Extract DDL - types null pointer
version 1.1.2.25.79 - tried to extract DDL types - just generated an empty file
upgraded to 1.2.0.2998 - SqlDeveloper in loop (showing error message box) - forced to kill it. Also, am able click on each object type and will show the create statement. Really need to do all (to many to do one by one). Is this a known issue with the current release?
OK, thanks for the detail. I am unable to replicate your error. (My types export OK)
As you say, you can see the DDL, using the Code tab for the individual type selected in the Connection Navigator, so an alternative, is to select all types in the Types node and right -click for the context menu and select Export DDL.( you can export to file or the worksheet)
Your Export DDL dialog issue is something else. Can you post more detail about your exception here and let's look into it.

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

Here is my simplified example. I hope it helps you.
I am using JDK 1.5.0_06, Oracle 9.2.0.1 database and latest Oracle JDBC driver ("ojdbc14.jar").
create or replace type OBJ as object (
QUANTITY number
,PRICE number
create or replace type VA_OBJ as varray(100) of OBJ
create table TBL (
CLMN VA_OBJ
insert into TBL (CLMN)

rs = s.executeQuery("select CLMN from TBL");
if (rs.next()) {
ARRAY ar = (ARRAY) rs.getObject(1);
Object[] obj = (Object[]) ar.getArray(1L, 1);
if (obj != null) {
STRUCT struct = (STRUCT) obj[0];
obj = struct.getAttributes();
System.out.println(Arrays.asList(obj));
catch (Exception x) {

finally {

how to get the Benefits Rate multiplier value in HCM extract ? used Extract rule type Fastfomula, but returns null.
Formula:
DEFAULT FOR BEN_ABR_NAME IS 'NA'
DEFAULT FOR l_rate_multiplier IS 'X'
L_BG_ID = GET_CONTEXT(BUSINESS_GROUP_ID, 1)
L_EFF_DATE = GET_CONTEXT(EFFECTIVE_DATE, to_date('1951/01/01 00:00:00'))
L_ABRT_ID = GET_CONTEXT(ACTY_BASE_RT_ID, 9999)
CHANGE_CONTEXTS(EFFECTIVE_DATE = L_EFF_DATE, BUSINESS_GROUP_ID = L_BG_ID, ACTY_BASE_RT_ID = L_ABRT_ID )
l_rate_multiplier = BEN_ABR_NAME
RETURN l_rate_multiplierI used DBI - BEN_ABR_NAME.
What is back end query ? can we use query to extract the value in Extracts ? -
Null pointer error if not started with 1st in string
hi, this little pratice is about building a simple shopping cart. the TOAD.JSP will display the item list and quantity, user could check item and input the quantity that they want. if the user input larger quantity than database, servlet will sent the back to TOAD.jsp and show message. now it works if selected from 1 item, but if selected 2nd or 3rd, it will have null pointer error over here:
for(int i=0; i<ItemList.size(); i++)
newit = (ItemBean)ItemList.get(i);
if (item != null && item.equals(newit.getItem()) )
%>
<tr>
<td ><input type="checkbox" name = "item" value="<%= newit.getItem() %>"><b><%= newit.getItem() %> </b><br></td>
<td><input type=text name="<%= newit.getItem() %>Qty" value="<%= orderQty%>"></td>
</tr>
<tr><td colspan = 2>
<font size="3" color="red">
The item <%= newit.getItem() %> is NOT available in stock</font>
</td>
</tr>
<%
} else {
%>
<tr>
<td ><input type="checkbox" name = "item" value="<%= newit.getItem() %>"><b><%= newit.getItem() %> </b><br></td>
<td><b><input type=text name="<%= newit.getItem() %>Qty" value="<%= newit.getQty()%>"></b> </td>
</tr>

thanks for your time!You have prvided unsufficent information and poorly formatted code and as such no meaningful answer can given you at present.
But here is the best that one can guess at.
You have a null somewhere.
Is it coming from this code? I am going to say no.
Where does it come from? I don't know.
Where should you look? In the code that does processing to see what happens when yuo have more than one item.
What should you do next? Start putting in some debugging and tracing statements to see where you are heading off into the null abyss. -

Is there a reason why this is and how do I get by it.
ii. Can I just add the field directly within the MDS>file/user.xml? Would there be an issue with changing an existing attribute metadata using the user.xml?Pradeep thank you for your response. it was helpful. However, I also found the responses to both my questions.
i. The null pointer exception was due to using a complex query I was using in the LOV query. I tried a simple query and that worked fine.
ii. For modifying the user defined attributes one can consult the following forum post:
OIM 11g - Change UDF Field Type form String to LOV

