<Content>我觉得，javabean可以看做是有固定接口格式的servlet，jsp比较适合显示逻辑的设计，至于商务逻辑javabean和servlet都是不错的选择</Content>

<Content>struts的特点是：
1、以jsp自定义标记代替jsp页中的java代码，使jsp页看上去更象html，表现和
&#32;&#32;&#32;逻辑分离
2、符合mvc模式:m是ActionForm,由用户提交的表单数据生成，c是
&#32;&#32;&#32;ActionServlet和Action，v是jsp

流程如下：
1、用户提交表单数据
2、actionservlet根据struts-config.xml中的配置信息，生成一个actionform,
&#32;&#32;&#32;该actionform有一些getXx、setXx方法和几个validate，actionservlet会
&#32;&#32;&#32;自动调用这些方法；
3、如果validate方法返回actionerrors，则用户会回到提交前的页面，错误信
&#32;&#32;息及提交的数据会显示在该表单中，便于用户修改后再次提交
4、如果validate返回null，则运行对应的action，进行数据库操作等等。

validate中主要进行数据验证，如格式、类型、长度、是否填写等等</Content>

<Content>我可以插拨一下吗：

servlet和bean的运行机理是一样的吗？
例如是否都是第一次之后一直运行在内存中。释放时间等等</Content>

使用自定义代码的jsp页面，是否需要想servlet一样编译一下，还是访问时再编译。</Content>
