To store JSON data, I installed the NuGet package sqlite-net-pcl for the Xamarin project. Before install the package sqlite-net-pcl, everything is working normally and I didn't change the contents of code. No ideas what wrong with the setting. Please comment how to solve the problem?
Installed the NuGet package sqlite-net-pcl and execute Serialize, an exception is raised.
execute to serialize an object to JSON,
// route is an object
JsonSerializer.Serialize(route);
and exception is raised unexpectedly.
catch (Exception)
{
// exception
}
A .net application works at a server which SQL Server 2005 , now we relocate the application to the new server which is SQL Server 2008.

You will need to configure Reporting Services on your new SQL Server if it's not configured.
You've probably done that.
Inside the error, we have:
[MissingEndpointException: The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version. ]
Next make sure that your application is pointed at the new instance of SQL Server (it was looking for a 2005 instance). And then check that your application will work with SSRS 2008.
Handler processing failed; nested exception is java.lang.NoSuchMethodError: org.springframework.web.util.WebUtils.getNativeRequest(Ljavax/servlet/ServletRequest;Ljava/lang/Class;)Ljava/lang/Object; I am getting this error after submitting form
It looks like you have class WebUtils from Spring 2.5.x branch (this method has been added in 3.x branch).
Please check your dependencies and search for mixing of libraries from 3.x and 2.5.x branch.
Im implementing a rest api with sinatra and jruby. The application domain is implemented in java. I have not figured out how to catch all exceptions thrown by the java layer in Sinatra. the global 'error do ... end' does not catch my java exception.
Any hints would be appreciated

I have a block like so:
begin
# some SQL request
rescue Mysql::Error => e
logputs "Mysql::Error occurred, retrying in 10s: #{e.message}"
sleep 10
retry
end
But when a "Lost connection to MySQL server" error occurred, this block was not able to catch it and retry (the MySQL server was restarted). Any idea how I can properly catch this exception?
Thanks!
From your comment it looks like what's happening is that a Mysql::Error exception is being thrown, but then caught by ActiveRecord which then throws an ActiveRecord::StatementInvalid exception (which isn't very helpful behaviour in this case!).
I'd say change your rescue to catch the AR::StatementInvalid exception and see what that does for you.
Are you sure you are rescuing the correct type of exception?
Try using the following code:
rescue StandardError => e
puts e
That should output any exception that is raised and more importantly you will be able to see the specific type. Then you can adjust your rescue statement to be more specific.
