GetImplementation*() methods return null...

I have Implementation-Vendor, Implementation-Version and Implementation-Title clearly defined in my MANIFEST.MF, yet when I try to retrieve them (with e.g. MainClass.class.getPackage().getImplementationVendor()) null is always returned.
Anyone have any idea what the problem might be?
Thanks ahead.

I seem to have found what the problem is. I use one-jar to pack couple of libraries with my project. When I don't pack the application it works like it should but it doesn't when it's, hmm..."one-jarred".
As a side not, I absolutely have to do that (or any other way of accessing libraries from within the jar, but this is the only that works so far and I have to be done in less than a week).
I've searched around one-jar's site and forum and no one seemed to have noticed this problem, so if anyone's got any idea it's much appreciated.

-AndrewDoes it return a null object, or does it return "null" as a String? The latter may be a case of using the message from a wrapped exception, which in case of a NullPointerException is frequently null (if the NPE was not constructed intentionally with a message).

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.

.getGraphics in custom rendering method returns null... anyone know why?

Hello,
The problem is pretty much exactly as specified.
Take this class for example:
* To change this template, choose Tools | Templates
* and open the template in the editor.
package vicsanimation;
* @author
import java.awt.*;
import java.awt.image.*;
import javax.imageio.*;
import java.io.*;
import javax.swing.*;
public class VButton extends JLabel {
    BufferedImage activeImage;
    BufferedImage pressedImage;
    BufferedImage deactiveImage;
    BufferedImage highlightedImage;
    ImageIcon currentImage;
    public VButton (String b1, String b2, String b3, String b4, int x, int y){
        activeImage = new BufferedImage(1,1,BufferedImage.TYPE_INT_ARGB);
        try {
            activeImage = ImageIO.read(new File(b1));
            pressedImage = ImageIO.read(new File(b2));
            deactiveImage = ImageIO.read(new File(b3));
            highlightedImage = ImageIO.read(new File(b4));
        catch (IOException e) {
            System.out.println(e.getMessage());
        this.setSize(activeImage.getWidth(), activeImage.getHeight());
        this.setLocation(x,y);
        this.setVisible(true);
        this.render();      // <----------------- ERROR FROM HERE!!!
    // This is the method used to render the button. It does not use the paint method
    // because the application can use FullScreen mode.
    public void render(){
        Graphics2D buttonGraphics = (Graphics2D)this.getGraphics();
            buttonGraphics.drawImage(activeImage, null, 0, 0);
            System.out.println("Image drawn successfully");
}If I run this code, I get a Null-Pointer exception thrown from the last method. This is because the "buttonGraphics" object is null.
I do know a work-around, although I'd really like to know exactly why this is happening.
The work-around is simply to remove the this.render() call at the end of the constructor, create the button in an outside container object, and then call the render() method from the object that contains the button. For example:
    private void initScreen(){
        ..... snip ....
        VButton closeButton = getCloseButton();
        this.add(closeButton);
        closeButton.render();
        ..... snip .....
    }If anyone could explain to me why this happens (in non-Java expert language) I'd be very thankful.

Thanks again for your help.
I'm sure the solution to every problem is in the API if one were to look hard enough!
But obviously the API is massive and I suppose you learn these things from experience more than committing that kind of stuff to memory. If I were to scour the API looking for solutions to things which I only barely understand to start with I'd go mad. Let alone be there for several days.
So thanks for helping out, I really appreciate it!

GetContextURL returns null using the default ECM repository

Hello experts,
This is the scenario.
We are using the SAP ECM repositoy for document storage in our BPM proyect. In this case we are using the default configuration and repository location (ecm/default and DefaultUser), but after the upload, when i try to get the document URL with the method getContentURL(), returns null.
The ECM documentarion saids than this condition is expected when using a third party repostiory, but this is not the case.
I appreciate a lot your advices and recomendations,
Best regards!
Julio C. Leyva

Hi Vasil,
We didn't resolve this issue by this method, because we are using the default ECM repository witch doesn't support the operation getContextURL() and gets the "null" result. If you are using a different repository maybe works.
Re-checking the API specification, saids:
getContentURL
java.lang.String getContentURL() throws InvalidStateException, RepositoryException Returns a URL that can be used to retrieve the content directly from the respective backend, thus bypassing ECM. Note that this URL might have several restrictions which depend on the connector's backend store, such as a limited lifetime or requiring a user to authenticate with different credentials than the ones used to connect to ECM. Other stores might provide no content URL at all, in which case this method returns null. Applications might want to consider utilizing the ECM WebDAV server to present their users a URL that is located on the same system as ECM.
Finally, you would consider to expose a webservice (EJB Session Bean) witch encapsulates the ECMI implementation and extract your file content as a binary array (encode/decode), sending as the input your path/fileName for lookup in the ECM repository.
Regards!

