In a form I have the field where I enter the name and create a folder with that name, in the second form a selectedOneMenu where lists the folders I created in the first form, now my problem is in the upload form because when I select a folder in selectedOneMenu and click to upload the file, it is not uploading, the variable where I store the folder name is getting null, down to my class who does these operations and the form if anyone can help I am grateful:
<div class="f2">
<label class="fname">
<h:form>
<center>
<label class="fname">
Criar Pasta de Upload: <h:inputText value="#{upload_file.pasta}"/>
<p:commandButton value="SALVAR" class="btnSalvar" action="#{upload_file.criarDiretorioMacro()}" onclick="#"/>
Selecionar Pasta Para Upload:
<h:selectOneMenu id="para" value="#{upload_file.destino}" style="width: 100px" >
<f:selectItem itemLabel="selecione" itemValue=""/>
<f:selectItems value="#{dir_controle.selectedDs()}" />
</h:selectOneMenu>
</label>
</center>
</h:form>
<h:form class="upload" >
<p:fileUpload fileUploadListener="#{upload_file.handleFileUpload}" mode="advanced" dragDropSupport="false"
multiple="true" update="messages" sizeLimit="100000" fileLimit="100" allowTypes="/(\.|\/#_)(gif|jpe?g|png|bat|rar)$/"
/>
<p:growl id="messages" showDetail="true" />
</h:form>
<br></br>
</label>
</div>
public class Fileuploadview {
private String arquivo;
private String pasta;
private String destino;
public String getArquivo() {return arquivo;}
public void setArquivo(String arquivo) {this.arquivo = arquivo;}
public String getPasta() {return pasta;}
public void setPasta(String pasta) {this.pasta = pasta;}
public String getDestino() {return destino;}
public void setDestino(String destino) {this.destino = destino;}
public void criarDiretorioMacro() throws SQLException {
DirControle dir = new DirControle();
String directory = dir.selectedDir_CB().toString().replace("[", "").replace("]", "");
try {
File diretorio = new File(directory+"//"+getPasta());
diretorio.mkdir();
} catch (Exception ex) {
}
}
public void handleFileUpload(FileUploadEvent event) throws SQLException {
DirControle dir = new DirControle();
String directory = dir.selectedDir_CB().toString().replace("[", "").replace("]", "");
try {
byte[] arquivo = event.getFile().getContents();
String caminho = directory +"\\"+getDestino()+ "\\" + event.getFile().getFileName();
try ( // esse trecho grava o arquivo no diretório
FileOutputStream fos = new FileOutputStream(caminho)) {
fos.write(arquivo);
FacesMessage message = new FacesMessage("Succesful", event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, message); // mensagem pra saber se ouve sucesso
}
} catch (Exception ex) {
ex.printStackTrace();
System.out.println(ex);
}
}
}
So since this line of mine displays a list the value of it should not go to the value of selectedOneMenu below? On another screen I perform this procedure and it works normally <h:selectOneMenu id="to" value="#{upload_file.target}" style="width: 100px" > <f:selectItem itemLabel="select" itemValue="""/> <f:selectItems value="#{dir_control.selectedDs()}" />
