TDB Error

Hello All,

I get this error when i try to reset TDB

com.hp.hpl.jena.tdb.transaction.TDBTransactionException: Can't expel: Active transactions for location: location:/ts/data/

        com.hp.hpl.jena.tdb.StoreConnection.expel(StoreConnection.java:198)
        com.hp.hpl.jena.tdb.StoreConnection.release(StoreConnection.java:188)
        com.hp.hpl.jena.tdb.sys.TDBMaker.releaseLocation(TDBMaker.java:62)

there are no active connections from the application

what am i doing wrong?

Thanks
Kamalraj

Kamalraj,

This, and the companion email, aren't enough to reproduce the situation. 
  The fact it is inside tomcat/jersey might be a factor.

Most likely is that there is active transaction. Read transactions end 
when .commit(), .abort() or .end() is called; write transactions need 
.commit(), .abort() (calling directly .end() will force an abort). 
These need to be called even if the query has a exception or finishes 
normally.

Hello Andy,

These are the details

Java Version :- 1.7.0_72

TDB version :-  1.0.1

Jena Version :- 2.12.0

Running on : -Ubuntu Linux

Application server :-  tomcat

The application we created is something similar to fuse, it has TDB wrapped with a rest service and has other management functionalities like backing up of software metrics etc..

there are no active connections from the application

what am i doing wrong?

It not possible to tell from what you've said.  There isn't a common reason why this might happen.

Do you have a complete, minimal example?
Did anything happen earlier like an exception?

Does it happen always or occasionally?

What version of Jena is this?
What operation system are you running on?
What version of java? Which JDK?

Thanks
