How to catch the user defined exception in application service

Hi All,
How to catch the user defined exception in application service when it is throwed by the external service..
Regards,
Thirumurugan.

Hi,
    Thanks for your reply,
        Actually I am calling validate Login method of External service from the application service. When the login fails, my external service will throw user defined Exception.I want to catch the user defined Exception.
    But in the application service , validate Login method can catch only Invocation Exception and Engine Exception.
   These two exception are present in the Application service remote interface.
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException;
User defined exception is not present there. When i include the webservice as external service in CAF, it suppossed to generate the java file for the custom exception of validate Login method and this generated file should be included in the application service remote interface..
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException,
(generated file name of user defined Excpetion.
Then only validate login method of application service can catch the user defined Exception which is thrown by the external service.

How to let the user define the colors for each plots in the graph (I use LabVIEW 7)?

How to let the user define the colors for each plots in the graph (I
use LabVIEW 7)?

Hi,
Take a look at this example, it uses property nodes to select tha
active plot and then changes the color of that plot.
If you want to make the number of plots dynamic you could use a for
loop and an array of color boxes.
I hope this helps.

PL/SQL Using SQL%NOTFOUND to raise a user defined exception in a function

I have written the following function for finding the number of items in stock in the item table.
CREATE OR REPLACE function getAmount (ItemID IN NUMBER)
RETURN NUMBER
AS
invalid_id EXCEPTION;
returnedQty number;
BEGIN
Select qty
Into returnedQty
From item
Where itemNo = ItemID;
RETURN (returnedQty);
IF SQL%NOTFOUND THEN
RAISE invalid_id;
END IF;
COMMIT;
Exception
WHEN invalid_id THEN
DBMS_OUTPUT.PUT_LINE('Invalid ID entered');
END getAmount;
The function compiles successfully, although there is a problem that Oracle is not handling my user-defined exception invalid_id
If I use the following for a valid itemID:
DECLARE
return_value number;
BEGIN
return_value := getAmount(1);
DBMS_OUTPUT.PUT_LINE (return_value);
END;
then the function returns the quantity of items in stock correctly.
However, if I enter an incorrect itemID, say 20
DECLARE
return_value number;
BEGIN
return_value := getAmount(20);
DBMS_OUTPUT.PUT_LINE (return_value);
END;
The invalid_id exception is not raised, and the Oracle errors says: no_data_found and the function has not returned a value. If I add a no_data_found exception, this works perfectly, but for this assignment I must write my own user-defined error.
Any help would be very much appreciated!
Thank you.

What you're trying to do, is to use an implicit cursor. Implicit cursors will raise no_data_found and too_many_rows in case of an error. Explicit cursors will not.
Also, you have a small coding error ... a little rewrite and your code will do as you want to:
CREATE OR REPLACE function getAmount (ItemID IN NUMBER)
RETURN NUMBER
AS
invalid_id EXCEPTION;
returnedQty number;
cursor citem is
Select qty
From item
Where itemNo = ItemID;
fnd boolean;
BEGIN
open citem;
fetch citem Into returnedQty;
fnd := citem%found;
close citem;
if fnd then
RETURN (returnedQty);
else
RAISE invalid_id;
END IF;
/* Do not catch your own exception or the calling code will not receive it.
Exception
WHEN invalid_id THEN
DBMS_OUTPUT.PUT_LINE('Invalid ID entered');
END getAmount;
Your problem is, you're not using a package. This means, that the calling code has no way of catching this user-defined exeption. The correct way is to define a package, define the userdefined exception in the package and refer to it in your code:
create or replace package amt
is
invalid_id EXCEPTION;
function getAmount (ItemID IN NUMBER)
RETURN NUMBER;
end;
create or replace package body amt
is
function getAmount (ItemID IN NUMBER)
RETURN NUMBER
AS
returnedQty number;
cursor citem is
Select qty
From item
Where itemNo = ItemID;
fnd boolean;
BEGIN
open citem;
fetch citem Into returnedQty;
fnd := citem%found;
close citem;
if fnd then
RETURN (returnedQty);
else
RAISE invalid_id;
END IF;
end;
end; -- end package
To do a simple test, you'll do:
declare
a number;
begin
a := amt.getAmount(123);
dbms_output.put_line('The result is '||a);
exception
when amt.invalid_id then
dbms_output.put_line('ID not found');
end;
Other ways is to raise the exception in your no_data_found block.
But I'm REALLY puzzled if there's really someone out there who prefers a user-defined exception instead of the clearly defined NO_DATA_FOUND exception.
I can't be sure of course, but are you sure what they mean is they don't want ANY exception? That's a pretty common requirement.
In general - explicit cursors are a bit faster because Oracle does not have to do a second fetch to determine TOO_MANY_ROWS. And it's not too much additional writing. Explicit cursors will never raise exceptions - unless you use dynamic sql and your SQL is invalid.
Good luck

How to bind the user-defined watch to a specific server so that server's Health would show green ball and is linked to Monitoring watch?

