GetResourceAsStream(String name) return null

Hi!
jdk1.3
I want to get InputStream from file. My code is:
import java.util.*;
import java.io.*;
String path = new String("D:" + File.separator
               + "my_project" + File.separator
               + "test" + File.separator
               + "classes" + File.separator + "test.properties");// I set absolute path to file It's necessary for me
InputStream inputStream = getClass().getResourceAsStream(path);
Properties prop = new Properties();
prop.load(inputStream);
The result is NullPointerException in last row.It's can not find resource. Why?
Thank you

Try FileInputStream

XML Element to string conversion returning null

Hi,
When i try to convert XML Element to string using toString() API, it returns something like [device: null] where device is element tag.
Code is as follows -
Document xmlDoc;
DOMParser parser = (DOMParser)Class.forName("org.apache.xerces.parsers.DOMParser").newInstance();
parser.setFeature( "http://apache.org/xml/features/dom/defer-node-expansion", true );
parser.parse(new InputSource(new StringReader(tableStr)));
xmlDoc = parser.getDocument();
Element root = xmlDoc.getDocumentElement();
NodeList nodeList = root.getElementsByTagName("device");
Element deviceNode = (Element)nodeList.item(nodeList.getLength()-1);
System.out.println(deviceNode.toString()); //prints [device: null] ????
System.out.println(deviceNode.getAttribute("ipAddress")); //prints correct ip address
Any idea why i am getting [device: null] when trying to convert Element to String though attribute value is retrieved.
Thanks,
Deepak

I wrote the following lines of code ..
FTI .. >> String strMsg =((javax.jms.TextMessage)msg).getText();
StrMsg is a string that represents an xml file .
DocumentBuilderFactory docfactory = DocumentBuilderFactory.newInstance();
               DocumentBuilder builder = docfactory.newDocumentBuilder();
               Document doc = builder.parse(new InputSource(new StringReader(strMsg)));
               Element root = doc.getDocumentElement();
               System.out.println("The root is " + root);
               String strFileName = root+".xml" ;
               System.out.println("The file name is " + strFileName);
               File f = new File (strFileName);
               FileOutputStream fos = new FileOutputStream( f );
               for ( int j =0 ; j < strMsg.length(); j++)
                    char c = strMsg.charAt(j);
                    fos.write((int)c);
I am getting the following error ...
The root is [ZTOP60_XML_TAG_STRUCTURE: null]
The file name is [ZTOP60_XML_TAG_STRUCTURE: null].xml
Whey the file name or root is with special character [ ] and null ..
I want just ZTOP60_XML_TAG_STRUCTURE.xml .
Can anyone help me .
thanks

GetResourceAsStream(String name) - how to use it?

I tryed to read from a "res.txt" file some text data. This is a test app:
public class ResTest extends MIDlet{
     public void startApp(){
          try{
               InputStream is=new String().getClass().getResourceAsStream("/res.txt");
               DataInputStream dis=new DataInputStream(is);
               System.out.println(dis.readUTF());
          }catch(Exception e){System.out.println(e);}
     public void destroyApp(boolean bool){}
     public void pauseApp(){}
All I got was EOFException.
So I tryed a different way to read data usinf a loop:
               char ch;
               while((ch=dis.readChar())!=-1){
               System.out.print(ch);
And than I got:
??????java.io.EOFException
The data in "res.txt" file (I put this file to "res" direction of my project, I use KToolbar):
Jajko
Banan

I'm guessing that the res.txt file is a basic ASCII file, right?
If this is the case then that is your problem. When you used readUTF() the implementation was expecting a string in UTF format and not basic ASCII so it didn't know how to read it.
And when you used the readChar() method you have to remember that Java is a Unicode language so chars are 2 bytes. If the string has an odd number of characters then the last character won't have the 2 bytes and you will get an EOFException. And even if the number of chars was even, you wouldn't get the exception but the text wouldn't be what you expect since it was reading text encoded in single byte ASCII format.
You have two choices:
a) Encode the res.txt file appropiately, either save as as a UTF-8 file and use readUTF(), or a Unicode file and use the readChar() method.
b) Use readByte() instead of readChar() and save the bytes in an array, then pass that array to a string constructor.

EJBs cannot return null when used in Model?

