Now i changed my code like this

Action

public String InserQuestionCategory(){ AdminQuestionCommon QstManageObject= new AdminQuestionCommon(); //insertion QstManageObject.InsertQuestionCategory(qstCategory); //filling QstManageObject.fillqstCategoryList(qstCategoryList); //making the property nullfor category qstCategory=""; return "success"; }


Struts.xml

<action name="InserQuestion" class="bean.CreateQuestionCategory" method="InserQuestionCategory"> <result name="success">/blgCreateQuestionCategory.jsp</result> <result name="error">/errorPage.jsp</result> <result name="input">/blgAskQust.jsp</result> </action>

Now the text box get cleared and my on refresh its agin getting submitted



JSP

<s:form >
<s:textfield name="qstCategory" label="Enter Question Category"/>
<s:submit action="InserQuestion"/>
</s:form>

<DIV style="border:1px solid white; float:left;">

<s:iterator status="stat" id="qstCategoryList" value="qstCategoryList"> <s:if test="%{(#stat.index%2)==0}"> </s:if> <s:else> </s:else> </s:iterator>

<s:property value="value"/>

<s:property value="value"/>

</DIV>

waiting for a solution

Wht i want to do is..
I had page which displays list of category. and i have a text box and a submit button to insert new category
i have an insert method inside my action class through wich i am insring the new entry. so on the submit button click i am calling that method. But i am filling the list that need to be show in the page is in exec method. So when i am calling the insert method and dircting to the same page it wont lits those which i inserted

Action to the page through with i am Listing data [blgCreateQuestionCategory page is used]
The same page also have an input box to enter the value and a submit button

<action name="ListQuestionCategory" class="bean.CreateQuestionCategory" > <result name="success">/blgCreateQuestionCategory.jsp</result> <result name="error">/errorPage.jsp</result> <result name="input">/blgAskQust.jsp</result> </action>

Action to insert the value. after inserting i am rediectint to the same action that also redirect to same page
then i am refreshing the page the "InserQuestion" is happening aging

<action name="InserQuestion" class="bean.CreateQuestionCategory" method="InserQuestionCategory"> <result name="success" type="chain">ListQuestionCategory</result> <result name="error">/errorPage.jsp</result> <result name="input">/blgAskQust.jsp</result> </action>

Hi all,
I am facing a problem of resubmition in struts. I had filled a page and submitted it. its is gone to my db and agin redirected to the same page . All data that i previously entered is filled in those fields. and if i am ginve refresh by right clicking the broswer the last trasaction agin happening and the page get submitted. HOw can i resolve this page

I had listed the part of struts.xml file using which i am executing the giveAnswer method in my action class.

<action name="giveAnswer" class="bean.GetAnswerConversations" method="giveAnswer">


I got the setter and getter method in the Action class GetAnswerConversations. But when i am accessing the value i am getting null . Why it happends

i got it . But i dont know wether it is the actual way to do it...


bean class


ArrayList blgQuestionList; public void setBlgQuestionList(ArrayList blgQuestionList){ this.blgQuestionList=blgQuestionList; } public ArrayList getBlgQuestionList(){ return this.blgQuestionList; }


fillQuestionList class used to fill the ArrayList



public class fillQuestionList { Statement stmt=null; ResultSet rsltSet=null; PreparedStatement pst=null; public void fillCategory(ArrayList qstCategory){ System.out.println("insied fillCategory [2]"); commonConnection conObj= new commonConnection(); Connection con=conObj.getConnection(); try{ stmt = con.createStatement(); rsltSet = stmt.executeQuery("select qstId,usrID,qstDesc,qstDate,qstCategory,qstStatus from blgQuestions"); while(rsltSet.next()){ qstCategory.add(new blgQuestions((String)rsltSet.getString("qstId"),(String)rsltSet.getString("usrID"),(String)rsltSet.getString("qstDesc"),(String)rsltSet.getString("qstDate"),(String)rsltSet.getString("qstCategory"),(String)rsltSet.getString("qstStatus"))); } }catch(Exception ex){ if (con != null){ System.err.print("Transaction is being fillCategory"); System.err.println("rolled back"); System.err.println(ex.getMessage()); } } } }


