Thread: Eclipse when running the server/client

there are two issues at play here

firstly the issue you are having is called the classpath.

every java program has a main method and you have to tell java where that main method is

Code:

 java -cp bin server.Server

(not the real path just an example)

the above tells java to look for the class path in the bin folder and to search the package server for the class called Server which contains our main method

eclipse automates this process but you need to use the gui to tell it where the main method is still otherwise it's clueless.

your second issue is that rs is a multiplayer game played over a network, this is easier to manage using what's called a client-server model. every user has a client that interfaces with the server(s).

edit: with your edit my second point is not needed but I will keep it anyway.

Thanks for the reply.

I understood that the server.java was located in redone package. I changed the initiate.bat. However, like you have just mentioned, how do we "tell" eclipse where it is? I assumed that having the redone.server as the path would do that automatically.

here is the thing: eclipse does not know about the path in the .bat file.

.bat is windows specific extension

eclipse handles this separately, I haven't used it in a while but it should be in Run -> Run configurations, there should be an option to select the main class

I did this:

(not sure why image isnt showing but main class was changed to "redone.Server"

It now at least prints out in the terminal but there is a lot of errors like so:

Code:

item.cfg: file not found.
java.io.FileNotFoundException: .\data\cfg\prices.txt (The system cannot find the path specified)
	at java.io.FileInputStream.open0(Native Method)
	at java.io.FileInputStream.open(Unknown Source)
	at java.io.FileInputStream.<init>(Unknown Source)
	at java.util.Scanner.<init>(Unknown Source)
	at redone.world.ItemHandler.loadItemPrices(ItemHandler.java:339)
	at redone.world.ItemHandler.<init>(ItemHandler.java:36)
	at redone.Server.<clinit>(Server.java:63)
./Data/CFG/npc.cfg: file not found.
./Data/CFG/spawn-config.cfg: file not found.

Yes that is working now.

The server has tried to start but has not been able to locate the config files correctly.

First you need to see if the issue is that the path is incorrect, check if there is actually a data/cfg/prices.txt for example.

Note I'm not talking about the classpath here but the path to the configuration files.

Just a note folder names might be case sensitive so

Code:

 data/cfg

Code:

Data/CFG

Aren't always the same thing.

You're on Windows so it probably isn't an issue but something to keep in mind.

Thanks, the path is correct i.e. ./data/cfg/prices.txt so not sure why its not finding. prices.txt is there and is all lower case.

So this is for getting the server going. When i try to run other bat files. for example client folder that contains run.bat, it says

"The system cannot find the path specified.
Error: Could not find or load main class Main"

I tried configuring to Main, but that changes the server bat file too when i dont want to,

Does it find when running from the .bat ? Could be eclipse has not included the data folder in the project correctly.

nah.

So I have these folders:

2006redone Client:
compile.bat
run.bat

2006redone file_Server:
start.cmd

2006redone Server:
build.bat
initiate.bat

When i run initiate.bat the error is the same. SO i tried running build.bat and i get "Error: Unable to access jarfile libs/javac++.jar"

Editing the client run.bat will not change the server run.bat. The client classpath will be different though.
