If you are not encountered any other exception in CEP (believe, you are trying out with standalone CEP 3.1.0), then only possible reason is extension jar is not picked by the OSGI environment.. Below steps may help you to check the issue,
1) Are there many extension jars available? Whether they have same package name ? If yes, you cannot have like that in OSGI environment then some jars which have the same package name will not be picked by the OSGI class loader.. You need to have unique package name.. 2) Check how many OSGI bundles are exists in dropins folder.. If you are put a jar in to lib directory then it will be converted in to OSGI bundle and copies to dropins folder. Then if you delete a jar in lib then you also need to delete it from dropins as well.. If you cannot resolve the issue by following above approaches then there might be an issue with siddhi extension and/or need to check deeper on that..
