L2J L2CraftManager compile error

[stalker989]

Hi, I know this is an age old question, but maybe you guys can help me out a bit. I am trying to install the L2CraftManager.java into my core server pack, but its giving me a compiling error:

F:\L2\EclipseWorkspace\L2jFrozenInterlude\trunk\gameserver\head-src\com\l2jfrozen\gameserver\model\actor\instance\L2CraftManagerInstance.java:335: error: cannot find symbol
    [javac]  					L2RecipeList _recipe = RecipeController.getInstance().getRecipeByItemId(_item.getItemId()); 
    [javac]  					                                                     ^
    [javac]   symbol:   method getRecipeByItemId(int)
    [javac]   location: class RecipeController

And I tried to fixed it, but I am not good at java, and don't know whats the issue.
