Hi all,
How can I display an xml file with JFC? And the look and feel is best to be the same as what would be shown by internet explorer. The expansion functionality can be omitted.
Is there any simple method rather than writing an XSL?
Thanks.

Hi,
Thanks.
I wish I can find a job and I plan to take a part-time MS after graduation. And a lot more plans... But all depends on whether I can get a job. Hope I am lucky enough.

Hi,
Can anyone give me a help please?
I am very very hesitating about whether I should continue getting certified. I posted a question several weeks ago, but I still cannot make a decision now. Is it really worth?
Now I am an undergraduate and have to find a job next year. What should I do?
Thanks.

Hi Samual:
I think you are going the wrong way. You are making it more and more complex but further and further away from the standard way of implementing a lock manager.
Actually you just need a monitor to control the mutual exclusive access to each record in the database. And in this project, LockManager is the monitor.
So, first, you cannot use

synchronised(hashMap)

since that is equivalent to lock the entire database, which is not desired. Second, LockManager must be a singleton ( I don't know if you used the singleton pattern, but if you use it, then follow the rest points I stated below). Third, make lock and unlock method synchronized instead of synchronizing on objects. Then, still use wait and notifyall pairs to implement the semaphore.

Hi,

Did you send any email message to SunEd after you took essay exam?

Yes, I did. After about one week I emailed them. They were very friendly. They told me the exact date when my assignment and essay were sent to the assessor and they asked me to wait.

Can you tell me what you mean by different users and also how many pages your user docs were?

From what I understood, I wrote three user docs:
1, online help in JEditorPane: targeted at the travel agent and used to teach them how to use the searching and booking facilities. (less than 1 page)
2, user doc for client, targeted at the technicians in charge of installing and maintaining the client side software ( no design choices included) ( less than 2 pages )
3, user doc for server, which is similar to 2, but targeted at technicians for server. (less than 2 pages)

Hi,
I don't think it is necessary to add in so many complexities. Just keep it simple. An online is help in JEditorPane should be very very brief and simple html even without any links can do, which should be graded as part of GUI. And seperate user docs should be provided. They are targeted at different users.

Hi Sam:
If you mean the javadoc, I didn't do any javadoc comments for the fields. And I didn't use a lot of inline comments either. My comments are all very brief. I only provided those important descriptions for the LockManager and CriteriaFind actually. Few comments for other classes besides javadoc.

Hi,
I got my result exactly two weeks after I took the essay exam.

Hi, Mike:
I should express my special appreciation to you. You helped me a lot. You cleared me many doubts. And you were always so patient and kind. Thanks.

Hi all,
I am an undergraduate now in my final year. I've passed SCJP, and SCJD. I am doing computer engineering degree. In order to get a good job in IT, hopefully in Java area, should I continue with SCEA? Or should I stop here, and work harder on my course subject in order to publish a paper, or something like that?
Thanks.

Hi,
I used the java coding conventions that I found in sun's website. So, I think it should not be problem. But I didn't use any executable jar files, and I had two copies of db.db, which may be the reasons. I don't know. Anyway, for those who haven't submitted their projects, you'd better not follow the way I did it.

Hi all,
Just get the result from sun. I am so excited although the score is not perfect. The details are:
General Considerations(maximum = 58): 48 Documentation(maximum = 20): 20 GUI(maximum = 24): 24 Server(maximum = 53): 53
Actually I am a little curious why they deduct 10 points for the general considerations, but offering me full marks for others. Maybe what I didn't do excellent is the way of packaging and deploying the program.
And thank those guys who helped me a lot very much, especially Mark, and Mike. And any questions from the forum are welcomed.

Hi all,
Now I am designing an infrastructure for PDA application. The basic use case is that the employees need to communicate with the manager about the sales information. So, the employees should be able to both send and receive information to/from the server. How can I do it?
I don't think it should be a Servlet based achitecture, since then the client won't be able to be informed by the manager of any urgent things at any time he wants to. So, for a active two-way communication, I am thinking whether RMI can do this. Does anyone know whether i could invoke a remote object on the PDA from a server?
Thanks.

Hi,
Then should I continue taking the java certifications? Or, can I just do some opensource projects, since the exam cost is really high.
Thanks.

Hi all,
I am currently a final year student of Computer Engineering degree. I am planning for my graduate career. Now I have several plans:
1. go for a full-time master degree by research
2. go to find a job
3. find a job and do a master degree by part-time course work
I've got the SCJP, and the SCJD is being graded. And I think I will get a good honours degree. Now I can not make a decision whether I should pursue further java certifications, since I am not sure whether a certifcate could add value on my resume as a fresh graduate. And if I continue to do a mater degree by research, by the time I finish it, will all my certificates become of no value at all? And is a master by course work valuable?
Any comments please share with me.
Thanks.
