解决方案
解决方案二：
楼主我也遇到这个问题了
解决方案三：
你页面的j_username这个元素肯定是这样写的<inputid="j_username"type="text"value="vvv">
driver.findElement(By.name("j_username"));其实就是调用以下的javascriptdocument.getElementsByName("j_username");
IE和firefox的javascript的引擎不一样，ie的场合找不到name的话会去找idfirefox就直接返回null了。所以把页面的id改成name就行了
解决方案四：
或者webdriver的代码改成WebElementusername=driver.findElement(By.id("j_username"));
