You should iterate over List of Map instead of Map of List

Example :

@Getter
private List listOfMap = Lists.newArrayList();

public String execute() {

    while (resultset.next()) {
        final Map map = Maps.newHashMap();

        map.put("manufId", resultset.getString("manufacturer_id"));
        map.put("manufLogo", resultset.getString("SUPPLIER_LOGO_IMAGE"));
        map.put("manufName", resultset.getString("MANUFACTURER_NAME"));
        map.put("manufURL", resultset.getString("MANUFACTURER_URL"));

        listOfMap.add(map);
    }

    return SUCCESS;
}


  ${manufId}
  ${manufLogo}
  ${manufName}
  ${manufURL}

The listOfMap also can use as a dataSource for Struts2 JasperReports Plugin.
