我有一个小程序可以从特定文件夹上传一些文件并删除它们,但是当我从我的 javascript 代码调用一个小程序函数时出现问题,当我从init()
它调用该函数时工作正常。
我的小程序代码:
public class Uploader extends Applet {
String serverPath;
String clientPath;
private JSObject win;
@Override
public void init() {
serverPath = getParameter("serverPath");
clientPath = getParameter("clientPath");
try {
win = JSObject.getWindow(this);
} catch (JSException e) {
log.warning("Can't access JSObject object");
}
upload(topic,clientPath);
}
public void upload(String topic,String clientPath) {
log.log(Level.SEVERE, "upload functiond");
DefaultHttpClient client = new DefaultHttpClient();
MultipartEntity form = new MultipartEntity();
log.log(Level.SEVERE, "upload functiond2");
try {
File directory = new File(clientPath);
log.log(Level.SEVERE, "upload functiond2.2");
File[] files = directory.listFiles();
log.log(Level.SEVERE, "upload functiond2.5");
int i = 0;
for (File file : files) {
log.log(Level.SEVERE, "upload functiond2.6");
i++;
form.addPart("file" + String.valueOf(i), new FileBody(file));
System.out.println("adding file " + String.valueOf(i) + " " + file);
log.log(Level.SEVERE, "adding file " + String.valueOf(i) + " " + file);
}
log.log(Level.SEVERE, "upload functiond3");
form.addPart("topic", new StringBody(topic, Charset.forName("UTF-8")));
form.addPart("action", new StringBody(action, Charset.forName("UTF-8")));
form.addPart("path", new StringBody(serverPath, Charset.forName("UTF-8")));
HttpPost post = new HttpPost(serverPath);
....
这是我的javascript代码:
document.applet.upload(title,"c:\scan");
当我从 javascript 调用时,只打印日志:
log.log(Level.SEVERE, "upload functiond2.2");
请注意,当我从小init
程序的方法调用时,它工作正常。
我将我的代码包装成一个PriviligedAction
,但只前进了一步并坚持下去
log.log(Level.SEVERE, "upload functiond2.5");
