Migrating Apache OFBiz from Derby to MySQL

Question

I tried migrating Apache OFBiz from derby to mysql using this tutorial. Prior to making changes in entityengine.xml, I executed ofbiz with defaultData and exported data into xml files from webtools. After that, I made all the said changes, created working db schemas and users. But when I run the ofbiz after these changes, I get an exception with the message

`invalid delegator name!`

Why is that? I am currently using 16.011 version of OFBiz. Below is how my delegators and datasources look like

The Apache OFBiz package structure was changed recently and the mentioned tuturial was not completely up-to-date. I have changed the "org.ofbiz." entries to "org.apache.ofbiz." in the tutorial.

Please try again and report if everythings works for you now.

(I use OFBiz version 16.11.02, latest version at this time)

Create user for database:

create database ofbiz;
create database ofbizolap;
create database ofbiztenant;
use mysql;
select database();
create user ofbiz@localhost;
create user ofbizolap@localhost;
create user ofbiztenant@localhost;

UPDATE mysql.user
    SET authentication_string = PASSWORD('ofbiz'), password_expired = 'N'
    WHERE User = 'ofbiz' AND Host = 'localhost';
FLUSH PRIVILEGES;

UPDATE mysql.user
    SET authentication_string = PASSWORD('ofbizolap'), password_expired = 'N'
    WHERE User = 'ofbizolap' AND Host = 'localhost';
FLUSH PRIVILEGES;

UPDATE mysql.user
    SET authentication_string = PASSWORD('ofbiztenant'), password_expired = 'N'
    WHERE User = 'ofbiztenant' AND Host = 'localhost';
FLUSH PRIVILEGES;

grant all privileges on *.* to 'ofbiz'@localhost identified by 'ofbiz';
grant all privileges on *.* to 'ofbizolap'@localhost identified by 'ofbizolap';
grant all privileges on *.* to 'ofbiztenant'@localhost identified by 'ofbiztenant';

Use port number, Default, it is 3306

 jdbc-uri="jdbc:mysql://127.0.0.1:3306/ofbiz?autoReconnect=true"

Find word derby, change it to mysql.

Then

gradlew cleanAll --info
gradlew loadDefault --info
gradlew ofbiz --info
