HANA and Data Services Job integration?

Hi.

Is it even possible to call a DS job from a HANA procedure?

We are having some problems trying to execute a job through a webservice, 'cause we are getting a cross-domain policy restriction.

In some documents that I have been reading, we can enable CROS in Tomcat 7.x, but we have DS 4.0 and it comes with Tomcat 6.x

Can you think in another workaround?

Thanks in advance.
