Load file into textarea from uploaded files in primefaces

Question

I would like to display text file into textarea in primefaces.

Following user define steps are:

1. Click on Upload control (user can upload multiple files)
2. I am fetching all uploaded files and displaying file name in radio button
3. From radio buttons, User will select one of the file and that file will load into textarea.

While performing 3rd steps, I am getting following error

java.io.FileNotFoundException: C:\Users\UserName\Workspace\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\work\Catalina\localhost\ProjectDummy\upload_d8a75697_ad88_43fe_acd8_8133bf93d727_00000017.tmp (The system cannot find the file specified)

Following is the code: Xhtml code:

<h:form method="POST" enctype="multipart/form-data"

                    <p:growl id="messages" showDetail="true" />

                        <br />
                        <br />

                        <p:selectOneRadio id="console" value="#{backingBean.fileName}"
                            layout="grid" columns="1">

                        </p:selectOneRadio>

                        <p:commandButton value="Load" action="#{backingBean.loadFile}"
                            ajax="false" update="txtInput" process="@all" style="width:80px"></p:commandButton>
                        <br />
                        <br />
                        <p:inputTextarea id="txtInput" value="#{backingBean.fileText}"
                            rows="10" cols="50">
                        </p:inputTextarea>
                    </p:panelGrid>

                </h:form>

BackingBean.java

public void handleFileUpload(FileUploadEvent event) throws IOException, NotSerializableException {

        li = new ArrayList<UploadedFile>();
        li.add(event.getFile());
        setLi(li);
        ListIterator<UploadedFile> list = li.listIterator();
        while (list.hasNext()) {
            String str = event.getFile().getFileName();
            System.out.println(str);
            ++count;
            fileNames.add(str);
            fileList.add(event.getFile());
            list.next();
        }
    }

    public void loadFile() throws IOException, NotSerializableException {
        String filenameRadio = getFileName();
        for (int i = 0; i < count; i++) {
            String fileS = fileList.get(i).getFileName();

            if (fileS.equalsIgnoreCase(filenameRadio)) {
                setUploadedFile(fileList.get(i));
                InputStream is = getUploadedFile().getInputstream();
                int read = 0;
                byte[] bytes = new byte[(int) fileList.get(i).getSize()];

                String s1;
                while ((read = is.read(bytes)) != -1) {
                    s1 = new String(fileList.get(i).getContents());
                    setFileText(s1);
                    System.out.println(getFileText());
                }
                is.close();
            }
        }
    }

Could help me to solve this error ?
