Your puppy will likely grow out of it.

Some things you can do to help her:

Have people kneel down and let her go to them.
Don't allow people to lean over her.
Ask people to pet her under the chin or on the chest, not on top of the head or body.
Ask people not to make eye contact with her, and not to speak to her in a high pitched tone.

Ignore the actual urination, any attention you give it whatsoever, will be counterproductive.

May I ask what age and breed your puppy is?
