Currently been struggling to deploy my war file in WAS 8.5 but everytime I start my war file, an error occur.

Exception caught while initializing context: {0}org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/my-servlet.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: javax/persistence/Table.indexes()[Ljavax/persistence/Index;

I just don't know where this error is causing. I implemented other OP's issue which is somehow associated to my current issue but regrettably no luck from my end. Any help guys?

EDIT

After adding hibernate-entityManager dependency in my pom, it created another issue.

Exception caught while initializing context: {0}org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in ServletContext resource [/WEB-INF/something-servlet.xml]: Cannot resolve reference to bean 'jpaVendorAdapter' while setting bean property 'jpaVendorAdapter'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jpaVendorAdapter' defined in ServletContext resource [/WEB-INF/something-servlet.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter]: Constructor threw exception; nested exception is java.lang.IllegalStateException: Failed to determine Hibernate PersistenceProvider

Solution

To those looking for an answer to this question,

we downgraded our JPA from JPA2.1 to JPA2.0 (because WAS8.5 cannot support JPA2.1)

see this table for dependency issues between JPA2.0/JPA2.1 - WAS

because we are using springboot, we removed this dependency

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

and with the help of dependencyTree in maven, we're able to identify the dependencies attached to the deleted dependency(the one mentioned above) and added these dependencies:

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
</dependency>

<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
</dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.7.Final</version>
</dependency>

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>4.1.7.Final</version>

From my understanding, springboot uses the latest version (JPA's latest version is 2.1) thus we did this solution.
