Hi Tino.

I have installed the beta of Opennebula 2.0 and tested the OCCI-Server again.
It seems the issue still exists. I have tried different programs (my java client, curl and occi-storage) with different options. 
 
The good news: occi-storage command still works fine! (-:
(occi-storage create xmlConfiguration.xml)


The bad: the others doing not so good:

The occi-server is up and running. I have added a ttylinux to the image repository (via oneimage) and printed out the occi-server-representation:
	$curl -u oneadmin:[sha1-password] http://virtualbox.one.de:4567/storage
	<STORAGE COLLECTION>
		<STORAGE href=http://virtualbox.one.de:4567/storage/0 name="testfile_ttyLinux"/>
	</STORAGE_COLLECTION>	


Afterwards it failed to add some more files to the storage-endpoint via occi:
	$occi-storage -M create xmlConfiguration.xml
	#<Net::HTTPInternalServerError 500 Internal Server Error readbody=true>
	[ImageAllocate] Error trying to CREATE IMAGE Returned error code [-1].
	$cat occi-server.log
	(...)
	127.0.0.1 - - [10/Sep/2010 12:18:24] "POST /storage HTTP/1.1" 500 70 0.5345
	

	$curl -u oneadmin:[sha1-password] -F occixml=@/tmp/xmlConfiguration.xml -F file=@/tmp/ttylinux.img http://virtualbox.one.de:4567/storage -o one2_curlA.html

	
	$curl -u oneadmin:[sha1-password] -F occixml=</tmp/xmlConfiguration.xml -F file=@/tmp/ttylinux.img http://virtualbox.one.de:4567/storage -o one2_curlB.html
	$cat one2_curlB.html
	Wrong type!



Any ideas? Do I have to change any content-types for the multipart post-request? Should I try different options? What would you suggest?
Please let me know If you need more log-files..



Thanks
Marco

Hi Marco,

We have greatly improved the code of the OCCI server in the latest
v2.0 release.

Would you mind trying this out to see if the problem appears more clearly in the logs?

Regards,

-Tino
