hi,
In my applet I build a URLConnection, it connect a jsp file. In my jsp file I refer to a javaBean. I send two objects of request and response in jsp to javaBean. In javabean return output stream to URLConnect. At that time a error happened.WHY???
Thanks.
My main code:
APPLET
TestApplet)
URL url = new URL("http://210.0.8.120/jsp/test.jsp";
URLConnection con;
con = url .openConnection();
con = servlet.openConnection();
con.setDoInput( true );
con.setDoOutput( true );
con.setUseCaches( false );
con.setRequestProperty( "Content-Type","text/plain" );
con.setAllowUserInteraction(false);
ObjectOutputStream out;
out = new ObjectOutputStream(con.getOutputStream());
Serializable[] data ={"test"};
out.writeObject( data );
out.flush();
out.close();
//until here are all rigth
ObjectInputStream in = new ObjectInputStream( con.getInputStream() );//happened error
......
JSP:
TestBean testBean = new TestBean ();
testBean .execute(request, response);
JAVABEAN:
public void execute( HttpServletRequest request,
HttpServletResponse response )
{
ObjectInputStream in =
new ObjectInputStream(request.getInputStream());
String direct = (String) in.readObject();
System.out.prinltn("direct");
ObjectOutputStream out = new ObjectOutputStream( response.getOutputStream() );
SerializableSerializable[] data ={"answer"};
out.writeObject( data );
out.flush();
out.close();
}
Error detail:
