Hi,

I'm working with servlets and jsp. I'd like to get a virtual url. For example type www.eshop.com/product/XXYY and get info about a product XXYY.
The XXYY is stored in a database and shouldn't be in DD file.

Does DD file allow me to define a section where I would run a servlet which would decided if the URL is valid (after looking into a database).
Also it would be desirable to have this url visible in user's browser.

How can I achieve this?

Thanks,
Martin

Hi,
well, I'm not that beginner. I did a small project in Struts a year ago. I rafly know servlets, jsp and struts.

Now, I'd like to get more involved in J2EE and don't want to waste time with obsolete technologies...

I'll try to do something with java FX, it seems cool and jung technologie enough.

Thanks,
Martin

Hi,

I have just passed SCJD and would like to get knowledge on J2EE as well.
The question is which technology is "in" nowadays? I'd like to develop my e-shop and would like to use techniology which is not obsolete, at least not yet. There are too out there Struts, Spring, JSP, JSF, EJB, hybernate...

What book(s) would you recommend me to read?

Thanks a lot,
Martin

Hi, not really.

The problem is that my data are changing constantly and I need to know which data is useful(visible to user), then fetch it from my hardware and then call TableCellUpdated.

The trouble I am having is that I don't know what it is I want to fetch from data source.

If my data were static then JTable would do all I needed.

Maybe I want too much from java. It is after all, platform independent...

Basically, my data source is a piece of hardware connected throught a serial cable. This connection is very slow; it takes about 3 seconds to fetch current data which are constantly changing.

Now, there is a need to watch different resources through the same cable as well, so when you run two instances of my app then the refresh takes 6 second. Potencially, there is no limit of how many views on the resource there is going to be (within a reason).

So, I had an idea of refreshing just fields which are currently visible to speed everything up. After all, why waste resources when nobodu is going to see it.

I was interested in native windows. The real visibility for a user.
What is the diffucult way?

thanks,
Martin

Hi,

I have a JFrame and in it a JTable. I'd like to know if there is another window above mine and if so I'd like to know which cells in the jtable are actually visible on the screen.
is there a way how to figure this out?

Thanks,
Martin

Hi,

it is a bit difficult to understand you. Do you need to postpone your exam?
If so then you can reschedule your exam date on prometics site free of charge. I did it as well.

Cheers,
Martin

Thanks

I am happy for this result. It was a nice surprise after six week of waiting.
It motivated me to go for SCEA even though I am not convinced that it will be any useful (yet).

I wander what they didn't like. I expected a bit more comments.

If anybody needs my source code to get some inspiration, let me know.
I read SCJD Exam with J2SE 5, Second Edition (Expert's Voice in Java) and followed their ideas.
