I am trying to save the data in my db (already saving it in lportal). For that i created a connection file and wrote all the required code. Like we do in JDBC. I am able to store the data in lportal(default one) but when I tried to save it in my db. I am getting below exception.
java.lang.ClassNotFoundException: org.postgresql.Driver cannot be found by ""
I tried adding the JAR to the folder but still the same thing. In JDBC we can add the JAR in lib folder but it doesn't seem to work here.
I also tried adding the jar to the tomcat bundle in lib and lib/ext folder but nothing seems to happen.
I also added the following line in my build.gradle file but no results.
compile group: 'org.postgresql', name: 'postgresql', version: '42.2.25'
Can someone help regarding this as where and how to add JAR or any other file so that I can save the data in db at the same time as lportal.

CodePudding user response：
At start up liferay provides the option using which we can change liferay database. Following is the steps for the same.
1.1) Create a database in postgresql(like lportal).
1.2) Select the change database option at liferay start up.
1.3) Enter your databse url,username and password.
You can create a file with name portal-ext.properties in Liferay root folder(check attached screen shot).
Add following database configuration.
Postgresql
jdbc.default.driverClassName= enter driver
jdbc.default.url= enter URL
jdbc.default.username= enter UserName
jdbc.default.password= enter Password
CodePudding user response：
First of all your question is very confusing. So you want to use a PostgreSQL for your Liferay Portal right? You configured everything correctly and downloaded the driver from https://jdbc.postgresql.org/download/postgresql-42.4.1.jar?
Just put this driver in tomcat/lib not ext (maybe it is not configured to load). Restart the server.
Please provide the complete startup log output.
