Getfilteredrows("selectFlag","Y") returns null (Urgent)

Hi,
I have created an advanced table on a view object. I created a transient attribute called selectflag with updatable as true. I have one of the column on the above table as link which will show basically details of each row.
In order to populate the details page, I have to pass row number which is one of the column. So I am using getfilieteredrows("selectflag","Y") to retrieve the current selected row.
but the voimpl.getfilieteredrows("selectflag","Y") is returning null.
Should I need to do any more settings on transient attribute.
Your help on this is higly appreciated.

When you click on the image it's a redirect and not a post so it will not enter processFormRequest. processRequest will be entered during the initial rendering cycle of the page so at that time nothing was selected because your page didnot render yet.
As I mentioned in my earlier mail you need to append the additional parameter of the primary key to identify the row. Where are you deleting the record, in the subsequent page or trying to do this in this page's processFormRequest ?
You donot need a radio button at all if you want to use the image. You can also make a form submit by setting fireAction property and set the parameter in the propert inspector instead of appending the primary key.

UrlGenerator.getSpecializedUrlGenerator returning null --URGENT

Hi all,
I am using IUrlGeneratorService in my application as shown below
IUrlGeneratorService urlGenService =(IUrlGeneratorService) PortalRuntime
                    .getRuntimeResources()
                    .getService(
          IUrlGeneratorService.KEY);
          ISpecializedUrlGenerator specUrlGen = urlGenService.getSpecializedUrlGenerator(IPortalUrlGenerator.KEY);
This part of code was working fine but suddenly urlGenService.getSpecializedUrlGenerator(IPortalUrlGenerator.KEY) is returning null..
I have included urlgenerator in the sharing reference of my portalapp xml.. do i need to anything apart from that.
Anyone pls help me to resolve this problem since i need to solve this immediately
Thanks and Regards,
Siva

Hi Siva,
> This part of code was working fine but suddenly
This means the whole code once worked and now, without changing this (part of) code, it returns null? If yes, has the system been patched? On what PatchLevel are you on?

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);

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.

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).

rd.forward(request, response);
return;
//create DVDItem instance
DVDItem dvd = new DVDItem(title,year,genre);
request.setAttribute("dvdItem",dvd);
RequestDispatcher rd = request.getRequestDispatcher("success.view");
rd.forward(request, response);
catch(Exception e){
errorMsgs.add(e.getMessage());
request.setAttribute("errors",errorMsgs);
RequestDispatcher rd = request.getRequestDispatcher("error.view");
rd.forward(request, response);
e.printStackTrace();
System.out.println("exception:"+e);
why does getParameter always return null??? whats wrong?

I don't know. However, I suspect that because you have a tag with the same name as 'title', its causing a name conflict. Chnage the name to something else. If it works, then that's the likely explaination.

Hmm....
some of that looks very familiar to me :-)

1. post your code wrapped in code tags and it'll display it nicely.
2. post to the Java Media Framework topic,
I haven't tried JMF within an applet.
Have you tried getting it working in an application first ?
That should simplify your debugging to start with.
I suspect the Player hasn't started yet, or isn't in a realised state.

What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

Hi Martin,
before this problem started to, I have changed the MappingFactory from
"db" to "file" and then back. I also deleted the jdo_mapping table
inbetween and reconsturcted it with the mapping tool. From then on, it
would not find the object anymore. The object that I wanted to get at is
in the database and an empty object is constructed, which I knew from
putting a breakpoint in the constructor.
Because I am not in production yet, I could just delete the database and
start from scratch. Which cured the problem, but as soon as we will be
online, that is not an option anymore, I guess.
Let me know, if you need more help to reproduce this problem.
Best regards
Wolfgang

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

Any help is appreciated,
Ceilo Huang.

Can you see if the iterator is returning anything in your bean? You
should also try setting the SQL logging channel to TRACE (see the
Logging section of our docs) to see if the SQL generated is valid.

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?

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.
