How to upload files without turning it to temporary file? (NetBeans JSF Primefaces) - jsf

Good day to all!
I've been making a simple web Application using Netbeans, JSF and Primefaces that can upload .csv, .jpeg/.jpg and .pdf files. I made 2 folders which was stored in drive C: (uploaded folder and tmp folder).
I assigned the "uploaded" folder to where the uploaded files are stored and the "tmp" for the .tmp of the uploaded files. I've been through many question threads and video tutorial which I followed correctly.
I also downloaded the commons fileupload and commons io and added it to the library. It is working fine, it displays that it is uploading and even saw the .tmp file on the folder i assigned it to.
But I cannot see the uploaded files on my "uploaded" folder.
So, my question is,
How can I upload these files into my "uploaded" folder.
Here are my codes:

Thank you for your response and help. looking forward to it!

The main reason it's failing as at now is that you haven't bound the value attribute to your backing bean variable, so getFile() will always return null and upload will do nothing.
You're still probably not going to get any results because it appears that you're trying to combine two different modes of operation of the <p:fileUpload/> component.
Simple mode
You don't define a fileUploadListener
You define a value attribute on the component and bind to the UploadedFile type attribute in your backing bean (which you have)
Advanced mode
You don't define a value attribute
You define a fileUploadListener which is bound to a method in your backing bean (which you also have)

Simple Jetty/JSF file upload won't submit

I've already looked at this one and the related tickets to no avail.
I have, what looks like the, simplest example possible
<h:form enctype="multipart/form-data" prependId="false">
<h:outputText value="File: "></h:outputText>
<h:inputFile value="#{configUploadController.uploadedFile}" />
<h:commandButton value="Save" type="submit" action="#{configUploadController.uploadFile}" style="color: red;"></h:commandButton>
</h:form>
I put a breakpoint in my uploadFile method but it never gits hit. when I remove the enctype from the form it does try to submit but then I get the obvious error...
javax.servlet.ServletException: Content-Type != multipart/form-data
And just for completeness, I remove the <h:inputFile> and enctype and can see my breakpoint being hit. When I set enctype to text/plain it DOESNT hit the breakpoint. However, when I set enctype to gibberish it DOES hit the breakpoint :(
Am I missing a dependency or config somewhere?
And in case it matters, my web.xml...

Instead of working around with a servlet (as per other answer) the actual problem was Jetty needs the multipart config setting up per multipart request.
Simple way to do this would be to add a filter that adds it as necessary, eg.
public class LoginFilter implements Filter {
private static final String MULTIPART_FORM_DATA = "multipart/form-data";
private static final MultipartConfigElement MULTI_PART_CONFIG =
new MultipartConfigElement(System.getProperty("java.io.tmpdir"));
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain filterChain)
throws IOException, ServletException {
HttpServletRequest httpServletRequest = (HttpServletRequest) request;
HttpServletResponse httpServletResponse = (HttpServletResponse) response;
String contentType = request.getContentType();
if (contentType != null && contentType.startsWith(MULTIPART_FORM_DATA))
request.setAttribute(Request.__MULTIPART_CONFIG_ELEMENT, MULTI_PART_CONFIG);
filterChain.doFilter(request, response);
}
}

How to implement FileUpload in embedded Jetty?
So, I haven't spent the time to track down why but jetty doesn't appear to like multipart forms. I got round it by using a servlet. Solution looks like this...
I've gone with ajax approach and a HTML form so I can specify my action, that matches the servlets pattern...
<form action="upload/config" enctype="multipart/form-data" method="post">
<h:inputFile id="file" />
<br />
<h:commandButton type="submit" value="Upload">
<f:ajax execute="file" render="#all"/>
</h:commandButton>
</form>
And the servlet...
import java.io.InputStream;
import java.io.OutputStream;
import java.nio.file.Files;
import java.nio.file.Path;
import javax.servlet.MultipartConfigElement;
import javax.servlet.annotation.MultipartConfig;

#Override

try {
// This needed to get access to the parts
MultipartConfigElement multipartConfigElement = new MultipartConfigElement((String)null);
request.setAttribute(Request.__MULTIPART_CONFIG_ELEMENT, multipartConfigElement);
Part filePart = request.getPart("file");
try ( InputStream inputStream = filePart.getInputStream(); ) {
// Do what you want with your part
} catch (Exception e) {
resp.setStatus(500);
}

