When uploading mesh i noticed it was always free, first i thought it was comming from the Money Component

but Foto did a good job there as it triggered on mesh upload, so i investigated further, i wont go into to much detail here is the solution to get jOpenSimMoney to play nice with Mesh Uploads

in opensim.ini right below [Economy] add these datas:
MeshModelUploadCostFactor = 1.0
MeshModelUploadTextureCostFactor = 5.0
MeshModelMinCostFactor = 5.9
in my case this worked nicely a mesh with a landimpact of 38 will cost 59 Of my currency to upload, these values are floats, experiment with them as you see fit