Hi,
hopefully this question is in the right place.
I´ve spent now a few days on tracking a single problem. I am trying to create an web dynpro application with the functionality contained in EJBs. One of my methods in a stateless SessionBean returns an object or null. This SessionBean is bound via model binding to the context of a component controller. Everything works fine as along as the method call returns an object, but if it does not (which is the usual case) the application throws an empty exception without any description. Thanks to this forum i checked the defaultTrace log and found this information:
[EXCEPTION]

The request has the cardinality 1..1, the response 0..1 and the return value 1..1. The last one cannot be changed.
Is that correct that an EJB method call must return an valid object or do i have to change something in order to allow the return of null? Or is this a bug?
Thanks for any answer in advance

Hi,
what are you returning? Objects or basic types? When the methods says it returns a string, a null object is no problem. Btw. i cannot set the cardinality of the of the return node. It´s fixed as 1..1.
My session bean looks so
@Stateless(name="TestBean")
@WebService
public class TestBean implements TestLocal {
     public int add(int zahl1, int zahl2)
          return zahl1 + zahl2;
     public String concat(String text1, String text2)
          return text1.concat(text2);
     public String zeroString(String text1)
          return null;
     public User zeroUser(String text1)
          return null;
The WDP Controller Method looks like this
public void doejbtest( ) {
    //@@begin doejbtest()
       try
            IZeroStringRequestElement req = wdContext.currentZeroStringRequestElement();
            Request_TestLocal_zeroString obj = req.modelObject();
            req.setText1("test");
            obj.execute();
            wdComponentAPI.getMessageManager().reportWarning("String request was successful");
       catch(Exception e)
            wdComponentAPI.getMessageManager().reportException("String request failed");
            wdComponentAPI.getMessageManager().raisePendingException();
       try
            IZeroUserRequestElement req = wdContext.currentZeroUserRequestElement();
            Request_TestLocal_zeroUser obj = req.modelObject();
            req.setText1("test");
            obj.execute();
            wdComponentAPI.getMessageManager().reportWarning("User request was successful");
       catch(Exception e)
            wdComponentAPI.getMessageManager().reportException("User request failed");
            wdComponentAPI.getMessageManager().raisePendingException();
    //@@end
The result of the call is
Warning: String request was successful
Error: User request failed
The Cardinalities are:
Request Cardinality : 1..1
Response Cardinality : 0..1
Return Cardinaliy : 1..1 (no value for the string, fixed for the user)

BPEL Process Manager says that My Simple Web Service returns null !

Hi every body,
I am deploying a process which invokes a simple web service (TheaterWS) running on Tomcat.This service simply accepts a string input and returns it concatenated with other string . I tested it with a client that I made with JDeveloper, every thing is O.K, But after deploying the process to a BPEL server, I got the following Assign Activity error on BPEL Console:

I apprecitae any hints,

Get attribute name from VO returns null.

Hello,
I'm using JDeveloper 11.1.1.3. I have an af:inputfile component in which i set a ValueChangeListener. I'm using the attribute "Filename" from the form view to set the name of the file before saving it to a directory. At first, i had a different layout for my jspx page (very similar in design) and everything was working perfectly. When i redesigned the page, i'm now getting "null" as the filename. I'm not able to get the attribute! Although i didn't change anything in the code! I tried writing a simple method to output the attribute:
      public String justOutput(){
        BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
        AttributeBinding attr = (AttributeBinding) bindings.getControlBinding("Filename");
        if (attr == null)
            return null;
        String filename = (String) attr.getInputValue();
        System.out.print(filename);
        return null;
      }It was able to output the attribute. But in my original method i'm getting "null".
******Another important observation*******
If i pressed upload another time at runtime and uploaded another file it works again!
Here is my code:
     public void uploadFile(ValueChangeEvent valueChangeEvent) {
          InputStream in;
          FileOutputStream out;
          ExternalContext context = FacesContext.getCurrentInstance().getExternalContext();
          String fileLoc = context.getInitParameter("DATA_DIR");
          UploadedFile file= (UploadedFile)valueChangeEvent.getNewValue();
          boolean exists = (new File(fileLoc)).exists();
          if(!exists){
            (new File(fileLoc)).mkdirs();
          if(file != null && file.getLength() > 0){
            FacesContext context2 = FacesContext.getCurrentInstance();
            FacesMessage message = new FacesMessage("File Uploaded" + file.getFilename() +
                                                    "(" + file.getLength() + "bytes)");
            //context2.addMessage(valueChangeEvent.getComponent().getClientId(context2), message);
            BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
            AttributeBinding attr = (AttributeBinding) bindings.getControlBinding("Filename");
            if (attr == null)
                return;
            String filename = (String) attr.getInputValue();
            try {
                     out = new FileOutputStream("C:\\demos\\" + filename + ".pdf");
                     in = file.getInputStream();
                     for (int bytes=0; bytes < file.getLength(); bytes++) {
                         out.write(in.read());
                     in.close();
                     out.close();
                 } catch (IOException e) {
                 e.printStackTrace();
          else {
              String filename = file != null ? file.getFilename():null;
              String byteLength = file != null ? "" + file.getLength():"0";
      }I don't think the code is wrong because it worked before. But why is this happening?
Can anyone please help!?
Mohamed.

