Fall to call any flow service in Developer

Hi all,
I met this problem in my wM6.1: When I call any build-in service in Developer, there is a error message prompt: Could not run ‘myService’.

java.lang.NoSuchMethodError: com.wm.lang.flow.SchemaProcessor.put(Lcom/wm/data/IData;Ljava/lang/Object;)Ljava/lang/Object;
But I connect another IS server, it worked fine, It’s seems some problem in my IS, so I re-installed it, but the issue still exist.

Would you help me for this issues?


It is fixed by Kyle,thanks!

what’s the reason?
