波蘭語字符的問題CodenameOne和WebService

Question

我有一個web應用程序，它使用apache-tomcat部署的UTF8編碼。在「ąęćńźżół」中使用波蘭語字符發送servlet參數中的數據不是問題。他們解釋得很好。但是，當將字符串發送回CodenameOne時，我得到的只是Ä？一個？ ?? ??一個？ ??。

servlet代碼：

protected void processRequest(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException { 
request.setCharacterEncoding("UTF-8"); 
response.setContentType("text/html;charset=UTF-8"); 
PrintWriter out = response.getWriter(); 
try { 
String ID; 
String answer = "no answer";  
ID = request.getParameter("Id"); 
answer="ą ę ż ź ć ó"; 
//this is an answer to the client – Codename one   
out.print(answer);       
} finally {   
out.close(); 
} 
} 

CodenameOne代碼：

response = "empty"; 
try {   
//the NetworkManager object 
NetworkManager networkManager = NetworkManager.getInstance(); 
networkManager.start(); 
networkManager.addErrorListener(new ActionListener() { 
public void actionPerformed(ActionEvent evt) { 
    NetworkEvent n = (NetworkEvent) evt; 
    n.getError().printStackTrace();       
}}); 
//ConnectionRequest object 
ConnectionRequest request = new ConnectionRequest() { 
int chr; 
StringBuffer sb = new StringBuffer();     
protected void readResponse(InputStream input) throws IOException { 
//reading the answer      
while ((chr = input.read()) != -1){ 
sb.append((char) chr); 
} 
response = sb.toString();           
response = response.trim(); 
} 
protected void handleException(Exception err) { 
//An error occured - show a message: 
Dialog.show("Yikes!!", "Are you connected to the internet? Check your connection", "Ok", null); 
} 
}; 

request.setUrl("http://localhost:8080/FirstOneTomcat/Response"); //servlet calling 
request.setPost(false); 
request.addArgument("ID","ńćżźóąę"); //sending a the parameter Id to the servlet         
} catch (Exception e) { 
System.out.println(e.getMessage()); 
}     
while(response.equals("empty")) { 
//waiting for the answer from the serlvet or jsp server 
System.out.println("No response from server"); 
} 
//set the label with the information from the server 
findLabelKom().setText(response);

您嵌入拋光到服務器的源代碼，這意味着編譯器需要挑選編碼，它可以做任何事情。使用native2ascii工具將您的波蘭語轉換爲\ uation（注意，您沒有輸入UTF，而是使用波蘭語編碼）。

或者您可以在編譯源代碼時配置IDE的編譯器編碼。
