TO_NUMBER do not throw an exception on an invalid entry.

I have problems safely convert text to numbers with TO_NUMBER function values.

select to_number('BAD') from dual

Result: ORA-01722: invalid number. It's logical.

select to_number('6E9547') from dual

Result: ORA-01722: invalid number. This makes sense too given that the E is considered to be a marker of the exhibitor.

If I create a function to check if a number is valid:

CREATE OR REPLACE FUNCTION is_number( str IN VARCHAR2 ) RETURN NUMBER IS
    BEGIN
     RETURN TO_NUMBER(str);
    EXCEPTION
     WHEN OTHERS THEN RETURN NULL;
    END;

Now it's time for a new trial:

select is_number('BAD') from dual

Result: NULL as expected

select is_number('6E9547') from dual

Result: 1E126
The latter is unexpected. I expect NOTHING but get you a number of "random"?

All this on 10.2.0.4 (patch set 20) on Windows 2003 server.

Why a sql statement throwing an error and the pl/sql only?

436548.1 said

»
A SELECT simple for a sum to DOUBLE returns ORA-01426: digital overflow, that is correct.
«

and

»
Insert "infinite" by means of link PLSQL does not throw an error - it should report ORA-1426.
«

So I guess this bug has already been processed and plsql should also throw an error (by design) above examples.

Persist does not throw an exception in a JUnit test
I implement a JUnit test by using Toplink JPA provider. I must be missing something because I try to keep twice the same entity and no exception is thrown. PersistenceException, nor any other type of exception. The code can not be easier:

@Test
Public Sub testAddExistingTeam() throws Exception {}

Team = new Team ("team2");

try {}

EntityManagerFactory emf =
Persistence.createEntityManagerFactory ("Fisher");
EntityManager em = emf.createEntityManager ();

em.getTransaction () .begin ();

EM. Persist (Team);
EM. Persist (Team);

em.getTransaction () .commit ();
EM. Close();
}
catch (Exception e) {}
e.printStackTrace ();
}

}

Note the two em.persist (team).

This code does not enter into the catch block or produce any kind of exception. On the other hand, I checked after the first
EM. Persist (Team); the team is really successful.

The relevant parts of the team following class definition:

@Entity
@Table (name = 'TEAM')
Team/public class implements Serializable {}
@Id
@Column (name = "NAME")
private String name;

@ManyToOne
@JoinColumn (name = "CLUB_NAME", referencedColumnName = "NAME")
Club private;
category private;
private String email;

@ManyToMany (mappedBy = "teams")
list < competition > competition private;

public Team (String name) {}
myIdName = name;
This.Club = null;
This.competitions = new ArrayList < competition > ();
}

more than builders...getters/setters...and.
}

I'm really intrigued by this problem. Could someone help? I would be really grateful!

Josepma
This is expected behavior as persist is a no - op if called on one managed entity (other than to the waterfall on relationships with cascade. Persist), and the first call to persist makes the past in team managed entity.

Try calling em.flush (); and em.clear (); between calls persist to get an exception.
The first flush will ensure that the team is inserted into the database, while that clear it peel while the second call persist will attempt to insert the team. JPA providers should not throw the entityExistsException persist - it can be delayed until the transaction either emptied or committed, then you are likely to get a PersistenceException validation instead of EntityExistsException to persist.

NI488.2 throws an exception

I'm controlling a cold room using c# application via the Instrument National .NET assemblies. My obversations are:

1. software development - works PERFECTLY with the Instrument.

2. computer deployment - (installed NI488.2 + NIVISA drivers)-throws an exception (see below) when running my c# application

3. computer deployment - (Using NIMAX - Instrument works perfectly) - I also double checked the port settings.

Versions used in development computer - NI488.2 (8.9.35.104)

The versions used in the deployment computer - 2.24 OR-488. 2 + NI-VISA 4.1 + NI-VISA DURATION 5.0.2

Hello

You have it listed for GPIB software versions

Versions used in development computer - NI488.2 (8.9.35.104)

The versions used in the deployment computer - 2.24 OR-488. 2 + NI-VISA 4.1 + NI-VISA DURATION 5.0.2

The 8.9.35. 104 is the version of the .NET library.

The 2.24 is the version of the software to control GPIB (dll)

Make sure that the deployment machine, you are having issues with that has a version of the DLL that is the same or higher than the development computer.

Look under "Software" in the NOT-MAX.

The function call should throw two many line exception?. Why search is not throw it away

Your extraction to retrieve the first row of the cursor.

However, your cursor is based on a select statement that has no order, so the 'first' record will be whatever happens to come first, and that could be one of the records in the table.

