If you're going to use ExtJS anyway, have you considered using ExtGWT instead? That'll give you much better Java integration.

blocks|key|845554|text|我的团队在过去也使用Struts。我们已经前进了，正在使用DWR，我们喜欢它。我们在DWR和Ext方面的经验非常好。如此多的锅炉板代码，无论是在Java端的DWR代码，还是在JavaScript端的Ext代码，都已经减少了。还有一个ExtJsWithDwr项目可以帮助集成两者：http://github.com/BigLep/ExtJsWithDwr。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|845555|entityMap|0|LINK|mutability|MUTABLE|url|http://github.com/BigLep/ExtJsWithDwr^0|3V|11|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

My team also was using using Struts in the past. We have moved forward and are using DWR, and we love it. Our experience with DWR and Ext has been great. So much boiler plate code, both with DWR on the Java end, and Ext on the JavaScript end, has been reduced. There is also a ExtJsWithDwr project to help with integrating the two: <a href="http://github.com/BigLep/ExtJsWithDwr" rel="nofollow noreferrer">http://github.com/BigLep/ExtJsWithDwr</a>.

blocks|key|2371577|text|ExtGWT如果您愿意使用GWT，或者我推荐Metro(或任何Java+RESTful实现-+JSR+311)+%2B+ExtJS，那么它的工作效果很好。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2371578|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

ExtGWT if you are willing to go with GWT, or I would recommend Metro(or any Java RESTful implementation - JSR 311) + ExtJS, it works great.

blocks|key|954457|text|我们一直在使用雷斯特，取得了很好的成功，而且它可以应用于不是100%25+RESTful的应用程序(我们有一些领域比较轻率)。这不是一个完整的解决方案，但它与其他技术有着良好的集成。例如，我们使用Restlet对Apache模板生成器的支持来生成XHTML/+FreeMarker页面。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|954458|我们生成的页面使用jQuery，而ExtJS应该同样工作得很好。雷斯特莱特也有一个GWT模块。|954459|entityMap|0|LINK|mutability|MUTABLE|url|http://www.restlet.org/|1|http://jquery.com/|2|http://wiki.restlet.org/docs_1.1/13-restlet/144-restlet.html^0|7|3|0|0|9|6|1|15|5|2|0^^$0|@$1|2|3|4|5|6|7|R|8|@]|9|@$A|S|B|T|1|U]]|C|$]]|$1|D|3|E|5|6|7|V|8|@]|9|@$A|W|B|X|1|Y]|$A|Z|B|10|1|11]]|C|$]]|$1|F|3|-4|5|6|7|12|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]|N|$5|I|J|K|C|$L|O]]|P|$5|I|J|K|C|$L|Q]]]]

We've been using <a href="http://www.restlet.org" rel="nofollow noreferrer">Restlet</a> with good success, and it can be used on applications that aren't 100% RESTful (we've got areas where we're a bit cavalier). It's not a full solution, but it comes with decent integrations to other technologies. For instance we generate our XHTML/CSS pages using Restlet's support for the Apache FreeMarker template generator. 

Our generated pages happen use <a href="http://jquery.com/" rel="nofollow noreferrer">jQuery</a>, and ExtJS ought to work equally well. Restlet has a <a href="http://wiki.restlet.org/docs_1.1/13-restlet/144-restlet.html" rel="nofollow noreferrer">GWT module</a> too.

blocks|key|954468|text|还请看一下泽西岛。它是JAX+(JSR+311)的一个非常有用的实现，很容易集成到像您这样的现有项目中。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|954469|如果我是您，我将创建一个单独的包(甚至是EAR/WAR)，这些类只与您现有的EJB对话，并公开为ExtJS可以与之通信的REST服务。|954470|entityMap|0|LINK|mutability|MUTABLE|url|http://jersey.java.net/^0|5|3|0|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@$A|O|B|P|1|Q]]|C|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|C|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|C|$]]]|G|$H|$5|I|J|K|C|$L|M]]]]

Also have a look at <a href="http://jersey.java.net/" rel="nofollow noreferrer">Jersey</a>. It's a very useful implementation of JAX-RS (JSR 311) that is easy to integrate into an existing project like yours.

