java.lang.ClassNotFoundException: org.flowable.admin.conf.WebConfigurer


we’ve downloaded the 6.0.0 RC1 version, imported the wars to eclipse and configured the projects to Maven. No matter that some projects are running fine, the flowable-admin and the flowable-rest are returning ‘java.lang.ClassNotFoundException: org.flowable.admin.conf.WebConfigurer’ and ‘java.lang.ClassNotFoundException:’ errors.
I’m not that skilled in java/eclipse, so I request your help to try to solve this problem - which I believe that can be mine (not a war problem, let’s say) and ‘easily overtaken’.

Can you please help me?


Hi Daniel,

What are you trying to do? Do you want to add your own implementation / modify Flowable code?
If you’re trying to run the Flowable admin and REST apps it’s easier to deploy these wars to a Tomcat server.
Or; if you have docker installed you can use the Flowable docker images to get up and running quickly.
For this you can you the following command;

./docker/ (start | stop | info)

Hi Yvo,

thank you very much for your reply. In fact, we’re trying to understand
what’s the best approach to have some custom (extended) user-tasks - that
is, we’ve a requirement where the functional department wants to design
business processes and, in that way, we’d like to allow them to have a
specific area in a modeler/designer, where they could include (in a
process) some custom (in flowable perspective) tasks like: authentication,
work queue (we need to relate bpm processes to business requests with
specific Id’s), decision, payment…
…Also, our platform is supported by Liferay (in the user interface/portal
layer) and we already have a portlet that is executing a selected process
(specifying the engine thru jndi and a processdefinition, in the portlet
preferences)…now, we want to improve this functionality to have a more
business oriented portal/bpm platform (specifying the engine thru jndi, a
processdefinition and a UserTask(defined in the process), eventually in the
portlet preferences)…

In this way, can you tell me what you consider the best approach? Or, in
case you’ve had this thread before, can you please send me the link of the

Hope that I’ve been explicit - if you need more info, don’t hesitate to
contact me.
