Null Pointer when fetching VARRAY / OBJECT TYPE
Hi,
i'm trying to fetch a VARRAY, containing an Obeject Type consisiting of two NUMBERS (see scripts below). Now i used JDeveloper to generate corresponding Java Klasses. What i'm trying to do is this:
String SQL = "select quantityprice from ts_transaction_q_history where hist_id = 125608";
Map map = null;
Class obj = null;
Connection tmpCon = null;
PreparedStatement tmpStmt = null;
ResultSet tmpRS = null;
VaQuantitypriceQ100 tmpQP100 = null;
OtQuantityprice tmpQP = null;
OtQuantityprice[] tmpQPArr = null;
ARRAY tmpQP100ARR = null;
try {
tmpCon = getConnection();
map= tmpCon.getTypeMap();
obj = Class.forName("ch.egl.emis.persistence.wrapper.VaQuantitypriceQ100");
map.put(VaQuantitypriceQ100._SQL_NAME, obj);
tmpCon.setTypeMap(map);
tmpStmt = tmpCon.prepareStatement(SQL);
tmpRS = tmpStmt.executeQuery();
while (tmpRS.next()) {
tmpQP100ARR = (ARRAY) tmpRS.getObject(1);
System.out.println(tmpQP100ARR.toString());
ORADataFactory factory = VaQuantitypriceQ100.getORADataFactory();
tmpQP100 = (VaQuantitypriceQ100) factory.create(tmpQP100ARR, OracleTypes.ARRAY);
Long quan = tmpQP.getQuantity().longValue();
Long price = tmpQP.getPrice().longValue();
Well, everything works fine, as far as i can see. I get a Quantity (quan), but when i try to get the price, i get a null pointer.
I am sure, that there is data on the DB and the value for price is nut null. i an using JBoss 3.2.7 and Oracle 9i. Connection is "thin" (may that be the Ptoblem)?
Anybody there who had similar problems or has a solution for this?
Many thanks
Sven

Using Pl/SQL Developer
Hi I'm new to collections, object types etc, so I aologize for any poor wording and missed concepts...
I need to output a ref cursor from my package (for a summary report in SQL Server Reporting Services 2005). The summary report has two fields that come from the database table and 5 calculated fields. My idea for creating the ref cursor is as follows:
1. Define an object type at the schema level
2. Define a table (collection) type at the schema level
3. Define a ref cursor at the package level
4. Using dynamic SQL create a sql statement creating virtual columns for the 5 calculated fields
5. Fetch cursor with dynamic sql into object type one record at a time
6. Calculate the other five field values and update the object for each record processed
7. Add the object 'record' to the table (collection) after each record is processed
8. After the fetch is complete, convert the table to a ref cursor for returning to my application
Here is what I have so far. I have cut out several of the calculated fields for simplicities sake. It is not complete and I don't know how to fetch the database row into the object, nor convert the collection to a ref cursor.
Any help would be greatly appreciated.

open curout for SELECT *

Null Pointer when hiding view attribute
Hi,
Attached is my override of doDML of table media. The view object contains fields from tables media and idn. The primary key to both, and the link field is called udid. I try to hide the media.udid but I get a null pointer error.
Do these line (also below) need the primary key of the media table (the table whose doDML the code is located)?
EntityDefImpl home = IdnImpl.getDefinitionObject();
IdnImpl idn = (IdnImpl)home.findByPrimaryKey(getDBTransaction(),getPrimaryKey());
The point of the above code is to grab another field I need for a procedure(from table IDN). When I comment these lines out the error goes away. Procedure doesn't work, but it runs. It seems weird I know to go to another table to capture udid as you can see below, even though it's available to this table instance. The reason I did that (and chose to hide media.udid) is to have a primary key available to table IDN, so as to grab the other field I need (min_val).
ANy thoughts? I haven't hid a view attribute before..
Thanks.

