java.lang.NullPointerException: name can't be null (similar to JCR-1272 issue)

Hi all,

I am using jackrabbit 1.4 as my content repository and the underlying 
database is derby.
I am using jackrabbit-jca-1.4.rar connector to connect to respository 
from my web-app.

I am trying to store a file as one of the property of a node and then 
retrieving it.
The problem is the property is being created but I am getting an 
exception while retrieving the property.
Strangely when I restart my appserver where the jackrabbit-jca is 
deployed, I will be able to get the property without any exception being 
thrown.
It may not be completely reproducible but definitely in my case it is 
failing most of the time.

I think this is similar to the bug : 
http://www.mail-archive.com/dev@jackrabbit.apache.org/msg09384.html

Any ideas why this is failing??

Regards,
Prakash

Hi all,

Setting the system property "org.jackrabbit.useDataStore" to "false" before starting the repository seems to solve this issue.

Thanks to Thomas Mueller for the solution. :-) 

Cheers,
Prakash

what i can tell from your stack trace, retrieving the the value from your newly
created property seems to return a BLOBInTempFile instance which had been
already discarded (the 'file' field is set to null which causes the subsequent
NullPointerException).

please create a jira issue and include all relevant information
(repository,xml etc).
it would help a lot if you could attach a simple test case for
reproducing the issue.

BTW: i don't think that  this issue is related to
http://issues.apache.org/jira/browse/JCR-1272.

thanks!
stefan