PLease Help me !!
I need this urgently.can you explain what your program tries to do... and
at where it went wrong..Sir,
We are trying to make an project where we can make a person register in our data base & after which he/she can search for other user.
The logged in user can modify his/her own data but can view other ppl's data.
We are in a phase of registering the user & that's where we are stuck. The problem is that after the login screen when we hit register (OK- button) the data are not getting entered in the data base.
Can u please help me??
I am using "jdk1.3' - studnet's edition.
I am waiting for your reply.
Thanks in advance & yr interest. -
Hi there.
I have been working on a test system which will potentially have TestStand at its core, and downloaded/installed the 4.2.1 evaluation. Current details from the information dialog are:
TestStand Engine version 4.2.1 (4.2.1.83)
Sequence Editor Verison 4.2.1.83
The system will drive mobile radio devices using RS232 serial interfaces, usnig a variety of serial protocols (Hayes, and a couple of proprietary binary protocols for other work).
We already have in existence a soak tester, written in VS2005 with MFC unmanaged DLLs and also managed DLLs, which are mixed up together to provide different aspects of the functionality required for the binary protocols.
I have created:
1. a "master wrapper" DLL for the constellation of other DLLs - this offers up a simple C-API interface which I hope TestStand will use. It's called "SerialSessionMgr.dll""
2. a mixed managed / unmanaged "IJW" (it just works) DLL which wraps up the binary logging protocol control interfaces, which are entirely in managed C++/CLI: the "master wrapper" DLL calls into this through an unmanaged interface to create instances of the CLI-compiled class which interfaces to the underlying managed DLLs imlpementing the logging protocol. This is called "WinTseInterface.dll".
Before I started evaluating TestStand, I knocked up a test harness using CPPUnit / MFC, with which I was able to test SerialSessionMgr.dll and its' use of WinTseInterface.dll and verify they worked. The harness loads the DLL dynamically at run-time using AfxLoadLibrary() to try to emulate the way TestStand uses it.
When we open a
TSE session:
The SerialSessionManager makes a call to the
WinTseInterface.dll to "create" a logging instance. The instance is
created in a std::map which is held by the CWinApp derived class, this map
contains boost::shared_ptr of the class which works with a managed class. So we
have a call trace: Client
app->SerialSessionManager{TseStartSession()}->WinTseInterface{WINTSE_GetWinTseBridge()} - WINTSE_GetWinTseBridge()
just creates a new instance of the unmanaged class which interfaces through to
the managed CLI/C++ class beneath, and returns the address to the
SerialSessionManager, which stores it.
The SerialSessioManager actually initialises the WinTseBridge using a method of a C++ pure virtual interface class to the class in the std::map in the WinTseInterface DLL
implements. The initialise call passes miscellaneous details and actually calls
"gcnew" to create the managed class which interfaces to the
underlying managed DLLs which implement the logging protocol.
My logs of the DLL loading as seen in VS2005 debug output are attached this message as PDFs
While trying to fix this, I have tried:
Enhancing the WinTseInterface DLL so it manually loads all the other assemblies in the logging system, including the managed portion of WinTseInterface itself (no effect)
All the different options for the way the C DLL adapter loads and unloads the DLL in the DLL adapter steptype in TestStand
I've even tried calling directly into the WinTseInterface DLL before trying any SerialSessionManager DLL calls to try to load the WinTseInterface DLL completely beforehand
and I cannot stop this exception.
It seems like the object is created in the WinTseInterface DLL OK (I have debugged the creation step which runs for WINTSE_GetWinTseBridge() and the object is created OK) when the SerialSessionManager makes the call, but when it calls the first managed function, which creates the managed object, the DLL is reloaded as managed - I suspect this causes the object to be destroyed or overwritten, and thus the call to initialise bombs with null pointer violation.
Have I done something obviously wrong, and what other approaches can I take?
Does TestStand 4.2.1 have issues with driving DLLs which use managed/unmanaged DLLs beneath them?
My nuclear option is to throw the WinTseInterface DLL out completely and wrap up the managed C++ CLI code in a new interface, entirely managed, and use the TestStand ".Net" adaptor to drive that, creating my step library to run to that directly. This isn't ideal as I have some co-ordination of the protocols which is implemented in the SerialSessionMgr DLL.
I hope someone can help. This one's low level, dirty and a stumper to me.
Many thanks to the NI community. This is my first posting!
Solved!

