Own exception and to trigger

Hi
Is possible to declate a exception and automatically to trigger ?

THE WAY what is utility PRAGMA
EXCEPTION_INIT ?it like user defined exception
somthing like this?SQL> ed
Wrote file afiedt.buf
1 DECLARE
2     -- name for exception
3       e_emps_remaining EXCEPTION;
4     PRAGMA EXCEPTION_INIT(e_emps_remaining, -20002);
5 BEGIN
6     raise_application_error(-20002, 'remaining');
7 EXCEPTION
8     WHEN e_emps_remaining THEN
9     DBMS_OUTPUT.PUT_LINE ('sql code error :'||sqlcode||' : '||sqlerrm);

How can I define a own exception

Hallo,
I want to delete rows in a table after pressing the "Delete"-Button.
When pressing "delete" the message box htmldb_delete_message is shown.
When pressing "Ok" the row will not deleted if there are depending rows in another table. On the Form the Error "ORA-02292: Integritäts-Constraint (EV_ADM.SEM_TEILNAHME_PN_FK) verletzt - untergeordneter Datensatz gefunden" is displayed. For this ORA--message I want to create a own exception and displays a message that the user can understand. How can I do this?
Thanks, Daniela

Difference between before and after trigger

    Is there any difference between these two trigger .
    If its there , then please tell when we should use before trigger and after trigger
   thanx
   young bro


BEFORE Triggers
BEFORE triggers run the trigger action before the triggering statement is run. This type of trigger is commonly used in the following situations:
When the trigger action determines whether the triggering statement should be allowed to complete. Using a BEFORE trigger for this purpose, you can eliminate unnecessary processing of the triggering statement and its eventual rollback in cases where an exception is raised in the trigger action.
To derive specific column values before completing a triggering INSERT or UPDATE statement.
AFTER Triggers
AFTER triggers run the trigger action after the triggering statement is run.
Trigger Type Combinations
Using the options listed previously, you can create four types of row and statement triggers:
BEFORE statement trigger
Before executing the triggering statement, the trigger action is run.
BEFORE row trigger
Before modifying each row affected by the triggering statement and before checking appropriate integrity constraints, the trigger action is run, if the trigger restriction was not violated.
AFTER statement trigger
After executing the triggering statement and applying any deferred integrity constraints, the trigger action is run.
AFTER row trigger
After modifying each row affected by the triggering statement and possibly applying appropriate integrity constraints, the trigger action is run for the current row provided the trigger restriction was not violated. Unlike BEFORE row triggers, AFTER row triggers lock rows.
You can have multiple triggers of the same type for the same statement for any given table. For example, you can have two BEFORE statement triggers for UPDATE statements on the employees table. Multiple triggers of the same type permit modular installation of applications that have triggers on the same tables. Also, Oracle materialized view logs use AFTER row triggers, so you can design your own AFTER row trigger in addition to the Oracle-defined AFTER row trigger.
You can create as many triggers of the preceding different types as you need for each type of DML statement, (INSERT, UPDATE, or DELETE).

When i open an mp3 file from a source other than apple, does itunes create it's own file and can I then delete the original mp3?

when I open a music file from a source other than apple, does itunes create it's own file and can I then delete the original mp3?

If you use iTunes' default settings then when you add a file to iTunes it places a copy of the file in the iTunes media folder and it leaves the original in place. The exception is when you drag it to the Automatically Add To iTunes folder.
It does not convert the file. You can delete the original if you wish.

Using Java Embedding Unzip Code and a Trigger File in a BPEL Process

Hello,
Thanks in advance to anyone that contributes with any insight. It is much appreciated. Having said that I will get to the crux of my problem.
I am currently using Oracle 11g. I have created a SOA composite application that incorporates BPEL and Java. I have the code needed to unzip and extract compressed folders. However, when this was first built out using BPEL it automatically created a web service in the "exposed service" lane and not a file adapter which I believe is needed in order to trigger the process via a start.txt file for example. Based on what I know ... this web service automatically connecting to the BPEL process was simply due to the order of operations, etc. So by creating a 'read' file adapter first and then creating the BPEL process and selecting the template "Define Service Later", it does not automatcially connect the web service to the BPEL process and it will allow me to connect a file adapter to this BPEL process instead ... great. When opening up the BPEL file I then connect a recieve component to this file adapter and configure appropriately.
Essentially, my objective in setting up a trigger to start this unzip process is due to the BPEL process before that outputs or writes the .zip folder to the same directory that I want to poll and/or trigger via a start.txt file. I can get this process to work with a webservice connecting to the BPEL process and by using a Java Embedded in BPEL file, which in turns calls the package/ class that has the java code needed to unzip.
For some reason whenever I try to use a file adapter instead of the native web service that gets created (as mentioned above) it doesn't work. It seems to build or compile just fine however, I am getting errors when I try to deploy.
Note: The Java code contains all the paths where the zip file is to be taken from and extracted to. So because this is in the code I don't need the file adapter to handle this. I just want to use the file adapter so that I can trigger the process via start.txt or something of that nature.
Thanks to anyone that has any suggestions.
Kind Regards,
Kevin