Hi,
I create a user defined watch for BI4.1 ExplorerExplorationServer server in CMC -> Monitoring.
Caution:
node.ExplorerExplorationServer$'Server Running State'==1 ||
node.ExplorerExplorationServer$'Server Running State'==2 ||
node.ExplorerExplorationServer$'Server Running State'==4 ||
node.ExplorerExplorationServer$'Server Running State'==6 ||
node.ExplorerExplorationServer$'Server Running State'==7 ||
node.ExplorerExplorationServer$'Health State'==1
Danger:
node.ExplorerExplorationServer$'Server Running State'==0 ||
node.ExplorerExplorationServer$'Server Running State'==5 ||
node.ExplorerExplorationServer$'Health State'==0
However, in CMC -> Servers -> Explorer Services, the ExplorerExplorationServer shows "Information is not available" blue ball in Health.
How do I bind the user-defined watch to a specific server so that server's Health would show green ball and is linked to Monitoring watch?
Regards,
Jin-Chong

Hello JinChong,
We had created User-defined Explorer watches on our environments and have run into issues.
Have received many false alerts even though Explorer servers are running fine.
After creating an AGS case it was informed to us that Explorer does not have monitoring capabilities.
AGS is checking with solution architect of Explorer application about when the monitoring watches for explorer would be included.

How to distinguish the User-Defined-Function from Oracle Build-In function

Hi Friends,
I could get the function list form all_objects table by the SQL:
select * from all_objects where object_type = 'FUNCTION'
but there is no column in all_objects specify the function is build-in or user-defined.
But I found in SQL Server there is a column "is_ms_shipped" in the sys.all_objects table. This column will specify the object is build-in or user-defined. I want to get the equivalent column in Oracle but failed.
Could anyone tell me how to solve this problem?
Thanks,
Ricky

Thanks Pavan.
But if an user connects to database using "conn /as sysdba" syntax and creates a function. This user-defined funtion goes into the "SYS" schema also. I know it is not the best practise to create objects using sys user so I think your solution is right.

Ricky

In java ,how to access the user-defined type of pl/sql?

in my application,i using the following code to access the pl/sql type self-defined,but it throws run-time exception,how can i resolve it?String sqlStr="{call BossStat.dunStat(?,?,?,?,?,?)}";
OracleCallableStatement ocstmt=(OracleCallableStatement)conn.prepareCall(sqlStr);
int paramIndexInt=1;
ocstmt.setInt(paramIndexInt++,100);
ocstmt.setInt(paramIndexInt++,1);
ocstmt.setInt(paramIndexInt++,1);
ocstmt.setTimestamp(paramIndexInt++,new java.sql.Timestamp(System.currentTimeMillis()));
ocstmt.setTimestamp(paramIndexInt++,new java.sql.Timestamp(System.currentTimeMillis()));
ocstmt.registerOutParameter(paramIndexInt++,OracleTypes.ARRAY,"BossStat.TP_STATLABELVAR");
ocstmt.execute();

You can have a look at this how to document
http://otn.oracle.com/sample_code/tech/java/codesnippet/jdbc/objects/ObjectTypes.html
You can apply similar concept if you want to use stored procedure.
If you still get problems, post the type that you have created and the error you are getting.

i rectify this
Regards

hi
i think don't use set parameter value, use there SUBMIT & RETURN statement and write in USER_COMMAND function.
FORM USER_COMMAND USING P_UCOMM LIKE SY-UCOMM
P_SELFIELD TYPE SLIS_SELFIELD.
SUBMIT program name AND RETURN
WITH <selection-screen field> IN <selection-screen field>
WITH WERKS IN WERKS .

How to handle user defined exception from C#?

Hi:
I have some PL/SQL code that will throw a user defined exception if certain conditions are met. How do I handle user defined exceptions if this procedure/function is being called from C#? C# can handle a normal Oracle SQL error (e.g. ORA-XXXX) because they are defined in the proper class, but how do I get it to know about my user defined exception? Does anyone have any links to examples of doing this?
Thanks.

