Problem with generating entity from table [message #494662]

Hello,

I am creating a project in galileo, with dali 2.2. I also use EclipseLink and Glassfish as a server. The project is jpa enabled, with a pesistence.xml file. I use the wizard to generate the entities from tables.

I may see the tables of my schema in the wizard. In fact everything goes fine up to the finish.

The only thing is that no code is generated and I can't find any message of why it failed.

Any help would be appreciated. If it's not the right place to ask, don't hesitate to tell me.

thanks

Ludovic

Please open the Error Log view and report any errors that might have been logged on the Finish. I'm guessing that there is something being sent to the log that might help us diagnose the problem.

Thanks,
Neil

it seems that the log4j jar is missing. Is it at the plugin level?

thanks

The log4j jar should be in your installation's plugin directory. It sounds like a possible installation problem if it isn't there, or cannot be loaded. How did you install Dali?

Neil,

Thanks for your answer.
I installed from the yoxos free download. (Java EE profile + a couple of other plug-ins).

I just checked in the plug-ins detail of my eclipse installation and I can see the Apache Jakarta log4j plugin (plugin id = org.apache.log4j).

I still have the same error.

thanks

Ludovic

If you have time, give the base Java EE package a try and see if you have the same problem.

Yes I tried, it's working fine with the eclipse distribution.

Something is wrong with the yoxos one. Weird because I just dowloaded the default JEE package from them, so it should work the same as the eclipse one.

thx
