Layout layoutForPortletName = LayoutLocalServiceUtil.getLayout(plidSelected);

LayoutTypePortlet layoutTypePortletName = (LayoutTypePortlet)layoutForPortletName.getLayoutType();

LayoutTemplate layoutTemplate=layoutTypePortletName.getLayoutTemplate();

List columnCount = layoutTemplate.getColumns();

for(int i=0; i
String column = columnCount.get(i);
List portlets = layoutTypePortletName.getAllPortlets(column);

for(Portlet portlet : portlets){

PluginPackage pluginPackage = portlet.getPluginPackage();
PluginSetting pluginSetting = PluginSettingLocalServiceUtil.getPluginSetting(company.getCompanyId(), portlet.getPortletId(), Plugin.TYPE_PORTLET);

StringBuilder sb = new StringBuilder();

String displayName = portlet.getDisplayName();
String title = PortalUtil.getPortletTitle(portlet, application, locale);
