java EJB

I have this code:

public ResultSet getAccounts() {

// Build the SQL query statement, embedding the AccountID variable
String strSQL = "SELECT AccountKey, AccountName, Balance from accounts " +
"WHERE UserKey = " + m_iUserID;

// Query the database
return dbMgr.executeQuery(strSQL);

If I want to pass the UserKey directly to the getAccounts method, how could I do so?
