  We find and analyse solutions of Einstein's equations in arbitrary d
dimensions and in the presence of a scalar field with a Liouville potential
coupled to a Maxwell field. We consider spacetimes of cylindrical symmetry or
again subspaces of dimension d-2 with constant curvature and analyse in detail
the field equations and manifest their symmetries. The field equations of the
full system are shown to reduce to a single or couple of ODE's which can be
used to solve analytically or numerically the theory for the symmetry at hand.
Further solutions can also be generated by a solution generating technique akin
to the EM duality in the absence of a cosmological constant. We then find and
analyse explicit solutions including black holes and gravitating solitons for
the case of four dimensional relativity and the higher-dimensional oxydised
5-dimensional spacetime. The general solution is obtained for a certain
relation between couplings in the case of cylindrical symmetry.
