OCCI BUG! Error reading Objects which contain NULLS

The original problem was that I couldn't retrieve a SDO_GEOMERTY object from a table. Using OCCI and the OTT utility I always got assertions and exceptions.
Various people have already reported this problem (e.g. Hu Cao, "HELP!! operating SDO_GEOMETRY with OCCI" ).
After several hours of testing I found the real problem: When ever an object contain NULLS the problem appears.
Eg. the "occiobj"-demo works fine with the original data. However, after setting one value in a publ_address object to NULL
eg. UPDATE publisher_tab SET publisher_id=11, publisher_add=publ_address( NULL , 'NEW YORK') WHERE publisher_id=11;
the demo program crashes!!!
After discovering this, I generated a SDO_GEOMERTY object containing no NULLS and suddenly my program was able to retrieve the object.
Consequently there is only one big problem remaining:
A valid SDO_GEOMERTY object has to have NULLS in it!!!!
Comments please

(I'm working with Win2K and the Oracle 9i Client. The bug appears in conjunction with both Oracle 8.1.7 and Oracle 9i)

I downloaded the Oracle 9i Release 2 (9.2.0.1) Client for Win and there I have less problems to get objects which contain NULLs.
Now if a standard-typed member (of an objects) is NULL, OCCI recognizes this correctly and the program never crashed again.
However, there is one BUG remaining. If an object-typed member is NULL the program still crashes.
Eg. if the SDO_POINT member (type MDSYS.SDO_POINT_TYPE) of an MDSYS.SDO_GEOMETRY object is NULL,
the program crashes in the
void sdo_point::readSQL(oracle::occi::AnyData& streamOCCI_)
function (which was generated by the OTT utility). It seems that in function
void sdo_point::readSQL(void ctxOCCI_)
the streamOCCI_.isNull() command doesn't recognize that the sdo_point object is NULL.
(see source code below)
WITH THIS BUG YOU CANNOT GET A MDSYS.SDO_GEOMETRY OBJECT WITH OCCI!!!
Has anybody solved this problem? Is there a bug fix?
Thanks in Advance
Johannes
void sdo_point::readSQL(void ctxOCCI_)
sdo_point *objOCCI_ = new(ctxOCCI_) sdo_point(ctxOCCI_);
oracle::occi::AnyData streamOCCI_(ctxOCCI_);
try
if (streamOCCI_.isNull()) // <-- doesn't recognize that the object in NULL
objOCCI_->setNull();
else
objOCCI_->readSQL(streamOCCI_); // <-- consequently the actual readSQL is called, which crashes...
catch (oracle::occi::SQLException& excep)
delete objOCCI_;
excep.setErrorCtx(ctxOCCI_);
return (void *)NULL;
return (void *)objOCCI_;
void sdo_point::readSQL(oracle::occi::AnyData& streamOCCI_)
X = streamOCCI_.getNumber();
Y = streamOCCI_.getNumber();
Z = streamOCCI_.getNumber();

Error reading wsdl file excepetion null

Hi
I am trying to invoke a proxy service (web service) wsdl from a bpel process. When i add a web service adapter, put url of external web service and save it, all my service end points defined in the BPEL process are becoming non editable. Binding of operation is changing from web service to HTTP binding for all end points. When I try to edit any partner link, Jdev throws an error " error reading wsdl file excepetion null " for local services. For external service, even though i am refering to a url on the server, it points to " C:\Oracle\Middleware\jdeveloper\jdev\bin\...\xxxx?WSDL" and throws same error " failed to read wsdl file(System could not find the path specified". I am just clueless as to why this is happening. Any help is much appreciated.

Authorization objects which contain company code field

Hi,
We are looking for list of Authorization objects which contain company code field for Audit. The listing should have Role, Authorization obj and the <b>company code and values</b>.
Is there any we can query this info.
Thanks,
Sam

Hi,
You can use the follwing
in USR12 table
in USOBT table (but you get the details for the Auth Obj in the Tcodes and their field values.
But as far as my knowledge goes you will get all the Auth Obj with Company code field
Caution: If there are some objects in not check or are which are not in any tcodes then they will not be captured.
But they are very less I guess and so i think you can capture most of the Auth Obj I guess

