[Forms10] + Client_Ole2 problems on getting null cell

Hi,
I've a little problem on excel file import to oracle form.
When my excel cell have a value all works fine, but if i try to get a null cell value with "client_ole2.get_char_property" i get the WUO-714 error.
I've used the same function in oracle form 4.5 and i've never got any problem.
Thanks all

Hi,
I have same requirement to get data from Excel cell in form 10g. Can you help me by the way send to me your sample code.
Many thanks for your help!

Trying to get multiple cell values within a geometry

I am provided with 3 tables:
1 - The GeoRaster
2 - The geoRasterData table
3 - A VAT table who's PK is the cell value from the above tables
Currently the user can select a point in our application and by using the getCellValue we get the cell value which is the PK on the 3rd table and this gives us the details to return to the user.
We now want to give the worst scenario within a given geometry or distance. So if I get back all the cell values within a given geometry/distance I can then call my other functions against the 3rd table to get the worst scores.
I had a conversation open for this before where JeffreyXie had some brilliant input, but it got archived while I was waiting on Oracle to resolve a bug (about 7 months)
See:
Trying to get multiple cell values within a geometry
If I am looking to get a list of cell values that interact with my geometry/distance and then loop through them, is there a better way?
BTW, if anybody wants to play with this functionality, it only seems to work in 11.2.0.4.
Below is the code I was using last, I think it is trying to get the cell values but the numbers coming back are not correct, I think I am converting the binary to integer wrong.
Any ideas?

Hey guys,
Zzhang,
That's a good spot and as it happens I spotted that and that is why I am sure I am querying that lob wrong. I always get the a logic going past the total length of the lob.
I think I am ok using 11.2.0.4, if I can get this working it is really important to us, so saying to roll up to 11.2.0.4 for this would be no problem.
The error in 11.2.0.3 was an internal error: [kghstack_underflow_internal_3].
Something that I think I need to find out more about, but am struggling to get more information on is, I am assuming that the lob that is returned is all cell values or at lest an array of 4 byte (32 bit) chunks, although, I don't know this.
Is that a correct assumption or is there more to it?
Have either of you seen any documentation on how to query this lob?
Thanks

Problem with select all cells in JTable

Hi guys! I get some problem about selecting all cells in JTable. I tried to used two methods:
1> table.selectAll()2> changeSelection(firstcell, lastcell,false,true)
firstcell:[0,0], lastcell[rowcount-1,colcount-1]
Result: only the first row selected when i use both methods.
Note: i set up the selection model as following:
this.dataSheet.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
                this.dataSheet.setCellSelectionEnabled(true);
                this.dataSheet.setRowSelectionAllowed(true);
                this.dataSheet.setColumnSelectionAllowed(true);Thanks !

What selection properity should be changed in order to enable selectAll() method work properly? Is there Any constraints? Here is the TableModel I am using. And i set up selection mode use the following code:
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
table.setCellSelectionEnabled(true);
table.setRowSelectionAllowed(true);
table.setColumnSelectionAllowed(true);

Getting null values from nodes using DOMParser

Hi
I'm having problems retrieving the values from an XML doc.
I'm using the DOMParser, but instead of retrieving the values
from the nodes, I just get null.
Code fragment :
DOMParser parser = new DOMParser();
parser.parse(url);
XMLDocument doc = parser.getDocument();
NodeList nl = doc.getElementsByTagName("*");
Node n;
iNode = nl.getLength();
for (int i=0; i<iNode; i++)
n = nl.item(i);
String szNodeName = n.getNodeName();
System.out.print(szNodeName+ " (" );
System.out.print(n.getNodeValue()+")");
System.out.println();
The result is
course (null)
Name (null)
All the node names are correct, but the node values are NOT
displayed.
Any idea ?

null

According to the DOM Level 1 spec, the "value" of an ELEMENT node
is null and the getNodeValue() method will always return null for
an ELEMENT type node. You have to get the TEXT children of an
element and then use the getNodeValue() method in the text nodes.

