Throwing Exceptions from CacheStore

If I encounter an exception whilst persisting a cache's contents via a CacheStore implementation, how can I pass this expection up to the code that put the entry on the cache? If it doesn't make it into the database, I'd like to throw something to let the client code know.

Hi Mike,
Rethrowing synchronous CacheStore exceptions to the calling thread is now supported in Coherence 3.0. To do so, set the <tt>rollback-cachestore-failures</tt> configuration element in your <tt>read-write-backing-map-scheme</tt> or <tt>versioned-backing-map-scheme</tt> caching scheme to true.

Throw exceptions from threads?

Is it possible to throw exceptions from threads since I can't add the throws statement to the run method I don't know how I could do it...
Any help greatly appriciated!

CyaYou can't throw checked exceptions, because obviously the code responsible for invoking the run() method wouldn't know what to do with it, and you wouldn't be the one to catch them. You can however throw unchecked exceptions (such as those based on RuntimeException).

How to throws exception from subprocess?

Hi,
I use subprocess in my process and I need throws exception from subprocess to my main process.
Thanks for help.
Jakub

The only to throw an exception from a sub process is by leveraging the Exception event (from the event view).
You need to throw the exception, by dragging the Exception event and choose Throw into your subprocess. Then you need to add an exception "catcher" in the parent process to catch the Exception.

I can throw exception from a catch

Hello,
I have created a new Exception : myException (for example).
and, i can't throw it under a catch bloc !!
My code :
public myMethod( ... ) throw myException {
     try {
          if(true) thorw new NullPointerException("test nll pt");
     } catch(NullPointerException nullPt) {
          if(true) throw new myException("toto",nullPt.getMessage());
this code doesn't want to throw "myException" from the "catch" !
Why ?
myException extends the class Exception.
Thanks.
maxx.

First, I assume you didn't cut and paste the code, as what you have there won't compile. Can you 1) paste the actual code and 2) be a bit more specific about what's happening?
Aside from a couple of misspellings, I don't see why it wouldn't throw myException. Is it not compiling? Running but not throwing any exception? Throwing a different exception?

Throwing exceptions from Java Stored Procs

Hi,
We'd like to be able to define our own exceptions from our Java Stored Procedures (i'm going to call them JSP's even thought that's not PC). I am aware that the manual says "When a Java stored procedure executes a SQL statement, any exception thrown is materialized to the procedure as a subclass of java.sql.SQLexception. That class has the methods getErrorCode() and getMessage(), which return the Oracle error code and message, respectively."
Does this mean that we can't really extend the SQLException class and define our own set of methods for handling exceptions in JSP's? Is there a work around for handling exceptions in JSP's? Since exception handling is such a powerful component of Java, I figure someone has addressed the limitations of the above paragraph.
Thanks,

Unfortunately, right now GCC's standard C++ runtime library is NOT threadsafe. You can find documentation supporting this on the GCC website. Since you're running a multithreaded Java/JNI application, you'll certainly hit this shortcoming.
<p>
Supposedly, this will all be fixed in GCC 3.0.
<p>
In the meantime, if you're using SPARC, the only option you have is either using SC4.2 or Forte 6 Update 2 (this particular version is VERY important for several reasons).

IViews throwing exception from Non Admin Login?

Hi,
I have created some iViews using .Net PDK for SAP.
I have added these iViews to a page. Then the page is added to workset. I have created a new role and assigned this workset to the new Role. Then I have created a new User and associated this user with the newly created Role.
Now the problem is whenever I login to portal using new user name and password I am able to see the workset as well as page and iViews. But these iViews are throwing following exception.
An Error occurred while processing one of the iViews on this page in the .NET server.
More information:
1. Default Trace
Exception id: 10:37_04/10/05_0037_6409650
However these iViews are running properly when I preview them from admin login.
What are possible causes/solutions for the above mentioned behavior?
Thanks for suggestions
Regards,
Vikas Khandpur

Hi Vikas
You should use the Permission Editor to assign user, group and role permissions to portal objects.
You can launch the Permission Editor in two ways:
1. Using the central Permission Editor
a. Choose System Administration ® Permissions.
b. Locate the folder or object you want to assign or edit permissions for, right-click it and choose Open ® Permissions from the context menu.
2. Using the object-specific Permission Editor
a. Launch the relevant administration tool or editor in the portal.
b. In the Portal Catalog, locate the object or folder to want to set or edit permissions for. Then, do one of the following:
i. Right-click the object and choose Open ® Permissions from the context menu.
ii. Open the object in the editor, and from the Display menu or drop-down list, choose Permissions.
To know how to set permissions in the permission editor, please refer to the following thread.
http://help.sap.com/saphelp_nw04/helpdata/en/f6/2604db05fd11d7b84200047582c9f7/content.htm
As for your doubt on why you are able to view the iViews from an administrator's login,it is because The standard super administer role is assigned maximum access to the entire set of portal initial content. The Super Administrator role is assigned by default to the Administrators group. Therefore, initially all standard administrator users have super administrator permissions in the portal.
Hope that helped.
Best Regards