If I were you I'd create a separate package (or even EAR/WAR) with classes that just talked to your existing EJBs and were exposed as REST services that ExtJS can communicate with.

blocks|key|845472|text|我一直在使用类似的项目J吸收，它非常类似于DWR，但符合JSON。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|845473|entityMap|0|LINK|mutability|MUTABLE|url|http://jabsorb.org/^0|B|3|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

I've been using for similiar project <a href="http://jabsorb.org/" rel="nofollow noreferrer">jabsorb</a>, which is very similiar to DWR, but conforms to JSON-RPC.

blocks|key|845519|text|您可能需要查看Myna+(http://mynajs.org)。这是一个服务器端JavaScript应用程序平台，部署为J2EE+war文件。作为服务器端的JavaScript，它与Ext集成得很好.实际上，所有内部管理UI都是用Ext编写的。Myna有几个您可能会发现有用的特性：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|845520|基于Web的管理员应用程序。不需要编辑XML文件|unordered-list-item|845521|基于Web的数据库管理员。可以运行查询、创建/编辑/删除表，以及从GUI生成Myna和SQL代码|845522|集中式数据资源管理和数据库连接池|845523|支持SOAP、XML、JSON和MYNA-JSON的Web类，Ext.Direct即将到来！|845524|支持处理PUT、POST、GET和DELETE+HTTP请求|845525|支持在JavaScript代码中加载POJO(通过Rhino)|845526|运行时对象关系映射。当数据库表更改时，不需要编辑XML文件或重新编译类|845527|Javascript预处理器支持带有隐式准备语句和类型化参数的多行SQL查询。|845528|查询支持分页和返回总行，这在Ext的网格和PagingToolbar中运行得很好

You might want to check out Myna (<a href="http://mynajs.org" rel="nofollow noreferrer">http://mynajs.org</a>). This is a Server-Side JavaScript application platform that is deployed as a J2EE war file. Being server-side JavaScript it integrates well with Ext. In fact, all the internal management UI is written in Ext. Myna has several features you may find useful:

<ul>
<li>Web-based adminstrator application.
No need to edit XML files</li>
<li>Web-based Database adminstrator. Can
run queries, create/edit/drop tables,
and generate Myna and SQL code from
GUI</li>
<li>Centralized Datasource management and
pooling DB connections</li>
<li>A Web Service class that supports SOAP, XML-RPC, JSON-RPC, and MYNA-JSON with Ext.Direct
coming soon!</li>
<li>Support for handling PUT,POST,GET,
and DELETE HTTP requests</li>
<li>Support for loading POJO's in
your JavaScript code (Via Rhino)</li>
<li>Runtime Object Relatinal Mapping. No need to edit XML files or recompile classes when the database tables change</li>
<li>Javascript preprocessor supports
multi-line SQL queries with implicit
prepared statements and typed parameters</li>
<li>Queries support paging and returning
total rows, which works well with
Ext's grids and PagingToolbar

Full Disclosure: I'm the primary developer for Myna</li>
</ul>

We are plannnig to upgrade the UI framework for our 6-8 year old application written using Struts/JSP/EJB to ExtJS. Just curious as to what is the most popular Java technology on the server people have been using. We were looking into several alternatives like

<ol>
<li>DWR</li>
<li>RestEasy</li>
<li>Restlet</li>
<li>Struts-Json</li>
</ol>

We are diving more towards using DWR but just wanted to know if the programming community has some food for thought on this.

For backward compatiblity reasons the migration will happen incrementally and during that period we will try to make ExtJS coexist with the old Web1.0 style pages. We are not changing anything on the business tier but just the web tier will change from JSP to ExtJs pages.
