i have a simple problem here
i am making a simple jsf web app that can upload file
but i kept getting
Target Unreachable, identifier 'upload' resolved to null
here's my upload class
package SimpleLogin;
import java.io.IOException;
import javax.faces.application.FacesMessage;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import javax.faces.context.FacesContext;
import org.apache.commons.io.FilenameUtils;
import org.apache.myfaces.custom.fileupload.UploadedFile;
#ManagedBean
#RequestScoped
public class upload {
private UploadedFile uploadedFile;
public void submit() throws IOException {
String fileName = FilenameUtils.getName(uploadedFile.getName());
String contentType = uploadedFile.getContentType();
byte[] bytes = uploadedFile.getBytes();
FacesContext.getCurrentInstance().addMessage(null,
new FacesMessage(String.format("File '%s' of type '%s' successfully uploaded!", fileName, contentType)));
}
public UploadedFile getUploadedFile() {
return uploadedFile;
}
public void setUploadedFile(UploadedFile uploadedFile) {
this.uploadedFile = uploadedFile;
}
}
and my index page

what is the problem ? do i not clearly state the upload class ?
Any help is good :)
You have overridden the #ManagedBean by a <managed-bean> declaration on the faces-config.xml, however that <managed-bean> declaration has a different managed bean name, namely bean instead of upload.
You have basically 3 options:
Use #{bean} instead of #{upload} in your view.
Rename the <managed-bean-name> in faces-config.xml from bean to upload so that you can use #{upload} in your view.
Get rid of <managed-bean> altogether so that the #ManagedBean will be used. The managed bean name defaults to the bean class name with 1st char lowercased, thus #{upload} should work.
For the remaining, you are not consistent with Java naming conventions. Please work on that as well. Package names should be all lowercase and class names should be CamelCase and start with uppercase.

I'm using Jakarta EE 9, Glassfish 6.0, and JSF 3.0 and getting "Target Unreachable, identifier '' resolved to null..." I know questions like this have been asked before but I tried all proposed solutions. Also, I could find very few discussions about version 3.0 of JSF. I would appreciate it if someone could help me spot what wrong is.

It is because of Application Server that cannot fully support to JSF-3.0. I've got same error when I tested jakartaee-tutorial-examples/web/jsf/guessnumber-jsf project. I've tried guessnumber-jsf.war file on WildFly 24.0.0.Final and wildfly-23.0.2.Final Application servers. I got same error on both servers. But when I tested on Wildfly-preview-23.0.2.Final which supports JakartaEE 9.1 and JDK 11, it is working well.
I am building a web application that uploads files and am trying to add CDI features that require the use of a beans.xml file. The problem is that when I add a beans.xml file to the webapp it breaks the previously functional input file uploading, even before I switch over to any features that require beans.xml. Why is even the presence of a beans.xml file breaking this feature?
Environment and Dependencies:
JDK 1.7.0_45
Netbeans IDE 7.4 Patch 2
Windows 7 version 6.1 running on x86
javaee-web-api-6.0
primefaces-3.5
tomahawk-1.1.14
GlassFish Server 4.0
Here's the code if that will help:

GlassFish 4 ships with JSF 2.2 which has already a native file upload support in flavor of <h:inputFile>. The FacesServlet has already processed the uploaded file before it hits Tomahawk's <t:inputFileUpload>.
You have basically 2 options:
Get rid of Tomahawk and use native file upload component <h:inputFile> instead.
<h:form enctype="multipart/form-data">
<h:inputFile value="#{bean.uploadedFile}" />
...
</h:form>
with
import javax.servlet.http.Part;
// ...
private Part uploadedFile; // +getter +setter
Downgrade from JSF 2.2 to JSF 2.1 or 2.0. Downgrading the whole server as you did is one way, albeit somewhat clumsy.
I ended up switching to Glassfish Server 3.1.2.2 and the problem was solved.
I am using JSF 2.2.4 on GlassFish 3.1.2.2.
I have this backing bean:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import java.io.Serializable;
#ManagedBean(name="testMB")
#RequestScoped
public class TestMB implements Serializable {
public long id;
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
}
And this view test.xhtml:
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<f:metadata>
<f:viewParam name="id" value="#{testMB.id}"/>
</f:metadata>
<h:body>
<h:inputText value="#{testMB.id}" />
</h:body>
</html>
When I open /test.html?id=123, then the ID shows up as 0 instead of 123. Why didn't <f:viewParam> do its job?
Updated
I installed GlassFish 4.0.
Maven dependencies for JSF:
<dependency>
<groupId>javax.faces</groupId>
<artifactId>javax.faces-api</artifactId>
<version>2.2</version>
</dependency>
faces-config.xml:
<?xml version='1.0' encoding='UTF-8'?>

<!-- JSF and Spring are integrated -->
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>

