java - Blackberry http 连接需要任何模拟器吗？

Question

我正在尝试从我的黑莓模拟器测试 HTTP 连接，但没有任何反应。我需要 MDS 模拟器来运行这个应用程序吗？我正在使用 Eclipse Helios BlackBerry Java Plug-in 1.5.0。我还在系统中安装了黑莓 JDE。

void getViaHttpConnection(String url) throws IOException {
        HttpConnection c = null;
        InputStream is = null;
        int rc;

        try {
            c = (HttpConnection)Connector.open(url);
            RichTextField rt = new RichTextField("TEST LENGTH");
            // Getting the response code will open the connection,
            // send the request, and read the HTTP response headers.
            // The headers are stored until requested.
            rc = c.getResponseCode();
            if (rc != HttpConnection.HTTP_OK) {
                throw new IOException("HTTP response code: " + rc);
            }

            is = c.openInputStream();

            // Get the ContentType
            String type = c.getType();

            // Get the length and process the data
            int len = (int)c.getLength();
            if (len > 0) {
                rt = new RichTextField("TEST LENGTH"+len);
                int actual = 0;
                int bytesread = 0 ;
                byte[] data = new byte[len];
                while ((bytesread != len) && (actual != -1)) {
                   actual = is.read(data, bytesread, len - bytesread);
                   bytesread += actual;
                }
            } else {
                rt = new RichTextField("GREATER LENGTH"+len);
                int ch;
                while ((ch = is.read()) != -1) {

                }
            }
        } catch (ClassCastException e) {
            throw new IllegalArgumentException("Not an HTTP URL");
        } finally {
            if (is != null)
                is.close();
            if (c != null)
                c.close();
        }
    }

非常感谢您的帮助，谢谢，VKS

您需要运行 MDS-CS 模拟器才能使用黑莓模拟器连接到互联网