SOAP to FILE using BPM to catch exception and save error into the table

Hi All
My scenario SOAP to FILE using BPB is working fine but now I have a requirement to catch an exception if something wrong happened on a runtime and save it into the tracking table, is that possible, if it is please point me to the similar step by step scenario.
Thanks in advince,
Yonela

Yonela:
As your original requirement is to save the eorr data into your database table, however, you was mis-leaded to alerting field.
You are using BPM now, then that is the reason that I suggested to use excpetion branch.
It does not matter SOAP to File seneario, it does not have to be SAP - RFC scenario, your BPM willl interact with database system.
First you have block which include all the steps that possible generate exception: like Transformation step, and your final Aync send step (which will send data to file).
Secondly, define a exception handler for that block.
3. Modify each steps that posssible generate exception: e.g. transformation step, send step, add exception handler to them.
4. Create exception branch in side the block
5. Add another send step inside your exception branch, which will call RFC, RFC will write data to your table.
6. If you want, you can add a control step in exception branch to trigger a alert, or terminate current process.
At run time, any steps that trigger exeption,will cause your exception branch executed, and RFC will be called to insert data into your database table.

Creating own Exception class

In my past paper it says...
Show how to create your own Exception class that derives from class Exception. The class should provide a default constructor which allows a "My Error message" message to be set, and a second constructor which has as an argument the error message. 4-MARKS
Does this look right..?
public class MyExcep extends Exception
     public MyExcep()
          super("My Error Message");
     public MyExcep(String message)
          super(message);
}

Yes. Do I get 4 marks now? or is it Four Marks?

HT1329 Why do we bother with ipod?? I had to change my computer and now my library containing my own music AND ipod purchased music is all dissagrregated. NEVER AGAIN!!!!!!!

Apple, you HAVE to get a little more customer friendly about the music we buy. We also have our own music and when we download it guess where it goes? into my Apple library. PS That's mine. To make our life difficult your protocols will not allow me to simply "move" my ENTIRE itunes library to my new computer. Why the heck not?? Explanation please. And not because there are other steps you created. Why do you not ALLOW it? Want me to repurchase or reload music I already put on there? Geeezzz.
PS the result.............I havent been able to buy nor am I now inclined to buy more music because....I cant. Good thing I put some good good playlists on my IPOD because it seems its now a portable CD.
Not Happy.

Can't tell you exactly, as it can be used to facilitate piracy and Apple blocks this sort of thing from occuring (except for itunes purchased music)
But you can find out what your looking for at iLounge, i'd suggest that method for "mixed" music from different sources, that way you get it all back.
Next time, hit the iTunes menu and backup your library to disks, only takes a few minutes and a few DVD-R's.
Good Luck

Passing of old and new trigger details to a generic function or procedure

Hi all.
I have a requirement to pass all the new and old column information from a database trigger ( for the purposes of this discussion, it will be a before row, insert, update and delete trigger) to a procedure/function ( either is fine).
My first thought was to create a separate routine for each table I wish to implement this in, which has a new and old input parameter for every column, however I realised I needed a solution where the called routine needs to be generic (because we'll let other developers call the same routine and we dont want them to have to create their own version for their table).
This presents a problem as every table I wish to implement this on could have a completely different amount of columns (and dataypes). The called routine will operate under a pragma autnonmous_transaction (as it will be performing commits) so I need to pass all the fields across in one go.
Another idea I had was to create an type object with (potentially) 300 generic fields that I assign the values to and pass that as a parameter, however I could never know before hand what datatypes are needed, CLOBS, DATE, VARCHAR, etc...
Does anyone have any ideas on how I can accomplish this with a generic routine?
Regards,
Greg.

