Your not going to like what I say and there is no easy way of saying it, but as far as I am aware, Spain does not pay job seekers allowance.
Unlike the UK where you can claim unemployment benefits, Spain only pays out to those that have worked and payed into the Spanish system and then its calculated on how much you have payed in as to how much and how long you receive any kind of unemployment subsidy.
To be entitled to unemployment benefit in Spain, taken from another web site
Unemployed workers in Spain have the right to receive benefit if they have
contributed the social security over a minimum period of
360 days within the
last 6 years before they get unemployed.
The
amount that the unemployed shall receive will depend on the contributions they have made within the last
180 days. There exist a minimum and maximum amount of benefit they may receive.
You retain the right to unemployment benefits for a
maximum period of
2 years, provided that you have
worked during 6 years before becoming unemployed.
They must
register as unemployed with the Spanish Institute of Employment (INEM) and apply for their unemployment benefit within
15 days of becoming unemployed.
They must be
legally unemployed to receive the benefit, they have no right to this benefit when it had been their own decision to terminate their work contract and therefore become unemployed.
As a general rule,
employers or
self-employed persons are not entitled to unemployment benefit
. However, it is possible to do some spare time work and still get unemployment benefit.

What some people have been doing is living in Spain and signing on in the UK. A few years ago there was a UK benefits fraud hot line set up in Spain to try and cut down on the problem.