Error reading zip file containing an excel file

Hi all,
Using servlets I am able to zip an excel file using java.util.zip package. The excel file is created using POI API.
While I save and extract the zip file on my machine and then open the file in MS Excel. Excel pops a message saying "MS Office Excel has encountered a problem and need to close" and it gives me an option to "Recover my work and restart MS Office Excel". I select the option and then MS Excel does a document recovery and I am able to view my data. I get an excel repair log file saying as follows
"Microsoft Office Excel File Repair Log
Errors were detected in file 'C:\Documents and Settings\JohnDoe\Desktop\excel\test.xls'
The following is a list of repairs:
Damage to the file was so extensive that repairs were not possible. Excel attempted to recover your formulas and values, but some data may have been lost or corrupted.
I have attached my servlet code down below I suspect there is a problem with PrintWriter to output or do I need to use OutputStream to write excel data.

Jdcunha,
I am new to the field but encountered the same problem and recently found a solution. Hope this helps.
For my project I wanted to create individual Excel 2003 workbooks for each file I created. Excel would give me the same error it gave you when I used the same HSSFWorkbook object. I tried creating a new Workbook object each time, but ran into the same issue.
I ended up fixing the error by creating a new instance of my write-to-excel class each time I wanted to create a new workbook, instead of just recreating a new HSSFWorkbook object. It works perfectly and the Excel errors don't show. It may also be important to note I used OutputStream, I did not try it with printwriter.

Error connecting Domains: Invalid parameter,tdom_link contains NULL

probably 6.5.
When booting I get the next error:

Can anyone give any clue?
Thanks in advance, bye!

Do you have an idea in which section I can look for the mistake? I have other domains
running correctly configured in this config file, and everything seems to be ok
for this domain too.
Thanks in advance

I have a lot of grief with this version of Windows Media Player.
It is very buggy and frustrating to use.
I have my Music library on a QNAP NAS, which is as reliable as they come.
System notifications make it not save changes. It also does not do a good job of interpreting albums and artists from folders. Changes to track names are not saved, nor are tracks moved to other albums, renamed albums, changes to genre, artist
or date. It separates and merges albums/tracks without sense or reason. Some changes I've made up to 4 times, then closed WMP and re-started my machine to check if it has/hasn't saved the changes. Often it has not.
This is the first time I've used WMP in this capacity, and I do not recommend it.
New service pack please.

Last time I checked contexts and lookups could return null values. And your code is not checking for a null value return.

Unable to delete Transport Request which contain locked objects

Hi all,
I need to delete some unusable transport requests but as they contain locked objects, it's not possible to delete them. Release operation is just allowed. After releasing these transport requests, I can not find them any more in queue. Please help to find these transport requests which are released and also provide a solution to delete instead of releasing them.
Thanks in advance,
Sanaz.

Hi,
Thank you for the reply.
1. What do you mean by transport request , Shipment Request, Shipment Order or Tour.
A. I mean requests which can be transported between SAP Systems using TMS (Transport Management System).
2. What are the objects which has been locked and due to that you are facing this problem.
A. There are diffrent object types. For examle some customizing have booen done or SAP Note correction has been implemented, ... Therefore some objects have been locked due to these operations
3. Let's say if it's an freight Unit, then Pls confirm that System dump / error is not the cause for this.
A. I have no idea about "Freight Unit".
Thanks,
Sanaz.

//if i pass true as parameter in FileOutputStream it gives Stream Corrupted exceptionI agree. You can't append to a file written with an ObjectOutputStream. You would have to read it all in, write it all out again and write the new object. You're better off keeping the file open while you still have objects to write to it.
while ((temp = (Storingobject) objIn.readObject()) != null) {ObjectInputStream.readObject() only returns null if you wrote a null. If you're not writing nulls, the correct technique is to loop until you get an EOFException. I don't favour explicitly writing a null just to get around this as suggested above, as it means you can never write a null for any other purpose.

Error:SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: Server was unable to read request. --- There is an error in XML document (1, 447). --- Input string was not in a correct format.

Hi All,
We have a scenario of FTP-->PI---> Webservice. While triggering the data in the FTP, it is failing in the PI with the below error
SOAP: response message contains an error XIAdapter/PARSING/ADAPTER.SOAP_EXCEPTION - soap fault: Server was unable to read request. ---> There is an error in XML document (1, 447). ---> Input string was not in a correct format.
Can you please help?

Hi Raja- It seems to be a data quality issue.
Check for the value @ 1447 position in the xml message that you are trying to send to web service..
may be a date filed/decimal value which is not in expected format.