Problem in getting the database connection from a connection pool

Hai All,
I am facing a problem in getting the database connection from a connection pool created on weblogic server 8.1.
I am using the Oracle database 8.1.7.
I have configured my connection pool, datasource and JNDI in weblogic.
In my java program i have the following code to retrieve the connection.
import java.sql.*;
import java.util.Hashtable;
import javax.naming.Context;
import javax.naming.InitialContext;
class jdbcshp1 {
    public static void main(String[] args) {
     Connection connection = null;
     try {
           Hashtable ht = new Hashtable();
           ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory"); // Wanna get rid of this.
           ht.put(Context.PROVIDER_URL,"t3://localhost:7001"); // wanna get rid of this.
           // Get a context for the JNDI look up
           Context ctx = new InitialContext(ht);
        javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("myjndi1");
          //Create a connection object
          connection = ds.getConnection();
     The above code is working fine but, the two ht.put statements are creating problem.
The problem is, after converting the application into WAR file it can be deployed
on any machine or different port on same machine. My application fails if its deployed on
weglogicserver which is at different port.
Is there any way that i can get rid of those ht.put statements or any other way to solve the problem.
any help is appreciated.
Thanks in advance
Pooja.

Hai All,
Firstly, thanks for ur reply.
Even i have seen some code which uses context constructor with out any parameter and works fine.
i dont understand why its not working for my code.
When i remove those ht.put code and use context constructor with out any parameter, it giving an error.
Context ctx = new InitialContext();
javax.sql.DataSource ds = (javax.sql.DataSource) ctx.lookup ("ocjndi");
connection = ds.getConnection();The error is as follows:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
the above error is forcing me to include those code but if the port number is changed the code will not work. Plz let meknow if some setting have to be made.
I appreciate all ur valuable help.
Thanks once again.
Pooja.

Problem in getting the BASKET HEADER DATA in java class?

Hi Gurus,
In the order_change.jsp i have created a new custom input field and when i give some text in it, i should pass this as extension data. For this i have created a class to add this extension data:
UserSessionData userSessionData = UserSessionData.getUserSessionData(request.getSession());
BusinessObjectManager isaBOM = (BusinessObjectManager)userSessionData.
                                                      getBOM(BusinessObjectManager.ISACORE_BOM);
ZCustomer mybom = (ZCustomer) userSessionData.getBOM(ZCustomer.ZCUSTOM_BOM);
Basket basket = isaBOM.getBasket();
HeaderData headerData = isaBOM.getBasket().getHeaderData();
String extBasketHeaderData = request.getParameter("test");
headerData.addExtensionData("ZTEST", extBasketHeaderData);
But iam getting a null pointer execption when the following is executed in the above code
HeaderData headerData = isaBOM.getBasket().getHeaderData();
Can you please help me why i am getting null pointer exception when i try to get the header data.
I have tried interpreting my action class with the following classes
1. ordersend.do
2. maintainorder.do
2.orderchangeconfirmed.do
but not able to get the header data if include in any of the above the action class.
Please help me out in this regard.
Thanks a lot in Advance.
Regards,
Lakshman.

Hi All,
I have a similar kind of problem. I want to add extension data to a standard FM . But when I am creating a basket object
Basket basket = isaBOM.getBasket();   I am getting an error saying
                                                Type mismatch:Cannot convert from void to basket
and also If I am trying to import
                                                import com.sap.isa.businessobject.order.Basket;
I am getting an error saying
                     This compilation unit indirectly references the missing type com.sap.isa.businessobject.BusinessObjectBase(typically some required class file is referencing a type outside the classpath)
Kindly help me on this.
Thanks

Getting null value while parsing "XML String" with encoding WINDOWS-1252.

Hi,
when I am converting the Follwoing "xml string " to Document, I am getting the "null" as a document value.

                             </item>
                            </category>"
My "xml string" has the encoding vaule: WINDOWS-1252.
I am using the following code to convert the "xml string" to Document. I am getting the Document values as a "null" while converting the above "string xml"
        String strXML = //my above string xml.
        DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
        docBuilderFactory.setIgnoringElementContentWhitespace(true);
        docBuilder = docBuilderFactory.newDocumentBuilder();
        doc = docBuilder.parse(new InputSource(new StringReader(strXML)));
        System.out.println("doc value.."+doc)//I am getting null value for "doc".
Can anyone help me to resolve the issue.

(without the rest of the code, i'm guessing that) most likely you are grabbing the first child node of the item element. however, you are not accounting for some text nodes that are most likely in that list, like the whitespace between the item element and the attribute element. please go read some tutorials on xml, there are thousands of them out there, and they will answer all you initial questions much more efficiently than posting each step to the forums.