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
this.name=name;
}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."

How can I return null in a double method

I have a method, and like this:
public double fu(){
In some case I want to return null instead of a double value, how can I make it?
Thanks.

The approach with the wrapperclass works. But you should consider, why you want to return null. Is it just to express that an error occured? Then better throw an exception. Or do you want to return that there cannot be a usefull return. Then try to define a special value for that like -1. Normally there is a better approch then returning null.
public class Doubles {
public static void main(String[] args) {
    double d = 0;
    try {
      d = doIt();
    } catch (DoubleException d) {
      System.err.println("You made an error.");
public static double doIt() throws DoubleException {
    if (allOk)
      return 10.123;
    else if (noUsefullAnswer)
      return -1;
    else if (bigError)
      throw new DoubleException("You made a mistake, dummy.");
public class DoubleException extends Exception {
public DoubleException(String s) {
    super(s);
}

EJB P.R.O.narrow method returns a null reference though object is valid

All,
I'm trying to deploy a simple stateless session bean to SUN server. The client code keeps failing because PortableRemoteObject.narrow returns null, even though the reference is located in JNDI tree.
I read somewhere that turning on RMI stub generation might help, but it didn't do it in my case.
This is a local server (SUN App Server, as downloaded from java.sun site).
JNDI tree contains the following entries:
UserTransaction
test.Dummy
jdbc
ejb
test.Server
Neither test.Dummy nor test.Server (the beans I deployed) want to load.
Any help would be appreciated.
Thanks!
Mark

Never mind. For some reason changing initial context creation from:
Properties p=new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,"whatever factory");
p.put(Context.PROVIDER_URL,"whatever url");
InitialContext context=new InitialContext(p);
to:
InitialContext context=new InitialContext();
fixed the problem. Which is strange, since JNDI tree was listing both objects, and they both could be resolved when using the first code snippet. Only the actual object creation was failing.
If anyone knows why this is so, please explain.
Cheers,
Mark

GetAttribute() method of a view object is returning NULL

Hi ,
I am trying to implement PPR in one of my OAF page and I have taken the following approach.
I have declared the follwing transient boolean attribute in the VO() apart from the existing attribute "Meaning" .
1.MfgEnttity
2.MfgAcct
3.MfgSubAcct
4.MfgCc
5.MfgProj
In the page I have used these attributes in the rendered property as "${oa.XXR2RMfgproSegVO.MfgSubAcct}" like this.
Now in the CO I have written the following code.
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean);
am.invokeMethod("initializeXXR2RMfgproSegVO");
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
String event = pageContext.getParameter(EVENT_PARAM);
String source = pageContext.getParameter(SOURCE_PARAM);
OAApplicationModule am = (OAApplicationModule)pageContext.getApplicationModule(webBean);
am.invokeMethod("handleSegmentChangeEvent");
And the AM code is as follows:
public void initializeXXR2RMfgproSegVO()
OAViewObject vo = getXXR2RMfgproSegVO();
if(!vo.isPreparedForExecution())
vo.executeQuery();
Row row = vo.createRow();
vo.insertRow(row);
row.setNewRowState(Row.STATUS_INITIALIZED);
public void handleSegmentChangeEvent()
OAViewObject pVO = (OAViewObject)findViewObject("XXR2RMfgproSegVO");
OARow hdrRow = (OARow)pVO.getCurrentRow();
String status = (String)hdrRow.getAttribute("Meaning");
System.out.println("poRow "+ hdrRow.toString());
System.out.println("value of the status is "+ status);
if("Entity".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.TRUE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
} else
if("Account".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.TRUE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
}else
if("Subaccount".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.TRUE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
}else
if("Cost Center".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.TRUE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
} else
if("Project".equals(status))
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.TRUE);
else
hdrRow.setAttribute("MfgEnttity", Boolean.FALSE);
hdrRow.setAttribute("MfgAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgSubAcct", Boolean.FALSE);
hdrRow.setAttribute("MfgCc", Boolean.FALSE);
hdrRow.setAttribute("MfgProj", Boolean.FALSE);
Now when in the page I am changing the value of the attribute "Meaning" it is always getting into the else part i.e. where all the attributes are "False".
The two System.out.Println statements are returning the follwing values.
10/03/22 15:41:08 poRow [email protected]3
10/03/22 15:41:08 value of the status is null
Can you please suggest why this "Status" is returning NULL and how I can get the current row selected in the page?
Thanks
Subhabrata

