blocks|key|2747845|text|对于数据库连接，您需要了解JDBC是如何工作的，然后考虑学习构建在JDBC之上的Hibernate这样的框架(可以避免编写SQL)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2747846|对于前端，您需要选择一个服务引擎和工具包。你想写你自己的HTML吗？或者，您可能想使用GWT之类的东西来创建富UI？有很多web前端框架。|2747847|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

For database connectivity, you need to understand how JDBC works as a principle, and then consider learning a framework like Hibernate that is built on top of it (and lets you avoid writing SQL).

For the front-end, you need to pick a serving engine and toolkit. do you want to write your own HTML? Or perhaps you want to use something like GWT to create rich UIs? There are a lot of web front-end frameworks.

blocks|key|682339|text|问题是你想要构建什么样的应用程序。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|682340|我最近发现了一种很有前途的java+web应用开发的新方法。|682341|Play!+framework|offset|length|682342|这是一个易于学习，完整和快速的web应用程序框架，非常适合初学者。值得一看。|682343|entityMap|0|LINK|mutability|MUTABLE|url|http://www.playframework.org/documentation/1.1/home^0|0|0|0|F|0|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|S|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|T|8|@]|9|@$F|U|G|V|1|W]]|A|$]]|$1|H|3|I|5|6|7|X|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q]]]]

The question is what kind of application you are trying to build.

I've recently found a promising new approach for java web app development.

<a href="http://www.playframework.org/documentation/1.1/home" rel="nofollow">Play! framework</a>

It is a easy to learn, complete and fast web application framework which is ideal for beginners. It is worth to take a look on it.

You First Need To Learn Basic Of Html
then 

<pre><code> Servlet and Jsp
</code></pre>

servelet you use for controller 
and jsp for view

servlet is core part of java web development if you understand servlet deeply then you can stand another java web framwork and jsp easily

and jsp is very easy then servlet 
but servlet is very core part of web development in java

blocks|key|682311|text|就像一切都取决于。我当然会学习依赖注入器的知识(Spring，Guice)。如果你需要一个持久化框架(JDBC、JPA、Hibernate等)。这些都是web应用程序服务的基础。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|682312|对于客户端项目，HTML、CSS和javascript是关键。你可以用它们做的任何事情都应该可以在你使用的任何java+web框架中重新创建。|682313|作为一个web框架，我对Wicket非常满意，尤其是来自服务层开发的Wicket。不过，我听说过关于Tapestry、GWT和Spring+MVC的一些好消息。Struts2当然是一个可行的选择，尽管与其他成熟的框架相比已经过时了。当然，这在很大程度上取决于您的需求。|682314|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

As in everything it depends. I would certainly pick up a dependency injector knowledge (Spring, Guice). A persistence framework if you need one (JDBC, JPA, Hibernate, ...). These are all underpinnings of the web application services.

For client side items, HTML, CSS, and javascript are key. Anything you can do with these should be recreateable in any java web framework you use.

For a web framework, I have been exceptionally happy with Wicket, especially coming from service layer development. Although, I have heard good things about Tapestry, GWT, and Spring MVC. Struts2 is certainly a viable option although antiquated compared to other maturing frameworks. Then again a lot of this depends on what you need.

blocks|key|4351804|text|您可能希望选择一个web应用程序框架，如Tapestry、Struts、Google+Web+Toolkit+(GWT)或Java+Server+Faces，但在此之前，我将学习JavaServerPages/Servlet/Tag+Libraries，以便您有一个良好的基础来学习更复杂的框架。您甚至可能发现Java+Server+Pages足以满足您的需求(对我来说，通常也是如此)！|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4351805|正如另一位评论者提到的，理解JDBC+(可能使用Hibernate)对于数据持久化非常重要。Spring也变得非常流行(也是雇主所希望的技能)，用于在幕后管理对象，特别是在web应用程序中。|4351806|Netbeans和Eclipse都非常适合于编写web应用程序以及在编写代码时对其进行测试。|4351807|但是，如果这听起来很复杂，只需从Java+Server+Pages和Servlet开始，然后从它们开始！|4351808|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|L|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|M|8|@]|9|@]|A|$]]|$1|H|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|I|$]]

You would probably want to choose a web application framework such as Tapestry, Struts, Google Web Toolkit (GWT) or Java Server Faces, but even before doing that, I would learn about JavaServerPages/Servlets/Tag Libraries so that you have a good foundation for learning the more complicated frameworks. You might even find that Java Server Pages is enough to satisfy your needs (and for me, they often are)!

