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

@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?

See https://github.com/xMlex/l2walker/blob/master/data/config/StartServer.bat#L7 Updated command to run in commit https://github.com/xMlex/l2walker/commit/aca4330b9653a1488bcdebfa0a840a4c64f08b87

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

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: https://github.com/xMlex/l2walker/blob/aca4330b9653a1488bcdebfa0a840a4c64f08b87/build.xml#L92 As you can see - MainAppForm.

But actually in files it is MainSwingForm https://github.com/xMlex/l2walker/blob/aca4330b9653a1488bcdebfa0a840a4c64f08b87/java/fw/gui/MainSwingForm.java#L20

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:
