Dijkstra's algorithm to find all the shortest paths possible

I'm working on Dijkstra's algorithm, and I really need to find all the possible shortest paths, not just one. I'm using an adjacency matrix and I applied Dijkstra's algorithm, and I can find the shortest path. But I need to find all the paths with that minimum cost, I mean all the possible solutions, if they exist.

This is how my algorithm works, for a single solution:

public void dijkstra( int graph[][] )
{
    int d[] = new int[ graph.length ];
    int dC[] = new int[ graph.length ];
    int p[] = new int[ graph.length ];

    for( int i = 0; i < graph.length; i++ ){
        d[ i ] = 100; dC[ i ] = 100; p[ i ] = -1;
    }
    d[ 0 ] = 0; dC[ 0 ] = 0;

    int i = 0, min = 200, pos = 0; //You can change the min to 1000 to make it the largest number
    while( i < graph.length ){
        //extract minimum
        for( int j = 0; j < dC.length; j++ ){
            if( min > d[ j ] && dC[ j ] != -1 ){
                min = d[ j ]; pos = j;
            }
        }
        dC[ pos ] = -1;

        //relax
        for( int j = 0; j < graph.length; j++ ){
            if( d[ j ] > graph[ pos ][ j ] + d[ pos ] ){
                d[ j ] = graph[ pos ][ j ] + d[ pos ];
                p[ j ] = pos;
            }
        }
        i++; min = 200;
    }

    for( int j = 0; j < p.length; j++ ){
        System.out.print( p[ j ] + " " );
    }
    System.out.print( "\n" );
    for( int j = 0; j < d.length; j++ ){
        System.out.print( d[ j ] + " " );
    }
    System.out.print( "\n" );
}
