i want to get some data from the data base and view it in a jsp page.
for the moment am just creating a list in the action class to finish the view part am using the <s:iterator> to create the <td> of my table and here is what i am doing:
the CampaignData.jsp:

<form id="CampaignForm" action="campaignDataAction.action" method="post">
<table border="0">
<tr>
<th>NOM</th>
<th>ID</th>
<th>Treatment_Code</th>
<th>Date_Creation</th>
<th>Date_Prevue_Envoi</th>

<th>Date_Envoi</th>
<th>Historisation_Cible</th>
<th>Historisation_Temoin</th>
<th>canal</th>
<th>test</th>
<th>status</th>
</tr>
<s:iterator value="campaigns" status="campaign">
<tr>
<td><s:property value="nom" /></td>
<td><s:property value="id" /></td>
<td><s:property value="treatmentCode" /></td>
<td><s:property value="dateCreation" /></td>
<td><s:property value="datePrevueEnvoi" /></td>
<td><s:property value="dateGeneration" /></td>
<td><s:property value="dateEnvoi" /></td>
<td><s:property value="historisationCible" /></td>
<td><s:property value="historisationTemoin" /></td>
<td><s:property value="canal" /></td>
<td><s:property value="test" /></td>
<td><s:property value="status" /></td>
</tr>
</s:iterator>
</table>
</form>

the CamapaignDataAction.java:

package action;

import java.util.ArrayList;
import java.util.List;

import model.CampaignInfo;

import com.opensymphony.xwork2.ActionSupport;

public class CampaignDataAction
extends ActionSupport
{
/**
*
*/
private static final long serialVersionUID = 1L;

private CampaignInfo campaign;

private CampaignInfo campaign1;

private List<CampaignInfo> campaigns;

public String execute()
{
campaigns = new ArrayList<CampaignInfo>();
campaign = new CampaignInfo();
campaign.setCanal( "test" );
campaign.setDateCreation( "test" );
campaign.setDateEnvoi( "test" );
campaign.setDateGeneration( "test" );
campaign.setDatePrevueEnvoi( "test" );
campaign.setHistorisationCible( "test" );
campaign.setHistorisationTemoin( "test" );
campaign.setId( "test" );
campaign.setNom( "test" );
campaigns.add( campaign );
campaign1 = new CampaignInfo();
campaign1.setCanal( "test" );
campaign1.setDateCreation( "test" );
campaign1.setDateEnvoi( "test" );
campaign1.setDateGeneration( "test" );
campaign1.setDatePrevueEnvoi( "test" );
campaign1.setHistorisationCible( "test" );
campaign1.setHistorisationTemoin( "test" );
campaign1.setId( "test" );
campaign1.setNom( "test" );
campaigns.add( campaign1 );
return "success";

}

/**
* @return the campaign
*/
public CampaignInfo getCampaign()
{
return campaign;
}

/**
* @param campaign the campaign to set
*/
public void setCampaign( CampaignInfo campaign )
{
this.campaign = campaign;
}

/**
* @return the campaign1
*/
public CampaignInfo getCampaign1()
{
return campaign1;
}

/**
* @param campaign1 the campaign1 to set
*/
public void setCampaign1( CampaignInfo campaign1 )
{
this.campaign1 = campaign1;
}

/**
* @return the campaigns
*/
public List<CampaignInfo> getCampaigns()
{
return campaigns;
}

/**
* @param campaigns the campaigns to set
*/
public void setCampaigns( List<CampaignInfo> campaigns )
{
this.campaigns = campaigns;
}

}
