Just paste the Logs in the body of the email. Hi guys, I appreciate your guidance. However, let me share some considerations and perhaps you can guide me better: * My focus is to see if we can demonstrate Fineract working with Apache Trafodion instead of PostgreSQL + Cassandra. Initially the focus will be to switch PostgreSQL with Trafodion using the EclipseLink/JPA infrastructure that has been put in place. * To that end I am not interested in exploring all the intricate details of the components or tools used by Fineract, since that would take me a lot of time and effort with little value, when you experts are already taking care of that part. That is, I have no idea what npm does or why. I am just following the directions on the build web page so I can get it running with PostgreSQL + Cassandra, then see how I can switch Fineract to use Trafodion, and then run the same with Trafodion to hopefully get the same results. * I am doing this on a Windows 10 Pro OS x64 PC Intel i7-6500U 2.50 GHz CPU, 2592 MHz, 2 Core(s), 4 Logical Processor(s) with 16 GB of physical memory and total virtual memory of 35 GB with around 22.5 GB available. If I need to start the process again on some other system/OS I can, but from what I have been told so far, it should work on this laptop. * I ignored putting the fineract-cn-fims-web-app directory in a integration-tests directory since in the past the host directory path has been irrelevant for most purposes. But I guess I was wrong in this case. So, I changed that and built Fineract CN again successfully, i.e. completed Step 2 recommended option 1. But when I ran Step 3 Option B – with persistence Command I, I am still getting errors. I don’t have the log from the beginning (my bad) but have most of the relevant parts of the log attached, if that gives any pointers as to what the issue may be. * If I should follow a different recipe to do what I need to do in order to move forward, I am more than willing. I don’t know if a docker build is what will work for what I want to do, since my intent is not to just demo / use the product, but rather to get it running with tests as it currently stands and then switch to Trafodion with whatever effort that requires (potentially source or configuration changes), and then run the tests again to prove that it all works just the same. Later I would like to run some performance tests at scale to demonstrate where Trafodion can really make a difference for Fineract customers needing high-scalability. But I need to get it all working first. So, any guidance would greatly be appreciated. Thanks for your patience and all your help!

Hi Juhan, I think you are right and it is time to rewrite the build instructions for Fineract CN to adopt the Docker approach. Anyone interested in doing this work? On Fri, Dec 6, 2019 at 7:50 AM Juhan Aasaru <aas...@gmail.com<mailto:aas...@gmail.com>> wrote: Hi! The problem with npm is caused by the fact that you have not cd into correct directory. The instructions under step #4 have this: cd into ‘integration-tests/fineract-cn-fims-web-app' Anyway, we can all agree that the build instructions of Fineract-CN are almost impossible to properly follow. And actually there is no need to use demo server. Demo server sets up the system but its quite untransparent and difficult to understand for a newcomer. Don't get me wrong, it is a great resource afterwards when learning how to call micro services from code and how to use listeners. To set up the system for the first time I recommend to use Docker-Compose with Postman instead: https://github.com/apache/fineract-cn-docker-compose#2-deploy-fineract-manually-using-postman This is all tested several times and should work like a charm. The following is an idea of mine that is not anywhere documented yet due to lack of time. Based on Docker-Compose process we could also create instructions where micro services are not started within Docker but they are started directly (run from IDE or java -jar ...). Docker-Compose instructions include creating .env file with common properties (and RSA keys). To run micro services directly basically a similar file should be created, let's call it applciation-locally.yml and then when starting apps this file should be passed as flag: --spring.config.location=../application-locally.yml Provisioning is be done with Postman (see instructions at fineract-cn-docker-compose) - this way one understands better what steps are taking place during provisioning.

I think I got off the track right at the beginning of Step 3: Orchestrate Microservices Using The Demo-server. It said “… consider manually orchestrating …”. I thought I needed to go to https://github.com/vishwasbabu/ProvisioningFineractCN. That is where it says start ActiveMQ. Which is why I did. I abandoned that effort when I realized that “consider” meant optional, and I did not really need to do that, since that whole key generation was getting a bit complicated on Windows 10. But then ActiveMQ was still running when I proceeded with the rest of the instructions to build. My bad! Because I had started ActiveMQ, initially demo-server immediately complained about not being able to use port 61616. In fact, the instructions say that this port should not be in use before starting demo-server. I guess I did not pay attention to that part until I got that error. I then stopped ActiveMQ, changed the port 61616 it was using, to 61615, and restarted it (doh!). Demo-server then ran for a long time. But then it gave me a slew of connection refused errors for port 61616, even though ActiveMQ was not using it, and not that the port was being used. Regardless, I stopped ActiveMQ and this time ran with Command II in the documentation. I did not run into the connection refused error! This time I got some [DicoverClient-n] errors that c.n.discovery.TimedSupervisorTask – task supervisor timed out But demo-server kept going after those timeouts and has now been running for 3 hours with no message "INFO o.e.jetty.server.AbstractConnector - StoppedServerConnector@1bdb0376{HTTP/1.1,[http/1.1]}<mailto:StoppedServerConnector@1bdb0376%7bHTTP/1.1,%5bhttp/1.1%5d%7d>" written to any of the logs as yet. I guess I should have direct standard out to a log since it does not seem to be capturing everything in the logs and I might have just missed that message. I decided to proceed to step 4 but I get the following when I run npm i … c:\Apps\fineract-cn-demo-server>npm i npm WARN saveError ENOENT: no such file or directory, open 'c:\Apps\fineract-cn-demo-server\package.json' npm notice created a lockfile as package-lock.json.

Thanks Awasum for the response. I think that's the issue too @Rohit, it's not necessary to configure a standalone ActiveMQ when running the demo-server. This library (https://github.com/apache/fineract-cn-command) helps to set up an embedded broker. Also, what is the state of this issue https://github.com/flyway/flyway/issues/2103 Warm regards.

So if you already have an activemq installed on your host, then thats what is causing the port in use exception. Hope this helps.

He ran into an issue: Could not connect to broker URL: tcp://localhost:61616. Reason: java.net.ConnectException: Connection refused It so happens that 4 months later I have run into the exact same issue. Except that I am running everything on my Windows 10 laptop. Also, I installed and ran ActiveMQ on my laptop. In fact, the demo server got an error initially since it found that port 61616 was being used. So, I modified the activemq.xml file to change that port to avoid the conflict. Then the demo server started all the application services, and then at the end ran into the error above. You responded to Eric and said that you would provide a resolution to this problem. Don’t know if you have a resolution that I can use to move forward. The Demo server created the appropriate databases and keyspaces in PostgreSQL and Cassandra respectively.
