How to open pdf file in new window in JSF

<code>
<h:commandLink styleClass=”link-stock”
ajax=”false” immediate=”false” target=”_blank” >
<h:outputText value=”#{msg[‘pds.godownwisestock’]}” />

<p:fileDownload  contentDisposition=”inline” value=”#{applicationBean.downloadStockAsPDF}” />
</h:commandLink></code>

JSF Send asynchronous request using ajax

1) Create hidden ajax buttons and set “async=true” for those buttons to call parallel.
ex:

<p:commandButton id="districtUpdateCommodity" value="Test" immediate="true" async="true"
											actionListener="#{dashBoardBean.updateDistrictLevelDashboardCommodityDashBoardDto}"
											update="myPanel" style="display:none" />
<p:commandButton id="districtUpdateSales" value="Test" immediate="true" async="true"
											actionListener="#{dashBoardBean.updateDistrictLevelDashboardCommodityDashBoardDto}"
											update="myPanel" style="display:none" />

2) This buttons won’t call directly. We need to call by jquery on load method.

document.getElementById('form:reportQueryForm:districtUpdateSales').click(); document.getElementById('form:reportQueryForm:districtUpdateCommodity').click();

extCon.invalidateSession();
try {
FacesContext.getCurrentInstance().getExternalContext().redirect("session-timeout.xhtml?faces-redirect=true");
} catch (IOException e) {
// TODO Auto-generated catch block
