Thanks, Tom There are no open issues with getList() and FileChangedReloadingStrategy I am aware of. At first I would like to ask you to update to Commons Configuration 1.5, which has been released recently. Don't know whether this will help, but just in case. If the problem persists, I need some more information to reproduce it: - A code fragment demonstrating how you access the configuration. - A fragment of the configuration file with the properties you try to access. - In which way is the configuration file changed on disk? Was the key you try to access just added? - What happens if you pass the key you use for getList() into getString() or some other method? (In this case the first element of the list should be returned.) - Does getList() work after getString() was called?

This thread, which looks like it is waiting for a response from the database, has got the lock on the connection pool that is blocking all of your other db related threads. A quick Google doesn't shed a huge amount of light on the issue. The following were mentioned as possible causes: - tablespace full - one connection editing a row, not committing and another connection trying to edit the same row Neither of these seem to be relevant to not being able to create a connection. I would take a look at the database to see why this thread appears to be taking so long to be creating a new connection.

where can i find procrun
Hello, mybe i'm stupid or i'm blind but i can't find a download for the procrun.exe. or am i running the wrong version of windows which doesen't contain procrun? (I'm running Windows Server 2003R2) This page http://jakarta.apache.org/commons/daemon/procrun.html talks about the usage of procrun (no Download here). And on the page http://jakarta.apache.org/commons/daemon/binaries.html in the chapter "What to do to get the excutable (typo in the page!!)" this is the only information i get there: The procrun.exe has to be installed as a service. (See procrun for more information. I like this backlinking seems like i'm stuck in an endless loop. Isn't this odd for you too? On the binaries page http://www.apache.org/dist/commons/daemon/binaries/ there is no distribution for Windows! It shouldn't be so hard to provide a little "How to get started" instruction for newbees like me! btw: after googleing i found nothing to download! Hell this can't be so complex! Do i have to compile this thing for myself, but how?

[Configuration] getList returns an empty list if the underlying configuration file is touched
Hi, I'm running into a problem in which the getList operation returns an empty List if and when the underlying configuration file is updated (I am leveraging the FileChangedReloadingStrategy). I am using Commons Configuration 1.4 with the DefaultConfigurationBuilder in conjunction with the XPathExpressionEngine. Please note, other operations, getString for example, work fine. Here's an excerpt from my configuration.xml file ... So, with that said, are there known issues with the 1.4 implementation of the FileChangedReloadingStrategy and/or the getList operation that would explain this behavior? Thanks, Tom PS.
