BackingStoreException at startup

Options
alokreturns
alokreturns Explorer
in RFA

Hi Team,

While starting the application which connects to Reuters services, in my case dIDN_RDF. We could see the below error but the application continue to receive and process the updates :

ERROR [stderr] (ReutersNamespace::ReutersConsumerSession Session EventQueueGroup) BackingStoreException during checkForLink for path: /com/reuters/rfa/_System

Please can you suggest what's the meaning of error and how we can avoid this ?

Thanks in advance !!

    Further to this:

    If you dream of avoiding Java Preferences (with all its weird quirks of using Windows Registry , hidden files and what not) and instead just want to have a old-school config file next to your application, but you do not have access to the source code of the application or for whatver reason do not want to mess with it ... then what ??

    Answer:

    Just add Preferences2Go to your application's startup. It was created for this exact purpose. The change is completely transparent to your application and to the RFA Library.

    It is really an error from the Java Preferences sub-system, not from RFA itself. Just google BackingStoreException and Java Preferences. I find that Java Preferences is one of the less intelligent things in Java. It is a fine API but the implementation on Windows - which is to use the Win Registry - just throws most Java devs off. Luckily you can use your own Java Preferences implementation instead of the default one (and this would be completely transparent to the RFA lib) or you could avoid using Java Preferences altogether by using ConfigDb in RFAJ.

    You error is likely caused by lack of access to the relevant node in Java Preferences which on Windows would translate into lack of access to the relevant key in the Win Registry.

    Unless you really dig Java Preferences - and are familiar with its quircks - I suggest to avoid it.

    Best of luck

    Hi @alokreturns,

    Try to run your application using an admin account first, then re-run it in normal user account. That should fix your problem.

    Regards,
