XNAT Gateway problem

[Simon Doran]

Misha,

Having set Gateway up with no problems for the XNAT instance running
on my local Mac, I am now trying to run XNAT Gateway on the Solaris
machine where our production XNAT server is.

There is no specific download for Solaris on your webpage, but I
figured that since it was Java, then the linux jars should work just
as well. I followed the linux instructions and the initial setup
screen popped up just fine. I filled in the parameters as follows:

Gateway settings
AE Title: XNAT_GATEWAY
Port: 4008

Default XNAT Server
Name: XNAT
Hostname: http://localhost
Username: admin
Password: xxxx

I got the error below when I clicked on "Apply".

The most significant part of the error seems to be:

Nested exception:
java.net.UnknownHostException: www.jboss.org

I have tried various other values for hostname, including the actual
IP address and the complete URL of the XNAT instance, both with and
without the 8080 port. If I wanted to access my XNAT webapp from the
same machine that I am running Gateway on, the required URL would be
http://localhost:8080/XNAT15.

Any ideas what I am doing wrong?

Could this be a firewall problem on port 4008?

Thanks,

Simon

Update:

I realised that a workaround for this problem was to run XNAT Gateway
locally on the Mac where OsiriX is. I tried this and I was able to use
the OsiriX "Query" and "Query Patient" options. Everything seemed to
work fine up until the point where I actually tried to download the
data. At that point the communication definitely happened, but OsiriX
gave me an error message "MoveDestinationUnknown" and the Gateway log,
correspondingly has:

Any suggestions?

OK. Sorted. Sorry to "debug on line".

Just a simple problem with my AE configuration. I hadn't realised it
would do all the listing even with this information incorrect.

However, I would still like to know why I can't set Gateway running
on the same server as the production XNAT instance.

Hi Simon,

Unfortunately, we don't have opportunity to directly support Gateway on Solaris, so your experience here will be pioneering. First thing you want to check is java -version on that machine, as the problem seems to be with enterprise beans. Sun Java 1.6 should theoretically work. Otherwise, I would suggest setting Gateway up on the same network, on a machine with supported OS variety (Linux would be your first choice, I presume).

I will try to look at the code that seems to be problematic, but no earlier than tomorrow.

Regards,
Misha

Thanks Misha. I'm at home today, looking after the kids - school is
out! - but will get back to this on Monday.

If Java version seems OK and you still have the issue, try replacing
the file <Gateway dir>/config/dcm4chee-qrscp-xmbean.xml with this one:
