FilePoller Concurrent

[Peter Shen <pe...@powere2e.com>]

Hi ServiceMix users,


I'm a newbie, evaluating ServiceMix (3.3.1),
I developed a sample program,
which use a FilePoller to send EDI to JMS, and distribute it to a  
FileSender and database.

The xbean looks like:

   <file:poller service="esb:filePoller"
				endpoint="filePoller"
         targetService="esb:JMSProviderService"
         targetEndpoint="topicWriter"
         file="/home/xxx/EDI/C4/"
         archive ="/home/xxx/EDI/archive/"
         period="200" marshaler="#EDI2XMLMarshaler">
   </file:poller>

Well, it runs very well, when I put one file in the source folder,
but when I put 20 or more files once, then I got lots of errors and only  
very few files populated successfully.

The followings are the errors I got:

java.lang.NullPointerException
	at com.ctc.wstx.stax.WstxInputFactory.createSR(WstxInputFactory.java:751)
	at  
com.ctc.wstx.stax.WstxInputFactory.createXMLStreamReader(WstxInputFactory.java:341)

I searched the maillist and forum, it is a lock manager problem, isn't it?
or could you anyone give me some tips how I can solve it?

Thanks in advance.



Thanks and regards