Hi Pratap,
Thanks a lot for your reply.
Can you please suggest how can I rectify the code.I have tried commenting the AM code as follows
public void initializeXXR2RMfgproSegVO()
OAViewObject vo = getXXR2RMfgproSegVO();
if(!vo.isPreparedForExecution())
vo.executeQuery();
//Row row = vo.createRow();
//vo.insertRow(row);
//row.setNewRowState(Row.STATUS_INITIALIZED);
But in the page when I am selecting any segment its throwing Null pointer Exception.
I am new in OAF and this is an urgent client requirement.Please suggest me Where exactly I need to make change in my code.
Thanks in advance...
Thanks
Subhabrata

EjbFindByPrimaryKey returns null

Hello,
We are writing an BMP in 6.1 SP 2. The ejbLoad perfectly loads the data.
From the Remote using the getPrimaryKey() to get the PrimaryKey. That key
is passed to the findByPrimaryKey(PK) call. But, it returns the following.
I have the db-is-shared to false in weblogic-ejb-jar.xml. It looks like it
is returning null and I don't understand why it is doing like this. Whether
it is because, it is not able to find the object through the
findByPrimaryKey or I am making any mistakes.
I even system.out.println inside the ejbFindByPrimaryKey and the key is not
null, it is having the value. Any help is greatly appreciated.

Sentence fragments.
Missing predicates.
It's a bit hard trying to understand your questions.
In BMP you write the ejbFindByPrimaryKey method. Your job in that method is
to verify that it exists in the DB and throw an ObjectNotFoundException if
not. You return the valid PK (the one passed in) if it does exist. So, what
exactly is returning null?

FindNode returning Null And XML Not Accepting Special Characters

Hi All,
i am trying the get the attribute value in the element "ns4:InfoCFDi" using FindNode method, but the method is returning NULL. I used the same code for other sample as well and was successfull. but for this specific XML file(which is below) I am getting a Null.
i can get till S:Body, but when i try to use FindNode for ":Body/s4:ResponseGeneraCFDi" I get Null value.
And I used "S:Body/*[local-name()=" | "ns4:ResponseGeneraCFDi" | "]";
as mentioned in other post but still no success.
==>I Have one more question relating to special characters. I need to use characters such as - ó in my XML to read as well as write. When I try to read i am getting XML parse error and when writing, i cannot open the file properly.
Your help is much appreciated.
My code is here:
Local XmlDoc &inXMLDoc, &reqxmldoc;
Local XmlNode &RecordNode;
&inXMLDoc = CreateXmlDoc();
&ret = &inXMLDoc.ParseXmlFromURL("D:\Agnel\Mexico Debit Memo\REALRESPONSE.xml");
If &ret Then
&RecordNode = &inXMLDoc.DocumentElement.FindNode("" );
If &RecordNode.IsNull Then
Warning MsgGet(0, 0, "Agnel FindNode not found.");
rem MessageBox(0, "", 0, 0, "FindNode not found");
Else
&qrValue = &RecordNode.GetAttributeValue("asignaFolio ");
Warning MsgGet(0, 0, "asignaFolio." | &qrValue);
End-If;
Else
Warning MsgGet(0, 0, "Error. ParseXmlString");
End-If;

