Does a spell stored in a weapon, using spell storing, keep the bonuses of the original caster

Question

So looking over this for 5th edition made me wonder if it is usually considered the same in 3.5 since it is not specified.

Spell Storing: A spell storing weapon allows a spellcaster to store a single targeted spell of up to 3rd level in the weapon. The weapon strikes a creature and the creature takes damage from it,the weapon can immediately cast the spell on that creature as a free action if the wielder desires. This special ability is an exception to the general rule that casting a spell from an item takes a least as long as casting that spell normally.... Once the spell has been cast from the weapon, a spellcaster can cast any other targeted spell of up to 3rd level into it. The weapon magically imparts to the wielder the name of the spell currently stored within it."(DMG,225)

So because of the last bit, is the wielder considered the caster for bonus purposes or is it the original caster? Is it considered the weapon? For example the damage added from a warmage's Int modifier from "warmage edge:... Whenever a warmage casts a spell that deals hit point damage, he adds his intelligence bonus (if any) to the amount of damage dealt...." (Miniatures Handbook, 15). Will the spell stored in the weapon retain the damage bonus?

"Spell storing: A spell storing weapon allows a spellcaster to store a single targeted spell of up to 3rd level in the weapon.(The weapon strikes a creature and the creature takes damage from it,the weapon can immediately cast the spell on that creature as a free action if the wielder desires.

The weapon casts the spell, not the wielder. Treat is as if the wielder was using UMD to activate a wand or scroll. I don't think the warmage's bonus would apply as he is not casting the spell, the weapon is (if a warmage were to make a scroll, the bonus would not carry through).

Answer 2

From Warmage Edge :

Scrolls scribed by a warmage do not gain any benefit from warmage edge. Scrolls activated by a warmage also gain no benefit from warmage edge. The same is true for most other magic items, such as wands and potions.

As Gaynorvader said,

The weapon casts the spell, not the wielder. Treat is as if the wielder was using UMD to activate a wand or scroll.

Therefore a spell cast by a warmage stored in a spell-storing weapon doesn't benefit from warmage edge.

In a more general way, when a wizard casts a spell from a scroll, he doesn't use his casting abilities (for determining variables based on caster level : duration, range, ... ; or his ability score for calculating DC). Likewise, a warmage can't add his warmage edge on a spell cast from a scroll.
