Upload com RichFaces

Bom dia a todos,

Preciso implementar upload com JSF e RichFaces,
Já procurei na internet por tutoriais, exemplos, mas nada deu certo até agora.

Eu tenho que escolher um arquivo e salvar em um diretório físico, mas não consigo de jeito nenhum.

se alguém puder me ajudar, segue o erro:

segue o código do bean:

public class UploadBean {

	public UploadBean() {
	}

	public void listener(UploadEvent event) throws Exception {
		UploadItem item = event.getUploadItem();
		OutputStream out = new FileOutputStream("C:/Upload/");
		try {
			out.write(item.getData());
			out.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}

a página jsf:

&lt;f:view&gt;
&lt;h:form&gt;
        &lt;h:panelGrid columns="2" columnClasses="top,top"&gt;
            &lt;rich:fileUpload fileUploadListener="#{fileUploadBean.listener}"
                maxFilesQuantity="1"
                id="upload"
                immediateUpload="true"
                acceptedTypes="pdf, doc" allowFlash="false" &gt; 
           
            &lt;/rich:fileUpload&gt;
             &lt;/h:panelGrid&gt;           
    &lt;/h:form&gt;
    &lt;/f:view&gt;

Obrigado :thumbup:

Eu consegui implementar a lógica para fazer upload em um diretório e não ficar só no temp

a lógica é a seguinte

public void listener(UploadEvent event) throws Exception {
		logger.info(&quot;iniciando upload&quot;);
		
		UploadItem upload = event.getUploadItem();
		if (upload.isTempFile()) {
			logger.info(&quot;Upload: &quot;+upload.isTempFile());
			String string[] = upload.getFileName().split(&quot;\\\\&quot;);
			arquivoUpload = new File(&quot;\\var\\transit\\cvload\\upload\\&quot; + string[string.length -1]);

			InputStream in = new FileInputStream(upload.getFile());
			OutputStream out = new FileOutputStream(arquivoUpload);
			byte[] buf = new byte[1024];
			int len;
			while ((len = in.read(buf)) &gt; 0) {
				out.write(buf, 0, len);
			}
			in.close();
			out.close();
     		logger.info(&quot;inserir anexo&quot;);
     		logger.info(&quot;FileVO: &quot;+ fileUploadVO);
     		logger.info(&quot;Arquivo Upload: &quot;+ arquivoUpload);
		} else {
			ByteArrayOutputStream b = new ByteArrayOutputStream();
			b.write(event.getUploadItem().getData());
		}
			logger.info(&quot;File: &quot;+ arquivoUpload.getPath());
	}

espero que ajude o pessoal que precisa