Need to throw an exception after a test of text corresponding to the openscript

Hello
I want to check a text using text matching test and I want to throw an Exception if the text is not there. If the text is there she must either continue normally.
I tried this test of text matching. According to this, it's getting abandoned after
() Web.document
"\"/web:window[@index='0 "or @title ='Oracle BI interactive dashboards - Advance Planning']/web:document[@index='0']\" ").
.verifyText ("Check result", "export",
Source.DisplayContent, TextPresence.PassIfPresent,
MatchOption.Exact);
After this way can anyone please explain me (code)
Concerning
Harsha

If you give verifyText(), script not give up failure, IE. script displays a warning text not found in HTML content

If you give assertText(), the script will stop in case of failure.

To throw an exception when the text is not found, use try-catch as follows...

try {}

Web.Window ("/ web: window [@index = '0' or @title = 'Oracle BI interactive dashboards - Advance Planning']/web:document[@index='0']")

.assertText ("Check result", "export",

Source.DisplayContent,

TextPresence.PassIfPresent,

MatchOption.Exact);

}

catch (System.Exception e)

{

failure ("could not find the export text");

}

See you soon,.

Exception handler, not shot context except for the Subscriber to events
Hello

Is it possible to make the activity of the exception handler when an exception is thrown by the Subscriber to the contextual events?

In my application, as well a parent workflow and a child task flow (a task with fragments of page that is inserted into the parent company) have some activity of the exception handler.
When an exception is thrown by one method other than the Subscriber to contextual events (for example, the action listener), the activity of the exception handler is triggered as expected.
However, when the parent task flow publises a contextual event which is underwritten by the child workflows and the Subscriber throws an exception, the exception handler is triggered neither the parent nor the child workflows.

Any help is appreciated.

Thank you
Kenji
Hello

function when the exception is thrown. The ADFc exception handler does not fire for exceptions that occur during the RENDER_RESPONSE phase (so it is one thing to check). In this case you must use a try-catch block. It also depends on what is exactly raining the exception (e.g. What is the bean of the code where the Manager, or a problem on the producer, is the involved link layer, etc.).

Throws an Exception when there is no update.
Hi friends,

I have page search and update the page, I am selecting a record in the search page and go to
Update page to update a record, but if the user makes no changes to the record, then I
you want to throw an exception saying there is no change to be saved.

Any suggestion, how can I do this challenge?

Thanks in advance.
Keerthi.k
Keethi

The approach is like that...

When the user navigates to update the page and click on the button Save. You handle this event in the method of the pfr and calling a method of the AM to commit data. Something like below
```
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
  {
    super.processFormRequest(pageContext, webBean);
    OAApplicationModule am = pageContext.getApplicationModule(webBean);
 if (pageContext.getParameter("Save") != null)
    {
      OAViewObject vo = (OAViewObject)am.findViewObject("VO instance name");

      am.invokeMethod("apply");
}
}
```
AM method, you can check if there is a change or not as below apply now to
```
 public void apply()
  {
        if (getTransaction().isDirty())
      {
    getTransaction().commit();
      }
else
{
//Throw exception here
}
  }
```
Hope that I clarify for me.

Thank you

Throw an Exception object custom from a thread
I have to use my own Exception class. I want the Runnable.run () method throws an Exception.

I want to do something like this:
```
public void run(){
       throw new ControllerException("Warning: Plant Meltdown ");
```
This is the error I get when I try this:
Unhandled type ControlleException exception

Or something like this:
```
public void run() throws ControllerException{
```
This is the error I get when I try this:
Not compatible with Runnable.run)

How can I do this? I need to catch the error in a separate category.
You can't do that. You therefore have to restructure your application so that these exceptions can be handled somehow. Based on the description of your request you will keep (no description except that it is composed of more than one class) it is difficult to be precise, but in general I would look at something in the java.util.concurrent package. Perhaps something related to the class FutureTask might help?

Throw an Exception
Hello experts,

I need to validate the user's input and if it fails then throw an exception error.

I extended the controller, but I am not able to throw an exception because the original controller contains the following code:
If (oapagecontext. GetParameter ("Save"). = null)
* {oaapplicationmodule.invokeMethod ("copyPaymentTerm"); *}
oadbtransactionimpl.Commit ();
oapagecontext.putParameter ("confirmMessage", "AR_UPDATE_CONFIRM");
oapagecontext.setForwardURLToCurrentPage (null, false, null, (byte) 99);
*}*

Then when I hit Save it transfers to the same page using the statement oapagecontext.setForwardURLToCurrentPage (null, false, null, (byte) 99), so my extended controller never runs.

The extended controller has the following in the method of the PFR:
' Public Sub processFormRequest (OAPageContext oapagecontext, OAWebBean oawebbean)
{System.out.println ("Running extended controller processFormRequest");
Test string = "Hello";
If (test is "Hello")
{System.out.println("Hello...");
throw new OAException ("error: this is a test!", OAException.ERROR);
}
super.processFormRequest (oapagecontext, oawebbean);
}

Is there a way to get around this? I need to be able to throw the exception.

Thanks for your help in advance.
Hello

Instead of going through the personalization links, can you please click on the Page "Customize" in the upper right
and in the 'customize' page hierarchy, you should be able to see the PageLayoutRN
Then click on the pencil to customize, icon
Then you should be able to locate the standard controller.

