Using your tutorial, here: https://www.genuitec.com/docs/web-services/exposing-jpa-entities-via-rest-web-services/

and starting with a new project (re-creating JAX-WS service due to errors for no apparent reason in formerly-working project), I get to the step you see in the first screenshot below.

But, when I click “OK”, rather than see the tables I can use to reverse engineer, nothing happens.

The second screenshot shows how I configured the JPA settings.

I have the Zipcodes table open and viewable.

Can you please explain what’s going on?

I have the latest version of MyEcipse.

I can send you whatever other files you need.

Thanks,

Mork,

Sorry that you are seeing this issue. I just ran the tutorial step by step with MyEclipse Derby and could not replicate the problem at my end.
Can you please share with us the workspace log file which is located at workspace dir/.metadata/.log for further investigation?
Please change the extension to .txt and attach it here.

Please see attached (will eventually expose a JAX_WS service)

What I’m doing:

1. Creating a web project. (say to create web.xml)

2. Go to working DB Connection and open table.

3. Go back to project.

4. Add JPA Facet to the project.

5. Configure for Hibernate (database called “ZipCodeLookup”, table called “ZIPCODES”)

6. Attempt to reverse engineer the ZIPCODES table using the Generation mode.

7. Click “OK”

8. Nothing happens.

I resolved a JDK version issue you may see in the log. Now using Amazon Corretto 8 and have no project warnings.

Look forward to your reply.

Thanks!

I can email you the project, create a video, or whatever to help you help me figure out what’s wrong.

Thanks

[Mork]

Since I haven’t heard back from you in a while, perhaps you were able to reproduce the problem?

I’ve attached a quick video showing the Dao generation dialog on the MyEclipse program background.

As you can see, once I click “OK”, nothing happens.

The database with zip codes is open in the data explorer.

Mork,

Thank you for the detailed steps and video.
I tried with a simple maven web project and regular web project as well at my end but could not replicate the reported issue.

Which database are you working with? Can you please check if the generation works with MyEclipse Derby table as outlined in the tutorial? Follow the tutorial and see if the classes are generated to isolate the problem.

If you see no issues with the tutorial example, then please zip the project in question and attach it here to help us investigate further.

Are you working with the latest MyEclipse 2019.4.0? Please share with us your OS and Version details.

Tried clicking Cancel but that didn’t work either.

Created an entirely new workspace, went through the exposing JPA entities tutorial, but, again, when I clicked on the dialog to generate them, nothing happened.

Please give me an email address to send the zipped project. I really don’t know what kind of personal information might be stuffed inside it — like DB connections and such.

Thanks…look forward to hearing from you soon. 🙂

Mork,

To rule out database related issue, can you please check if the generation works with MyEclipse Derby table as outlined in the tutorial?

You can send us the zipped project to support@genuitec.com with a reference to this post or send it as a private message ( click on my username to view my profile and then click ‘Private Message’ to send it). Also share with us the MySQL driver jar version.

Sent 44 MB zip Workspaces file.

Forgot to include requested info: mysql-connector-java-8.0.12.jar

Thanks,

[support-swapna]

Mork,

I am afraid file of that size might not come through our forums/support email. Are you zipping the entire workspace or just the project?
Is it possible for you to host it elsewhere and share the link with me to download it?
Also please clarify if you are seeing the problem with MyEclipse Derby database as well.

I re-sent the email with just the project.

I also included a link for the entire setup video which demonstrates the issue (I even included music). 🙂

As I mentioned in the email, using Derby, it works, but using MySQL had worked previously.

I tried the latest version of the Connector/J driver (mysql-connector-java-8.0.18.jar) but had the same non-working issue.

Standing by…

Thanks,

Mork,

I see the problem with reverse engineering a MySQL table using the JPA Tools > Generate Entities and DAO’s at my end.
We are looking into it. In the meanwhile, reverse engineering from the DB Browser works for me.

Can you please check if you can reverse engineer the table from the DB Browser view?
Right click on the table in the DB Browser view > select JPA Reverse Engineering and choose the options as shown here : https://gyazo.com/87b365d63f29a020c2ba7b2d99037307

Thank you for reporting this problem.

I wish I could say that worked, but when I clicked “OK”, I got the error you see in the dialog attached.

Since I’ve never seen any error like this in MyEclipse, it seems there are some other bugs to fix at Genuitec. 🙂

Project now on hold until these MyE issues are resolved.

Standing by…

Thanks,

Mork,

Sorry about this issue. Can you please share the .log file located at workspace dir/.metadata/.log to help us get the full stacktrace of the exception logged? We didn’t get your project as our email server does not support large attachments.Please use the dropbox or google drive to upload the zipped project and share the link with me.

Can you please also check if you can reverse engineer a different table in the database or create a simple table in the database and see if it works with that table? Is there anything different with the tables in the database like table names starting with capital letters etc?

Apologies for inconvenience caused.

I will send you another email with a link to the project zip file and log file.

It’s odd that your email server can’t handle attachments about 2 MB as that’s all the second one I sent you had. Really????

Also, the database in question only has a single table. Plus, with an earlier version of MyE, the same database/table worked fine. This seems to be a severe issue in MyEclipse since I can’t reverse engineer either of the two ways that should work.

Please check your email.

The email will have the password for the zip file.