And test.xhtml:

xmlns:f="http://xmlns.jcp.org/jsf/core"

</f:metadata>
<h:body>
<h:inputText value="#{testMB.id}" />
</h:body>
</html>
But the ID shows up as 0.
Maven project for test:
https://www.dropbox.com/s/qbc05vysspvt46l/jsf-spring-mybatis-master.zip
Problem solved
Pages named as *.xhtml.
In web.xml was:
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.html</url-pattern>
</servlet-mapping>
Right:
<url-pattern>*.xhtml</url-pattern>
I was trying to create a secure login page with jsf, and I used these code snippets as the solution, found in this question. My problem is, that I can access the /restricted/secret.xhtml without logging in, there is no redirect it's like the filter is not applied, because if I go directly to the /restricted/secret.xhtml the #{user.loggedIn} evaluates to false and I still can view the page. Here is my code:
AuthFilter.java
public class AuthFilter implements Filter {
private FilterConfig config;
#Override
public void destroy() {
this.config = null;
}
#Override
public void doFilter(ServletRequest req, ServletResponse resp,
FilterChain ch) throws IOException, ServletException {
HttpSession s = ((HttpServletRequest) req).getSession();
if (s.getAttribute(UserBean.CREDENTIAL)==null)
{
((HttpServletResponse) resp).sendRedirect("/login.faces");
}else
{
ch.doFilter(req, resp);
}
}
#Override
public void init(FilterConfig config) throws ServletException {
this.config = config;
}
}
UserBean.java
#ManagedBean(name="user")
#SessionScoped
public class UserBean implements Serializable {
private String name;
private String password;
protected static final String CREDENTIAL = "ontherun";
private static final long serialVersionUID = 1L;
public String getName()
{
return this.name;
}
public void setName(String newName)
{
this.name = newName;
}
public String getPassword()
{
return this.password;
}
public void setPassword(String newPassword)
{
this.password = newPassword;
}
public boolean isLoggedIn()
{
return FacesContext.getCurrentInstance().getExternalContext()
.getSessionMap().get(CREDENTIAL) != null;
}
public String logout() {
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().remove(CREDENTIAL);
return null;
}
public String login()
{
FacesContext.getCurrentInstance().getExternalContext().getSessionMap().put(CREDENTIAL, this.name);
return "secret";
}
}
Here is my login.xhtml ; the page works correctly, so there is no problem with the template file.

My directory structure looks like this: dirStruct 2
You've mapped FacesServlet on /faces/* instead of *.xhtml. So all JSF requests will have the /faces prefix in the URL. But you've mapped the AuthFilter on /restricted/* instead of /faces/restricted/*, so it will never kick in on /faces/* URLs.
You can solve this in 2 ways:
Map FacesServlet on *.xhtml instead of on /faces/*. This has the additional advantage that the enduser won't ever be able to see the raw JSF source code when the enduser purposefully removes the /faces path from the URL in browser address bar.
Map AuthFilter on /faces/restricted/* instead of on /restricted/*.
I personally recommend the first way. You end up with a shorter and nicer URL and you immediately also prevent the JSF source code leak.
I am to do a web application with JSF, just to get and put a value from the JSF to bean and vice versa. I think I have done everything properly but when I start the server and try to access my first page I get the following error
SEVERE: Servlet.service() for servlet [jsp] in context with path [/SimpleJSF] threw exception [/greeting.jsp (line: 20, column: 85) #{...} is not allowed in template text] with root cause
org.apache.jasper.JasperException: /greeting.jsp (line: 20, column: 85) #{...} is not allowed in template text
I am using Eclipse Helios with JDK 1.6 , apache Tomcat 7 and JSF 2.0 framework

In JSF 2.0, JSP is been deprecated as view technology and succeeded by Facelets. You need to rename your .jsp files to .xhtml files. In your case you also need to remove the entire <%# page %> line in both JSPs. Then you need to invoke them with the .xhtml extension in the URL.
Further, you also need to remove the ConfigureListener from web.xml and you need to rename the JSP welcome file to XHTML. I'd also suggest to use *.xhtml instead of /faces/* as FacesServlet URL pattern. This way you don't need to put a /faces/* in URLs everytime. Finally you need to remove the bean from faces-config.xml and annotate the bean as follows instead of those javax.ejb annotations:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
#ManagedBean
#RequestScoped
public class ResultNumber {
After all, it seems that you were reading JSF 1.x tutorials and mixing it up with JSF 2.x. You should be extremely careful what JSF version the JSF book/tutorial you're reading target. Since JSF 2.0 a lot of things are done differently.
You are using .jsp files,so you should import the taglibs manually.Add these two lines right above your opening html tag.
<%# taglib uri="http://java.sun.com/jsf/core" prefix="f"%>
<%# taglib uri="http://java.sun.com/jsf/html" prefix="h"%>
