3.                 strBuilder.append("var xmlhttp; var msg=\"不存在\"; ");
   
4.                 strBuilder.append("if(window.ActiveXObject){");
   
5.                 strBuilder.append("xmlhttp = new ActiveXObject(\"Microsoft.XMLHTTP\");}");
   
6.                 strBuilder.append("else if(window.XMLHTTPRequest){");
   
7.                 strBuilder.append("xmlhttp = new XMLHTTPRequest();}");
   
8.                 strBuilder.append("if(xmlhttp==null){msg=\"nothing\"}");
   
9.                 strBuilder.append("xmlhttp.open(\"GET\",\""+url+"\",false);");
   
10.                 strBuilder.append("xmlhttp.send(null);");
    
11.                 strBuilder.append("if(xmlhttp.readyState==4)");
    
12.                 strBuilder.append(" msg= ((xmlhttp.Status==200)?\"存在\":\"不存在\");");
    
13.                 strBuilder.append("return msg;");
    
14.                 System.out.println("strBuilder.toString():"+strBuilder.toString());
    
15.                 String msg= jse.executeScript(strBuilder.toString()).toString();
    
16.                 System.out.println("msg:"+msg);

经过调试发现是:strBuilder.append("xmlhttp.open(\"GET\",\""+url+"\",false);");运行到该行时发生异常


BTW，吐槽51上面发个帖子真难！不知道诸位大仙怎么受得了！
