I want to share my experience with this Exception. My JSF 2.2 application worked fine with WildFly 8.0, but one time, when I started server, i got this "Target Unreacheable" exception. Actually, there was no problem with JSF annotations or tags.

Only thing I had to do was cleaning the project. After this operation, my app is working fine again.

One day I was debugging and my working project started throwing this error, out of the blue. Restarting the Glassfish server fixed it.

You got the wrong import - the @SessionScoped is from the faces package, it should be the one from the javax.enterprise.context package.

Or you can switch @Named to @javax.faces.bean.ManagedBean, then the @SessionScoped will match (it will no longer be a CDI bean though).

private Locale locale = FacesContext.getCurrentInstance().getViewRoot().getLocale();

@Kukeltje: if everyone did it, there would be no StackOverflow as we know it :-)

By the way when I switch the JSF pages into the war package(all other beans are in ViewScope) are these properties going to be preserved?

In h:outputLabel, the for attribute must evaluate to String in an earlier phase of the JSF lifecycle than when the expression "#{userbean.userName}" can be evaluated. Therefore, you need to give it a String value like this:

<h:outputLabel for="userName" value="UserName" />
<h:inputText id="userName" value="#{userbean.userName}" label="UserName"/>

See this link about JSF lifecycle:

Restore View Phase During this phase, the JavaServer Faces implementation builds the view of the page ... If the request for the page is an initial request, the JavaServer Faces implementation creates an empty view during this phase and the lifecycle advances to the Render Response phase, during which the empty view is populated with the components referenced by the tags in the page.

So, the bean value is evaluated not before the Render Response phase, when the (empty) view has already been built.

Have changed the code as you said. but still getting same error after click the button

And you have changed correspondingly the second <h:outputLabel> for the <h:inputSecret>, I guess.

Hi All, Thanks a lot have resolved the issue i just run it with maven goal tomcat:run-war instead of tomcat:run

good call Shankar, this worked for me also this is my run command in total "clean install tomcat7:run-war" If anybody can explain why this fixes this particular problem, it would be helpful

The Java naming conventions state that instance variable names starts with lowercase. You need to use #{generate.viewReportPDF} instead of #{Generate.viewReportPDF}.

If you really insist in using a capitalized instance variable name (which is bad), then you can always override it in the @ManagedBean annotation:

@ManagedBean(name="Generate")
@SessionScoped
public class Generate {

Note that I added the @SessionScoped annotation, you forgot that. You should also remove that superfluous and old fashioned managed bean configuration in faces-config.xml which would only clash with the annotations and override them. I would also recommend using Facelets instead of the ancient JSPX.

Thanks for the help but it still doesn't work, I added @SessionScoped and I renamed #{Generate.viewReportPDF} to #{generate.viewReportPDF}. And now i have the same error with generate instead of Generate.

My bad ! I removed the managed bean configuration in faces-config.xml and everything work now ! Thanks

Your bean is really not a CDI bean I guess your problem is caused by mixing up the imports. So try

@javax.inject.Named //defaults to "indexMB"
 @javax.enteprise.context.RequestScoped
 public class IndexMB {
      //rest of your class here
 }

order
#{orderBean.onRowSelectNavigate}

and

#{order.onRowSelectNavigate}

Your OrderBean is a class name, but order is the name how you will access those beans in expressions of EL. These are no two beans. First is name of your class (type) second is the name of instance you are working with.

You are missing a listener to start the Spring Container:

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

Since you have the JSF FacesServlet, you might need the RequestContextListener as well:

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

the first was already in place, missed to mention it. The second wasn't, i added it but the error is the same. I suppose that there is something in the way i created the bean

can you add the output of the Spring Context initialization logs?

you'll have to add a log4j.properties in your classpath in order to direct the DEBUG logs to something (your IDE's console, a file, email, etc). here's an example.

i put the log4j.properties file in the root folder for .java files. Then ive copied all the server log to console and updated the Question. hope it's wath you intended.

The <p:contentFlow> is not an UIData component. It is thus not capable of saving and restoring the iteration state during a component tree visit (as required during decode of UICommand component). You'd basically need to print image's unique identifier as a HTTP request parameter during render response.

<p:commandButton icon="ui-icon-trash"
                 action="#{imageHandler.deleteImage}"
                 update="contentFlow">
    <f:param name="id" value="#{i.id}"/>
</p:commandButton>
public void deleteImage() {
    String i = FacesContext.getCurrentInstance().getExternalContext().getRequestParameterMap().get("id");
    this.imgFacade.deleteImage(i);
}

First of all thank you.Well I had already tried this solution, but I re-checked to see if I had placed something wrong and I still get the same error.

I now see that you've placed the command button inside the image. This will result in invalid HTML. Separate them, or use a command link and put the image inside the command link.

What is weird is that I already use the <f:param a couple lines of code before and this works perfectly for this is how the images are rendered.

The f:param is only applied on the parent. So your current f:param is only applied on the image, not on the command. The command must have its own, exactly as shown in the answer.

The error is still shown when clicking the commandButton even placed out of graphicImage, I update question with these details.

I want to share my experience with this Exception. My JSF 2.2 application worked fine with WildFly 8.0, but one time, when I started server, i got this "Target Unreacheable" exception. Actually, there was no problem with JSF annotations or tags.

Only thing I had to do was cleaning the project. After this operation, my app is working fine again.

right click on server > clean didn't work for me. I dunno if it what made it work but I clicked restart on the project (not the server).

It happened to me a few times, sometimes cleaning the project solved it and sometimes restarting glassfish worked

Had the same issue, for me restarting and cleaning didn't work. But after restarting Eclipse everything went back to normal

Mine was the same issue, except I had to stop the server, clean the server and restart it.

The problem seems related to the double configuration of your managed bean with the same name:

  • Annotation configuration by using @ManagedBean and @SessionScoped annotations on the class called user.
  • XML configuration in faces-config.xml file through the <managed-bean> node called User.

You should have a single configuration per managed bean i.e. the name. In this case, since you basically have the same managed bean configured twice, just remove one of the configurations. I recommend removing the XML configuration since the annotation configuration is more readable and understandable.