CPPUnit Test Harness DLL load debug output.pdf 18 KB
TestStand DLL load & crash debug output.pdf 43 KBHi there Ray.
First - many thanks for engaging with this thorny problem. Love the avatar BTW.
I've been using the C/C++ DLL adapter: the original premise of the Serial Session Manager DLL was to provide a simple C type functional interface, using simple data types, so that TestStand would be able to drive the underlying functionality easily through a single DLL.
Seeing as you've been kind enough to respond, I should explain the makeup of the DLLs a little more, I think.
The SerialSessionManager (SSMgr) DLL uses C++ and MFC internally. This is the DLL which TestStand calls into directly through the C/C++ adapter. This DLL does have one odd feature though - because the it uses the Windows Multimedia Timer (implemented in WinMM.dll) I had to artificially create a scenario where it would load the .Net mscoree DLL _before_ it loads WinMM.dll - (http://connect.microsoft.com/VisualStudio/feedback/details/329819/freelibrary-in-the-winmm-dlls-modu...), basically WinMM.dll's init code gets rather upset when .Net DLLs load, which causes the entire executable to be unloaded with subsequent crashes.
To work around this crash, the SSMgr has a single, completely empty, file which is compiled for CLR, effectively forcing a dependency into the DLL on the .Net subsystems and turning the DLL into a "IJW" binary. The resulting DLL doesn't actually have any executable managed .Net assemblies, but I'm guessing that it does contain enough .Net related stubs and information that when the DLL is loaded, mscoree.dll loads before WinMM.dll - and this means the system doesn't crash.
Now, on to the WinTseInterface DLL. My initial description of this little software system was done in something of a hurry.
This DLL is the C++/CLI "IJW" DLL which actually contains managed and unmanaged code. Underneath the WinTseInterface DLL is another system of (this time exclusively C++/CLI) DLL assemblies which implement the TSE protocol interpretation system.
When the SSMgr DLL needs to start a TSE protocol session, it calls a C-API function in the WinTseInterface which creates a new CWinTseBridge class. Here's the steps in a little more detail:
SSMgr DLL calls WINTSE_GetWinTseBridge(), passing in the name of the device which needs it (this is used to put the new WinTseBridge into a std::map in the WinTseInterface DLL) - this call runs just fine, and returns the address of the CWinTseBridge C++ object. This is stored in the SSMgr, because the CWinTseBridge class implements a pure virtual interface which is used by the SSMgr as a way of accessing the CWinTseBridge methods.
We now use the address from (1) to make a call to CWinTseBridge::Initialise(), passing some basic configuration details.
I've run VS2005 debug on the Sequence Editor when running the test, and done F11 step-throughs of the code loading each parameter in the Initialise() call onto the stack, and what appears to happen is that when the call is made, the whole lot steps off into oblivion (a reference to 0x00000000 is made, I think).
Do you think it's worth trying to get this approach to work? It would be useful to retain the control surface in the top of the SSMgr as there is co-ordination of the protocols within the logic of that component. If I move the Wintse control out into a separate managed DLL I may not have that co-ordination (this might be overcome with some design, as I've confirmed that it is possible to "reach into" the WinTseInterface DLL with TestStand and create and use managed objects from assemblies contained within).
Are there any known issues with this version of TestStand using C/C++ CLI IJW DLLs? I haven't found much out there on the web.

Crystal report (crystalReportsViewer) crash with null pointer exception
Hi,
My application are simple : m_crystalReportsViewer.ViewerCore.ReportSource = report; but in throw exception null pointer when I call showDialog.
I see in code, we have method ShowTabHeader.
private void ShowTabHeader(bool isShow)
Grid child = VisualTreeHelper.GetChild(this.tabViews, 0) as Grid;
TabPanel panel = child.FindName("HeaderPanel") as TabPanel;
if (!isShow)
panel.Visibility = Visibility.Collapsed;
else
panel.Visibility = Visibility.Visible;
My problem : child.FindName("HeaderPanel") as TabPanel return null
=> if (!isShow)
panel.Visibility = Visibility.Collapsed;
else
panel.Visibility = Visibility.Visible;
throws null pointer exception.
Do you have any idea about this?
Thanks.

