<0> is there already any cl*** in the java library to get the CPU speed and type of processor and stuff ?
<1> Has anyone here successfully made SQL database queries from a java applet?
<1> If so, I'd like to talk to you
<0> i have from java cl***...not with an applet though
<0> basic console based
<1> hmmm
<1> would there be much of a difference?
<2> you can't make SQL queries from an applet.
<1> Zenethian: why not
<0> i dunno applets
<2> Well for one, you don't want to architect your software that way
<2> You'll want to create a web service to do your database layer for you
<2> and only have the applet make calls to that web service
<1> such as...?
<2> what do you mean such as?
<1> an example of this web service
<2> well, you have to write it
<2> so whatever you think you need to accomplish with a SQL call.
<2> like you could have one called AddThreePies
<2> or something
<2> or AddPies and take a parameter, count.
<1> it's going to be for a game...
<2> doing SQL through an applet exposes a ton of ways to totally hack your server
<2> Plus I don't even think you can do it with the security manager that applets have to run in.
<2> So you need to build yourself an exposed API of things that you need your applet to be able to do
<1> so there will be units on screen, each unit will have x and y coordinates that will have to be checked/updated with the SQL server
<2> ok, so make a web service to do that instead
<2> CheckUnitXYCoords
<2> and in that web service, then you do the SQL interactions.
<2> web services run on your server, not in the client
<1> yeah
<1> I don't have physical access to run programs on my server though
<2> Um, web services don't run as programs, they run in your web server
<2> Really, so many things on the web ARE web services and you don't really even realize it
<2> except yours won't be returning html, it'll return some other data format. plaintext, xml, whatever you choose.
<1> so wait
<1> would I make like... a php page that the java program checks/
<2> You can do it in PHP if you like
<1> how would you, personally, do this?
<2> especially since you don't have the ability to run separate programs on your webhost, that would be a good way to do it. You could use XML-RPC or make up your own way to call it
<1> yeah
<1> XML-RPC?
<2> Well, if I had a server like yours, this is the best way, IMO
<1> XML remote procedure call?
<2> If I had full control, I'd make it client-server and keep a persistant connection between them with a custom data protocol.
<2> yeah
<1> yeah, that's what I'd do too if I had full control
<1> but I run dialup.
<1> it'd be quite bogged down
<1> are there any tutorials you know of for the procedure I'm looking at?
<2> I'm sure there are lots.
<2> XML-RPC is pretty popular in PHP and Java
<2> http://webservices.xml.com/pub/a/ws/2004/03/24/phpws.html
<0> how do i connect java and mysql server? is there any tutorials for that
<2> edited: use JDBC
<0> i know..but is there any tutorials for that
<2> Yes, lots.
<0> right now im just trying to write a simple java program which will list the tables in a database and stuff
<0> then im gonna add some more stuff
<2> Cool
<0> its been long time i havent touched java
<1> allrighty, zene
<2> =)
<1> another one for ya
<1> http://www.seldemon.com/testmap.php
<1> that's basically what the map's going to look like. However!
<1> not really.
<1> In battletech, there are different types of terrain and different elevations
<1> how would you personally go about making a static map, which portions of it will be loaded
<2> what do you mean static?
<1> the map will be around 1000x1000 hexes, but you'll obviously only be able to see about 30x30 at a time
<2> yeah
<1> as in, the map should be stored to some file
<2> nah
<2> store the map as data
<2> not as a big graphic file
<2> and render it
<1> yeah
<1> that's what I meant, it'll be stored like
<1> 0000010011134200013
<2> ok
<1> 1381805324274724
<1> rows and columns
<2> sure, if you want to do it that way
<1> that designate terrain type, then another data file that designates elevation
<2> I was thinking of maybe a more relational model
<2> so you can have easy lookups
<1> as in?
<2> a four column database table. X, Y, TerrainType, Elevation
<0> first ill have to add JDBC driver to my library right?
<1> I didn't even think to do it that way. lol
<0> i use netbeans
<2> edited: I guess, yeah.
<2> Memphetic: plus then it is easy to add new information as well.
<1> this table will have 1,000,000 rows :-P
<2> it's ok, they're designed for that kinda thing.
<1> any suggestions for ways to actually enter the data?
<2> heh
<2> Manually? :-/
<1> yeah
<2> Or you can write map editing software.
<1> figured :)
<2> likely manually to start. :D
<1> around 98435 I'll probably get fed up
<2> well, you can always populate the whole world with water
<1> yeah!
<2> to make all 1,000,000 hexes programmatically the same, and then fill in the ones you need.
<1> forget mechs and tanks. It's naval.
<2> or fill it all with land.
<2> whatever the most common type of space is gonna be used =)
<1> there really isn't one...
<2> well then choose one.
<2> hehehe
<2> or
<2> make a "blank" hex type
<2> just to get data in the database
<2> though I'd personally start out with a real type of hex
<1> yeah that would make more sense
<2> so that you can build the map AFTER the game mechanics are ready.
<1> maybe I'll just make a map editor that generates SQL code
<1> then paste it into phpMyAdmin
<2> and in the mean time, you have something of a map to work with
<2> yeah, that could be ugly, but work.
<2> Or you can write an applet that does it
<1> besides. it's gonna take me awhile to find someone to make a 1000x1000 map anyway.
<2> click on a hex, change it's properties, use a web service to update the hex
<0> does JDBC already come with the JDK?
<2> it should, yes.
<2> you just need the mysql jdbc driver
<0> get that from mysql.org?
<2> likely yeah
<0> so ill have to add that jar file into my netbeans
<1> Zene
<1> didn't you just get done telling me that that was a bad idea? :-P
<2> ?
<2> He's not doing it in an applet.
<2> there's nothing wrong with using mysql in java
<2> but you don't do it across an internet connection. :P and you most certainly don't do it in an applet.
<2> heh
<0> Cl***.forName("sun.jdbc.odbc.JdbcOdbcDriver");
<0> will this do it for properties?
<1> okay, zene.
<1> So basically
<1> I'm gonna be making a PHP page that creates an XML tree with data on every unit to be displayed
<1> right?
<1> then the applet will read that page when needd
<1> needed*
<3> hey.. i'm kind of new but i was wondering... how do i convert a .jad file to .jar?
<1> .jad?
<1> So
<1> How do I get my applet to read an XML?
Return to
