Pessoal, estou tentando fazer o download pelo fileDownload do primefaces e ta dando erro:
Consegui fazer o upload(ele cria uma pasta com um nome e coloca os arquviso dentro dela).
Vou colocar os codigos do download aqui

public StreamedContent getFile() throws FileNotFoundException {  
	      
	        FileInputStream stream = new FileInputStream("C:\\arquivos_tecnico_sig\\");
	        file = new DefaultStreamedContent(stream, "C:\\arquivos_tecnico_sig\\",getDocumentoTecnico().getNome()); 
	        return file;  
	  }

<p:column width="4%">
				<p:commandButton value="Download" ajax="false">
						<p:fileDownload value="#{documentoTecnicoBean.file}"/>
						<f:setPropertyActionListener target="#{tecnicoSessaoBean.nomeDocumento}" value="#{documentoTecnico.nome}"/>
				</p:commandButton>
			</p:column>

erro:

AVISO: /pages/restrito_tecnico/lista_documento.xhtml @70,61 value="#{documentoTecnicoBean.file}": Error reading ‘file’ on type tecnico.web.DocumentoTecnicoBean

Fiz uma modificacao no metodo do Bean. ficou assim

public StreamedContent getFile() throws FileNotFoundException {  
	      
		  
		  	String caminho="C:\\arquivos_tecnico_sig\\"+getDocumentoTecnico().getNome()+"\\";
		  	String arquivo=""+getDocumentoTecnico().getNome()+"";
		  	
	        FileInputStream stream = new FileInputStream(caminho);
	        file = new DefaultStreamedContent(stream, caminho, arquivo);
	        return file;  
	  }

o erro mudou também!