Here's a link that has some simple examples just for ANYDATA - http://orafaq.com/node/1853
TOOLKIT ALERT - Here is a classic link you will want to keep - How to pipeline a function with a dynamic number of columns?
I asked in another thread if they could create a locked TOOLKIT thread (like report abuse here - a global one for mods only) to put these nuggets in one place.
see ascheffer's responses where he shows how to create a pipelined function that call return a result set with a different (dnynamic) number of columns for different calls! It uses functionality in the
ANYTYPE - metadata
ANYDATA - data with metadata
ANYRESULTSET - A resultset where every column is of type ANYDATA - meaning whatever you define it to be.
Rough overview - The cartridge exposes some interface functions (3-5 are typically needed) that you implement in a procedure. See scheffer post for his procedure:
static function ODCITableDescribe( rtype out anytype, p_parm in varchar2, p_rows_req in number := 2 )
return number,
static function ODCITablePrepare( sctx out NColPipe, ti in sys.ODCITabFuncInfo, p_parm in varchar2, p_rows_req in number := 2 )
return number,
static function ODCITableStart( sctx in out NColPipe, p_parm in varchar2, p_rows_req in number := 2 )
return number,
member function ODCITableFetch( self in out NColPipe, nrows in number, outset out anydataset )
return number,
member function ODCITableClose( self in NColPipe )The TableDescribe does just what it's name says.
Oracle calls these functions to get the metadata about your custom types, to describe and return result sets.
Are you familiar with VARIANTs that are used in COM programming? A variant is a 16 byte object (record) type. 2 bytes contain the 'type' of the variant (int, char, etc) and other bytes contain data of that 'type'. It is a generic container that can hold any type of data.
The ANYTYPE, ANYDATA and ANYRESULTSET are roughly analogous to that.

N00b query: Why would anyone ever want to define their own Exception class?

I've been reading thru my Java textbook for the past couple hours.
Exceptions are a wonderful thing. I already found several instances where I could've implemented try/cacth in my earlier programs.
Anyway, getting back to the point. My question is, can someone give me a realistic situation/example where a custom Expcetion class is REQUIRED? (the key word here is "required"!)
I can see why someone would want to have his own Exception class..... e.getMessage() as custom error messages are SO DAMN COOL!!!!!! :P
hehe
But seriously, if you are making intermidiate/advanced Java programs, would you ever REQUIRE to make your own Exception class? Afterall, even a custom made Exception class always "extends" from a pre-defined Java class, right?
Let me make this a bit more clear... public class CustomException extends IOException{ }Now, if I am making a try/catch statement, I can simply say
try{
throw new CustomException;
catch (IOException e) { }
Now as you can see, the CustomException was caught by the catch claus, because IOException is the superclass of CustomException. So, in other words, the whole CustomException thingy didnt do anything useful.
I know I know, I am so naive. Enlighten me >.<

Sure. Say you want to have a system where you want to include a custom error code which maps to some internationalized error messages. You would create an Exception subclass with a field to hold that value separate from the normal "default" message. Then you could throw that exception in all your code. Other code can catch it as a plain Exception if they want and use the "default" message, which is okay if they don't really care about the error code.
I don't think you are ever "required" to make your own exceptions. I have done so, but I don't often. It depends. See, there are plenty of Exception subclasses in the standard packages, and most of them cover many of the things you need. So more often if I'm throwing an exception, I'll be using the already existing ones, like IllegalArgumentException or IOException (whatever is relevant to the code).
Yes, you can do what you did below with CustomException. However the reason you might do that is cuz you really want to do this:
try {
 // call some code that may throw IOException from some standard IO package
 // or may throw CustomException from some of my methods...
} catch (CustomException ce) {
 // handle cusotm exception
} catch (IOException ioe) {
 // handle IO exception
}Cuz you may want to differentiate between your exceptions vs. IOExceptions that might be thrown from some java.io class.
Usually when you use an exception class it's a named class that relates to some condition. It may hold additional information besides the standard message, but I think most of the time it's just the class name which describes the problem. And if there isn't one that describes the problem that you're code might encounter, then create a subclass.

How to customize the title bar on my own Look And Feel?

Hi all!
I am creating my own Look and Feel which extends from NimbusLookAndFeel. What I'm doing is overwriting UIDefaults values??, referring to the Painters. For example:
+uiDefault.put ("Button [Enabled]", new ButtonEnabledPainter());+
But now I need is to customize the title bar of the JFrame's, but I do not see this option in Painter's values ??can be overwritten by Nimbus (http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/_nimbusDefaults . html).
You know as possible? I have to overwrite an existing UI component? The idea is I want to make the look and feel like SeaGlass, but the code seems a bit complex to know where to begin.
I hope you can guide me on this issue.
Thank you very much for everything! And excuse my English!.

