又看到国人在Java方面的一个壮举。

这个sjep我感觉定位很模糊,你说它类似Jboss这样的appliaction server吧,不象;你说它是一个EJB组件软件吧,看不出它提供了除EJB以外更多的功能层。

或许它提供了EJB外的安全功能,可是JAAS+EJB的权限控制,J2EE规范早已经有了,Jboss这样的Server也能实现EJB的方法级别的安全控制。

或许它屏蔽了许多单个Server,可以让很多Server运行起来象一个Server,但是这属于J2EE的Cluster技术,Jboss 或weblogic本身已经实现了这样集群服务。

其勇气和精神可贵,可是在如今世界上Java Server端正聚焦O/R Map或面向特征等最前沿先进技术的推进开发中时,sjep自诩为国际原始创新性,不知是否又范了国人闭门造车的老毛病。

呵呵~~ 你好有空啊,这里看看,那里看看...

我在写一个基于 Jato Web Application Framework 的 RAD.
主要是为自己写的,以前写了个 1.0 版,也是为自己写的。用了几个月,感觉还是少了些什么,这次准备加些 feature 上去。

对了,我现在最需要的是一个小工具,最好是可视化的,可以从数据库中选取需要查询的表,以及表中的字段,可以设置一些参数,如 orderby groupby 等,最后可以自动生成一些 JavaBean 来操作这些表。就像 JBuilder 8 中的DataModuler,只可惜 DataModuler 生成的代码是与 JBuilder bind 在一起的,我需要的是使用JDBC 的JavaBean.

不知道 Banq 以及各位有没有见过这样的东东呢?

有的,不过好像是收费的,免费的目前没见过。算了用Jbuilder的CMP,也是可视化开发 不错的。呵呵

First to Iceant,
I just reply to your post about DAO gen in separate thread, try Velocity, actually I just finished a generator myself.
you use XML to model the object, can have whereclause, relationship, and some business rules( formula, constraint) stuff, there get translated into java object with simple getter/setter, constraint, relationship enforcement.
I use Velocity. I did found a tool that can gen object from database schema directly( I can find it for you if you care), but I need add lots of things before gen.

BTW, do you guys have yahoo messager?

To Banq,
The title here led me to that website, I like his idea "Simple", that's what exactly My Topas trying to solve with J2EE.
Yes, I have the same confusion about his technology, too me, it has some cute stuff but maybe over-stated to my opinion.

I think he is using some kind reflection to hook client to his sejbObject which is not exposed as EJB, which is not new( JMX, Proxy all do the same thing). I have little doubt about its performance under heavy load. But the idea is same as Topas, I use a GenericFacade Bean to brigde the client and server.

He definitely see the problem of declaring security in EJB, so he push all security control into one file or database, that's practical approach, in fact I did the same thing in topas

I am not impressived with his distribution, in topas I call it "Service routing", it's not a first class feature, in certain cases, it can be very useful, but generally its useless or hurt perofrmance if use it blindly.


In summary, its product has some nice things and cover a lot of ground, should we invite him into our discussion? I really want to shot him a emal.