FacesConverter is null (JSF 2.3, CDI 2.0)

I tried to setup a FacesConverter to display some entity through my JSF page as referenced in JSF specification.
I'm running the following:
- Open Liberty 19.0.0.11 (tested on 19.0.0.6 as well, don't ask me why this version, I picked randomly another one)
- Java Open JDK 13
- JSF 2.3
- CDI 2.0
I've added to my project the following web.xml:

The following faces-config.xml:
<?xml version="1.0" encoding="UTF-8"?>
<faces-config

</faces-config>
The following beans.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"

bean-discovery-mode="all"
version="2.0">
</beans>
I do have an AppConfig class, annotated with #FacesConfig(Version.JSF_2_3). All fine so far.
I've simple TestConverter annotated as such:
#FacesConverter(value = "testConverter", managed = true)
When looking through the BeanManager, my TestConverter seems to be available as it appears in the list.
My test.xhtml file looks like this:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:ui="http://java.sun.com/jsf/facelets">
<h:outputText value="#{testBean.selectedEntity.id}">
</h:outputText>
<br/>
<h:outputText value="#{testBean.selectedEntity}" converter="testConverter">
</h:outputText>
</html>
And my backing bean:
package com.test.beans;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
import javax.annotation.PostConstruct;
import javax.enterprise.inject.Any;
import javax.enterprise.inject.spi.Bean;
import javax.enterprise.inject.spi.BeanManager;
import javax.enterprise.util.AnnotationLiteral;
import javax.faces.view.ViewScoped;
import javax.inject.Inject;
import javax.inject.Named;
import com.test.entities.MyEntity;
#Named("testBean")
#ViewScoped
public class TestBean implements Serializable {
private List<MyEntity> listEntities;
private MyEntity selectedEntity;
#Inject private BeanManager beanManager;
#PostConstruct
public void init() {
this.listEntities = new ArrayList<MyEntity>();
for(int i = 0; i < 5; i++) {
this.listEntities.add(new MyEntity(i, "test_"+i, i+"_test"));
}
this.selectedEntity = this.listEntities.get(0);
Set<Bean<?>> beans = beanManager.getBeans(Object.class,new AnnotationLiteral<Any>() {});
for (Bean<?> bean : beans) {
System.out.println("bean: "+bean.getBeanClass().getName());
}
}
public List<MyEntity> getListEntities() {
return listEntities;
}
public void setListEntities(List<MyEntity> listEntities) {
this.listEntities = listEntities;
}
public MyEntity getSelectedEntity() {
return selectedEntity;
}
public void setSelectedEntity(MyEntity selectedEntity) {
this.selectedEntity = selectedEntity;
}
}
Should be all good right ? Well, at least it worked with Apache TomEE 8.0.0 PluME. But here on Open Liberty, I'm getting:
SRVE0777E: Exception émise par la classe d'application 'javax.faces.webapp.FacesServlet.service:236'
javax.servlet.ServletException:
at javax.faces.webapp.FacesServlet.service(FacesServlet.java:236)

at [internal classes]
Caused by: java.lang.NullPointerException:
at org.apache.myfaces.cdi.converter.FacesConverterCDIWrapper.getAsString(FacesConverterCDIWrapper.java:62)
... 1 more
So, it looks like my bean is instantiated but is null... Features of Open Liberty are javaee8-0 (to be sure there wasn't anything missing). In the example above, if I'm removing the "managed = true" in my converter, it works. Some bug within CDI ?
I investigated the issue and I found that it's caused by beanManager.getBeans call. The bean is registered in the beanManger (as you demonstrated), but it's just not retrieved properly. Since the Converter uses generics, you need to search by type instead of class. I opened an issue in the MyFaces community and provided a patch! :)
https://issues.apache.org/jira/browse/MYFACES-4311
The fix will be included in MyFaces 2.3.7.
Thanks for spotting this one!

How to make p:fileUpload work?