As the another commenter mentioned, JDBC (possibly using Hibernate) is important to understand for data persistence. Spring is also becoming very popular (and a skill desired by employers) for managing objects behind-the-scenes, particularly in web applications.

Netbeans and Eclipse are both well-suited to writing web applications and for testing them as you write the code.

But if this sounds complicated, just start with Java Server Pages and Servlets and go from there!

blocks|key|2748017|text|我建议你在没有任何框架的情况下开始开发。从核心Servlets和JSP开始。一些超文本标记语言，CSS和JavaScript将是必要的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2748018|以下是您需要的开放源码内容列表|2748019|服务器-+Apache+Tomcat+5.0+%2B(首选)|2748020|API+-+JSP+(主要是Servlet和J2EE。还有一些JDBC。)|2748021|网页技术-+HTML，CSS，JavaScript+(如果你可以学习，Ajax将会很有趣，它很容易)|2748022|浏览器-+7%2B+7%2B、Chrome、Firefox等。|2748023|开发环境-+Eclipse+SDK+for+Java+EE+(您将获得一个集成的Tomcat+)|2748024|设计模式-尝试使用MVC。|2748025|这应该足够让你上手了。|2748026|entityMap^0|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|U|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|W|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|X|8|@]|9|@]|A|$]]|$1|J|3|K|5|6|7|Y|8|@]|9|@]|A|$]]|$1|L|3|M|5|6|7|Z|8|@]|9|@]|A|$]]|$1|N|3|O|5|6|7|10|8|@]|9|@]|A|$]]|$1|P|3|Q|5|6|7|11|8|@]|9|@]|A|$]]|$1|R|3|-4|5|6|7|12|8|@]|9|@]|A|$]]]|S|$]]

I suggest you start developing without any framework. Start with Core Servlets and JSP. A bit of HTML, CSS and JavaScript will be needed. 
Following is the list of open source stuff you will need

Server - Apache Tomcat 5.0 + (Preferred)

API - J2EE API (Mainly Servlets and JSP. Also some JDBC.)

Web Technologies - HTML, CSS, JavaScript (Ajax will be fun if you could learn, it's easy)

Browser - Internet Explorer 7+, Chrome, Firefox etc.

Development Environment - Eclipse SDK for Java EE (You will get an integrated Tomcat with this)

Design Pattern - Try using MVC.

This should be good enough to get you going.

blocks|key|682572|text|如果您了解Java和OOP的基础知识，那么您就走在了前面。我对可用的工具和框架的看法是，它们会驱使您开发cookie+cutter软件，并且最好能够设计您自己的对象。如果JDK标准对初学者来说很重要，那么您需要的大多数东西都已经被JDK标准所吸收。如果它不重要，为什么你要花时间去学习这些东西呢？|type|unstyled|depth|inlineStyleRanges|entityRanges|data|682573|首先，让以下各项正常工作：(1)+Apache服务器(2)默认端口上的tomcat+servlet引擎(3)默认端口上的数据库引擎|682574|第二阶段：(4)通过tomcat生成简单的HTML，在几个浏览器上查看(5)建立servlet-DB通信机制(6)将DB查询结果放到servlet生成的HTML上|682575|最终设置：(7)设计/测试servlet中的并发/线程和业务逻辑(8)设计应用程序所需的数据库表/模式(9)设置apache和tomcat之间的连接器(10)决定应用程序的GUI。对于更高的安全性需求，请使用applet并学习使用加密对象的applet-servlet通信|682576|这应该会让任何人忙上几个月。问候，-+M.S.|682577|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

If you undestand the basics of Java and OOP, you are way ahead. My view on the available tools and frameworks is that they drive you towards developing cookie cutter software, and it is better to be able to design your own objects. Most of the stuff you need are already assimilated in the JDK standard, if it is important for a starter. If it is not important, why would you want to spend time learning those things?

To start with, get the following working:
(1) Apache server
(2) A tomcat servlet engine on its default port
(3) Database engine on its default port

Secondary stage:
(4) Generate simple HTML through tomcat, view it on a few browsers
(5) Establish servlet-DB communication mechanism
(6) Put DB query results on the HTML that your servlet is generating

Towards final set up:
(7) Design/test the concurrency/threading and business logic in your servlet
(8) Design the database tables/schemas required for your apps
(9) Set up connectors between apache and tomcat
(10) Decide on the GUI for your application. For higher security needs, use applets and learn applet-servlet communication using encrypted objects

That ought to keep anyone busy for a few months. Regards, - M.S.

I am new to Java web development (but not new to Java/OOPs). I am looking forward to developing web applications using Java after mastering it. Please let me know what are the things I should start learning to develop web applications using a database in backend ?

thanks
