Problem on running class file in ArborText Editor

Hi,

     Could any one please help why the below exception is coming when a menu is clicked in ArborText Editor.

          [A30135] Cannot load class CustomMenu because a dependent class was not found

CustomMenu is my custom class and it has some dependent jar files with folder contains some dependent class. I kept my CustomMenu.class and jar in the path \Arbortext Editor\custom\classes

          \Arbortext Editor\custom\classes\CustomMenu.class

          \Arbortext Editor\custom\classes\custom.jar

          \Arbortext Editor\custom\classes\org(this folder contains dependent class files for CustomMenu)

After applying this I started ArborText Editor and I clicked my Menu , I am getting ([A30135] Cannot load class CustomMenu because a dependent class was not found), error at the bottom of the Editor

Could any one please help on this

Thanks.

Prashant