Sorry for the late reply Frank,
Thanks for your reply, no i didn't! But it worked when i set the 'autosubmit' property to true... Like you said:
the name field hasn't updated the model to the time you try and access itThanks again.

ObjectInputStream() returning null and EOFException - need help

I have been working on this little snippet of code all day and I cannot understand why I get null values when I run a display application. The code is posted below for 3 file. PhoneList.java is for serialization. CreatePhoneList is to populate a saved file with phone numbers and names of contacts. DisplaySavedPhoneList.java is to display the saved names and numbers. I'm not looking for the correct code, put for someone to point me in the right direction on why I'm getting these results so I can find a solution.
Here is the PhoneList class:
import java.io.*;
public class PhoneList implements Serializable
    private String name;
    private String num;
    private String phName;
    private String phNum;
    PhoneList(String phNum, String phName)
        setName(phName);
        setNum(phNum);
    public String getName()
        return phName;
    public String getNum()
        return phNum;
    public void setName(String phName)
        name = phName;
    public void setNum(String phNum)
        num = phNum;
}Here is the CreatePhoneList class
import java.io.*;
import java.util.*;
public class CreatePhoneList
    public static void main(String[] args) throws IOException
        ObjectOutputStream output = new ObjectOutputStream(new FileOutputStream("PhoneList.txt"));
        PhoneList list;
        String phName;
        String phNum;
        final String QUIT = "QUIT";
        Scanner in = new Scanner(System.in);
        System.out.println("Enter a phone number or " + QUIT + " to quit.");
        phNum = in.next();
        while(!phNum.equals(QUIT))
            System.out.println("Enter the contact name.");
            phName = in.next();
            list = new PhoneList(phNum, phName);
            output.writeObject(list);
            System.out.println("Enter a phone number or " + QUIT + " to quit.");
            phNum = in.next();
        output.close();
}and this is the DisplaySavedPhoneList class:
import java.io.*;
import java.util.*;
public class DisplaySavedPhoneList
    public static void main(String[] args) throws IOException, ClassNotFoundException
        ObjectInputStream input = new ObjectInputStream(new FileInputStream("PhoneList.txt"));
        PhoneList list;
        final int SHOW = 1;
        int showList;
        int count = 0;
        Scanner in = new Scanner(System.in);
        try
            System.out.print("To display Phone List enter " + SHOW);
            showList = in.nextInt();
            while(showList == SHOW)
                list = (PhoneList)input.readObject();
                System.out.println("Name: " + list.getName() + " Phone Number: " + list.getNum());
                count++;
        catch(EOFException e)
            System.out.println("Oops, something broke!");
            input.close();
}This is the result from running the DisplaySavedPhoneList application:

Oops, something broke!

ok, I did that, and its pointing me to the line commented below. I did a practical exercise where the code was almost identical and it worked fine. The only difference are the variables.
try
            System.out.print("To display Phone List enter " + SHOW);
            showList = in.nextInt();
            while(showList == SHOW)
                list = (PhoneList)input.readObject(); //this is the line that was identified in the stacktrace
                System.out.println("Name: " + list.getName() + " Phone Number: " + list.getNum());
                count++;
        catch(EOFException e)
            System.out.println("Stack Trace");
            e.printStackTrace();
            input.close();
        }here is the total stack trace, in case you were wondering...