Throwing Exceptions from a new Thread

Please help if you can.........
I have a very simple RMI server, that is used to run processes in seperate threads on a server machine, that are kicked off by a client GUI.
All works fine, except if the process can not be found, then the server generates an IOException. How can I get the thread to throw the exception back to the RMI Server, and then back to the GUI.
I have tried to throw Runtime Exceptions but that did not work, and I can not declare the run method of the thread to throw a remote exception......
Any help would be most appriciated...

How to throw exception from Listener's Event Methods

Hi,
We are using Jdev 10.1.3 and I'm implementing a class that implements EntityListener and RowSetListener interfaces.
The problem that i'm facing is when I override the event methods of the interface (Which don,t throw any exception) , I'm not able to throw any exceptions in overridden methods also. Kidnly guide me on how to achieve this...
Sample Code :
public class GenericHistoryViewObjectImpl extends ViewObjectImpl implements RowSetListener
// this event is fired when a row is deleted from rowset and it registers data in history
public void rowDeleted(DeleteEvent event)
latestEvent = "DEL";
try
GenericHistoryManager.registerDataInHistory(this);
wasLastEventExecutedSuccessfully = 1;
catch (Exception e)
e.printStackTrace();
wasLastEventExecutedSuccessfully = 0;
genericHistViewException = e;
from The mothod public void rowDeleted(DeleteEvent event) of RowSetListener i want to throw an exception ...

JSalonen is totally correct. I would only add that this topic, generally, exposes the differences between checked and unchecked exceptions. Unchecked exceptions extend RuntimeException or Error. Checked exceptions extend Throwable or Exception. There are important differences.
Checked exceptions must specifically be caught or declared in a throws clause of a caller. Unchecked exceptions do not have this restriction. This means you can always 'wrap' (or throw without wrapping) an unchecked exception. Unchecked exceptions are very useful. You can use an existing unchecked exception, or create your own by extending RuntimeException or Error.
To illustrate the difference, let's say we are creating a new user account and storing it in the database. For a checked exception, I might define DuplicateUserRegistration in case a user registers with an existing user name (a non-fatal error case that can be anticipated in system design). However, if the database was down, I would not throw SQLException (which is checked) but rather something like ResourceUnavailableError. This would be unchecked. A calling class (normally) will not be able to realistically handle a situation where the database is down, so why force that caller to either declare throws SQLException or catch SQLException for this instance?

Hey there, and apologies for the lack of response. Are you still having this issue and still needing help? If so can you tell me a little more. Where is the application running (web/worker rolls)? what are the details on the SQL Database?

Cannot throw exception from switch-"unreachable statement"

Hi,
why is this an unreachable statement?
public static Msg newMsg(int type, Object data)
      Msg msg;
      switch (type)
          case MsgTypes.MSG_CLUSTER_CREATED:
              msg=new MsgClusterCreated(); break;
          case MsgTypes.MSG_REPLY:
              msg=new MsgReply(); break;
          default:
              throw new MessageTypeNotDeclaredException(); break;     //unreachable statement!!!
      msg.setDataSegment(data);
      return msg;
}

When you throw an exception, the program flow never continues "normally" on the next line --- control is always transferred to the nearest exception handler. Thus control never reaches the break statement on the same line, and "unreachable statements" like this are illegal in Java.
Solution: remove the unnecessary "break;"

Throws Exception

Dear Expert,
May I know how to throw Exception from a thread back to calling program ?
As I always get the following message when compiling the code
cannot override run() in java.lang.Thread; overridden method does not throw java.lang.Exception public void run() throws Exception
Thanks!

From what I can see in the javadoc, you can create a subclass of ThreadGroup and override its uncaughtException method, then you'd have to create a Thread that belongs to an instance of your ThreadGroup subclass and have its overridden method set some variable in your main thread. However you should recognize that whatever started your thread may not even exist when it throws that exception, and it may not be sitting around waiting for your thread to throw an exception. You should reconsider that requirement carefully before actually trying to implement it.

