Hi, Ernest,
Thanks for your answer. Do you mean I make all classes in the same package?
Is it OK, for example, if I use following structure:

How can I make it works?

Pls help.
Thanks

Hi,
I am building a multi-tiered application with Applet as the client and the architecture is as follows:
Applet<->Servlet<->EJB<->Database
At the Applet tier, there will be an Applet class together with some supporting classes, e.g.


User access the application through browser. My question is: do I need to install those supporting classes in user PCs? or The browser will automatically load all the supporting classes?
Pls help. Thanks a lot.

Friends,

Through my experience with Sun, there is much to improve for its service. Think that they could not open my submission jar file twice while the last successful one is just the same, nothing changed. There must be very messy in their backend which we do not really know but can see from many other's experience. Sun is killing itself by being like this.
Anyway, everything is over. It's time for me to take a breath.
Last, many thanks to Mark, Peter, Eugene and many others for your help. This is an excellent forum.

I think I have very good patience.
I just not understand why each time until so late then I was informed the problem (whether it's a real problem is not certain). This wouldn't happen if there is a sense of responsibility.
Do I need to instruct the assessors how to extract a jar file? They suppose to be java experts and have full knowledge to deal with such file. Also, no such requirement in SCJD instruction.
I'll give them one more time the submission, without any change, together with the extraction instruction though there is no point to do so.
I wish this bad experience will be over soon.
4 weeks no result. Feedback say SCJD submission jar file affected by Virus. Submit again immediately.
2 weeks more no result. Enquiry and feedback say assessor can't open the submission file. However, I've tested it on all platforms (Windows/Linux) and OK. Don't know what happen? Must I make it a self extraction jar file?
This is the efficiency of Sun. I faint...
Kathy

although I am the among the world's worst 'waiters', and would be going crazy myself.


How "worst"? Would like to know.
SunED is the major money-earn engine for Sun Microsystem and for a fair play, it should show higher efficieny.
My patience can last another 1 week at most...
Michael
Almost 4 weeks since I submitted everything for SCJD. No result yet.
Also noticed long time nobody post result in this forum. Sun slowing down?
Happy Chinese new year to all chinese friends!
Michael
I took the test on 6 Jan.. I heard somebody got the result less than 1 week.
Hi, guys,
Usually, how long it takes for sun to post the result? Is 10 days a long period?
Michael
Just tried to upload the assignment but not allowed. Do I need to inform Sun before upload? When must I take essay exam after I upload?
Please help. Thanks.
Michael
I've settled it using the same. BTW, how did you put the server side help? My server has no GUI and is stopped by Ctrl+C. I don't know if this is acceptable. Pls comment.
Thanks & Merry Christmas

HTMLEditorKit to display it (read-only) in an application window


In your submission, did you include this component together with all your own files?
I am thinking about javax.help package. However, since this package is not included in JDK and must be installed separately, it definitely needs to be included in the submission file, which I think may not be acceptable to this project. What's your opinion on using javax.help?
If don't use outside tool, seems there are only two simple choices:
1. Make a standalone HTML or TXT manual.
2. Make a text manual and use sth like JEditorPane to display it - thus make it online.
Can I go for one of them?
Pls guide. Thanks.

Michael
Peter, Thanks for your many helps.
I've just finished the design choice document, readme.txt, etc. I am going to submit the following in a jar file:
1) Original assignment jar file downloaded from Sun site;
2) All .java files for all packages;
3) All .class files in proper directories;
4) All javadoc files (*.html, *.css, etc);
5) designchoices.txt;
6) readme.txt.
Do point out if I miss something here.
In the assignment instruction, there is an item: user documentation (10 marks). What's this? Does it mean user manual, or more than that? Right now, I don't have a user manual nor a built-in help system. If it is necessary, shall I go for a manual or a help system? To build a help system, it requires components outside of the standard JDK package. Is this an offence?
Pls advice. Thanks.

Michael
I've revised my project based on the discussions obout this topic. Now, I need to justify all the choices I made. However, I am not very sure on some issues:
1) A client may stay connected throughout or may work in cyclic mode of connection-transaction-close. Both have drawbacks. For the former, it is for sure a nightmare to the limited capacity of RMI server if nobody drop connection. The latter requires a lot of reconnections and will soon become intolerable if you succeed one but fail all other. Which one shall use???
2) For local mode, is it really not necessary to implement lock/unlock? Or is it because the locking approach for network mode not applicable here? There are many posts about this but none fully conviced me.

Pls do point out any mistake, flaw and inelegance in my design. I am planning to submit it soon if you guys feel it is ready.
Many thanks...

Michael
