我正试图用Dephi5作客户端，JBuilder3作服务端，用CORBA连接它们，并
想用JDBC连接 Access数据库，不知其可行性，欢迎讨论！
另外，现在JBuilder的资料很少，提供英文/中文资料者另外给分，
这300分用于“灌水”。
CJ:我看你也在找，不知进展如何？
y9y:听说你有JB的企业版，那一定有Pdf的DG吧，开个价，可
又是笔好生意噢！；-）

JBuilder3做服务器还要用Delphi做客户端……用浏览器做客户端不好吗？

Java速度慢,而且我要用delphi完成套打,界面定制,公文包,等等,
所以还是delphi强一些.

用jbuilder开发? 你的机器一定配置很高, 俄的p3 500上用它都慢的.
我觉得你可以用applet/serverlet做,没必要把程序搞的向多国部队一样的.

上面的大侠谈的都非常好,serverlet是什么?
我是临时抱佛脚学的JAVA,请多多指点.
我用Jb主要考虑希望它能和D5的CORBAConnection控件连上
不知可行与否?

Crane: 歪就歪受宠若惊的看到自己的名字排在孙老师、CJ后面，这……
可真是惭愧，那好东西到了我的手里却真的没派上什么用处，我只是简单
的学了一下JAVA，但用JBUILDER的实际开发还一点都没有，所以，你说的
“听说你有JB的企业版，那一定有Pdf的DG吧”，不明白这DG是什么。
ServerLet就是在Server端运行的程序吧，那性质好象有点象Corba的Server
在JAVA里有它的一堆Class，什么Stub之类的，（好象如此……惭愧惭愧。硬着
头皮说两句，骗两分花花）
To Yutoo:加大内存吧，我看BORLAND公司的演示会，他们演示的程序RUN在350多
M内存上，效果还不错。

youtoo:jbuilder 运行环境必须在128m Ram以上,否则很慢,cpu像我k6266就好!
Crane:jbuilder的文档都读不完,还要别的?不过你可以借一本<delphi4技术内幕>
(就是133RMB的那本),里面有一部分讲了制作java corba server,可以看看.

to y9y:
谢谢捧场,DG就是develop Guide,delphi5光盘上有DG和QS两个文件,一看遍知.
Java是否在Linux /Novell/BSD系统上会快一些? ServerLet好像不完全是你理
解的那个意思.
to ahfei:
我要的就是文档,JB3是从网上DOWN下来的,好像没有.

就请发到hebusiness@sina.com.我会另开题给你分.

1.About Tools: VisualAge. If your machine is not good enough, Jbuilder is the least choice. It will save yout time just pay a little money! Vage:256M+P366 Jbuilder 64M+P266 /NT
2:About architecture: Why use D5 on Client? It is a fat Client? Try this pure solution:
DB--Java APP(RMI/CORBA/SOCKET---Servlet/JSP---HTML/Applet. It will be easy. If it is a real project. Try to be simple and work. If it is a trial project, use D%+CORBA is a good chance to learn a lot!
3:JB2 ot JDeveloper 's On-line help is good enoutgh.do
not waste time to get others!
4:If just for fun, try Vage+EJB. Chanllenges!
5:Servlet is easlier than you can image. It like ISAPI/CGI. Jsp>>>>>>>>>>>>>>>>>= ASP.
6rint: I have no expr on utilizing Java on print. But, if using D5, why not all D5 plus CORBA interface in cse further use? Delphi is always ALIVE!

xiaoxiaoxue:不管怎么说先谢谢你！
yaojian:
1。我现在的试验机：IBM双PIII550+500M+26G应该够了吧？
2。我主要是要保证客户端的操作性，而且还要打印，界面可定制，套打等等
一切都有赖于Delphi.我现在就是要用JB作CORBA服务器。
3.其Help确实很好，但是我不太明白的是其编程环境如何生成一个CORBAServer
再象delphi那样使用datasetprovider,Tqery等等。
4.不是为了玩，跨平台确实是实用的技术。

Actually I use JB.
About CORBA, I implement once by utilizing pure Java and transfer to RMI after I find it efficiently.
It is not simply same as datasetprovider. Once I look through the D5 help on distribution system, Ido
not find delphi can use CORBA like this way, unless the CORBA server is developed by Delphi? This question beats me.
Why not try this:
A table: Studentent ID, Name
CORBA server , e.g.:
String getStudentName(ID, Name)
client calls it to get a string? Of course, it will make a lot of functions, but if you want to implment the Deta or MIDAS kind in Delphi, you must read Delphido
cument for times instead of spending time on Java. In this project, Client determine the Server.

yaojian：
非常感谢，Jbuilder既然是Inprise 开发的，就应该和其他产品能够集成。
所以，我是想看看delphi的客户端能不能得到jb的DatasetProvider的接口
如果按你的方法，好像不同Jbuilder也可以了。
大家接着聊！

JBuilder has nothing todo
with D5. But Ido
not know whether Inprise has open the Delta structure?
If you want to develope one Jbuilder Delta, you will get rich quickly. Actually, Inprise hasdo
ne a lot so you can gain convinience from MIDAS. And you should think about the price of MIDAS license!
There is no shortcut if you want to reuse your Java interface, I remember there is a XMLBroker to pass data, maybe you can try it. But Ido
think you will be upset after you go through these. If you insist on create a reusable component about these project, I think there are two ways, you develop one or you have to wait for Inprise. And these two ways seem to be dispairing.
I have no idea on JBeans, maybe you can get some from it.
If I developed this project, I would adopt two ways:
Pure Java: Java can make it on the GUI, if you have enough patience.
By XML: developed an XML Server to package the data and transfer to client. Both on server and on client will you find the finished API.
Good luck!

完全没有问题。如果你用corba的话，你大可以去英文yahoo!，我已经查了很久了。
