이번에 처음으로 서블릿을 사용하는데 애플릿에서는 url을 이용해서 하면 연결이 되는데 서블릿으로 이용해서 어떤 객체에 집어 넣어야 할 지 잘 모르겠습니다...
아래와 같이 예제가 있으니 자바의 고수여러분을 제발 가르쳐 주세요...
<Applet 예제>
public class SearchYahoo extends SearchService {
public void init() {
baseURL = "http://search.yahoo.co.kr/bin/search?p=";
System.out.println(baseURL);
serviceName = "Lycos";
setup();
}
}
import java.applet.Applet;
import java.awt.*;
import java.net.*;
public class SearchService extends Applet{
private TextField searchField;
protected String baseURL,serviceName, frame ="Results";
protected int textFieldSize = 30;
public void setup(){
Panel inputPanel = new Panel();
inputPanel.add(new Label("Search String:" ));
searchField = new TextField(textFieldSize);
inputPanel.add(searchField);
add(inputPanel);
add(new Button("Search " + serviceName));
}
public boolean action(Event event, Object object){
String searchString = URLEncoder.encode(searchField.getText());
showSearch(searchString);
return(true);
}
public void showSearch(String searchString){
try{
URL url = new URL(baseURL + searchString);
getAppletContext().showDocument(url, frame);
}catch(MalformedURLException mue){
System.out.println("Illegal URL:" +baseURL +searchString);
}
}
}
