			<tr>
				<td>Password:</td>
				<td><input type='password' name='j_password' />

				</td>
			</tr>
			<tr>
				<td colspan='2'><input name="reset" type="reset" />
				</td>
			</tr>
		</table>
 
	</form>
</body>
</html>

When i execute this http://localhost:8080/test/ "HTTP 404 error is displayed"

When i remove <filter> and <filter-mapping> it works fine but after i click on submit it displays http://localhost:8080/test/j_spring_security_check "HTTP 404 error is displayed"

I am not able to figure it out, any help will be greatly appreciated.
