java.lang.ClassNotFoundException. File config issues!

[LaertesSon]

I am making a mod where I have multiple items with textures. I am using the

 

public void registerIcons(IconRegister iconRegiste

 

method. I am having issues putting my mod onto a Minecraft client but it works perfectly in Eclipse. Does anyone know the method where you put the images directly into the Eclipse package instead of into the MCP folders?

 

EDIT:

I have isolated the problem with my mod and textures are not the issue, I believe it is the location of the class files. My mod works 100 percent perfectly in Eclipse but when ported to a minecraft client it does not work at all. I have it set up like so:

 

ROOT OF ZIP

<.class files here>

<mods>

      <resources>

              <textures>

                    <items>

                        <.pngs here>

 

 

All my mod does is add some items to the game to use currency. I think I have the .zip's configuration wrong because it doesn't seem to be finding any of the class files wherever it's choosing to look, which obviously is not where I have chosen to put my class files. Here is the full error report if it helps:

Your structure must look like this:

<zip root>

      |- net

            |- thelors

                  |- creditmod

                        |- <class files>

      |- mods

            |- MYMODNAME

                  |- textures

                        |- items

                              |- <png files>

 

The folder structure for one class file must match it's packet definition, meaning if you have the packet set to "mypacket.subpacket.mod", the folder structure must be "/mypacket/subpacket/mod/classfile.class"

 

If you don't override the registerIcons method in your items and instead use the unlocalized name for texture specifying, you have to prepend MYMODNAME: (with the colon) to your unlocalized name, MYMODNAME is a custom mod name (in both, the unloc-name and the folder name). Here's an example:

"ClaySoldiers:horseDoll"
