Getting resourcess from server-webstart issue

Networking & Multiplayer
#1

I need to develop a banner rotation system for our game. It is webstart enabled game…so i guess thats all there is to it.
Game has a server to which clients connect to get game data… I need to somehow make a system which can download images/strings to clients machine, store it there and later display(i know the latter ;)).

So if any1 of u has done something simmilar ever, or has idea what to use to implement this in efficient way…all clues and hints are welcome.
Tnx.

P.S If u want to check it out it is in my sig :wink:

You can get images/stuff through the URLConnection class very easy - that’s what I use.

#3

Looks promising, but does it require web server on the server side? We only have our game server up and running there…

#4

Yes - but you have a web site anyway (http://www.b92.net/sport/mundijal2006/arena.php). You upload images to the web site (with e.g. FTP) and then access it simply through http://www.b92.net/sport/mundijal2006/images/Image1.jpg with URLConnection.

#5

Sure…but our game server is on the other machine…I ll look into the code then.

One more question :)-what if there was no web server at all ? :slight_smile:

#6

doesn’t need to be on the same machine.

If there is no web server - I assume you have a game server setup - then just send the image through the game server to the client.

#7

OK, thats all clear…but since client is webstarted, how to store image? Muffins? Anything else more convenient? :slight_smile:

#8

I tend to store the images in a .jar file. So, when you start your game through web start, the images/resources.jar is downloaded automatically too. Just add it to the list of required .jar files. Accessing the images/resources in the .jar is easy.

#9

Sure storing in jar is the most easier…but then i have to change the jnlp right? And when it gets changed, then all previously downloaded files will have to be downloaded again…i guess :)-i dont want that :slight_smile:

#10

Java tends to cache .jar files, so you will only download new/updated jar files. ;D

#11

That is correct, but i think that when jnlp is changed, all will get installed again as another app i think…correct me if i m wrong.

#12

ARgh argh argh. Stupid forums. Sorry, apparently I clicked modify instead of Quote. Sorry, sorry, sorry!

#13

OK: you are wrong :). As stated previously (and in fact one of the main points of webstart) it only downloads the files that have changed.

EDIT: ever wonderd why webstarts include the href to the jnlp? its so that you can completely change the jnlp name / location but webstart will know its the same app (have tried this many times, it works)

#14

:slight_smile: Tnx for the info. I guess that i will stick to the jars then…though i still think that they arent that convinient for banner system…there might be big number of jars…could create a mess maybe…

#15

of course they aren’t convinient… use web server and load images from them, why are you rejecting this solution?

#16

Yes, the images should be on the server and you use URLConnection to access them …

#17

Hehe…on contrary…i want this solution. I just want to know what is the best way to store thos images on the client-dont want to dwnld al over again. Are muffins good choice?Any other?Dont remember client is webstart app.

#18

ok then, just save the image after you download it … I’m sure you already thought of that… good luck with your sponsors

#19

Sure i will save it :stuck_out_tongue:

But whats the most convenient way? Muffins?

#20

I’m not sure of what do you mean by Muffins ? I only know Jars…
