地狱伙计们！我想用jee发送电子邮件。这是我使用的代码，但它不起作用。我使用的代码如下。

的index.html ` Java Mail

                <thead><tr> <td colspan="3" align="center">
                <b> Send Mail </b> </td> </tr> </thead>
                <tr> <td> To </td> <td> : </td>
                    <td> <input type="text" name="to" value="" /> </td>
                </tr>
                <tr>
                    <td> Subject </td> <td> : </td>
                    <td> <input type="text" name="subject" value="" /> </td>
                </tr>
                <tr>
                    <td> Message </td> <td> : </td>
                    <td> <textarea name="message" rows="8" cols="30">
                    </textarea></td>
                </tr>
                <tr>
                    <td colspan="3" align="center">
                    <input type="submit" value="Send Mail" />

                    <input type="reset" value="Reset" />
                    <td>
                </tr>

        </table>
    </form>
</body>