Hi Ravi,
First i would suggest you to test/execute the webservice to makesure that its working properly.
If yes, pass all the madatory fields to the webservice input parameters. In your case customerID could be a madatory parameter to get the address.
You can pass that parameter by customer.setCustomerNo().

I've got a problem with getting correct bytes of a newly resized image. The flow is that I retrive an image from the filesystem. Due to the fact that it is large I resize it to a 50x50px thumbnail. I can display this thumbnail in #benchmark1 (see code below). Unfortunately something's wrong with my imageToBytes funtion which returns reasonably small size of image but is totally useless - I can't make an image of it anymore so at #benchmark2 the application either crashes or keeps freezing. I saved this byte array on my disk and tried to preview under Windows how does it look but I got a message "Preview unavailabe". I did some digging in the Internet and I supposed that it's because I don't use any jpg or png encoders to save the file. Actually I think that it's not the case, as the bytes returned from method imageToBytes look weird - I cannot even make a new image of them and display it without any saving in memory.
                              byte[] bytes = FileHandler.readFile (
                                      FileHandler.PHOTOS_PATH, fileName);
                              Image img2 = Image.createImage (bytes, 0, bytes.length);
                              img2 = ImageHandler.getInstance ().resize (img2);
                                                //#benchmark1
                              bytes = ImageUtils.imageToBytes (img2);
                              img2 = Image.createImage (bytes, 0, bytes.length);
                                                //#benchmark2my imageToBytes function is as follows:
     public static byte[] imageToBytes (Image img)
          int[] imgRgbData = new int[img.getWidth () * img.getHeight ()];
          byte[] imageData = null;
          try
               img.getRGB (imgRgbData, 0, img.getWidth (), 0, 0, img.getWidth (),
                       img.getHeight ());
          catch (Exception e)
          ByteArrayOutputStream baos = new ByteArrayOutputStream ();
          DataOutputStream dos = new DataOutputStream (baos);
          try
               for (int i = 0; i < imgRgbData.length; i++)
                    dos.writeInt (imgRgbData);
               imageData = baos.toByteArray ();
               baos.close ();
               dos.close ();
          catch (Exception e)
          return imageData;
I've run totally out of any idea what's wrong, please help!

Hey Crawlie,
Please note that simply writing int values into ByteArrayOutputStream will not suffice. Please have a look at the following conversion from int pixel value into byte[4]:
public static final byte[] intToByteArray(int value) {
        return new byte[] {
                (byte)(value >>> 24),
                (byte)(value >>> 16),
                (byte)(value >>> 8),
                (byte)value
}Good Luck!

Problem in getting sandbox path in Content Database

Hello all,
we have created a custom application using Oracle Content database API, which upload files to content database programmatically. For this we are using following code to retrieve sandbox
try
FdkCredential credential = new SimpleFdkCredential(username,password);
ManagersFactory session = ManagersFactory.login(credential,url);
FileManager fileM = session.getFileManager();
Item sandbox = fileM.resolvePath(sandbox_path, null);
Item workspace = (sandbox == null) ? null :
fileM.resolveRelativePath(sandbox.getId(),workspace_name, null);
catch(FDKException e)
e.printStackTrace();
Here, sandbox_path and workspcae_name are the names of sandbox and workspace in contentDB. credential, session and fileM are creating fine, but unable to get the sandbox Item.
when we are running the same application in local, it executed successfully and all the files uploaded successfully. There we didn't get any problem. But the same files when we ported to server and tried to upload files to content database we are unable in getting Item object that is sandbox. Instead of retrieving sandbox we are getting null value. Both custom files and Content Database are on same server.
Can anyone please help use why this is happening.

Hi Nitin,
I think you can use CODE similar to below.
Check the function module SXMI_XMB_SYSLOG_READ for more details. It contains similar logic.
SUBMIT RSLG0000 LINE-SIZE 255
         WITH TR_TERM EQ '*'
         WITH TR_DATE EQ FROM_DATE
         WITH TR_TIME EQ FROM_TIME
         WITH TR_EDATE EQ TO_DATE
         WITH TR_ETIME EQ TO_TIME
         WITH TR_CPU   EQ SERVER_NAME
       WITH TR_PAGES EQ '003'         " Begrenzung Anzahl Seiten
         WITH TR_USER EQ LOOKING_FOR_USER
         WITH NOCODEVC EQ 'X'
         WITH NOCOTASK EQ 'X'
         WITH NOCOMAND EQ 'X'
         WITH NOCOTRAN EQ 'X'
         WITH NOCOTERM EQ 'X'
         EXPORTING LIST TO MEMORY
         AND RETURN.

