Unable to run qsac-standalone-0.4.jar on win7
Arman
I am trying to run the standalone version on win7 but unfortuneatly it
gives me an error.
How to overcome this problem?

Thanks for reporting this.

It looks as if there's some inconsistency, or confusion, between different escaping contexts. I haven't tested qsac on Windows before, so... thank you!
I've found a location for the problem, I think, but I'm not _completely_ sure what the problem is in detail. Can I ask you to try again with the jar file at <http://nxg.me.uk/temp/qsac-standalone-r501.jar>?
You should get the same result, but this time with a little more logging, which might explain things.
Best wishes,
Norman

Thanks for this -- I'll study this and see if I can work out how to fix this.
I made no functional changes to this version -- only added a little more output to confirm where things were going wrong.

Ah, but the thing is that I'm carefully not using "c:\\temp\\" for anything, but relying on Java's get-me-a-temp-path functionality.
The problem (as I rather suspected, but as this confirms) comes about because this temporary directory ends up being constructed as "C:\temp\qsac-persistence", which is then parsed by something else, which (somewhat unexpectedly to me) regards the backslashes as escapes, in context. The "\t" is OK, but it's the "\q" that produces a 'lexical error'.
Hmm: simply escaping the backslashes seems a bit kludgy to me. But...
I probably won't have much time for this this week, but I hope to get back to you next week. Shout, if I haven't.

Do you have some web site with skua. I would like to see how it works and what one can do with that?
Thanks
Arman.

But a moment's more reflection convinces me that I'm being nuts -- this is obviously the correct thing to do. Try <http://nxg.me.uk/temp/qsac-standalone-r508.jar>. That works for me, but I can't test it on windows, so you get to do the honours!

Once you finally get the thing running, then <http://localhost:8080/tutorial.html> should lead you through doing some interesting things with it.

That's something, at least!

OK, that's a bit deeper down. I can't spot what's going wrong here (I don't _think_ it's the same problem), so I think I'll have to find myself a windows box somewhere, and do some digging.
All the best,

I think I've found the problem (actually two, only one of which was my fault!).
Can you try <http://www.astro.gla.ac.uk/users/norman/temp/qsac-standalone-r509.jar>. That should run on Windows (and does run, on the one Windows XP machine I've got access to).
If so, I'll release this as qsac 0.4.1.
Thanks for the report, and your help tracking things down. Best wishes,

I'm not sure I follow you. If you cut and paste the examples on the tutorial page, at a shell prompt, that should work through the various bits of functionality. How would the script you envisage add to this?
All the best,
