ClassNotFoundException: com.appdynamics.apm.appagent.api.NoOpInvocationHandler

New Member

I need to post some custom metrics to AppDynamics for analytics purpose. So I am trying to create new Transaction from application source code using below code.

Transaction transaction = AppdynamicsAgent.getTransaction(getProcessorName().name(), null, EntryTypes.POJO, false)

However getting below while loading AppdynamicsAgenet class


Caused by: java.lang.ClassNotFoundException: com.appdynamics.apm.appagent.api.NoOpInvocationHandler
at java.lang.ClassLoader.loadClass(
at sun.misc.Launcher$AppClassLoader.loadClass(
at java.lang.ClassLoader.loadClass(
... 92 common frames omitted​


Anyone know how to fix this?

Hi @Priyaranjan.Behera,

I did some searching and I found this info, but I don't think it's related to your issue, but wanted to share just in case.

javaagent should be instrumented to the local Java application along with the java agent API. Since you didn't instrument the java process with the Java agent, you are getting that exception.
So, can you please try to instrument the java process with the javaagent along with the javaagent API and see how it goes?
