totcols = i;
int j = 1;
ArrayList arr = new ArrayList();
ArrayList arrnm = new ArrayList();
while (results.next()) {
for (int k = 1; k <= i; k++) {
String s2 = resultsetmetadata.getColumnName(k);
int coltype = resultsetmetadata.getColumnType(k);
String s3 = null;
if(coltype == java.sql.Types.CLOB) {
Clob fileAsCLOB = null;
long length = 0;
fileAsCLOB = results.getClob(resultsetmetadata.getColumnName(k));
if(fileAsCLOB != null) {
     length = fileAsCLOB.length();
     s3 = fileAsCLOB.getSubString(1, (int) length);
} else {
s3 = results.getString(resultsetmetadata.getColumnName(k));
if (!arrnm.contains(s2)) {
s2 = setString(s2);
arrnm.add(s2);
s3 = setString(s3);
arr.add(s3);
j++;
this.x= arrnm;
public ArrayList getxArrList() throws RemoteException {
try {
     return x;
--------------------------------------------------StlBean---------------------------------------------------
Problem is with getxArrList() ,We not getting the correct value of x when tested for 2 users.
