Not able to persist my arrayList in Struts2

[Shyam Sampath]

Hi,

I have recently started using Struts2. I have a jsp which iterates through an ArrayList of JavaBeans. And the jsp has some form fields for user input. The input data is stored in Arraylist as beans. As and when the user inputs data it ll displayed as rows one below the other. The problem I am facing is that I am not able to persist the arraylist, i.e. when the first data is entered it works fine. But when the second data is entered it replaces the first one instead of getting appended with it. I tried making the ArrayList hidden, but no luck. Could any one of you please help me with this issue?

I have attached the code for your reference.


This is my JSP

<table class="sortable" id="journalTable"; width="1050" align="center" 
					style="font-style: normal;font-family: sans-serif; font-size: smaller;" 
					cellpadding="5" border="2" bordercolor="#DCDCDC">
					<tr bgcolor="gray" style="font-style: normal;
					font-family: sans-serif; font-size: small;font-weight: bold;">
					<td onclick="javaScript: emptyArray();"> P&L Date</td>
					<td onclick="javaScript: emptyArray();"> Reversal Date</td>
					<td onclick="javaScript: emptyArray();"> Portfolio </td>
					<td onclick="javaScript: emptyArray();"> Org_FCC Id</td>
					<td onclick="javaScript: emptyArray();"> Trade Id(FCC_ID)</td>
					<td onclick="javaScript: emptyArray();"> Amount</td>
					<td onclick="javaScript: emptyArray();"> Currency</td>
					<td onclick="javaScript: emptyArray();"> Debit Account</td>
					<td onclick="javaScript: emptyArray();"> Credit Account</td>
					</tr>
					<s:iterator value="manualJournal" status="rowstatus">
					<s:if test="#rowstatus.odd == true">
					<tr bgcolor="LightSteelBlue">
					</s:if>
					<s:else>
					<tr bgcolor="white">
					</s:else>
					<td ><s:property value="PandL"/>
					</td>
					<td >
					<s:property value="reversalDate"/>
					</td>
					<td ><s:property value="selectedPortfolio"/>
					</td>
					<td ><s:property value="orgFCC"/>
					</td>
					<td ><s:property value="tradeId"/>
					</td>
					<td ><s:property value="amount"/>
					</td>
					<td ><s:property value="currency"/>
					</td>
					<td ><s:property value="debitAccount"/>
					</td>
					<td ><s:property value="creditAccount"/>
					</td>
					<td>
					<%-- <input type="checkbox" name = "removeRow" onclick="javaScript: manageArray(this.parentNode.parentNode.rowIndex,'<s:property value="id"/>' );"> --%>
					<input type="checkbox" name = "removeRow" onclick="javaScript: manageArray(<s:property value="id"/>,this.checked);">
					</td>
					</tr>
					</s:iterator>
					</table>

This is my action class

public String execute(){
		System.out.println("in Action++"+toPage);
		ManualJournalService mjService = new ManualJournalService();
		mjService.populateDropDown(journalTypeList, tradeRelated, portfolio, currency, accountList);
		ArrayList<ManualJournal> mjAdjustment = (ArrayList<ManualJournal>)getManualJournal();
		if(isCreateFlag()){
			ManualJournal mj = new ManualJournal();
			if(mjAdjustment!=null && mjAdjustment.size()!=0){
				mj.setId(1);
				for(int i=0;i<mjAdjustment.size();i++){
					System.out.println(mjAdjustment.get(i));
					//System.out.println("po----"+mj1.getSelectedPortfolio());
				}
				System.out.println(mjAdjustment.size());
				System.out.println("Here");
			}else{
				mj.setId(mjAdjustment.size()+1);
				System.out.println("Here1");
			}
			mj.setAmount(getAmount());
			mj.setJournalType(getJournalTypeName());
			mj.setTradeRelated(getIsTradeRelated());
			mj.setSelectedPortfolio(getPortfolioName());
			mj.setTradeId(getTradeId());
			mj.setPandL(getJournalTypeName());
			mj.setReversalDate(getJournalTypeName());
			mj.setDebitAccount(getDebitAccountName());
			mj.setCreditAccount(getCreditAccountName());
			mj.setComments(getComments());
			mj.setCurrency(getCurrencyName());
			System.out.println("Portfolio--"+ getPortfolioName());
			mjAdjustment.add(mj);
		}
		setManualJournal(mjAdjustment);
		setJournalTypeList(journalTypeList);
		setTradeRelated(tradeRelated);
		setPortfolio(portfolio);
		setCurrency(currency);
		setAccountList(accountList);
		int[] deletedRows = getDeleteRow();
		if(deletedRows !=null){
		System.out.println("length "+deletedRows.length);
		mjService.deleteRows(manualJournal, deletedRows);
		}
	/*	System.out.println("jou--"+getJournalTypeName());
		System.out.println("por--"+getPortfolioName());
		System.out.println("cur--"+getCurrencyName());
		System.out.println("tra--"+getIsTradeRelated());
		System.out.println("id--"+getTradeId());*/
		if(toPage!=null){
			return toPage;
		}else{
		return "success";
		}
	}

Thanks

You'll have to look into using indexed properties.