Throw the exception of the app module
Hello
I use ADF 11.1.1.2 verison and my application is developed using the procedure (we use no BC)...
The approach I use is as follows-
1. create a procedure
2. create a module app and call the procedure of this app module.
3 - expose a customer interface and this method (data control) to see the data...

My question - when I create a method and expose it (visible sound in the customer interface), which allows you to create a table or any other component its works very well.
But according to my new req I have thrown an exception from this method in the case of any problem (let's say not able to update the db data)
When I throw the exception of the method available in module app method disappears and is not available to be exposed to the client.

Please let me know how we need to do something specific to raise exceptions in this case.

Thank you
Shubhangi
Subhangi,

Make sure you throw an exception which extends from local.

JDeveloper 10 g & ADF BC: AM, the editor can't see methods that throw the exception
I was curious to know why once I declare my throw on the method declaration clause, it does not appear on the window of the client interface of the editor of the AOS?

To work around this problem, I have to do the following:

1. in the MyAmImpl.java
+ ' public void methodA() {+
+ try {+
+ / / code that throws exceptions.
+} catch (Exception ex) {+
+}+
+}+

2 open the editor of AOS, expose the method on the client interface
3. return to the MyAmImpl.java and change metodA() to:

Public Sub methodA() throws Exception {}
a code that throws the exception
}
4. open the MyAm.java interface
change of the
Public Sub methodA()
TO
Public Sub methodA() bird exception

is this a bug?

Thank you
Wes
Try a local. It will work :)

Ideally local class sup for all your needs.

Thunderbird does not all files except "inbox." and against the info 'aid', there is NO 'account settings' under 'Tools' & I have the latest version of T.

Thunderbird does not all files except "inbox." and against the info 'aid', there is NO 'account settings' under 'Tools' & I have the latest version of T. I just need to download the SENT MESSAGES, Inbox not only.

Re: Where is 'account settings '.
If you do not see 'Tools', then you do not have your active 'Menu Bar'.
See picture below on the activation of all the toolbars make life easier.

Different methods of location of the 'account settings ':
Via the toolbar "Menu Bar":
- Tools > accounts settings
Through the pane of folders:
- Right-click on the name of the e-mail account in the folders pane, and then select "settings".
Via "Menu Icon.
- Menu icon > Options > account settings
Re: I need to download sent Messages Inbox not only.
E-mail accounts IMAP see a remote view of the files on the server.
You subscribe to view these folders in Thunderbird.
You synchronize directories subscribed for a copy in Thunderbird.
What you do in a folder for example imap: delete, will occur on the server, so viewing via webmail or Thunderbird folders appear identical.

However, in your case, it seems that you have created a POP e-mail account.
E-mail POP accounts can only connect to Inbox server and download server Inbox for the Thunderbird Inbox pop e-mail account.
It's not a quirk of Thunderbird; This is how all Pop mail represents the work.

There is a work around to get "sent" in the folder mail sent from server in Thunderbird. You just do it once, because when you send it through Thunderbird, it will put the e-mails in the folder sent TB pop mail account and not on the server.

Thunderbird creates a "Sent" folder when first send you an email.
So, if you have not yet sent an email, please send one, even if only to yourself.

Then, move all inbox emails in the appropriate folders.
You can create new folders to organize them.

How to create a new folder:
- Right-click on the name of the e-mail account, and then select "new folder."
- Give an appropriate file name and click "create a folder".
When the Inbox is empty:
- Logon to the Web e-mail account by using a browser.
- Move all emails "Sent" in the "Inbox".
In thunderbird:
- Click on 'Get the message'
all the "Sent" emails must get downloaded from the server Inbox anto your Inbox in Thunderbird.
- Then move all your emails in the 'Sent' Thunderbird folder.
You should now have all these emails downloaded from the server and display in Thunderbird.

Firefox will not load https pages. gives the security warning and will not accept an exception.

I had problems with Firefox and some sites for about a year, and it is located in my laptop. I have no problems when using my desktop at work or my dad's cell phone in his house. Some sites simply returns a page of text style; no html. Other sites give me a security certificate warning and FF will not accept an exception for this site, either by clicking the button or manually enter the site as an exception. Tonight, GOOGLE will not load again! Why, it's trying to load on an https server, I don't know, however. Several other sites have also begun does not not and are also trying to load it on a secure server.

Use Kaspersky, AVAST 2015, ESET, BitDefender or Microsoft family safety? These are among the most popular security programs which have a function to intercept your Internet connections and filter your traffic. When it's a secure site, in order to be able to decrypt and inspect your communications, the software must present a false certificate for Firefox. Sometimes, the software is not able to configure Firefox for this, or if you use the function of Reset of Firefox, the trust is broken and needs to be put in place again.

Unfortunately, the same symptoms can appear with some malicious software.

If you look at the second half of the post of Philipp, you see where you can check the section 'From' the certificate. This usually allows to identify the culprit. Can you take a look and report what you find?
