I need to download some pdf files that are outside of my application, they are in the folder c: \ tmp \
How could you make use of primefaces to make these files available for download?
I thought about saving in folder C: \ jboss-as-7.1.1.Final \ standalone \ deployments \ app.war \ WEB-INF
but every time I deploy this file is deleted
Try this:
Declare an attribute of type DefaultStreamedContent in your bean:
Example:
private DefaultStreamedContent download;
Get the Get and sets:
public DefaultStreamedContent getDownload() {
return download;
}
public void setDownload(DefaultStreamedContent download) {
this.download = download;
}
Next:
//Método que faz o download do anexo
public void prepDownload() throws Exception {
File file = new File("c:/tmp/arquivo.pdf");
InputStream input = new FileInputStream(file);
ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
setDownload(new DefaultStreamedContent(input, externalContext.getMimeType(file.getName()), file.getName()));
}
Then on your button;
<p:commandButton icon="ui-icon-arrowthickstop-1-s"
title="Download Anexo"
actionListener="#{bean.prepDownload()}"
ajax="false">
<p:fileDownload value="#{bean.download}" />
</p:commandButton>
