出了个问题，找不出原因~找人帮看下~谢谢~

Question

我开发的是一个论坛系统~在回复模块上出现了点问题~数据提交不到数据库上，数据库上的信息也显示不到页面上。我的后台代码如下：
public ActionForward openShow(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response){ 
HttpSession session=request.getSession();
session.setAttribute("mainPage","/pages/show/bbs/openRootShow.jsp");String bbsId=request.getParameter("bbsId");
if(bbsId==null||bbsId.equals(""))
bbsId=(String)session.getAttribute("bbsId");
else
session.setAttribute("bbsId",bbsId);String sql="";
Object[] params={bbsId};
OpDB myOp=new OpDB();sql="select * from tb_bbs where bbs_id=?";
BbsForm bbsRootSingle=myOp.OpBbsSingleShow(sql, params);
session.setAttribute("bbsRootSingle",bbsRootSingle);String asker=bbsRootSingle.getBbsSender();
sql="select * from tb_user where user_name=?";
params[0]=asker;
UserForm askUser=myOp.OpUserSingleShow(sql, params);
session.setAttribute("askUser",askUser); int perR=6;
String currentP=request.getParameter("showpage");
if(currentP==null||currentP.equals(""))
currentP=(String)session.getAttribute("currentPopen");
else
session.setAttribute("currentPopen",currentP);
String gowhich="user/openShow.do?method=openShow"; myOp.setMark(true); myOp.setPageInfo(perR, currentP, gowhich); 
sql="select * from tb_bbsAnswer where bbsAnswer_rootID=? order by bbsAnswer_sendTime";
params[0]=bbsId;
List answerbbslist=myOp.OpBbsAnswerListShow(sql, params);
CreatePage page=myOp.getPage();session.setAttribute("answerbbslist",answerbbslist); 
session.setAttribute("page",page);sql="select * from tb_user where user_name=?";
Map answerMap=new HashMap();
for(int i=0;i<answerbbslist.size();i++){ 
String answerer=((BbsAnswerForm)answerbbslist.get(i)).getBbsAnswerSender();
if(!answerMap.containsKey(answerer)){
params[0]=answerer;
UserForm answerUser=myOp.OpUserSingleShow(sql, params);
answerMap.put(answerer,answerUser); 
}
}
session.setAttribute("answerMap",answerMap);return mapping.findForward("success");
}
public ActionForward answerBbs(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response){
HttpSession session=request.getSession(); 
BbsAnswerForm bbsAnswerForm=(BbsAnswerForm)form;String rootId=(String)session.getAttribute("bbsId"); 
String bbsTitle=Change.HTMLChange(bbsAnswerForm.getBbsAnswerTitle());
String bbsContent=Change.HTMLChange(bbsAnswerForm.getBbsAnswerContent());
String bbsSender=((UserForm)session.getAttribute("logoner")).getUserName();
String bbsSendTime=Change.dateTimeChange(new Date());
String bbsFace=bbsAnswerForm.getBbsFace(); String sql="insert into tb_bbsAnswer(bbsAnswer_rootID,bbsAnswer_title,bbsAnswer_content,bbsAnswer_sender,bbsAnswer_sendTime,bbsAnswer_face)values(?,?,?,?,?,?)";
Object[] params=new Object[6];params[0]=rootId;
params[1]=bbsTitle;
params[2]=bbsContent;
params[3]=bbsSender;
params[4]=bbsSendTime;
params[5]=bbsFace;ActionMessages messages=new ActionMessages();
String forwardPath="";OpDB myOp=new OpDB();
int i=myOp.OpUpdate(sql, params);
if(i<=0){
System.out.println("回复帖子失败！");
forwardPath="error";
messages.add("userOpR",new ActionMessage("luntan.bbs.answerR.E"));
}
else{
System.out.println("回复帖子成功！");
forwardPath="success";
messages.add("userOpR",new ActionMessage("luntan.bbs.answerR.S")); 
bbsAnswerForm.clear(); 
} 
saveErrors(request,messages);
return mapping.findForward(forwardPath);
}

</html>每次显示运行到了

select * from tb_user where user_name=?

后面就运行不下去了~
