Could not find the main class: com.mypkg.Main. Program will exit.
#EDIT
i have the project structure under Eclipse below, which works well with Hibernate as the persistence provider.
bin
|_META-INF
| |_persistence.xml
|_com
|_mypkg
|_Main.class
|_MyEntity.class
Upgrading to eclipselink to the following resolved this issue for me:
<dependency>
<groupId>org.eclipse.persistence</groupId>
<artifactId>org.eclipse.persistence.jpa</artifactId>
<version>2.7.3</version>

According to my observation as i am using the jboss7 wher we have hibernate 5 version dependencies and the pom.xml contains 4.2.18 hibernate dependencies and i am using compatible hibernate search for the 4.2.18 hibernate version which results in conflicts of the dependencies between the jboss hibernate modules and dependencies from pom.xml caused this error..
Basically its hibernate dependencies compatibility issues
u can go throw the following link froenter link description here
Performing weaving (static or dynamic) results in the following error:

I didn't get this error with EclipseLink 2.6.5 and if I turn Weaving off everything works fine.
Is there a way to work around it? What triggers the error?
The NPE is a bug, as it isn't performing a null check and throwing a more specific error: This error could only occur if you've specified a named native (SQL) query on your entities that references a SqlResultSetMapping, but you haven't defined any result sets mappings. See https://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Querying/Native#SQL_Result_Set_Mapping for documentation and an example.

The JMS connection factories come in sever flavors:
com.ibm.mq.connector.outbound.ManagedConnectionFactoryImpl
com.ibm.mq.connector.outbound.ManagedQueueConnectionFactoryImpl
com.ibm.mq.connector.outbound.ManagedTopicConnectionFactoryImpl
You have:
Caused by: org.springframework.jndi.TypeMismatchNamingException: Object of type [class com.ibm.mq.connector.outbound.ConnectionFactoryImpl] available at JNDI location [it00EventQueueFactory] is not assignable to [javax.jms.QueueConnectionFactory]
You are providing a ConnectionFactory, but the code is expecting a QueueConnectionFactory.
You should change your IBM MQ configuration to provide a:
com.ibm.mq.connector.outbound.ManagedQueueConnectionFactoryImpl
I found the solution for this. we need to add dependencies in JBoss-deployment-structure.xml file like below.
dependencies>
<module name="javax.jms.api" export="true"/>
<module name="deployment.wmq.jmsra.rar"/>
</dependencies>
When I try to generate Database Tables from my project's Entities the Exception below is thrown.
If I understand correctly, the Exception suggested to specify java.naming.factory.initial:
So I went through several parts of JBoss-Documentation, not quite sure what I was looking for, did experiments with a jndi.properties-file and realized in the end that I am absolutely clueless.
BTW: The generation of Entities from Tables (so the other way round) works without problems.

please let me know what is the problem ???
Check whether the connection to mysql is defined in the services window or not. It usually looks like 'jdbc:mysql://localhost:3306/mydb[root on Default schema]"
