Ok so I'm making my own custom mod launcher based off of Spoutcraft-Launcher, however when I load the class files I get a huge error saying that Forge can't find a particular file.

 

Here is the error: http://pastebin.com/5qFumAB3

 

Here is my source code: https://github.com/thehutch/Science-Launcher/tree/master/Spoutcraft%20Launcher/src/main/java/org/spoutcraft/launcher

 

This error shows once Forge gets to the "Minecraft Validation" when that window pops up so I'm assuming forge is blocking it?

 

If there are any more details you need please let me know.

Don't use MinecraftApplet.

How am I meant to load the minecraft client then? I guess I could look at the Technic-Launcher code although it's a complete mess in my opinion

Minecraft.main works just fine.

I still seem to be getting this error ;( Any chance anyone could tell me where I should be looking for this error 

 

Also I've changed a lot of stuff from before so here is the error again and the code:

Any feedback is greatly appreciated 

Use Minecraft.main instead of MinecraftApplet

I'm assuming you're talking about this code here:

 

ClassLoader classLoader = new MinecraftClassLoader(urls, ClassLoader.getSystemClassLoader(), jarmods, files);
String nativesPath = new File(mcBinFolder, "natives").getAbsolutePath();
System.setProperty("org.lwjgl.librarypath", nativesPath);
System.setProperty("net.java.games.input.librarypath", nativesPath);

appletClass = classLoader.loadClass("net.minecraft.client.MinecraftApplet");
mcClass = classLoader.loadClass("net.minecraft.client.Minecraft");
mcField = appletClass.getDeclaredFields()[1];
return (Applet) appletClass.newInstance();

 

I'm changing this but obviously Minecraft.main isn't a class but a method...

 

Is there something else I'm meant to do?

Thats creating a new applet, and initalizing it using the init method.

Dont

Use Minecraft.main

Ok so I removed the init() from the Applet but now nothing is running except for a new window

 

Not to be rude, but saying Don't use MinecraftApplet, use Minecraft.main isn't exactly helpful, you've said it enough time, I just asking how and where do I put this code to get it working.  :P

Ok so I found this thread, but it doesn't say anything about how to fix, all I know is that for some reason FML is relaunching the Applet

Still not seeing whats so complicated, I've told you what you should do.

Go do it.