Chart display and camera trigger

Hello,
I’m new to Labview and using it for my thesis to acquire data and initiate the image capturing of a camera. But I came across some problems with the data display and camera trigger, if anyone could offer some advice
My Hardware consists of a MC-USB-2404-UI DAQ-device (including MCCdaq-Drivers with Ulx-Libary and an extra LV vi pallet), a thermocouple type K and a TEMATEC pressure sensor MAP350-S / F (0-10V/0(4)-20mA). Since the DAQ-device supplies itself through USB with just 5V Power, I connected the pressure sensor in series with an additional 10V power supply unit.
The VI that I am constructing should read the measured values (pressure and temperature) and display them in a chart and on a numerical indicator. Above 200°C and 200bar the data logging should be manually started and a high-speed camera simultaneously triggered. Apart from the camera trigger, the VI is almost complete except for a few problems with measuring the value display.
Here are my problems:
1) How can I initiate the camera simultaneously with the data logging? Since the hs camera will capture more than 1000fps, I would restrict the image acquisition to a simple trigger that initiates the capturing. The appropriate VI’s IMAQ and IMAQdmx are already available. Should I create a new loop and connect it to my case-structure through a Rendezvous? And what kind of vi’s do I need for a simple trigger?
2) Also I couldn’t figure out how to convert 1D-Array of Waveform to DBL or at least how to connect the data wire with a numerical indicator. The indicator is crucial for the manual start of the data logging.
3) Another problem is with the chart display. As soon as I start the data logging, the graph disappears and the chart displays only n-samples of the currant loop pass. The enlargement of the chart length history brings no improvement. Before the data logging is started the charts are showing the all points from the start. So what changes when I Press “Aufnahme starten” (start acquisition)?
Any ideas would be much appreciated.

Hello annaei,
thanks for your quik help... the numeric indicator is now implemented. thanks to you.
Explaination:
1) I have construkted an experimental vessel, which builds up pressure through a stamp. There is a heating jacket around it and on the bottom is a sight glass to capture the intirior with a highspeed camera. The starting conditions for the experiment are 200bar and 200°C. So I will need to monitor the current state of the intirior to know when i can start the actual data logging. With the data logging i want to start my image acquisition silmutaneasly.
3) For the Chart problem i attachted two pictures... After experimenting with the sample clock, reading vi and timing of the loop, i figured out that the greatest influence is the loop timing.
At 250ms (wait Xms multiple for loop pass) there is all data displayed even if i press the data logging button. At 100ms i was logging the data from 5s on and as one can see in the picture below the graph disappears after 28s. At 20ms loop pass interval the graph disappears randomly and with the data logging activated it is just a single point displayed.
In general the 250ms loop pass interval is a totally suitable solution for me, but i just can't help the feeling that the problem is not resolved. And i would like to know what i am doing wrong or what i could do better.
Thanks, Tobi.

Define our own Exceptions in th function builder

hi
how to define our own Exceptions in th function builder in the Exception tab and how to use them in functon definiton.
regards
ravish

Hi,
Exceptions
The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.
The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.
The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.
Note
For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.
Regards,
Padmam.

Exception in Oracle Trigger in Java

I have a java trigger loaded in my Oracle database. In the trigger, I throw an exception and, when the trigger is run, the exception is caught by the JVM and the following error occurs:
ORA-29532: Java call terminated by uncaught Java exception: br.com.medisoft.sga.trigger.exception.MedisoftTriggerException: Mensagem DBA-1
The SQL statement is executed in an EJB using JDBC. Is there any method to catch the exception thrown by the java trigger (in the example, MedisoftTriggerException) and it's methods?
The MedisoftTriggerException is an subclass of SQLException.
I tried the following:
try {
} catch ( SQLException ex ) {
I can catch an SQLException, but with the following data:
ex.getMessage () => ORA-29532: Java call terminated by uncaught Java exception: br.com.medisoft.sga.trigger.exception.MedisoftTriggerException: Mensagem DBA-1
ex.errorCode () => 29532
ex.getNextException () => null.
I want to get the data from exception br.com.medisoft.sga.trigger.exception.MedisoftTriggerException, that was the really thrown exception in the trigger. Is there another way than to use the substring from ex.getMessage() ?
Thanks,
Jonatan Schroeder

Sorry, wrong forum.

Defining own exception

Hi,
I need to create an exception that will be thrown if a call to function x returns a negative value. I assume that means I need to create my own exception class. However, everything I've read about creating one's own exception class involves merely changing the text thrown by a given exception. How does one actually define an exception which says "Throw this when x is a particular value"?
Any suggestions?
Cheers,
Didje

You detect the fault yourself, and throw it. Eg
public class NegativeException extends Exception {
public NegativeException() {
super("negative number");
// in code elsewhere
if ( getValue() < 0 ) throw new NegativeException();