Hi Gaff,
Is there a particular problem you're having doing this? It works as normal for me...
Cheers

Propagating user defined exceptions

A question on marshalling user defined exception in RMI/IIOP. Consider the following simple Java interface and user defined exception:
public interface OrderProcess extends Remote {
String placeOrder(PO order) throws OrderException, RemoteException;
public final class OrderException extends java.lang.Exception implements java.io.Serializable {
public OrderException() { }
public String msg;
public OrderException(String _msg) {
msg = _msg;
If the client uses RMI/IIOP to access a CORBA server( client uses the rmi stubs generated by rmic -iiop, the server uses Dynamic Skeleton Invocation by implementing org.omg.CORBA.DynamicImplementation), how does the server send back the user defined exception OrderException so that it can be unmarshalled properly by the client stub? Here is a section of the rmi stub generated by JDK1.3.0, note it looks for an exception OrderEx and OrderException:
public String placeOrder(PO arg0) throws OrderException, RemoteException {
if (!Util.isLocal(this)) {
try {
org.omg.CORBA_2_3.portable.InputStream in = null;
try {
org.omg.CORBA_2_3.portable.OutputStream out =
(org.omg.CORBA_2_3.portable.OutputStream)
_request("placeOrder", true);
out.write_value(arg0,PO.class);
in = (org.omg.CORBA_2_3.portable.InputStream)_invoke(out);
return (String) in.read_value(String.class);
} catch (ApplicationException ex) {
in = (org.omg.CORBA_2_3.portable.InputStream) ex.getInputStream();
String id = in.read_string();
if (id.equals("IDL:RFQSample/initial/rfqTypes/OrderEx:1.0")) {
throw (OrderException) in.read_value(OrderException.class);
throw new UnexpectedException(id);
} catch (RemarshalException ex) {
return placeOrder(arg0);
} finally {
_releaseReply(in);
} catch (SystemException ex) {
throw Util.mapSystemException(ex);
} else {
ServantObject so = servantpreinvoke("placeOrder",OrderProcess.class);
if (so == null) {
return placeOrder(arg0);
try {
PO arg0Copy = (PO) Util.copyObject(arg0,_orb());
return ((OrderProcess)so.servant).placeOrder(arg0Copy);
} catch (Throwable ex) {
Throwable exCopy = (Throwable)Util.copyObject(ex,_orb());
if (exCopy instanceof OrderException) {
throw (OrderException)exCopy;
throw Util.wrapException(exCopy);
} finally {
servantpostinvoke(so);

Not sure exactly if that's what you are asking but the unmarshalling of your OrderException happens in this catch block:
catch (ApplicationException ex)
                    in = (org.omg.CORBA_2_3.portable.InputStream) ex.getInputStream ();
                    String id = in.read_string ();
                    if (id.equals ("IDL:RFQSample/initial/rfqTypes/OrderEx:1.0"))
                        throw (OrderException) in.read_value (OrderException.class);
                    throw new UnexpectedException (id);
                }the ApplicationException class is the vehicle that transports your exception instance across the wire. You can dig further into the implementation to see how it is done.

In which of the following sections of a PL/SQL block is a user-defined exception raised?

Hi,
A (somewhat elementary) question:
In which of the following sections of a PL/SQL block is a user-defined exception raised?
a) Exception section
b) Declarative section
c) Error handling section
d) Executable section
I'd be interested to hear people's answers.
Thanks.

As Etbin already noted, there are only 3 sections and user-defined exception can be raised in any of them. User-defined exception raised in declarative section example:
declare
    year_zero exception;
    pragma exception_init(year_zero,-01841);
begin
    declare
        v_dt date := to_date(1721420,'j');
    begin
        null;
    end;
exception
    when year_zero
      then
        dbms_output.put_line('Year 0!');
end;
Year 0!

How to use user defined exception class

Hi all
I just need som help with creating a user defined exception class.
Im writing a small/simple text editor.
My exception class looks like this:
public class myExcp extends Throwable
     private String message;
     public myExcep(String message)
          this.message = message;
     public void display()
          System.out.println(message);
I would like to use it when a user tries to open a exe-file instead of a txt file.
Here is some code from the editor:
if (e.getSource() == open)
saveOld();
if (fc.showOpenDialog(null)== JFileChooser.APPROVE_OPTION)
readFile(fc.getSelectedFile().getAbsolutePath());
saveas.setEnabled(true);
So, should I use exception here or at the readFile method?
readfile:
private void readFile(String fileName)
try
String tmp = fileName.substring(fileName.length() -4, fileName.length());
if (!tmp.equals(".exe"))
FileReader r = new FileReader(fileName);
textarea.read(r, null);
r.close();
currentFile = fileName;
label.setText(currentFile);
changed = false;
catch (IOException e)
JOptionPane.showMessageDialog (this, "Cannot find the file " + fileName);
Where and how do I use my exception class.
Do I need to create an instance? Where?
Should the exception class extend Exception instead?
Thank you in advance /

Extend Exception, not Throwable. It's a checked exception that way.
Follow the Sun coding standards and make that exception class name start with a capital letter.
When you extend Exception, override all four ctors.
What's that display method you added? Isn't getMessage() good enough?
You need to create a new instance just before you throw the exception, of course.
Sounds like a terrible design, by the way. Exceptions shouldn't be used like "go to" for app logic. They should signal unrecoverable conditions. You can easily recover from the situation you've described simply by displaying a pop-up that tells the user to open only text-readable file types. I think that's a better solution.
