Help. ! nullpointer fun

Question

I am reading stuff from a database [rms on a mobile fone]. i am having difficulty understanding why i am getting a null
pointer exception, having dynamically allocated the space necessary for storing the records in an array....
Later in another function, while attempting to copy a byteArray from RMS to the teamArray it gives nullptr exception.
Strangely if i just create a byteArray and put it in teamArray it is fine, [in the same for loop where space is allocated]
but in a different function [the one that reads in data] it bombs with nullPointer Exception...
public class RWstreams {
     private static RecordStore rs = null; // Record store
     static final String RECORD_STORE = "thers"; // Name of record store
public static byte[][][] byteArrays;
public static byte[][][] teamArray;
public static byte[][][] managerArray;
public static byte[][][] queueArray;
public static byte[] numplayersPerTeam;
private static long numbytes=0;
public RWstreams()
byteArrays = new byte[20][][]; //to store Player objects [ripped to byteArray]
teamArray = new byte[20][1][]; //to store Team objects [ripped to byteArray]
managerArray = new byte[20][1][];
numplayersPerTeam= new byte[20];
public static void InitRmsNoSave() {
     //pass in teams - each has 20 players
//Rip out each player array from team, [now represented as a byte array as has been persisted]
byte[] recData = new byte[ 200 ];
byte[] teamrecData = new byte[ 200 ];
byte[] managerrecData= new byte[200];
byte[] queuerecData = new byte[200];
// System.out.println("numteams:"+theTeams.length);
try{
rs.getRecord(1,numplayersPerTeam,0); //retrieve number of players per team...
for(int j=0; j<20;j++)
byteArrays[j]=new byte[numplayersPerTeam[j]][];
teamArray[j]=new byte[1][];
System.out.println("got value for team:"+j+" ->"+numplayersPerTeam[j]);
} catch( Exception e ) {
e.printStackTrace();
//Snippet from other function where copying to array is done:
          for(int teams=0; teams <20; teams++)//for every team
//retrieve no of players records to read into current team array
int thecounter=(int)numplayersPerTeam[teams];
for( int i = 1; i <= thecounter; i++ )
// Get data into the byte array
rs.getRecord( get, byteArrays[teams][i-1], 0 );<--------BOMBS here..:(
get++;
any help appreciated

Answer 1

ok sorry didnt read the bit about posting...
i pointed to the wrong piece of code incedentally. the line i said bombed is fine and works ok...
the bit that bombs is below....
  for( int i = 1; i <= thecounter; i++ )
                                 // Get data into the byte array
                                  //  System.out.println("length of array"+byteArrays[teams].length);
                                   rs.getRecord( get, byteArrays[teams][i-1], 0 );
                                   get++;
                                    System.out.println("team:"+teams+" Retrieved player:"+i);
                           rs.getRecord(get, teamArray[teams][0], 0);  <---- THIS IS THE BIT THAT BOMBS
                           get++;
                       any help appreciated
