I've read #EJB in #ViewScoped managed bean causes java.io.NotSerializableException, but my state saving setting is server.
Here is what I have:

I know I can workaround this by declaring PersonFacade as transient and use JNDI to get EJB reference after recontruction, but I really dislike this approach.
Is it possible that Glassfish 3.1.1 provides non-serializable EJBs? Is there a way to use #EJB and #ViewScoped together?
update:
i found that this is a MyFaces related issue, all is working fine using mojarra
I have seen the problem too. What I have done in the past is split my bean into a StateBean which is #ViewScoped and an ActionsBean which is #RequestScoped. The ActionBean is injected with the StateBean as well as any EJBs or non-serializable resource accessing objects. On the front-end you use the StateBean for accessing properties and ActionsBean for performing actions.
I would love to hear from someone else who would make my "bean splitting" pattern deprecated.
This is an example of what I do:
#ManagedBean
#ViewScoped
public class CustomControllerStateBean implements Serializable {
private static final long serialVersionUID = 134755304347034L;
private Person selected;
public Person getSelected() {
return selected;
}
public void setSelected(Person selected) {
this.selected = selected;
}
}
Notice CustomControllerStateBean is #ViewScoped and is Serializable an only contains Serializable objects.
#ManagedBean
#RequestScoped
public class CustomControllerActionsBean {
#EJB
private PersonFacade facade;
#Inject
private CustomControllerStateBean state;
public void create() {
facade.create(state.getSelected());
}
}
Notice CustomControllerActionsBean is #RequestScoped and is NOT Serializable an contains non-Serializable objects.
Your front-end will no look like this:
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"

</f:facet>
<h:panelGrid columns="3">
<h:outputLabel for="name" value="#{bundle['person.name']}"/>

<p:message for="name"/>
<h:outputLabel for="surname" value="#{bundle['person.surname']}"/>

<p:message for="surname"/>
</h:panelGrid>
</p:panel>
</h:form>
</h:body>
</html>
Notice CustomControllerActionsBean is used at the top in the p:commandButton and CustomControllerStateBean is used in the p:inputTexts.
:) I had the same problem: https://issues.apache.org/jira/browse/MYFACES-3581
David Blevins over at the Apache TomEE helped me a log a bug and patch for MyFaces. The problem was generated proxy classes aren't on the classloader path for their deserializer.
A workaround is to set this web-app param to false: org.apache.myfaces.SERIALIZE_STATE_IN_SESSION

I am trying to show the Alien Object in XML format with AlienResouces as Resource.However, it is giving me 404 error during runtime on the browser and the debugging stmnt GeAlien called is not showing on Tomcat console
Web Service
package com.dip.testproj;
import javax.xml.bind.annotation.XmlRootElement;
#XmlRootElement
public class Alien {
private String name;
private int points;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getPoints() {
return points;
}
public void setPoints(int points) {
this.points = points;
}
}
The following is the Resource for the Alien object. The object Alien is getting the resource Name and Number and trying to display it on the browser during runtime.
We Service Resources
package com.dip.testproj
import javax.ws.rs.Path;
import javax.ws.rs.GET;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
#Path("aliens")
public class AlienResources {
#GET
#Produces(MediaType.APPLICATION_XML)
public Alien getAlien(){
System.out.println("getAlien Called");
Alien a1 = new Alien();
a1.setName("Navin");
a1.setPoints(60);
return a1;
}
}
There is no compilation error or any error on the console for Tomcat. server. However, it is giving "404" or "Resource could not be found" while trying to run the THIS on the FF browser

I've configured my project to load at this URL:
http://localhost:7101/foo/rs/user/home
However, when I deploy the application through JDeveloper I can see this in the Debugging: IntegratedWebLogicServer tab within the IDE:
Target Application WADL -- http://localhost:7101/foo/application.wadl
Target URL -- http://localhost:7101/foo/user/home
Note the /rs part is missing. It's mostly cosmetic (the site loads correctly in the browser when you use the correct URL) but, apart from confusing, it might be a symptom of some configuration issue. Where does JDeveloper get this URL from?
These are some of the hopefully relevant settings:
\ViewController\ViewController.jpr

<value n="j2eeWebAppName" v="Foo-ViewController-webapp"/>
<value n="j2eeWebContextRoot" v="foo"/>

Hi i have a Red5 Application Server running and a NetConnection using Air to IOS to connect to the Red5 Application Server.
But the problem is that i get an error like:
2014-07-01 04:43:04,475 [NioProcessor-6] ERROR o.r.server.service.ServiceInvoker - Method addSomething with parameters [2, 3] not found in org.red5.server.CoreHandler#ebf5a1
I understand that the Method is not being called for some reason but can understand why, can anyone help please?

The issues is that the "numbers" are not coming to the server as the expected type of "double". There are several solutions to this:
Change the parameter type on your addSomething method to int.
Send your parameters from the client with a decimal point (2.0 vs 2)
This is my class:
package pkg.rest;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import com.sun.jersey.core.header.FormDataContentDisposition;
import com.sun.jersey.multipart.FormDataParam;
#Path("/file")
public class UploadFileService {
#POST
#Path("/upload")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(
#FormDataParam("file") InputStream uploadedInputStream,
#FormDataParam("file") FormDataContentDisposition fileDetail) {
String uploadedFileLocation = "d://uploaded/"
+ fileDetail.getFileName();
// save it
writeToFile(uploadedInputStream, uploadedFileLocation);
String output = "File uploaded to : " + uploadedFileLocation;
return Response.status(200).entity(output).build();
}
// save uploaded file to new location
private void writeToFile(InputStream uploadedInputStream,
String uploadedFileLocation) {
try {
OutputStream out = new FileOutputStream(new File(
uploadedFileLocation));
int read = 0;
byte[] bytes = new byte[1024];
out = new FileOutputStream(new File(uploadedFileLocation));
while ((read = uploadedInputStream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
this is my Html File for uploading :

when i try to upload file to server then no action perform i dint create client direct run it html file in tomcat server and try to access it please help me what we need to do change this i am writing first time so please help .
You didn't put enough stuff in web.xml, so the container does not know how to route request to your Jersey servlet.
Add the following to your web.xml:
<servlet>
<servlet-name>UploadServlet</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>pkg.rest</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>UploadServlet</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
You need to have the pattern /rest/* in all the url's which you want to be handled as a service.
I am trying to run this simple example on eclipse .As i run the server it is not showing any error .But in the browser it is showing 404 error page not found. I don't understand what is the error.I have used all the Jars in my WEB-INF/Lib folder too.

It sounds like you are using the wrong url. Tomcat generally has a folder called webapps for applications that are deployed on that server. To figure out the configuration, in Eclipse, open up the Server tab, find your Tomcat server and double-click on it.
It should bring up a properties pane with two tabs at the bottom Overview and Modules. Click on Modules and you should see the path to your app. For me, it's in the form of: /webapps/<project name>
Your full url would be localhost:8080/webapps/<project name>/anystringhere.do since you map anything in your app (localhost:8080/webapps/<project name>/) that ends in .do to the action servlet.
