The crisis in Berlin in 1948-49 was due to Communist expansion in Europe. Germany was occupied by the 4 Powers (England, France, America, & Russia) as was the CITY of Berlin. It was at this time that Russia was consolidating its power throughout Eastern Europe starting with Poland and Czechoslovakia, Hungary Romania etc. Since Russia already controlled the eastern portion of Germany(East Germany) and Berlin was located in the middle of their territory, the Russians felt the Western powers,with a little pressure, would cede Berlin over to them since the West was demobilized and under prepared for another war. But when the Western powers , specifically the US & UK, didn't back down and threatened to nuke Russia instead, the Russians blockaded the city under the guise of "doing maintenance on the roads and rails". (Remember, the Russians didn't have the bomb yet). This blockade cut off all food, medical supples, gasoline and coal. Berlin, still in chaos from the war, was devastated and the citizen of the city were threatened with extinction. Because the military was allowed access through narrow air corridors, they came up with the idea to save the city via the now famous "Berlin Airlift".

Your question is vague, so the only crisis dealing with Berlin that I can think of would be the Berlin airlift. If this is the case JFK was not in office in 1949. He wasn't elected president until 1960. If you mean the Cuban crisis that is a different story.
Berlin Wall.
The Berlin Crisis of 1958 developed as a result of tensions between the Soviet Union and the Western powers over the status of West Berlin. The Soviet Union demanded that the Western powers withdraw their troops from West Berlin and threatened to hand over control of access points to East Germany. This led to increased military buildup and heightened fears of a potential conflict between the two sides. Ultimately, negotiations and diplomatic efforts helped defuse the crisis.