So guys , I've decided to do a college's "homework" using JSF 2.2 and PrimeFaces 5.0 and theoretically I'm at the end , but I have great difficulty uploading files and , after trying by the whole day , I decided to post. The problem is that the file does not go where it should go, but the method is performed and shows no errors and exceptions.
page.xhtml
<p:fileUpload id="msg"
fileUploadListener="#{processoCtrl.handleFileUpload}"

<p:messages id="messages" showDetail="true" autoUpdate="true" closable="true"/>
ManagedBean
public void handleFileUpload(FileUploadEvent event) {
ExternalContext extContext = FacesContext.getCurrentInstance().getExternalContext();
// I already tryed //WEB-INF// , \\WEB-INF\\ e \WEB-INF\ (who knows...)
File result = new File(extContext.getRealPath("/WEB-INF/" + event.getFile().getFileName()));
System.out.println("/WEB-INF/" + event.getFile().getFileName());
try {
FileOutputStream fileOutputStream = new FileOutputStream(result);
byte[] buffer = new byte[6124];
int bulk;
InputStream inputStream = event.getFile().getInputstream();
while(true) {
bulk = inputStream.read(buffer);
if (bulk < 0) {
break;
}
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
}
fileOutputStream.close();
inputStream.close();
FacesMessage msg = new FacesMessage("File Description", "file name: " +
event.getFile().getFileName() + " file size: " +
event.getFile().getSize() / 1024 + "Kb content type: " +
event.getFile().getContentType() + "The file was uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
} catch (IOException e) {
e.printStackTrace();
FacesMessage error = new FacesMessage(FacesMessage.SEVERITY_ERROR, e.getMessage(), "erro.");
FacesContext.getCurrentInstance().addMessage(null, error);
}
}

Servlet filter which is mapped on /home is not invoked when I open /home.xhtml

I am new to Java Enterprise Edition. I started learning from some YouTube videos, and recently started reading http://docs.oracle.com/javaee/6/tutorial/doc/ I finished chapter 15.
I tried to make my own filter.
I didn't use Java Servlet class. Because I want to use JSF pages, and as far as I know it is only possible to use Managed Beans with JSF pages, Whereas Servlet classes work with JSP. It is OK.
As far as I know the usefulness of login filter:
https://stackoverflow.com/tags/servlet-filters/info
[...] This is particularly useful when you have multiple pages for which
you'd like to check the logged-in user. Instead of copypasting the
same logic over all pages, you can use a Filter to have it in a single
place.
It is useful (as I know) in the case when a user type the URL directly into the browser for a page which require logged in user, so the filter will redirect him to the login page or continue if he is logged in.
I searched for any simple example to learn from but didn't find. I will put my simple example:
I have two JSF pages
one is named home.xhtml (which require logged in user)
the other one is named login.xhtml (filter must redirect to it if non-logged users seek home)
login.xhtml:
<h:form>
<h:panelGrid columns="2">
<h:outputLabel value="name:"/> <h:inputText value="#{user.name}"/>
<h:outputLabel value="password:"/> <h:inputSecret value="#{user.password}"/>
</h:panelGrid>
<h:commandButton id="btn" value="login" action="#{user.login()}"/>
</h:form>
home.xhtml:
<h:body>
Hello #{user.name}. You are welcome
</h:body>
User:
#ManagedBean
#SessionScoped
public class User implements Serializable
{
String name;
String password;
Authentication authentication;
public User()
{
authentication = new Authentication();
}
//Getters and Setters for name and password.
public String login()
{
if (this.getName().equals("user") &&(this.getPassword().equals("1234")))
{
authentication.setLoggedIn(true);
FacesContext context = FacesContext.getCurrentInstance();
context.getExternalContext().getSessionMap().put("auth", authentication);
return "home";
}
else
{
authentication.setLoggedIn(false);
FacesContext context = FacesContext.getCurrentInstance();
context.getExternalContext().getSessionMap().put("auth", authentication);
return "login";
}
}
}
Authentication:
#ManagedBean
#SessionScoped
public class Authentication implements Serializable
{
private boolean authenticated;
public Authentication()
{
authenticated = false;
}
public boolean isLoggedIn()
{
return authenticated;
}
public void setLoggedIn(boolean authenticated)
{
this.authenticated = authenticated;
}
}
LoginFilter:
#WebFilter(value = "/home")
public class LoginFilter implements Filter
{
#Override
public void init(FilterConfig filterConfig) throws ServletException
{
//throw new UnsupportedOperationException("Not supported yet.");
}
#Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws ServletException, IOException
{
HttpServletRequest req = (HttpServletRequest) request;
Authentication auth = (Authentication) req.getSession().getAttribute("auth");
if (auth != null && auth.isLoggedIn())
{
System.out.println("Filter is working");
chain.doFilter(request, response);
} else
{
System.out.println("Filter is working");
HttpServletResponse res = (HttpServletResponse) response;
res.sendRedirect(req.getContextPath() + "/login.xhtml");
}
}
#Override
public void destroy()
{
//throw new UnsupportedOperationException("Not supported yet.");
}
}
faces-config:
<navigation-rule>
<from-view-id>/login.xhtml</from-view-id>
<navigation-case>
<from-outcome>home</from-outcome>

