Error during the generation of session bean

Hi all

EPCO: 12.1.1.1.0

I created the entities JPA through the Assistant of "JPA entities from Tables" for employees and departments.
Now, I want to create the bean in session using the Wizard "Session Bean of JPA entities.
I give it a name and select all of the available features and click on "Finish". Then I got the following error:
Error running the session bean generation task.
In the console error log, I see the following:

    To resolve this problem, you must add the missing entry in the PDATemplateBindings.jtp file:

    TABLE_ITEM_FOOTER=default/item/table/tableItemFooter.VM

    If you get similar errors on other template names, and then copy it on this model and the value of defaultTemplateBindings.jtp to PDATemplateBindings.jtp name

    Hi Gschwert,

    in the meantime, I received a response from our developers in Austin.

    Developer Tools Apple which refers to should be X-Code.

    They work with X-Code Version 3.0 and have no problem. They will try to work with your versions (4.2 and 4.3) too and take a look, if there is something special to look for.

    Have you tried using X-Code 3.0? Then you get the same problems?

    while I'm the same report run for 2 days (30 records) it's execution and generate output. But when running for 8 days (200 folders) to show that the error

    based on that, you have to re - check the xml data and the logic model (exclude certain logics complex and step by step, recheck and add logic)

    looks like some data to lead to error can be by division or a molding to the number string or can be some special symbols

    Arrgh, it's something to do with escaping the quotes (I think) in a csv file. When I load as a tab delimited, it works like a charm. I'll look into it later unless someone takes pity on us and answer the question before my lunch.

  • An unexpected error occurred during the generation of the Volume License Installer

    I'm building a Volume of NI Developer Suite 2016 DS1 License Installer.  I created the master suite and the installer from the DVD device drivers successfully.

    However, when I try to create tools Xilinx DVD separated issued with the Game Developer on I get the error "an unexpected error occurred during the generation of the Volume License Installer '.

    There is no other information.

    Nobody knows what is this 'unexpected error' and how to work around.

    Just worked it out.  The DVD contains 2 sets of tools; 14.7 & 2014.4.  You must come down with each of them separately, you can't just select the top-level of the DVD folder as you do with all the other discs in the package.  Would be useful if the error to a little more explicit.

    Hi I have a constant problem I have no idea how fix it. I have Windows Vista Home premium loaded and it works very well when it is running. I can restart the laptop several times and it starts perfectly, if I turn it off for an hour or two and go to start it always happens with a different error during the startup sequence. Most of the time I just go to start Windows normally and it loads, other times I have to go to the ERD.

    I uninstalled Vista and wipe the system well before reloading (using another drive) and the same thing happens. Would it be more likely to be hardware related? I know the battery charges well and I ran all the tools that Vista has to check the hard drive, so I don't know where to go next.

    Any help would be appreciated.

    Terry

    Hello

    Can you please post what errors you get during the boot process?

    In my opinion it could be a hardware problem, because you have already tried to reinstall Vista, so I doubt that the error is software related.
    Strange, but it might be a problem of RAM or HARD disk. The two parties, you can test it with Memtest86 and Drive Fitness Test. Google is your friend to find these two tools.

    In the worst cases, you must go to an authorized service provider. Technicians can check the entire notebook.