Kff.where returns 'null' and causes sql error - looking for a work around

Hello,
I am using BI 5.6.3 in EBS (11.5.10.2)
I have created a kff.where as follows:
<lexical
type="oracle.apps.fnd.flex.kff.where"
name="lp_location_where_clause"
comment="Comment"
application_short_name="OFA"
id_flex_code="LOC#"
id_flex_num=":lp_location_flex_structure"
code_combination_table_alias="loc"
segments="ALL"
operator="BETWEEN"
operand1=":p_location_low"
operand2=":p_location_high"/>
</lexicals>
Everything works fine, as long as I have a values for the p_location_low and p_location_high. However, this is a parameter that comes in from a concurrent program and is optional. When the user doesn't pick a value, :p_location_low is the concatenated delimiters for the location '..'.
When this runs, the kff.where is returning null which causes 'Invalid Relational Operation error' because 'AND null' is not valid.
Warning in the log is :[091910_025232517][][STATEMENT] !!Warning: FlexAPI returns null for 'x_where_expression' lexical definition...
Does anyone have a workaround for this since making the parameter required is not an option for my users?
Thanks for reading.

In your SQL*Plus session, make sure you
SQL> set define offbefore trying to create the Java stored procedure. SQL*Plus assumes that any string that begins with an & is a substitution variable unless you tell it that you have no substitution variables (via set define off).

HelpSet.findHelpSet() returns null, and trapping ID errors

I was having a problem initializing JavaHelp. HelpSet.findHelpSet() was returning null. I searched the forum, and found it was a common problem, but the answers were unhelpful. The answers pointed to a problem with CLASSPATH, but offered little in the way of advice for a newbie like myself on how to deal with it.
A second issue concerns HelpBroker.enableHelpOnButton(). If you feed it a bogus ID, it throws an exception, and there's no way to trap it and fail gracefully. JHUG doesn't provide much in the way of alternatives.
Now, having done a bit of research and testing, I'm willing to share a cookbook formula for what worked for me.
I'm working in a project directory that contains MyApp.jar and the Help subdirectory, including Help/Help.hs. My first step is to copy jh.jar to the project directory.
Next, in the manifest file used to generate MyApp.jar, I add the line:
    Class-Path: jh.jar Help/I'm working with Eclipse, so in Eclipse, I use Project - Properties - Java Build Path - Libraries to add JAR file jh.jar, and Class Folder Tony/Help
I define the following convenience class:
public class HelpAction extends AbstractAction
    private static HelpBroker helpBroker = null;
    private String label = null;
    public HelpAction( String name, String label )
        super( name );
        this.label = label;
    public void actionPerformed( ActionEvent event )
        displayHelp( label );
    public static boolean displayHelp( String label )
        if ( helpBroker == null )
            Utils.reportError( "Help package not initialized!" );
            return false;
        try
            helpBroker.setCurrentID( label );
            helpBroker.setDisplayed( true );
            return true;
        catch ( Exception e )
            Utils.reportError( e, "Help for " + label + " not found" );
            return false;
    public static boolean initialize( String hsName )
        URL hsURL = HelpSet.findHelpSet( null, hsName );
        if ( hsURL == null )
            Utils.reportError( "Can't find helpset " + hsName );
            return false;
        try
            HelpSet helpSet = new HelpSet( null, hsURL );
            helpBroker = helpSet.createHelpBroker();
        catch ( HelpSetException e )
            Utils.reportError( e, "Can't open helpset " + hsName );
            return false;
        return true;
}If you use this class in your own code, you'll want to replace Utils.reportError() with something of your own devising.
Finally, in my GUI class, I use the following:
    JPanel panel = ...
    JMenu menu = ...
    JToolbar toolbar = ...
    HelpAction.initialize( "Help.hs" )
    Action gsAction = new HelpAction( "Getting Started Guide", "gs.top" );
    menu.add( gsAction );
    JButton helpButton = new HelpAction( "Help", "man.top" );
    toolbar.add( helpButton );
    InputMap imap = panel.getInputMap( JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT );
    imap.put( KeyStroke.getKeyStroke( "F1" ), "F1help" );
    ActionMap amap = panel.getActionMap();
    amap.put( "F1help", new HelpAction( null, "man.top" ) );

Sorry, the sixth-from-last line of my example should read,
    JButton helpButton = new JButton( new HelpAction( "Help", "man.top" ) );

Why does getParameter("uri") returns null ???