</navigation-case>
<navigation-case>
<from-outcome>login</from-outcome>
<to-view-id>/login.xhtml</to-view-id>
<redirect/>
</navigation-case>
</navigation-rule>
web.xml:
<context-param>
<param-name>javax.faces.PROJECT_STAGE</param-name>
<param-value>Development</param-value>
</context-param>
<servlet>
<servlet-name>Faces Servlet</servlet-name>

<session-timeout>
30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>faces/login.xhtml</welcome-file>
</welcome-file-list>
Now when I type the URL of home.xhtml page (after clearing history & cookies) into the browser it is assumed to redirect me to login page. But instead it goes to home with empty value for name:
Hello #{user.name}. You are welcome is rendered as Hello . You are welcome
Even System.out.println("Filter is working"); not print anything.
Are you sure the filter is called? If there is nothing printed to System.out I guess not. The problem might be the servlet mapping.
You specified this:
#WebFilter(value = "/home")
public class LoginFilter implements Filter {...}
I think this only matches the url /home. Try to use /* or /home* (which is very limiting, I would not recommend it) instead.
Another thing: If you get Hello #{user.name}. You are welcome as output, then the FacesServlet is probably not called. This might have two reasons:
You use the wrong mapping. Try to call the page with /faces/home.xhtml or /home.jsf instead. The url depends on the type of mapping you have in the web.xml.
The FacesServlet is not configured correctly/at all in the web.xml.

JSF Upload File Failing

I've done this part of the form
<td>
<h:form enctype="multipart/form-data">
<p:fileUpload fileUploadListener="#{uploadBean.handleFileUpload(event)}"
mode="advanced"
update="messages"
multiple="true"
sizeLimit="2000000"
allowTypes="/(\.|\/)(pdf|doc?x|xls?x)$/"/>
<p:growl id="messages" showDetail="true"/>
</h:form>
</td>
and this event handler in class:
public class UploadBean {
/** Creates a new instance of UploadBean */
public UploadBean() {
}
private static final int BUFFER_SIZE = 6124;
public void handleFileUpload(FileUploadEvent event) {
ExternalContext extContext = FacesContext.getCurrentInstance().
getExternalContext();
File result = new File(extContext.getRealPath
("//WEB-INF//upload") + "//" + event.getFile().getFileName());
try {
FileOutputStream fileOutputStream = new FileOutputStream(result);
byte[] buffer = new byte[BUFFER_SIZE];
int bulk;
InputStream inputStream = event.getFile().getInputstream();
while (true) {
bulk = inputStream.read(buffer);
if (bulk < 0) {
break;
}
fileOutputStream.write(buffer, 0, bulk);
fileOutputStream.flush();
}
fileOutputStream.close();
inputStream.close();
FacesMessage msg = new FacesMessage("Succesful",
event.getFile().getFileName() + " is uploaded.");
FacesContext.getCurrentInstance().addMessage(null, msg);
} catch (IOException e) {
FacesMessage error = new FacesMessage("The files were not uploaded!");
FacesContext.getCurrentInstance().addMessage(null, error);
}
}
}
Now the handling method I got it from a site. I am not sure why this is failing to upload. it looks okay to me. Maybe am missing something? so the control appears on my page and I can choose file, but then upload progress bar just proceeds fast...no growl notification shows and also no file uploaded of course.
Thanks,
From the docs (Assuming using Primefaces)
First thing to do is to configure the fileupload filter which parses the multipart request. FileUpload filter should map to Faces Servlet.
<filter>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<filter-class>org.primefaces.webapp.filter.FileUploadFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>PrimeFaces FileUpload Filter</filter-name>
<servlet-name>Faces Servlet</servlet-name>
</filter-mapping>
Hope you are not missing this setting.
Also not sure whats event in your code
<p:fileUpload fileUploadListener="#{uploadBean.handleFileUpload(event)}" .....
