Springboot with Elastic search XContent conflict

Im having a java micro-servcie working with Elasticsearch and was working great, I decided to move it to Springboot and all good except one problem that I was facing for hours and can't find any solution online.
java: cannot access org.elasticsearch.xcontent.ToXContentObject
class file for org.elasticsearch.xcontent.ToXContentObject not found
I gave it a try to play with the versions here and there based on some some advices but still. I also check the maven tree and can't see any elastic search stuff injected from Springboot. Any one can help on this plz?

I upgraded the springboot version from 2.6.3 to 3.0.2 and its now working fine :)

I think you are just declared a lot of redundant artifacts in pom.xml that is related to Elastic so there is a conflicts between dependecies.
Try to use just this ones:
<dependency>
<groupId>org.opensearch</groupId>
<artifactId>opensearch</artifactId>
<version>1.3.0</version>
</dependency>
<dependency>
<groupId>org.opensearch.client</groupId>
<artifactId>opensearch-rest-high-level-client</artifactId>
<version>1.3.0</version>
</dependency>
At least it is working in my project.

I used this dependency for enable swagger ui (openapi 3) specification, for more details refer this link
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>1.6.13</version>
</dependency>
I hope it will work without this dependency
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.0.0-M4</version>
</dependency>
And swagger ui link will look like this http://localhost:8080/swagger-ui/index.html#/
in documentation this is the format http://server:port/context-path/swagger-ui.html
learn more about context path from this link

An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.hibernate.cfg.annotations.EntityBinder.processComplementaryTableDefinitions(EntityBinder.java:1238)
The following method did not exist:
javax.persistence.Table.indexes()[Ljavax/persistence/Index;
The method's class, javax.persistence.Table, is available from the following locations:
jar:file:/C:/Users/INTEL/Desktop/timetablesystem/lib/javax.persistence.jar!/javax/persistence/Table.class
jar:file:/C:/Users/INTEL/.m2/repository/jakarta/persistence/jakarta.persistence-api/2.2.3/jakarta.persistence-api-2.2.3.jar!/javax/persistence/Table.class
The class hierarchy was loaded from the following locations:
javax.persistence.Table: file:/C:/Users/INTEL/Desktop/timetablesystem/lib/javax.persistence.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of javax.persistence.Table

You need to remove C:/Users/INTEL/Desktop/timetablesystem/lib/javax.persistence.jar from the classpath of your application as it contains an old version of the Java Persistence API that is incompatible with the version of Spring Boot that you're using. Exactly how that should be done depends on how you're running your application.

Can't see internal logs of Spring Boot app in $CATALINA_HOME/logs/localhost*.log

It's the second day I'm trying to find internal logs of my application. I've tried different approaches but none works.
What I have:
The application is run on Google cloud (maybe it makes scence)
Java 12
Spring Boot 2.1.7.RELEASE
Tomcat 9
How I am logging:
Firstly, I've tried simply use Lombok and its #Log4j2. I couldn't see any log in $CATALINA_HOME/logs/localhost.*.log.
Then I found several questions on stackoverflow. There is said that I need exclude spring-boot-starter-logging from pom.xml and add spring-boot-starter-log4j2. It didn't work, as well...
The third option was to use Slf4j. The same results :c
However, when I start the app via Intellij, Everything is logged. And what seems to me strange is when I type service tomcat9 status on the VM, I can see a bit of logs like part of Spring banner.

UPD:
The forth variant: as above, I added exclusions to pom.xml AND created log4j2.xml, where I specified log file.

Springboot , tomcat 8 , can't find driver for Postgres

I am using a spring boot applicaiton with Postgres.
But i can't get it running without adding my postgres.jar to the lib in the tomcat.
Are there any possibility to just use the postgres jar that i added within my application.
Realy want to issolate all my jar dependencies to my war and not change my Tomcat.
What i understand is it uses the the tomcat pooling for my application, are there any way to disable this?
This is my pom

You just need to add the postgres.jar as a dependency in your pom.xml.
