Java Help

LordUsagi · Aug 9, 2012

Howdy, as you can see by my post count I am fairly new here.

It has been about 2 years since I've done any kind of work with Java so I'm coming into this Pokemon development scene a bit sloppy and I'm noticing an error I get when I try to build a file.

Code:

package org.ini4j does not exist

Anyways, it's almost every single import erroring. Not sure what's up but any assistance would be helpful, and I am happy to share contact info if you'd like to speak more instantly

EDIT: Disregard this. I was using JCreator. But after following DefaulTs tutorial about using eclipse I managed to get it all working fine. Although I will pose another question.

When I use the default pokenet client, all kind of things go wrong. My pokemon dont show when I click on it, when I enter battles things bug out, movement is sloppy etc. The major bug being that, half the time it won't connect to my server. Says something about the account server.. But when I use Pokemoniums client all that seems fine and dandy. Nothing goes wrong, at all. Billposts have text, so does everything.

With pokemon not appearing the common result is not using jre6. i think. Jre7 causes this erro? or it's the other way around. Try both of them.
And try this lib folder: Download lib.rar @ UppIT
Just extract it and overwrite the current LIB folder.

Thanks for the quick response, unfortunately that did not fix it and seems to have caused more problems. Everytime I enter a battle now, I get a huge error log in the client. Not sure what's going on

I have used a fresh client with no modifications, as well as server. I disabled/enabled JRE 7. This error is new and makes no sense, when I had it atleast getting to the battle screen.

In the spoiler is all the errors I recieved.

Nothing new happened overnight with the computer, and it worked before I shut down and went to bed.

Edit: This happens when playing on other peoples servers, using their clients as well.

DeathLord17 · Aug 9, 2012

Whose source did you download?

LordUsagi · Aug 9, 2012

PokeNet, from the SVN. This bad boy https://github.com/StrickenFromHistory/PocketMonstersOnline

Then when I tried to play on Pokemonium (To troubleshoot if it was just my client or java as a whole) the same issue occurred, same errors. I'm currently using JRE 6 and JDK 6 if it's of any use.

DeathLord17 · Aug 9, 2012

Hmm, have you tried to do the disabling windows stuff? on the properties and compatibility menu?

LordUsagi · Aug 9, 2012

I'll give it a shot now BUT I would like to stress I was running it about 24 hours ago with no problems at all. (Except for the original one)

DeathLord17 · Aug 9, 2012

ok... i never had that happen to me (it just stop working) and neither has anyone that i know that has run the client.

LordUsagi · Aug 9, 2012

Haha, yeah

I didn't think it'd be a common issue. I'm going to completely uninstall JRE & JDK and reinstall them after a reboot. I'll let you know on my progress. Thankyou for the assistance by the way, you've been very friendly.

DeathLord17 · Aug 10, 2012

No problem. I've always been helpful to anyone who has asked for it.

LordUsagi · Aug 10, 2012

Aha! The complete uninstall and reboot fixed the issue with crashing in battle atleast on DefaulTs server. If I use my own server it errors every time I enter battle.

Seems to be a nullpointer, same errors as earlier.

DeathLord17 · Aug 10, 2012

Does the error mention anything like lwgj?

If you looked at the log above you'd know that it doesn't.

Looking at the log if you dont know what NullPointerException is, it is:

Calling the instance method of a null object
Accessing or modifying the field of a null object
Taking the length of null as if it were an array
Accessing or modifying the slots of null as if it were an array
Throwing null as if it were a Throwable value

I don't have time to take a look at how or why youre getting NPE but I would recommend deleting and recloning the project and recompiling then use defaults client and modify the server ip and see if that works (providing default hasnt made any changes to his client that would break your server) then if that is fine, recompile the client yourself and try that

Theres a amultitude of preasons why the null pointer happens, and i forgot he posted it his log.

Yes I know, I even put them in the post you quoted...

LordUsagi · Aug 12, 2012

Thanks for the assistance guys. I suppose I'll figure it out myself seeing as noone else has experienced it before.
