Dear JOpera support,
how is the peristence of instances/tasks configured with JOpera server to maintain the state
beyond server shutdown ? This is esp. needed to recover long running (human) tasks.
Chapter 7 (FAQ) mentions such an option without providing any details:
"If you have configured the kernel to use persistent storage, this information
may even survive kernel crashes."

Many thanks

We have a Linux-based HPC cluster and using SGE to manage jobs. We will be constructing workflows that link command-line applications. What is the best way to use JOpera in this setup? Does JOpera has any special adapters for handling jobs submitted through 'qsub' command in SGE ?

Thanks

New Features:

• JS Adapter (embed JavaScript snippets into your processes - requires Java6)

Fixes:

• HTTP Adapter: urlstring parameters no longer escaped by default
• XPath Adapter: results can now contain element tags (thanks to Rodrigo Marques Pupe)
• Important kernel livelock on multicores fixed (by Achille Peternier and Daniele Bonetta)

Download the updated mashup_doodlemap.oml example that ships with JOpera fixed to work with the latest version of the Doodle RESTful API.

hi,

We are trying out JOpera to orchestrate RESTFul service.

It seems that % used by JOpera to delimit variables is having conflict
with another package for HTTP GET request, as % is a commonly used escape
character in HTTP protocol.

Am wondering whether there is any place we could change the % to some
other characters?

Your help would be greatly appreciated.

Hi,

I've been a couple of days learning how to use jOpera using its examples and manual but I had a problem with the ones using web services. I can import an WSDL without any problem, but I can't find the WSIF component that is listed in the manual and is a dependence in web services related demos .

I have installed jOpera latest version together with Eclipse Helios 3.6.1, and the file ch.ethz.jopera.subsystems.ws_2.4.6.jar is present in the plugins folder, but there is no oml file modeling the adapter.

Please can anyone help me in running those demos??

Thanks in advance.