       TABLES
            LISTOBJECT = LIST_IN_MEMORY

Getting null returned when working with Linked Lists

Ok, i'm having the same problem with a couple of methods that deal with linked lists, and i was hoping someone could lend me a hand. First off, the specifications for one of the methods:
An iterative procedure smallElements
PARAMETERS: a ListItem reference, ls
an integer n
RETURN VALUE: a new list identical to the given list, except
that it contains no occurrences of numbers greater than n.
for example, given input list ( 3 2 6 3 4 ) and 3,
the return value would be the list ( 3 2 3 )
And here is my code:
ListItem smallElements(ListItem ls, int n){
ListItem small = null;
ListItem result = small;
if(ls == null)
return null;
else{
while(ls!=null){
     if(ls.number <=n){
     result = new ListItem(ls.number, null );
     result = result.next;
     ls = ls.next;
return small;
Like the topic says, i keep getting null returned as a value. I have tried setting small= new ListItem(ls.number, null), and that actually returns the correct list, except that the first number is repeated twice. I would greatly appreciate any assistance.

I am not sure I understand your code. What exactly are those ListItems? It seems to me that you are dealing with single List elements, while the specification says that you are supposed to return a List.
But the main error is that you have two ListItem objects there, which seems to fill the same purpose - only that you use one, and return the other. 'small', which is the one you return, never get set to anything else than null.
I think you should do something like this: make a new, empty list to return
for element in parameterlist
    if number is smaller than n
        add this element to returnlist
return returnlist

Problem about get the workflow context

There are 2 servers.
One is Weblogic server (server1), deployed a fusion web project on it.
Another is BPM server (server2), deployed the bpm process on it.
On the fusion web project, we use API to get the tasks. But we encountered a problem about get the workflow context.
There are 2 method to get the workflow context.
1. getTaskQueryService().authenticate(userId, password, null, null), this method need to pass in useId and password, we can get the user form request but can't get
password.
2. getTaskQueryService().createContext(request), we pass the request on server1, but can't get the context on server2, exception thrown.
Appreciate if you can give some help.

Getting the cell id

i have read many threads about this and i am very confused.. some say that it is possible and some say that it is not possible.. can i get the cell id using j2me? if yes, are there any sourcecodes or examples that you can share? thanks

Problem in alignment of cell content in Advanced Table

Hi,
I have a column which has some flag say 'Y' or 'N'.
I have created an advanced table and followed the dev guide for aligning the value in the center of the cell.But i m getting null pointer exception when I m using getColumnFormats method of advanced table.
OAAdvancedTableBean resultsTableBean =(OAAdvancedTableBean)webBean.findChildRecursive("region2");
System.out.println("index"+pageContext.findChildIndex(resultsTableBean,"column1"));
OAColumnBean manuPartNoCol =(OAColumnBean)webBean.findChildRecursive("column1");
manuPartNoCol.setAttributeValue(ALIGNMENT_GROUP_ATTR,ICON_BUTTON_FORMAT);
resultsTableBean.prepareForRendering(pageContext);
// now get a handle on the array of Column Format Dictionaries
DataObjectList myColumnFormats = resultsTableBean.getColumnFormats();
System.out.println("myColumnFormats.getLength"+myColumnFormats.getLength());
// get a handle on the specific Column Format Dictionary you
// are interested in
oracle.cabo.ui.data.DictionaryData myIconColumnFormat = (oracle.cabo.ui.data.DictionaryData)
myColumnFormats.getItem(pageContext.findChildIndex(resultsTableBean,"column1"));
// set the CELL_NO_WRAP_FORMAT_KEY property to TRUE
myIconColumnFormat.put(COLUMN_DATA_FORMAT_KEY , ICON_BUTTON_FORMAT);
BUt if I use table bean instead of advanced table bean then the same code works.
Basically i have to set the alignment of the cells in the advanced table bean in the runtime.
Can anybody suggest something?
Thanks

Provide the error stack.