Custom Indirection Container throwing exception in constructor

Hi I've following the how-to and implemented my own custom indirection container. However, when reading an object from the database I'm getting the following exception. I'm guessing that it could be related to having null references stored as 0 in id columns. Any help would be greatly appreciated.

Clients of your class might not like you throwing
exceptions from the ctor. If they're checked
exceptions it'll mean try/catch blocks. If there are
LOTS of checked exceptions that'll mean lots of catch
blocks. Could get messy fast. You could catch in the
ctor and wrap in a subclass of
java.lang.RuntimeException. Those are unchecked, like
java.lang.IllegalArgumentException.I would strongly advise against making your checked exceptions unchecked just so that the caller's code will compile without try/catch blocks. Either way--checked or unchecked--if I do Foo foo = new Foo();
foo.doStuff(); I won't get to doStuff() if the ctor threw an exception.
You'd throw unchecked exceptions in those cases where it's appropriate--e.g., the caller passed you invalid args (bad code on the caller's part, appropriated for unchecked exception), or the VM couldn't get enough memory to create your object (probably not something the caller can do anything about, so, again, appropriate for unchecked).
But if, for example, he's passing you database login parameters that an end user provided, and the password is wrong or the host is unreachable, then you'd want to throw a checked exception, because it's not bad code on the caller's part, and there might be something he can do to recover.
Note that the example of the incorrect password above is quite different from the "invalid args" example in the previous paragraph. Your method would throw IllegalArgumentException if the caller passed args that violate your method's precondition--e..g. lie outside some range of numbers. That is, it's a value that your method simply can't use. A bad password for a db login, on the other hand, is legal as far as your method is concerned, it just failed authentication in the db.
@%: I know you're aware of the proper use of checked/unchecked exceptions, but the way you worded you post kind of sounded like you were saying, "just use unchecked if you find the caller has too many try statements."

Exporting methods that throw exceptions?

Using 10g Preview, I have encountered the following situation:
I've written a custom method in my ViewRowImpl class that I intend to export as a client row method. It's a public void method that takes a single String parameter.
Originally, I declared that the method throws Exception. With the throws clause present, the View Object wizard does not display the method in the list of available methods to export to the client. Removing the throws clause causes the method to appear in the list.
There's nothing in the documentation that I can find to explain this apparent restriction. The closest thing I can find has to do with all types in the signature being Serializable. Nothing is mentioned about exceptions.
Can somebody explain why methods that declare thrown exceptions can't be exported to the client? Or does the type of exception declared need to be narrower, such as a JboException?

I wondered the same thing. Take a look at this thread:
Why can't I throw exception from the Impl?

WebService throw Exception

I am trying to test throwing exceptions from a java web service.
     * Web service operation
    @WebMethod(operationName = "newRole")
    public String newRole(@WebParam(name = "name") String name, @WebParam(name = "users") String users) throws Exception
        throw new Exception("TestException");
    }Now whenever I test this webservice I get:
"Service invocation threw an exception with message : null; Refer to the server log for more details"
"Exceptions details : java.lang.reflect.InvocationTargetException ..."
The stack trace is massive.
Now if I examine the log I see the regular normal "Exception: TestException" message.
How can I get the web service to properly convert the Exception into a proper SOAP message not wrapped up on this InvocationTargetException .
Thanks,
Stephen

Using sql bulk copy throwing exception -The given value of type String from the data source cannot be converted to type int of the specified target column

Hi All,
I am reading notepads files and inserting data in sql tables from the notepad-
while performing sql bulk copy on this line it throws exception - "bulkcopy.WriteToServer(dt); -"data type related(mentioned in subject )".

SqlBulkCopy bulkcopy = new SqlBulkCopy(conn);
bulkcopy.DestinationTableName = dt.TableName;
bulkcopy.WriteToServer(dt);
conn.Close();
Issue 1:-
I am reading notepad: getting all column and values in my data table now while inserting for date and time or integer field i need to do explicit conversion how to write for specific column before bulkcopy.WriteToServer(dt);
Issue 2:- Notepad does not contains all columns nor in specific sequence in that case i can add few column ehich i am doing now but the issue is now data table will add my columns + notepad columns and while inserting how to assign in perticular colums?
sudhanshu sharma Do good and cast it into river :)

Hi,
I think you'll have to do an explicit column mapping if they are not in exact sequence in both source and destination.
Have a look at this link:
https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlbulkcopycolumnmapping(v=vs.110).aspx
Good Luck!
