error occured while running the query

The Instant JChem project we're testing raise an error as soon as we are querying a structure
The details looks like:

org.springframework.transaction.TransactionSystemException: Could not commit JDBC transaction; nested exception is java.sql.SQLException: Getrennte Verbindung
 at org.springframework.jdbc.datasource.DataSourceTransactionManager.doCommit(DataSourceTransactionManager.java:270)
....

If we query strings - no problem.

We're using Instant Jchem 6.0.2  (Windows 7) and Instant JChem 6.0. (Windows XP)
and Jchem Cartridge  with
Java VM vendor: Sun Microsystems Inc.
Java version: 1.6.0_38
Java VM version: 20.13-b02
JChem version: 5.12.0
JChem Index version: 5120000
JDBC driver version: 11.1.0.7.0-Production

The problem raise on both environments.

What can be the reason?

Hi, the problem can be either in JChem Cartridge on the server or in the connection to that server. I can not tell you more without IJC log file. If you don't want to attach it here, could you please send it to my email fzimandl(at)chemaxon.com ?
Information about the log file can be found at http://www.chemaxon.com/instantjchem/ijc_latest/docs/admin/debug_info.html#logfile.

Did this problem raise after the IJC upgrade or is it there since the beginning?

The problem is there since the beginning and is the case for IJC 6.0 (XP environment) and IJC 6.0.2 (Windows 7)

I've sent you an eMail with the logfile

Follow up in the email. I just sent...
