When I try to get data from dynamoDb I am getting exception Resource Not Found exception. It is not going inside catch block as well so that I can catch the exception. Due to this I am getting runtime error. How to handle this error?
this.getModel()
.query(queryfilter)
.attributes(attr)
.exec();
}

how to handle an exception thrown from within outer catch block in bpel1.1.
I tried to publish a queue 'Q1' from bpel but i got an exception while accessing it.
Exception got handled in fault policy from where it was re thrown and got handled in a catch block. For some reason we are publishing the same queue 'Q1' again. and again we got the exception. So how can i handle that exception. Please throw some light.
There are many ways how to handle error exception in bpel.
Oracle has provided AIA framwork for BPEL message flow and error handling.
if you are using it then it has predefined templates and you have to just migrate in your code.
also for your specific scenario all catch block will help.
While cherrypicking changes from gerrit, JGit often throws the exception Remote does not have refs/changes/xx/xxxxx avaialble for fetch exception
This seems to be intermittent. After few retires, the error does not appear. Does anybody know why this exception occurs?
I was following the SignalR documentation on Github to message a group. I join just fine with:
Groups.Add(Context.ConnectionId, "foo");
But then when I try and send a message to all the users in that group with:
Clients.Group("foo").syncShortList(id);
I get an exception. I know there's nothing wrong with 'id'. The code will never continue after this line, so I set the debugger to catch all thrown exceptions, and found out that the second line throws the exception:
'Microsoft.AspNet.SignalR.Hubs.GroupProxy' does not contain a definition for 'syncShortList'
I know for sure that I'm listening for the event in javascript:
funnelHub.client.syncShortList = function (id) {
console.log("syncing");
console.log(id);
}
The event is never getting fired. Does anyone see where I'm going wrong with this? I'm running SignalR 1.0.1
As discussed in https://jabbr.net/#/rooms/signalr the error is a First Chance Runtime Binder exception that happens on the first invoke on the group dynamic object. In the end it's harmless.
I am using a filereference Object to export an excel file from my flex application. I am using fileReference.save() from Flash player 10. I am getting an error if the file i am trying to save is already open. This error is not getting handled even if i put a try catch block. I have tried adding a listener with IOErrorEvent.IO_ERROR. Still the error is happening. This is the Error message i am getting - "Error #2044: Unhandled IOErrorEvent:. text=Error #2038: File I/O Error."
Thanks in advance.

This is asynchronous error, you can't catch it with try-catch block. Add an event listener for IOErrorEvent event.
Also, we need some details to get the source of the problem.
I'd like to get the message number and severity level information from SQL Server upon execution of an erroneous query.
For example, when a user attempts to delete a row being referenced by another record, and the cascade relationship is "no action", I'd like the application to be able to check for error message 547 ("The DELETE statement conflicted with the REFERENCE constraint...") and return a user friendly and localized message to the user.
When running such a query directly on SQL Server, the following message is printed:
Msg 547, Level 16, State 0, Line 1
<Error message...>
In an Asp.Net app is this information available in an event handler parameter or elsewhere?
Also, I don't suppose anyone knows where I can find a definitive reference of SQL Server message numbers?
Sure - check out the SqlException that gets thrown is something goes wrong on SQL Server.
It contains a collection of SqlError elements, which contain a bunch of properties, including
Class Gets the severity level of the error returned from SQL Server.
LineNumber Gets the line number within the Transact-SQL command batch or stored procedure that contains the error.
Message Gets the text describing the error.
Number Gets a number that identifies the type of error.
Procedure Gets the name of the stored procedure or remote procedure call (RPC) that generated the error.
Server Gets the name of the instance of SQL Server that generated the error.
Source Gets the name of the provider that generated the error.
State Gets a numeric error code from SQL Server that represents an error, warning or "no data found" message.
try this to see what all the messages are
SELECT *
FROM master.dbo.sysmessages
SQL Server error messages are located in master.dbo.sysmessages
In ASP.NET if you catch the Exception as a SQLException then the error number and message will be available.
I think it is good practice to iterate through the SQL errors as there may be more than one
(untested)
try
{
// Do some stuff here
}
catch (SQLException sqlex)
{
foreach (SqlError error in sqlex.Errors)
{
Console.WriteLine(error.Number.ToString());
Console.WriteLine(error.Message.ToString());
}
}
catch (Exception ex)
{
}
