java.lang.ClassCastException: com.rapidminer.operator.web.io.MultiThreadedCookieManager cannot cast

Samir · July 2020

Hello, I am quite new to RM server and when running the process as Web service I get the following error:

java.lang.ClassCastException: com.rapidminer.operator.web.io.MultiThreadedCookieManager cannot be cast to com.rapidminer.operator.web.io.MultiThreadedCookieManager

I have used Get Page Operator and JSON to XML in the Process which I thought has something to do with this.

It works normally but does not work as Web service.

Server Log:

This issue is really hard to track down as it's working on our end, so because of this we think that it could be setup related or that classes/extensions are loaded more than once and thus the casting is broken.

Would it be possible to setup an instance on a separate machine, starting from scratch and just with the rmx_web and dependent extensions so we can rule out that the setup is causing this?

Hi. How does your process look like? When I am trying to reproduce with a simple Get Page and JSON to XML I am not able to reproduce your error in a web service. Could you try to run the attached process and see if succeeds on your end?

Samir · July 2020

@aschaferdiek

I got the same error when I ran your process too.

Here is my process.

Also can this have something to do with that, I run Job Agent manually?

aschaferdiek · July 2020

Just to be sure: the process I've attached also fails in a web service? And it also doesn't run in normal Job Agent?

I quickly verified again, the simple example works for central repository, webservice and projects here. When only running the Sub Process in your attached file, does it run? So without the ARIMA related operators?

What do you mean by "I run Job Agent manually"? Once it's started and you see it in the queues list (green indicator) it should work normally.

Samir · July 2020

@aschaferdiek

The process you attached runs in normal job agent but only fails as a web service.

The sub process works when runs in normal job agent and fails only as a web service. I tried both alone and with ARIMA related operators.

While installing the RM server, I forgot to include Job container so later I manually run RM job agent via Terminal, also I had to change jobagent.container.memoryLimit in agent properties.
and yes, I see all the processes in the executions, successfully run.

aschaferdiek · July 2020

When you run the web services via the "test button", does this work or do you get the same error? Could you maybe attach the entire server.log file?

Samir · July 2020

@aschaferdiek

The server log I attached at the beginning is when I run the web service via "Test" button in RM server web UI.

I haven't tried it any other way.

This is from the web service I tried running via the test button minutes ago.

This issue is really hard to track down as it's working on our end, so because of this we think that it could be setup related or that classes/extensions are loaded more than once and thus the casting is broken.

Would it be possible to setup an instance on a separate machine, starting from scratch and just with the rmx_web and dependent extensions so we can rule out that the setup is causing this?

I tried with the previous version of the rapidminer server and the problem solved with the GET PAGE operator.

java.lang.ClassCastException: com.rapidminer.operator.web.io.MultiThreadedCookieManager cannot cast