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]

Can't Find Null Pointer Exception
Hey, guys! I've spent a couple of hours trying to figure this out, and I've been unable. When I run my program, I get a long list of errors that basically says I have a NullPointerException at Line 160 in LevelRenderer. I can't figure out what is null after tons of analyzing and experimenting, so I was wondering if one of you could assist me with this.
First, here is the runtime error code:

Here's the class that is giving me the error:

}So one of those three lines is line 160, and whichever line it is, is dereferencing a null pointer. So one of 'myLevel', 'myPlayer', or 'g' is null. Probably not 'g' as you received it as a parameter from Swing. Pretty much cuts it down.
There's nothing here you couldn't have worked out for yourself. The line number was all you needed. -
I can't figure out why I'm getting a Null Pointer Exception
I'm writing a program that calls Bingo numbers. I got that part of the program to work but when I started adding Swing I kept getting a Null Pointer Exception and I don't know how to fix it. The Exception happens on line 15 of class Panel (g = image.getGraphics();). Here is the code for my classes. I'm still not finished with the program and I can't finish it until I know that this issue is resolved.

Not sure, but it may be that you need to call init() after this.setVisible(true). -
Null pointer exception in ISimpleTypeModifiable
Hi
I am trying to add values to dropdownbykey dynamically using this code:
IWDAttributeInfo attributeInfo = wdContext.getNodeInfo().getAttribute("PROCESS");
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
processType.setFieldLabel("PROCESS");
IModifiableSimpleValueSet valueSet = processType.getSVServices().getModifiableSimpleValueSet();
Code is giving null pointer exception in the following line:
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
How to Solve it.Its urgent.
Points will be awarded.Actually the process is the attribute of node within context.
so i changed the code to:
IWDAttributeInfo attributeInfo = wdContext.nodeAuditNode().getNodeInfo().getAttribute("PROCESS") ;
ISimpleTypeModifiable processType = attributeInfo.getModifiableSimpleType();
processType.setFieldLabel("PROCESS");
IModifiableSimpleValueSet valueSet = processType.getSVServices().getModifiableSimpleValueSet();
The second point is: we can't modify the data type of mapped attribute in view controller.
So for that, we have to write that code in component controller. -

Null Pointer exception in Webshop
Hi,
We are facing a problem of null pointer exception in the webshop when opening the product details (only in case of handful of products and not for other products) from the hyperlink of the product in the basket.
The product itself appears with short description as soon as we type the product ID in the basket along with price. Still, only for certain products, we always get the null pointer exception when opening the hyperlink of the product details.
The logs of initial replication as well as delta replications later on do not indicate any errors during replication.
These few products are no different from the rest that are OK in the webshop. The details in the product master is also no different. I have tried delta replication multiple times and all of them have been successful. The trace at Unix level also did not help much.
Can somebody help?

Null pointer exception in toString!
Hi all,
i am getting null pointer exception in toString method.Might be due to threads.Can i synchronize toString?
The code snippent is as follows :
@Override
public String toString ()
if (mSourceInfo != null)
return "Source [Name=" + mSourceInfo.name + ", Description=" + mSourceInfo.description + ", Type=" + mSourceInfo.type + ", Path="
+ ", Online=" + mSourceInfo.online + ", Acknowledged=" + mSourceInfo.acknowledged + ", Tags=" + mSourceInfo.tags
+ ", Dimension:width=" + mSourceInfo.width + ", height=" + mSourceInfo.height + "SourceId=" + mSourceInfo.sourceId;
else
return "Source [Id=" + mObjectId + "]";
}Sourav-Sipani wrote:
Make the following change:No! Don't! Sorry to say that, but this suggestion is bullshit.
1. there is no String constructor that takes any object.
2. sourceInfo definitely is not a String!
3. there is almost never a reason to use the String constructor that takes only a String (if you where trying to do that).
The correct solution would look something like this:
public String toString ()
// Get a local copy of this object so that the
// entire method is isolated from any changes
// in the global object
TypeOfSourceInfo tempSource = mSourceInfo;
if (tempSource != null)
return "Source [Name=" + tempSource.name + ", Description=" + tempSource.description + ", Type=" + tempSource.type + ", Path="
+ ", Online=" + tempSource.online + ", Acknowledged=" + tempSource.acknowledged + ", Tags=" + tempSource.tags
+ ", Dimension:width=" + tempSource.width + ", height=" + tempSource.height + "SourceId=" + tempSource.sourceId;
else
return "Source [Id=" + mObjectId + "]";
}Btw, it seems that the type of mSourceInfo should have a toString, which you could simply call here. Your code seems to do stuff that that Class should be doing instead.
