thank you guys, i found the problem, this issue happened cause i worked with old jersey version, i just changed the version value from 2.16 to 2.22, and run Maven>update project, now it's working fine.

On Spring Boot 2.5.X data.sql scripts are now run before Hibernate is initialized. If you want to use data.sql to populate a schema created by Hibernate try adding the following to your application.properties spring.jpa.defer-datasource-initialization=true.
# mySQL configuration
spring.datasource.url=jbdc:mysql://localhost:3306/employeemanager
there's a typo, its supposed to be jdbc not jbdc
As I do remember, I was facing similar issue during integration.
Could you please validate your pom.xml and application.properties/application.yaml configurations as below.

When I run the my spring boot project from the my IDE it creates the database and war get deployed to the tomcat. I was hoping to see the same thing when I deploy the war file manually to tomcat and restarting the tomcat. But it seems the database is not created during the deployment. What am I missing here.
As I remember, In the past, I have done the same thing before and it worked, Is it something to do with the Spring Boot or is it a problem with the build plugin provided in the pom file
Here is my POM file.

I figured it out.
I changed the Application class to
#Configuration
#ComponentScan
#EnableAutoConfiguration
public class Application extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<Application> applicationClass = Application.class;
}
and removed the following plugin
<!-- <plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin> -->
and added
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
It works :). All the best
I'm attempting to use Maven to organize a GWT(GWT-Platform, to be precise) project which uses Guice-persist to map my data objects back to MySQL from Eclipse. I am not having any luck.
I've based my code off of the GWTP basic sample's Maven configuration, which I was able to get working. Now that I'm adding Hibernate dependencies into the pom.xml file, I can't seem to get it to run successfully again. Currently, I'm getting the following error:
1) Error injecting constructor, javax.persistence.PersistenceException: No Persistence provider for EntityManager named myappdb
at com.gwtplatform.samples.basic.server.ApplicationInitializer.<init>(ApplicationInitializer.java:8)
while locating com.gwtplatform.samples.basic.server.ApplicationInitializer
I create my PersistModule when setting up the injector, as such:
Injector inject = Guice.createInjector(new ServerModule(),
new DispatchServletModule(), new JpaPersistModule("myappdb"));
inject.getInstance(ApplicationInitializer.class);
My persist file looks like the following:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

As you can see, then names of the units match. Additionally, I have my persistance.xml file saved in the src/main/webapp/META-INF directory of the project. I've tried running the project using the /src/main/webapp/ directory as the base of the war file, as well as the matching directory in /target/ and neither are able to overcome this error.
Any pointers would be greatly appreciated! I've been staring at this for 2 days now.
Put your persistance.xml file in src/main/resources/META-INF.
