I have a webapp with maven, eclipselink, jpa, spring 5, jsf2.3, java 8, primefaces 11 deployed on tomcat 8.5.
For a software modernization question I just successfully ported to tomcat 9 with java 17 keeping spring 5 and all the rest of the libs.
But this was just an intermediate step towards porting to tomcat 10.0, java 17 and advancement to jakarta of all dependencies including advancement to spring 6: this port is giving several problems.
I've been stuck on a problem with entity manager configuration for a while now.
The application is configured from a class that extends org.springframework.web.servlet.support.AbstractDispatcherServletInitializer, inside the onStartup method I define the Faces Servlet and other jsf/primefaces stuff. Inside the method getRootConfigClasses I list my various spring config files:
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {
WebMvcConfig.class,
RepositoryConfig.class,
SecurityConfiguration.class,
CachingConfig.class,
MethodSecurityConfig.class,
HttpClientConfig.class
};
}
the problem is with RepositoryConfig, this is the class:
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories("here.my.package.with.repositories")
public class RepositoryConfig implements TransactionManagementConfigurer {
protected Logger logger = LogManager.getLogger(this.getClass());
@Autowired
@Qualifier("config")
private Config config;
@Bean(name="entityManagerFactory")
public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
emf.setDataSource(dataSource());
emf.setPackagesToScan(new String[] {
"here.my.package.with.entities"
});
emf.setJpaVendorAdapter(jpaAdapter());
Properties jpaProperties = new Properties();
JpaDialect jpaDialect = new EclipseLinkJpaDialect();
emf.setJpaDialect(jpaDialect);
jpaProperties.put("eclipselink.weaving", "false");
emf.setJpaProperties(jpaProperties);
return emf;
}
@Bean(name="jpaAdapter")
public EclipseLinkJpaVendorAdapter jpaAdapter() {
EclipseLinkJpaVendorAdapter hjva = new EclipseLinkJpaVendorAdapter();
hjva.setDatabasePlatform("org.eclipse.persistence.platform.database.MySQLPlatform");
hjva.setGenerateDdl(false);
hjva.setShowSql(false);
return hjva;
}
@Bean(name="dataSource")
public DataSource dataSource() {
JndiTemplate template = new JndiTemplate();
DataSource ds = null;
try {
ds = (DataSource) template.lookup("java:/comp/env/" + config.get("repository.jndi.name"));
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return ds;
}
@Bean(name="transactionManager")
public PlatformTransactionManager transactionManager() {
JpaTransactionManager jpaTransactionManager = new JpaTransactionManager();
try {
jpaTransactionManager.setEntityManagerFactory(entityManagerFactory().getObject());
jpaTransactionManager.setDataSource(dataSource());
} catch (Exception e) {
logger.error(e.getMessage());
}
return jpaTransactionManager;
}
@Override
public PlatformTransactionManager annotationDrivenTransactionManager() {
return transactionManager();
}
@Bean(name="persistenceAnnotation")
public PersistenceAnnotationBeanPostProcessor persistenceAnnotation() {
return new PersistenceAnnotationBeanPostProcessor();
}
}
I get this error:

The same class "RepositoryConfig" has no problems in the old versions of the webapp indicated at the beginning of this post. Has anyone run into a similar problem?
