I have created a hbm.xml mapping file for a particular entity. When I right-click on the file in MyEclipse (4.1.1) Package Explorer and choose “Generate Pojos” it generates a java.lang.NullPointerException.

Stacktrace:

The mapping file is:

Can you click your MyEclipse menu item, then click “About MyEclipse” then click “Configuration Summary” and paste the result here for us?

Are the hbm.xml files you have selected in a MyEclipse Hibernate project? This is mandatory for the POJO generation to work properly.

If not, add Hibernate capabilites to your project (please refer to the Hibernate help included with ME for further instructions and detail) and then re-invoke the wizard.

Let us know if you require further assistance or it still isn’t working.

Best,
Brian.

Ok, that fixed the problem. In a future revision, you might consider not having “Generate POJOs” as an option if you don’t have hibernate project capabilities.

Thanks for your help.

I agree, I’m surprised that wasn’t done already. We’ll take care of it in our next release.
Thank you for reporting back 🙂

Best,
Brian.