Null pointer when trying to initialise speech recognition
Hi all,
I am attempting to utilise the JSAPI for a project for display at my Uni that utilises freeTTS and also some Java speech recognition. Through the tutorials online (such as the Hello World) I have built my speech recognizer but as I try to allocate() for the speech recogniser the program gives me a null pointer.
The grammar file that I load into the file reader exists and I do not get a file not found exception. Can anyone see a blindingly obvious error that I am missing?
Code below. The rec.allocate() (third line after the try... is where i am getting my null pointer from.
Cheers
Mark
public BigEars(SpeakEasy gui){
mainGui = gui;

RuleGrammar rules = rec.loadJSGF(reader);
rules.setEnabled(true);
rec.addResultListener(this);
rec.commitChanges();
rec.requestFocus();
rec.resume();
catch (Exception e) {
message("There is a problem with this code.");
e.printStackTrace();
Hi dheeraj_chd,
I never got a reply to this so to move forward I actually incorporated the Sphinx4 speech recognition program into my project. I do not know if this is any help to you but I got it up and running OK with it.
http://cmusphinx.sourceforge.net/sphinx4/
I hope this helps. It does dramatically increase the size of the application you are writing but at least it works!

I have a problem with VARRAYS.
With the following script there is an error when creating the VArray ->

I can't explain why.
Could it be that with the Type Typ_STUDENT the attribute COURSE already is a

Is there a switch for 'FORCE' when creating object type?
Where is the property to indicate whether or not to include the keyword FORCE when creating an object type?
Thanks, the support that SDDM provides for Object Types is much better than Oracle Designer. I am looking forward to the release where we can flag a method's parameter as 'DEFAULT NULL' and especially the ability to include an inherited or included attribute as part of the primary key or the primary key. With the last release where the method body is stubbed out with 'BEGIN NULL; END;' really provided the basic ability for rapid prototyping. Once the key 'FORCE' is in place, the ability to rapid prototype will become even more functional.

Note correction Instructions point towards object type FUGR / REPS
Folks
While looking at Correction Instructions for a note, its pointing to changes in Object Type FUGR, REPS
I am familiar with Object Type Class and methods and how to navigate to them but am unfamiliar on how to check the Object Type FUGR, REPS and the corrections made to them.
Is there any standard T-code or process to check the Object Type FUGR, REPS ?
ThanksFurther to above ;
SAP systems record all changes made in the system in transport requests. There are different types of transport objects, depending on the type of change. Each transport object consists of three pieces of information:
· Program ID
· Object type
· Object name
Program ID can be R3TR, LIMU, or LANG. R3TR is a group of objects, and LIMU is a subobject of a larger object. This means, for example, that R3TR PROG RSPFPAR is the transport of the program RSPFPAR with all its information (source code, text elements, properties, ...), while LIMU REPT RSPFPAR describes the text elements of this program.
The complete object R3TR PROG includes the following subobjects, among others:
LIMU REPS
LIMU REPT
LIMU DYNP.
Also REPS stands for Report Source Code

Edited by: duyhai707 on Jul 13, 2011 8:09 PMA lot I don't understand in here... actually, I don't understand anything in your post:
When you call ShowDialog, what exactly are you trying to show? The code is the decompiled showtabheader method of the viewer. So, are you trying to override the viewer control and reportalbum? My guess is that the null reference is for the reportalbum's child object which is not the reportalbum object of the viewer. I don't understand why the code since its all handled internally to the viewer anyhow.
Perhaps searching the forum for code sample will help?
Also, see the [WPF Demo|http://www.sdn.sap.com/irj/scn/elearn?rid=/library/uuid/a09f7025-0629-2d10-d7ae-df006a51d1a8]

