在下 通过在EJB 的bean类(AccountEJB.java)中连接到(by type4)数据库, 读取记录and convert it to a VO object, then store the vo to a ArrayList( statement here),finally return the ArrayList.概要如下: .... ArrayList statement.add(vo);
if(statement.size() > 0){ return statement; }
throw new AccountException("Account not found.");
}catch(NamingException ex) { throw new EJBException(ex); }catch(SQLException ex) { throw new EJBException(ex); }finally {
try { if(iCtx != null) iCtx.close(); if(rs != null) rs.close(); if(stmt != null) stmt.close(); if(con != null) con.close(); //con.close()开始抛了一个异常,纳闷 }catch(Throwable th) { System.out.println("exception while closing coonection"); th.printStackTrace(); }
}