Plain Objec(Pojo) class


String qstId; String usrID; String qstDesc; String qstDate; String qstCategory; String qstStatus; public blgQuestions(String qstId,String usrID,String qstDesc,String qstDate,String qstCategory,String qstStatus){ this.qstId=qstId; this.usrID=usrID; this.qstDesc=qstDesc; this.qstCategory=qstCategory; this.qstStatus=qstStatus; } public String getQstId() { return qstId; } public String getUsrID() { return usrID; } public String getQstDesc() { return qstDesc; } public String getQstDate() { return qstDate; } public String getQstCategory() { return qstCategory; } public String getQstStatus() { return qstStatus; } public void setQstId(String qstId) { this.qstId=qstId; } public void setUsrID(String usrID) { this.usrID=usrID; } public void getQstDesc(String qstDesc) { this.qstDesc=qstDesc; } public void setQstDate(String qstDate) { this.qstDate=qstDate; } public void setQstCategory(String qstCategory) { this.qstCategory=qstCategory; } public void setQstStatus(String qstStatus) { this.qstStatus=qstStatus; } }

JSP Code


<table border="1" id="country" > <tr> <td>Question</td> </tr> <s:iterator id="blgQuestionList" value="blgQuestionList"> <tr> <td><s:property value="qstDesc"/></td> </tr> </s:iterator> </table>


It is using an object for each row. Wether it will create problem with garbage collection which in terms reduse the speed of my application .

Dear all,


i am fasing a proble with session . I am not able to get the session in the action class can anybody help me.I am giving the code that i used to put a hash table to session


HttpSession session; HttpServletRequest request; ActionContext ctx ; public String loginCheck(String UserName,String Password) { ctx = ActionContext.getContext(); request = (HttpServletRequest)ctx.get(ServletActionContext.HTTP_REQUEST); session = request.getSession(); Hashtable userDet=new Hashtable ----------------------- ---------------------- session.putValue("usrDet",userDet);


The same session i am tring to access inside another action but i faile . i got it as null. the code i am displayin bellwo

ActionContext context = ActionContext.getContext (); HttpServletRequest request = (HttpServletRequest) context.get(ServletActionContext.HTTP_REQUEST); HttpSession session = request.getSession (true); System.out.println("INSED INSERTQUESTION******************"); Hashtable userDet=(Hashtable)session.getAttribute("usrDet"); System.out.println("INSED "+(String)userDet.get("usrId"));

Thaks a lot . That worked fine.

But i still have some doubt in that concept. When we create a object. The values are assigned to the appropriate variables. when i am creating other with other the list hold object of diffrent values in each position. So why we need to use the bean property getter and settter since it will also do the same one.

I am using a class now with two field key and value


package bean; public class AnsCategory{ String key; String value; AnsCategory(String key,String value){ this.key=key; this.value=value; } }


i filled to to list

List qstCategory


qstCategory = new ArrayList();
qstCategory.add(new AnsCategory("A","AAA"));
qstCategory.add(new AnsCategory("B","BBB"));
qstCategory.add(new AnsCategory("C","CCC"));

getter and setter method


public List getQstCategory(){
return qstCategory;
}



and for <s:select

list="qstCategory" listKey="#qstCategory['key']"


I am not getting the proer value filled in the drop down
public void setQstCategory(List qstCategory){
this.qstCategory=qstCategory;
}




>

So if i created a class

Sucategory{
String id
String value
}

and i add object of the same to the list

and if i give like="list" listKey="id listValie="value" wether it will work

expecting replay
can i fill a <s:select using hashtable>

Dear all,
First i am thanking you all who helped me to solve the problme.

Now i need to fill a select combo <s:select with key and value attribute. I am able to fill it with only values but no key. How can i set key value for each option content in ><s:select>

<s:select label="Select Category" name="qstCategory" list="qstCategory" headerKey="1" headerValue="-- Please Select --" />

This is my select combo and i am listing the method that i used to fill the combo

private List day;
List qstCategory;
List qstCategoryKey;
String usrQst;


public String execute()throws Exception{ qstCategory = new ArrayList(); qstCategory.add("Sunday"); qstCategory.add("Monday"); qstCategory.add("Tuesday"); qstCategory.add("Wednesday"); qstCategory.add("Thursday"); qstCategory.add("Friday"); qstCategory.add("Saturday"); qstCategoryKey=new ArrayList(); qstCategoryKey.add("Sun"); qstCategoryKey.add("Mon"); qstCategoryKey.add("Tue"); qstCategoryKey.add("Wed"); qstCategoryKey.add("Thu"); qstCategoryKey.add("Fri"); qstCategoryKey.add("Sat"); return SUCCESS; } public List getQstCategory(){ return qstCategory; } public void setQstCategory(List qstCategory){ this.qstCategory=qstCategory; }