Hi !
JAVA can be rather frustrating and I have run of of dukes. How about IOU ?
Unfortunately none of the previous questions in the db shed light on my problem.
I am trying to get at the "uri" and I have the following code fragment :
package com.developer;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
import java.io.PrintWriter;
public class proptest extends HttpServlet
public void doGet( HttpServletRequest req, HttpServletResponse resp)
    throws ServletException, IOException
    PrintWriter out = resp.getWriter();
    out.println("Parameter Name: " + req.getParameter("uri"));
public void init() throws ServletException
    // initialie the servlet here. Use ServletConfig object to get
    //    initialization parameters...
    ServletConfig config = getServletConfig();
    // ... more stuff ...
}

Hi!
In case anyone stumbles upon this in the database, I worked aroung it by using req.getRequestURI().
However I still do not know why getParameter() returns null. It would be useful e.g. if you want to display a list of all request params e.g.:
// stub code follows...
java.util.Enumeration enum = rea.getParameterNames();
while (enum.hasMoreElements())
String name = (String) enum.nextElement();
System.out.println("Parameter "+name + " " + req.getParameter(name))
...For me, nope, all nulls. If it works for you , do tell me.
Also if you look at the "bugs db" there seems to be a number of issues concerning getParameter().

Why ResultSet getDate() method returns null when querying .csv file?

Here is the full code:
import java.sql.*;
import java.sql.Types;
import java.sql.Date;
import myjava.support.CachedRowSetMaker;
import javax.sql.rowset.CachedRowSet;
import java.io.IOException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
class jdbc2{
final private String s1="SELECT top 10 [DATE], [ADJ CLOSE] FROM [vwo-1.csv]";
private ResultSet result=null;
private Connection conn=null;
public static void main(String[] args) throws SQLException{
jdbc2 db=new jdbc2();
try {
          Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
          db.conn = DriverManager.getConnection("jdbc:odbc:STOCK_DATA");
          PreparedStatement sql=db.conn.prepareStatement(db.s1);
          db.result=sql.executeQuery();
// check column names and types using the ResultSetMetaData object.
          ResultSetMetaData metaData = db.result.getMetaData();
     System.out.println("Table Name : " + metaData.getTableName(2));
     System.out.println("Field\t\tDataType");
     for (int i = 0; i < metaData.getColumnCount(); i++) {
     System.out.print(metaData.getColumnName(i + 1) + "\t");
     System.out.println(metaData.getColumnTypeName(i+1));
     System.out.print(metaData.getColumnName(1) + "\t"+metaData.getColumnName(2)+"\n");
          while (db.result.next()){
               System.out.print(db.result.getDate("DATE", Calendar.getInstance()));
               System.out.format("\t%,.2f\n", db.result.getFloat("Adj Close"));
catch (Exception e) {
System.out.println("Error: " + e.getMessage());
     finally {
          db.result.close();
          db.conn.close();
Everything works well, until getting to the block
          while (db.result.next()){
               System.out.print(db.result.getDate("DATE", Calendar.getInstance()));
               System.out.format("\t%,.2f\n", db.result.getFloat("Adj Close"));
The getDate("DATE", Calendar.getInstance())); always returns null, instead of the date value in the vwo-1.csv.
Even though I change it to
java.sql.Date d=db.result.getDate("DATE") and convert to String using .toString(), I still gets nulls. The dollar amount in "Adj Close" field is fine, no problem.
The .csv fils is downloaded from YahooFinace.
Can anyone review the code and shed some light as to what I did wrong?
Thanks alot.

Why getResource of jar in classpath returns null?

When i iterate through the jars in the classpath and try to turn them into URL's via the getResources(), they all return null. What am I doing wrong?
(NOTE: It does print out the classpath properly when i print that out)
String classPath = System.getProperty( "java.class.path" );
String delim = System.getProperty( "path.separator" );
String[] locations = classPath.split( delim );
for ( int i = 0; i < locations.length; i++ )
      /* ** It doesn't work with either of these statments: ** */
      //This one tries the full path (e.g. /home/me/test/some.jar)
      //Enumeration en = getClass().getClassLoader().getResources( locations[ i ].substring( locations[ i ] );
      //This one tries to use just the local name of the jar (e.g. test.jar)
      Enumeration en = getClass().getClassLoader().getResources( locations[ i ].substring( locations[ i ].lastIndexOf( '/' ) + 1 ) );
      //This just prints null
      while ( en.hasMoreElements(); ) System.out.println( en.nextElement() );

What you are doing doesn't make sense. The resource locations within a JAR file are relative to the package directory structure within the JAR file, not to its own absolute location on the disk. And you seem to be expecting to retrieve a JAR file from within a JAR file. This makes no sense either.

