Hibernate Exception after DXP Migration

[Jatinderveer Singh，修改在6 年前。]

So this is something new, did not expect anything like this to happen and need to figure out if Liferay DXP is playing a part somewhere in this?

I have migrated my 6.2 EE Ant JSF portlet to DXP JSF Maven portlet. No compile time errors, so i am ok to believe that all the Jars are in place and i am using the exact same jars as in 6.2 . Now everytime i run my portlet in DXP. I get the following error :

The amazing thing is this connection code without any modification works as expected in 6.2 . Now that i am getting a parse exception i know that the location of the file is correct. Is there any chance OSGI is causing this disruption? Now i know I am not using Service Builder to do this stuff for me, but could that be a reason that i definitely need to use ServiceBuilder approach in DXP or is it still a developers choice?
If you can help me figure out whether this is at Liferay Level or Hibernate Level, it would be tons of help.
I have tried modifying the hibernate file with namespaces and all but error is still the same.If I put the file in some other location it does given me FileNotFound, but when it is in the right location the error persists.

In a Liferay environment, there are many benefits to using ServiceBuilder instead of hibernate or JPA. But if you need to continue with hibernate of JPA for now, we can try to help find out why hibernate can't find the file.

First, what version of hibernate are you using? Also, please provide a simple SSCCE (Maven-based, if possible) that reproduces the problem. It might be easiest to start by generating a project from one of our archetypes. You can find instructions for that on the home page of liferayfaces.org.

Initial development of the portlet was without SB and now there is not enough time to spend to move to SB
I have attached the smallest extract from my code to reproduce the issue with same exception. I am generating the project using liferayfaces and i started with 3.6.7Hibernate on 6.2 it remains same even if i go till 3.6.10. Beyond that there are changes to be done to Hibernate code itself, which i would rather not do at this moment.
Attached file is Maven source but in 6.2 we were using Ant structure. You can have a look at logs to see the error.

Thanks,

Thank you very much for the SSCCE. I was able to reproduce the problem.

It was caused by the transitive "dom4j" dependency of hibernate-core. That might be an incompatibility with Liferay 7.

I was able to make the problem go away by adding the following exclusion:

		<dependency>
			<groupid>org.hibernate</groupid>
			<artifactid>hibernate-core</artifactid>
			<version>3.6.10.Final</version>
			<exclusions>
				<exclusion>
					<groupid>dom4j</groupid>
					<artifactid>dom4j</artifactid>
				</exclusion>
			</exclusions>
		</dependency>

After rebuilding and redeploying the war artifact, I also found that it required the following dependency:

		<dependency>
			<groupid>org.hibernate</groupid>
			<artifactid>hibernate-validator</artifactid>
			<version>5.4.1.Final</version>
		</dependency>

After that, it asked for a JDBC driver dependency as well, but I think that would be determined by your environment.