First of all you have to supply a value you want to search for and this has to be the complete path to the value. You're saying you already tried that, but can you paste the code which you used for that? I don't see the path mentioned in the code you posted.
*FindNode*
Syntax
FindNode(Path)
Description
Use the FindNode method to return a reference to an XmlNode.
The path is specified as the list of tag names, to the node that you want to find, each separated by a slash (/).
Parameters
Path
Specify the tag names up to and including the name of the node that you want returned, starting with a slash and each separated by a slash (/). This is known as the XPath query language.>
Another option would be this snippet of code:
&InfoCFDiArray = GetElementsByTagName("ns4:InfoCFDi");
&InfoCFDiNode = &InfoCFDiArray [1];
&attValue = &InfoCFDiNode.GetAttributeValue("noCertificadoSAT")
Warning(&attValue);
It creates an array of XML Nodes which match the name "ns4:InfoCFDi". Since there's only one in the XML it's safe to assume it will be the one and only node in the array. I've assigned that node to the variable &InfoCFDiNode and use that to retrieve the attribute "noCertificadoSAT" value. The warning message should display the value supplied there.
Concering the special characters; you will have to change the encoding of the XML. Peoplecode sets this to UTF-8 by default, but doesn't include this in the header. There's a little hack for that somewhere on the web, I'll see if I can find it.

Request.getCookies() returns null, not 0 length array

(reposted from J2EE forum)
Just upgraded to 9ias with Embedded OC4J and we were getting a NullPointerException.
Our previous calls to request.getCookies() AKA http://java.sun.com/products/servlet/2.1/api/javax.servlet.http.HttpServletRequest.html#getCookies()
would return an an array of Cookie Objects or an array of zero length if there are no cookies.
When we upgraded to 9ias, we got the NPE.
Know why?
OC4J implementation of HttpServletRequest doesn't return a zero length array, it returns a null object when there are no cookies!!!
So we had to change our code to catch this.
Not a big problem, and it's fixed now, but it was a problem nonetheless.
Any reason/rationale for why this was done this way? Anyone? Bueller?

Josh,
According to Servlet Spec 2.3 (page 193) SRV 15.1.3.2 Methods for (HttpServletRequest SRV.15.1.3) getCookies() returns null if no cookies present. So we are compliant to the spec.
regards
Debu Panda
Oracle That's strange that the NPE problem didn't occurr until deleting cookies on OC4J, then.
Thanks for responding!

Get textFrame by label returns null and anchored objects

I have the following two functions:
function getByLabel(page, label)
    for(var i=0; i < page.allPageItems.length; i++)
        if( page.allPageItems[i].label == label )
            return page.allPageItems[i];
and
Object.prototype.findItems = function(/*obj*/props)
    if( !('everyItem' in this) )
        throw new Error("Error: " + this + " is not a collection.");
    var ret = this.everyItem().getElements(),
        i = ret.length,
        e, p;
    while( i-- && e=ret[i] )
        for( p in props )
            if( (p in e) && e[p]===props[p] ) continue;
            ret.splice(i,1);
    return ret;
In my page structure, I got one main text frame (the content area) and two vertical text fromes on the sides of the page. There is also a small box textframe on top of the page. All these textboxes EXCEPT the main text frame are ALL "ANCHORED objects". I had to make them anchored objects, eitherwise after importing data, the boxes would jump around. (Example, the small box textframe that is on the top would get moved to the content area textframe etc). Not sure if using anchored objects is the proper way to fix this.
When I try to get the small box text frame, it does not work using the findItems (returns null) but it works fine with the getByLabel method. Why is that?
The calling syntax is:
for( i=0 ; i < doc.pages.length ; ++i )
        var page = doc.pages.item(i);
        var textFrame = getByLabel(page, 'lblSection' ); //This works
        //   var textFrame = page.textFrames.findItems({ label: 'lblSection' })[0]; This does not work, returns null
        if( textFrame != null )
            textFrame.parentStory.contents = "";

(function () {
    // Per the InDesign Scripting Guide, app.activeScript is only
    // valid when a script is directly executed from InDesign, not
    // from the ESTK, so a try/catch block is recommended to handle
    // it.
    var d;
    try {
        d = app.activeScript.parent.parent.fsName;
    } catch (e) {
        d = Folder.appPackage.parent.fsName+"/Scripts";
        return d;

GetImplementation*() methods return null...
