if(flag_page==1&&tag==HTML.Tag.A){
 flag_page=0;
 Display test3=new Display(text,prepreatt+"\n");
     SwingUtilities.invokeLater(test3) ;
 try {if(prepreatt!=null){
 URL ul=new URL(prepreatt);
  display.nextpage(ul,one[0],one[1]);}
} catch (MalformedURLException e) {
// TODO 自动生成 catch 块
e.printStackTrace();
}
 }
public void nextpage(URL purl,String zonglei,String flei){
pageurl=purl;
if(purl!=null){
Urllei ul=new Urllei();
ul.seturl(pageurl,zonglei,flei);
HTMLEditorKit.ParserCallback callback 
     = new search2(ul,store,textarea,application);//new search(ul,chaxun,store,textarea,page,application);
      
     try {
InputStream in = pageurl.openStream();
InputStreamReader r = new InputStreamReader(in);
ParserGetter kit = new ParserGetter();
    HTMLEditorKit.Parser parser2 = kit.getParser();
parser2.parse(r, callback, true);
} catch (IOException e) {
// TODO 自动生成 catch 块
e.printStackTrace();
}
}
}

是两个对象的互相调用直到prepreatt等于null应该没有死循环
