Database connection in EJB

Question

Hi,
I am using a method for validating Userid and Password in a Session Bean. I could deploy and run it without any errors but the return value is null. The same bean If I am using with <JSP:usebean> tag the return value is correct. That means the database connection is OK. I am giving the code below.
public String validate(String UId,String PWd)throws RemoteException {
try{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
conn = DriverManager.getConnection("jdbc:oracle:oci8:scott/tiger@Everest");
st = conn.createStatement();
String str = "select * from T_CRM_WRK_LCTN where LOGINID='"+UId+"'";
ResultSet rs = st.executeQuery(str);
while(rs.next()){
login = (String) rs.getString("LOGINID");
if(login.equals(UId)){
pass = (String) rs.getString("PASSWORD");
break;
if( (UId.equals(login)) && (PWd.equals(pass)))
flg="Y";
else
flg="N";
st.close();
conn.close();
}catch(Exception e){}
return flg;
Can anyone help me what is the problem. Thanks in advance.

Hi,
Extension to the above problem, the problem is with the Connection. It is not able to establish the connection. Can anyone advise me about the possible reasons.
