Hi there,

We use MyEclipse for building EJB 3 / JPA entity beans. Each entity bean has a super class that contains the id and version field. The super class is in a different (utility) project.

At runtime everthing works fine, but MyEclipse shows the following error message:

“Entity does not have an id”.

We updated the metadata using a refresh. This helped for a while but now the message is back and will not disappear, even after a metadata refresh.

It seems it has something to do with the mappend superclass being part of another project.

Any ideas?

Thanks in advance,

Martijn.

Can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

Are you able to reproduce this issue with a brand new project as well?

[MartijnBaels]

The same is true for a brand new project and it makes no difference whether the project depends on the utility project sources or on the utility project’s jar file.

MartijnBaels,
Can you please paste you installation details here for me (MyEclipse > Installation Summary > Installation Details).

Also, can you list the steps to help me reproduce this issue at my end or send me a sample project to help me reproduce this issue at my end. You can hit the *pm* button at the bottom of my post and send me the project.

Hi there,

Sorry but I don’t have any source code or projects available to send to you, but you can reproduce the issue like this:

– Create a utility project that contains a mapped JPA superclass that contains the primary key (objectID Long) and a version field (updateCount Long)
– Create an EJB 3 project with JPA reverse engineered entities that inherit from the class coming from the utility project
– When you refresh meta on the JPA project it complains about not having an id field (even though it should be inherited from the superclass)

Here is my installation information:

Hi I’m having the exact same issue, has it been resolved? I’m on myeclipseide 7.0

[Riyad Kalla]

Sorry guys, the JPA metadata validator hasn’t been expanded to do the class resolution across project boundries like that. This has not been changed in 7.0 but it’s been filed as a bug for us to look into.

Hello,

I just wanted to know if there might already be a solution for this?
Because I’m also having the same issue.

Thanks and have a nice day,

Jochen

Jochen,
I’m afraid we don’t have a solution to this problem as of now. Sorry about that.

There is no way to get around it at this time but to hide the error you CAN disable Metadata analysis for the project reporting the erroneous error by going to Project > Properties > MyEclipse > Java Persistence.