Why this line of code returns null always??

Dear All,
Just a question.
I have this snippet of code where a user is required to input a number.
<af:panelGroupLayout layout="vertical" id="pgl1">
<af:inputText label="number" id="it1"
                    value="#{MyBean.number}" immediate="true"/>
<af:commandButton text="Submit" id="cb1" partialSubmit="true"
                    immediate="true"
                    actionListener="#{MyBean.handleAction}"/>
</af:panelGroupLayout>The immediate attribute at both inputtext and button are needed as I am bypassing validation on the other form components.
Here is my bean defined in request scope.
public class MyBean
private String number;
public void handleAction(ActionEvent actionEvent)
    AdfFacesContext ctx = AdfFacesContext.getCurrentInstance();
    Map<String, Object> pageFlowMap = ctx.getPageFlowScope();
    pageFlowMap.put("number", getNumber());               //Problem line getNumber is always null
public void setNumber(String number)
    this.number = number;
public String getNumber()
    return number;
}I am having problem on the above line. I always get a null value on the number input text.
Why is that so as I think I have already place a value on my Bean.
For completeness sake, here's how I defined my managed bean
<managed-bean id="__12">
    <managed-bean-name id="__9">MyBean</managed-bean-name>
    <managed-bean-class id="__11">com.testing.MyBean</managed-bean-class>
    <managed-bean-scope id="__10">request</managed-bean-scope>
</managed-bean>Not sure but any workaround to this?
Thanks

Hi, Apparently this does work. Putting a binding on the input components.
But somehow, I am reluctant to make use of any bindings as I am encountering issues when I expose this Taskflow as portlet in a Webcenter Application.
But, as I have read the article, I made changes with the code. I am not using any bindings but just making use of the valuechangelistener.
From the article, I have realized that the reason why the setter method of the bean was not called is because the Update Model Values was skipped.
Very nice article.
Thanks.

A getName method allways returns null, why?

I have an
ArrayList<Animals> array_list = new ArrayList<Animals>();
LinkedList<Animals> linked_list = new LinkedList<Animals>();
I want the getName() method in class NewListener to be accessed from the class NextListener which extends NewListener, and therefor should get access to the method. But when I run the program, it allways returns null. Why?
class NewListener implements ActionListener
          public String name;
          public void actionPerformed(ActionEvent e)
               String str_name = showInputDialog(this,"Animal name: ",null);
               if(str_name == null)
                    return;
               for(int i=0; i<array_list.size(); i++)
                    if(array_list.get(i).getName().equalsIgnoreCase(str_name))
                         setName(str_name);                   // set the name with the setName() method
                         linked_list.add(array_list.get(i));
          public void setName(String name)
               this.name=name;
          public String getName()
               return name;        // this line returns "null"
                     // return "Hello";    // this line works and returns "Hello"
     class NextListener extends NewListener implements ActionListener
          public void actionPerformed(ActionEvent e)
               try
                    linked_list .removeFirst();
               }catch(NoSuchElementException er)
                    System.out.println("Numerical value");
               String info = getName()+" is in line";   // Why does the getName() method in the NewListener allways return a null?
               showMessageDialog(this, info, "Notice", INFORMATION_MESSAGE);
     }{code}

Ok, I changed the name to private and I also tried with
public void setName(String name)
System.out.println("setting name on " + this + " to " + name); // <--- ADD THIS LINE

}and it works. So this.name SHOULD get the value of name, but it doesn�t.
So the question is: why does getName() return null?Your code is doing exactly what you're telling it to do. One or more of your assumptions is wrong. Keep digging. Add more print statements.
Above all, you must drop the attitude that "it should work." There's a bug in your code. You have to find it. Repeating the mantra "It should work" is simply going to put blinders on and make it almost impossible to find your error. Instead, you have to think, "What did I do wrong?" and "If getName is returning null, then setName was never called or was called with null."
