One-process deployment of Fineract CN

[Isaac Kamga]

Happy weekend fineracters,

Hope this email finds you in good health.

In an effort to facilitate local development of Fineract CN, I picked up
the One-process deployment issue [1] which when resolved can enable
developers to run the platform in a single process.

Some research led me to the possibility of running each microservice in a
it's own ClassLoader while ensuring that the ServiceRunner uses a single
JVM to run in a single process. After having tried to adapt the method in
[2] where several Spring Boot apps are launched in the same process to our
Service-starter and demo-server, I encountered this error [3]. The code of
the workdone so far is on the *oneprocess* branch of my fork of
service-starter[4] and demo-server [5].

@Myrle Krantz   Is there a way to have the "java -jar
xyz-service-boot-0.1.0-BUILD-SNAPSHOT.jar" command run a single Thread as
opposed to running in the process assigned by ProcessBuilder() ?

@Markus Geiss  , is it possible that what could help in
this case is using an entire Pool of threads to get this executed ? Asking
as you developed the fineract-cn-async [6] library and I observed that upon
running demo-server, when the processors on my machine get exhausted, the
logs indicate that a separate thread (not main) shows up to run any
available service like Notifications and Groups.

Any help from the community would be much appreciated.

At Your Service,
Isaac Kamga.

Re: Mifos/Fineract set-up - Tomcat and MySQL issue

[Vishwas Babu]

Hi Supreeth,

Welcome to the Fineract community :).

Fineract 1.2 works with MySQL server version 5.7.x. Can you check the
version of MySQL you have installed?

The relevant error snippet from your log is

Caused by: org.drizzle.jdbc.internal.common.QueryException: Could not
connect: Client does not support authentication protocol requested by
server; consider upgrading MySQL client
at 
org.drizzle.jdbc.internal.mysql.MySQLProtocol.(MySQLProtocol.java:227)
~[drizzle-jdbc-1.3.jar:na]
at org.drizzle.jdbc.DrizzleDriver.connect(DrizzleDriver.java:89)
~[drizzle-jdbc-1.3.jar:na]


Regards,
Vishwas

 Hello ,
 I am Supreeth , studying 2nd year at International Institute of
 Information and Technology , Hyderabad. Based on the provided instructions,
 I was trying to set-up Mifos/Fineract. I am getting stuck with Tomcat and
 MySQL. I tried Tomcat 7 and 8, getting similar issues.

 I request someone to help me in the set-up so that I can fix few issues
 before I apply for GSOC 2019.

 Looking forward to hearing on the support
