JBDS 7 hibernate settings issue in JPA project

pepelara Aug 20, 2013 1:24 PM

Hi,

I am trying to set hibernate in my JPA project and going to project properties

select Hibernate settings and the details show the following error,

[Classpath]: Could not create JPA based Configuration

Here is the issue in jira,

https://issues.jboss.org/browse/JBDS-2452

with status -> Closed and Resolution -> Won't fix

Is this meaning we could not develop this kind of

features in JBDS?

Please help

Thanks,

jose

This issue has a workaround description, which says:
If the error occurs, one needs to open the Project properties > Hibernate Settings > select the console configuration and click on details.
The persistence unit name must be set, using the name found in the main persistence.xml.
Does it help?

Hi Denis,

Thanks for your reply.

Just a question because I am not sure about what do you mean when you say 'main persistence.xml'.
If I am not wrong I understand it is the only one persistence.xml file in the project and if it is the case,
when I get the details, I set the unit name to the one in the persistence.xml file. And still does not work,
I mean the same error persists.

Thanks,
Jose

the error should only occur if there are multiple persistence.xml's on your classpath.

Can you check if maybe your classpath contain the same folder containing your persistence.xml twice ?

Hi Max,

Thank you for your reply.

I have a project folder 'jpatest' and the persistence.xml is in two subfolders,

src -> META-INF
build -> classes -> META-INF

so I wonder if this is the problem

Thanks,

It is ok. I was getting wrong.
This is what I did to do it work,

Create a JPA project
Create hibernate.cfg.xml file
Set the persistence.xml to the hibernate.cfg.xml file (property)
Create entities from tables
Add hibernate libraries to the project

On the other hand, the step 4 could be to switch to hibernate perspective
and set the Hibernate Code Generation Configurations that works ok.

Thanks,
jose

the file in build is the output from copying/building src. Just like you got .java in src and .class in build.

If *both* of these folders are on the classpath of the project - then yes, there will be problems.

It should only be the build one.

Can you check your classpath under Java preferences for the project ?

The steps you do here makes it not use JPA, but use plain hibernate setup. Just so you are aware that is not going to give the same behaviors

Hi Max,

Yes I decided to go to plain hibernate because this was my initial idea
but in a early future I will try out JPA so I will have this thread present.

Thank you Max, thanks a lot,