Null Pointer Exception Error's in WebDynpro Java
Hi All,
How Types are coming Null Pointer Exception Error's in WebDynpro Java, Please provide the types.of Errors.
Ex. Cardinality Type not correct etc...
Thanks,
Bye,
Vijay Hari.HI
Null Pointer Exception can occur in may instances , for suppose
1) when you create a Value Node with some attribute which has cardinality , and you have not
initialized the Node , then it would through Null Pointer exception ,
2) when you integrate the RFC and parameters you pass as input to the RFC are not set correctly
then there could be null pointer when you execute the RFC
3>or may be when you doesnot bind the node when using webservice then there could be null pointer exception
and there could be many occurances for the exception -
Object Types Attributes (Data Modeler 3.0 EA1.)
Hi,
Will the attribute object type support in data modeler be upgraded to the same functionality as column relational table support in 3.0? For relational columns I can attach a domain to a column, I can't attach a domain to an attribute in an object type. Also for a column I can define a 'Units', that is VARCHAR2 (30 BYTE) orVARCHAR2 (30 CHAR). If can't do this with the (Data Modeler 3.0 EA1.) for an object type's attribute. Will this be included?
Thanks,
ScottSue,
Thanks to you and your team for extending this to the object type (structured type) portion of SDDM 3.3 EA1 and 3.3 EA2. The object type portion of SDDM is pretty robust now for modeling and actually generating useable structures in the database (Oracle) now. With 3.3 EA2 at this point it will be much easier to take advantage of the object type features in the database and our applications. I have been waiting since Oracle version 8 for the tools team to provide a modeling tool that mirrors the functionality the server team has provided when it comes object types.
Thanks for this in SDDM 3.3 EA1 and SDDM 3.3 EA2!

Problem in fetching varray of Object type
Below are the code,
where am calling an procedure which returns me Varray of object type test_obj(id number, name varchar2);
Am facing an problem in get the object(test_obj) from ARRAY object
the exception is java.lang.ClassCastException: java.lang.Object
at line number No 12..
Can anyone suggest me How handle this...
1. STRUCT test_objStruct ;
2. ARRAY test_arr;
3. OracleCallableStatement cs = (OracleCallableStatement)
4. con.prepareCall("{call test_data(?)}");
5. cs.registerOutParameter(1,oracle.jdbc.driver.OracleTypes.ARRAY,"TEST_ARR");
6. cs.execute();
7. test_arr = (ARRAY)cs.getObject(1);
8.System.out.println("array varible "+test_arr.getBaseTypeName());
9. System.out.println("length "+test_arr.length());
10. Map map = (Map)con.getTypeMap();
11. map.put("TEST_OBJ", Class.forName("oracle.sql.STRUCT"));
12. test_objStruct = (STRUCT)test_arr.getArray(1,1);
13.Object country_attrs[] = test_objStruct.getAttributes();
14.System.out.println ("ID: " country_attrs[0]);
15.System.out.println ("Name: " +country_attrs[1]);
the output is..
array varible TEST_OBJ
length 106
Error java.lang.ClassCastException: java.lang.ObjectHi,
The error occurs on line 12, the first time through the loop, when you try to execute:
vClient(iCounter).ename_obj:=i.ename;
At that point, vClient (1) is not an Employee object; it's NULL.
Try this:
DECLARE
TYPE tvrEmploy IS VARRAY(10) OF Employee;
vClient tvrEmploy;
iCounter integer := 1;
CURSOR client_cursor IS
SELECT ename, sal
, empno -- ADDED
FROM scott.emp
WHERE rownum < 11;
BEGIN
vClient := tvrEmploy (null,null,null,null,null,null,null,null,null,null) ;
FOR i IN client_cursor LOOP
vClient (iCounter) := Employee (i.ename, i.empno, i.sal); -- CHANGED
iCounter := iCounter + 1;
END LOOP;
FOR I IN REVERSE 1..10 LOOP
dbms_output.put_line(to_char(I) ||' '|| vClient(I).ename_obj ||' '|| vClient(I).empno_obj ||' '||
vClient(I).sal_obj);
END LOOP;
END ;
