
 for (short i = 0; i < content.length; i++) {
       data = in.read();
       content[i] = data;
 }      } catch (EndOfStreamException e) { }
// URL encoded
formParser.parse(FormPosting, new ByteString(content), stringValueBuffer, name, value);
