Having an error trying to run GUI

@NerijusD Hi!

after ant dist run
cd build/distr and
java -cp "libs/*:libs/slik2d/*" fw.gui.MainSwingForm
for run gui form

This did not fix the problem, running java -cp "libs/*:libs/slik2d/*" fw.gui.MainSwingForm I getting Error: Could not find or load main class fw.gui.MainSwingForm

1、coyp l2walk.jar to l2walk\build\distr
2、change StartServer.bat edit：l2walker.jar fw.gui.MainSwingForm

[NerijusD]

@fmpoffice I did try your suggestion, but it didn't work or simply I didn't do it correctly.

StartServer.bat on line 7, contains:
java -server -Xms32m -Xmx64m -cp libs/*;libs/slik2d/*; fw.gui.MainAppForm
I did try replacing this line with:
java -server -Xms32m -Xmx64m -jar l2walker.jar fw.gui.MainSwingForm however still gave an error of Error: Could not find or load main class fw.gui.MainAppForm

Then I tried also:
java -server -Xms32m -Xmx64m -cp libs/*;libs/slik2d/*; fw.gui.MainAppForm -jar l2walker.jar fw.gui.MainSwingForm still have error:
Error: Could not find or load main class fw.gui.MainAppForm

What else is not right? Could it be my installation of Java?

[xMlex]

See https://github.com/xMlex/l2walker/blob/master/data/config/StartServer.bat#L7
Updated command to run in commit aca4330

And see README.md - section Build & run: https://github.com/xMlex/l2walker#build--run

[gigstox]

I have a similar problem, is there a solution?

[melg8]

@NerijusD, @gigstox, @xMlex it took only 4 years, i think i figured this one out

Issue was that in build.xml file its written as:

l2walker/build.xml

Line 92 in aca4330

<attribute name="Main-Class" value="fw.gui.MainAppForm" />

As you can see - MainAppForm.

But actually in files it is MainSwingForm

l2walker/java/fw/gui/MainSwingForm.java

Line 20 in aca4330

public class MainSwingForm extends Frame {

And for running it i used this bat file:

"C:\Program Files\Java\jre1.8.0_431\bin\java.exe" -jar l2walker.jar -cp "libs/*:libs/slik2d/*" fw.gui.MainSwingForm
pause

So you should have in build.xml MainSwingForm instead of MainAppForm, then it starts up, although i now get this error message:

15:44:46.956  Console configured.

I've revisited my bat file, this is version that works correctly:

"C:\Program Files\Java\jre1.8.0_431\bin\java.exe" -cp "build/distr/libs/*;build/distr/libs/slik2d/*;build/l2walker.jar" fw.gui.MainSwingForm
pause

My second problem was that using -cp and -jar commands at same time prevent -cp from running at all according to this answer

So when using only -cp command instead we achieve load of both l2walker part and lwjgl into program.
So now it starts bot properly:

So for anyone interested, full list of actions to do, for this program to run is:

To run bot

1. download source code
2. change MainAppForm -> MainSwingForm in this line:
   

   l2walker/build.xml

   Line 92 in aca4330

   <attribute name="Main-Class" value="fw.gui.MainAppForm" />

3. create run.bat in root of source code folder containing:

"C:\Program Files\Java\jre1.8.0_431\bin\java.exe" -cp "build/distr/libs/*;build/distr/libs/slik2d/*;build/l2walker.jar" fw.gui.MainSwingForm
pause

Keep in mind that your path of java might be different, so you will need to check where your jre (java runtime environment) is installed on your pc and change this part "C:\Program Files\Java\jre1.8.0_431\bin\java.exe" accordingly.
You can try shorter version:

java.exe -cp "build/distr/libs/*;build/distr/libs/slik2d/*;build/l2walker.jar" fw.gui.MainSwingForm
pause

4. run ant in root of source directory
5. run run.bat in root of source code directory

All of this were tested on windows 10. For linux should be similar with maybe usage of java instead of java.exe naming.
