I have a Spring scheduled method in Windchill and want to call some methods, but i get the erro that there is no active method context. So I tried to call the method via RemoteMethodServer.invoke(). This actually works but i always get the following error in the log:

2023-12-07 10:44:13,675 ERROR [pool-14-thread-1] wt.method.client  - RemoteMethodServer.invoke() called on default method server from within method server! Probable bad loopback code! java.lang.Exception

Is there a way to get the active method context without calling RemoteMethodServer.inoke()?
The code runs in the ServerManager I think.
Thanks!

I solved it by calling a rest servlet.
The Rest servlet has an active method context so there is no preoblem.

Hi @dullnigAlex 

I do not use invoke, I use just getDefault

RemoteMethodServer.getDefault().setUserName("----");
RemoteMethodServer.getDefault().setPassword("----");

Then I use standard Windchill methods.

Does your scheduler method calls the Windchill http address by URL?
