<1> Juvenille: google does
<0> I tried it believe me
<0> but I have a hard time understanding the core of it
<2> Juvenille: every left branch is garranteed to only contain elements less than this one, every right one is garranteed to contain elements greater than
<2> if you also balance the tree to that the left and right branches contain the same number of element then the search is very efficient (it's a standard binary search)
<2> that's about it
<3> what's the website for AJAX?
<4> if you balance the tree then it would be an AVL Tree, if you want read about them
<5> javaq: ....
<5> javaq: there IS no web site for AJAX
<5> it's a technique, not a product
<0> Anyone familiar with insertion sort?
<2> goto the library, and look for Algorithm and data structure books
<4> exactly
<2> this is (after all) a java duiscussion chan
<0> well... i understand it
<2> try #cs
<0> I'm unsure about something about it
<2> and take your homework questions with you to the library
<0> this is not a homework questions
<2> lol
<0> it's a question about understanding insertion sort
<2> still the wrong place to ask
<0> something specific about it
<4> calchas do you know about multicasting?
<2> verty very little
<2> -t
<2> and it seems little about typing tonight
<4> :( i'm having a problem that i don't understand
<2> ask, in case I have an idea, but don't hold out too much hope
<4> i think the problem is with the multicasting ip address
<4> look, i'm learning sockets and i decided to create a small messenger application
<2> are you awar that many routers will not p*** multi-casts ?
<4> yes, i've read about it
<2> I think you know more than me, sorry
<4> :(
<4> my problem is that i have run my program in one of my college lab and it works fine, but when i run it somewhere else where there's no LAN it doesn't seem to receive any packets from the server
<2> no LAN ?
<2> what is the connection
<4> and my question was, is it necesary to be on a LAN so multicasting to work
<4> my program doesn't work when i run it on a pc that isn't on a LAN
<4> but works when runs on a pc on a LAN
<2> you need to be in a network where multicasts are allowed (p***ed but the routers etc)
<2> what is the connection
<4> i got dsl on my house, where it doesn't work
<2> I bet the isp doesn't p*** multi casts
<2> they don't travel far on the net, as they are a huge potential traffic load
<4> that's what i thought, but wanted to confirm
<4> but i'll keep digging on to multicast networking to see if i can figure out another way
<4> of broadcasting
<2> I can't confirm, but it's my first guess
<4> or multicasting
<4> ok calchas thanks
<2> np
<2> good luck
<2> if I even thought loud about multicasting at work, they'ed take my hardware away
<4> thanks because i'm gonna need it
<4> lol :P
<2> we've had plant shutdowns due to packet storms in the past
<4> wow
<2> and that cost lots of $
<4> lucky me that we have a private lab only for these kind of things, just to try out stuff and keep learning
<2> nod
<4> so when we be working on a real company know what we doing :P
<6> How can i find out number of threads running under tomcat
<6> Also memory used by java application running under tomcat
<2> I thought there was a method in Thread cl*** to get the threads in a JVM
<2> System or Runtime have methods to get free and used mem
<6> I am not worried about System stats .. that i can get from vmstat/iostat/top etc
<2> that's good, what's your point
<6> i want to get java application specific stats .. thsi application is running in tomcat
<6> java aplication ofcourse
<2> that's what I just gave you
<6> ok
<2> see those two cl***es it's in one of them
<6> thanks!
<2> np
<2> btw, it's nothing to do with Tomcat, it's about the jvm
<6> yeah ...
<6> and actually how about Tomcat itself
<6> any ideas ?
<2> tomacat is just some cl***es in that jvm
<6> :)
<6> yes
<2> tomcat hasn't resources other than those in the jvm wher it runs
<6> sure
<6> calchas: i was able to find jvm mem methods in Runtime cl*** .. i checked System and Thread cl*** and they dont seem to have a way to get # of threads and stuff
<1> makihoni: did you find the answer yet?

<7> hi there
<8> good morning
<9> hi
<10> 0_o
<11> Anyone here familiar with Jaas? I'm getting the feeling from this tut I'm reading that Jaas authorization is mostly used for file authorization stuff, and not for just managing a login and giving access do different pages?
<11> by "pages", I mean functions and cl***es in my gui that is JPanels and stuff
<12> bushwakko, never used it, but its a generic authentication mechanism not especially yied to file access :)
<11> ok
<12> yied/tied
<11> good
<11> got it working with a simple text file now, so it should be easily portable to a DB or an authorizationcl*** we make ourselves later
<11> the problem is figuring out how I'm supposed to use it
<11> why isn't char serializeable?
<12> char is not an object.
<13> hi all
<14> hi
<5> hi
<14> when is finally{} block called? in case any exception is raised or it will be called in any case?
<5> xpx: it will be called in any case
<15> xpx: try it and see? will give you a better understanding possibly, since written explanations have failed for you already. :)
<15> hi joe
<16> hi... i'm a litle lost, i want to create a database with SQuirreL. The db will be used by some java aplications. It seems to be that the only way to create the tables and all is bye sql commands at SQuirreL, but does another way exist? witch tutorial do you recommend me?
<15> iguana_il: ask the author/vendor
<16> Clackwell: do u say send a mail to the authors?
<15> iguana_il: squirrel is an sql client only, right? forget the vendor/author, read the db engine manual.
<14> it is not called when exception is not raised...as i observed
<5> iguana_il: SQL is good for creating tables
<15> and see which db maintenance clients are available for it.
<5> xpx: then your code is very strange indeed
<15> xpx: post test case.
<15> xpx: to pastebin.com or so
<5> because finally{} runs in every case that the VM doesn't exit, and most in which the VM does exit
<16> Clackwell, so i've to read an sql tutorial. But i've to migrate from an Access (micro****) db to SQuirreL, how do i import the data?
<5> iguana_il: use Access to do it
<5> sheesh, set up an ODBC source to the other DB type, and use SQL
<16> Clackwell, i was thinking about change some fields at the old db, so that's why i'm gonna create a new one
<15> iguana_il: you cannot migrate from ms access (spare us the name scrambling, this is not kindergarten) to squirrel sql.
<16> jottinger, i've to export from Access to a CSV file? something like thtat?
<5> no
<5> access can connect to non-access databases
<15> iguana_il: you cannot migrate from ms word to calc.exe either.
<5> any ODBC source can be used
<16> i'm really new in db stuff... do U recommend me to start reading a sql tutorial? odbc tutorial? SQuirreL tutorial? or what?
<5> I recommend you read an access tutorial
<15> iguana_il: try to understand that squirrel sql is not a database engine. ms access is a combination of a database engine plus an sql client plus some more.
<15> if you want a database engine, pick one.
<16> jottinger, my utopia is to run my future aplication in a linux server... but with the option of install it at a stand alone windows SO pc. Do U still recommend me to read the access tutorial?
<5> if you're using access to develop a DB and need to export data from it... yes
<16> Clackwell, i thought that wouldn't be so hard to create a db from SQuirreL, i don't want to use it as an engine
<5> iguana_il: SQL is easy
<15> iguana_il: if you want to use a database engine, pick one. which one did you pick?
<5> the DDL for a specific DB engine might have variations, but even there it's pretty easy to work out what you need
<16> jottinger, jdbc?
<5> iguana_il: what about it?
<16> jottinger, jdbc is the connection between my program and the engine... ok?, but i think that my server has installed the sql server or something like that... what's the istandard at fedora core 4
<16> ?
<5> iguana_il: sounds like you need to read a LOT of tutorials
<5> it's almost like you're playing buzzword bingo with no comprehension of any of your tools
<16> jottinger, i'm new in linux, db and with a minor experience in java
