JobId and default user credentials in 52 North 4.0 Beta Version

[gabrilator]

Hi, I installed the 52 N server 4.0 Beta Version in order to be able to use the new methods provided in WPS 2.0 such as getStatus, but I can't log into the server (I guess this is needed in order to check the current JobIds).

Could anybody provide me some insights on this ?

Thank you!

Hi, the default credentials for the WPS are wps:wps. But you will not be able to see any JobIDs after login. You get a JobID after sending an execute-request. However, in our new WPS framework (javaPS) we list the jobIDs in the Capabilities document, see here: http://geoprocessing.demo.52north.org:8080/javaps/service?request=GetCapabilities&service=WPS

Thank you bpross-52n, I didn't know about javaPS! So then, would you recommend that I disregard 52N 4.0 Beta and just jump to javaPS?

Cheers!

Currently, when I send an execute request, I'm not seeing the JobId back. I'm just seeing a blank response and then I do see the result of the execution of my algorithm. Where should I be able to see it?

Thank you!

You probably executed synchronously. To execute asynchronously (and to be able to get status updates), set the attribute "mode" to "async" in your request. Below is an example.

As for the question WPS 4.0 vs. javaPS: Main differences:

• WPS 4.0 has an admin-UI, javaPS not (yet)
• WPS 4.0 supports the WPS standards 1 and 2, javaPS only 2
• WPS 4.0 comes with processes, javaPS is shipped without any processes
• WPS 4.0 uses xmlbeans, javaPS supports streaming XML readers/writers

In general, WPS 4.0 is a grown project with many features, but also legacy code. javaPS was build completely from scratch. It is pretty bare-bone atm., but new features will be added step by step. We are using javaPS in all of our current projects
