Error injecting runtimeService Bean

[fnoorie]

I get the following error when I try to inject the runtimeService

Caused by: org.springframework.beans.ConversionNotSupportedException: Failed to convert property      value of type 'org.activiti.engine.impl.RuntimeServiceImpl' to required type 'org.activiti.engine.RuntimeService' for property 'runtimeService'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.activiti.engine.impl.RuntimeServiceImpl] to required type [org.activiti.engine.RuntimeService] for property 'runtimeService': no matching editors or conversion strategy found

I tried a bunch of ways to inject the bean: via @Autowired, @resource, as a property but it seems to fail for the same reason everytime

Could you have different activiti libs present in your classpath?\\

If not:
Could you create jUnit test to reproduce this issue?

Here are the activiti jars I am using:

I tried with Junit and it works, not sure how to proceed now.

I tried even the get bean way:

ProcessEngine processEngine = (ProcessEngine) ApplicationContextProvider.getContext().getBean("processEngine");

I get a ClassCastException

[martin_grofcik]

I guess classloader has access to 2 different implementations. Check classpath.
