I download and installed MyEclipse Enterprise Workbench, version: 4.1.0 GA; Build Id: 20060122-4.1-GA.
I tried the tutorial for Hibernate Development, but the examples of the tutorial screens are different from the real product screens.
I create a project, added the hibernate capabilities which generated the HibernateSessionFactory and the hibernate.cfg.xml.

Using MyEclipse Database Explorer, I created database connection for an Oracle 10g database. I opened a connection and selected a schema where I selected a table and tried to generate hibernate mapping. At the end of gerating hibernate mappings, I got the following error message: An internal error occurred during: “Gerating Artifacts”.

The “hibernate.cfg.xml” was not updates. The class mapping files and classes were not created.

I am using Eclipse 3.1, JDK 1.5, Oracle 10g, version 10.2.0, jdbc driver:ojdbc14.jar
😕

Can you check your log file (<workspace dir>\.metadata\.log), near the bottom, for an exception that might give us a hint what happened?

Here are the contents of log file which is the .metadata directory:

java.lang.IncompatibleClassChangeError

It looks like your install is problomatic. This can be caused by upgrading MyEclipse by simply installing a new version ontop of the old one.

I would suggest a new clean install of MyEclipse 4.1 to a new location to alleviate this problem.

[hkaganda]

I unstalled MyEclipse, downloaded again MyEclipse IDE, installed it, but when I tried to create hibernate Mapping, I got the same error. Here are the error messages from the log file:

Here is what I do to create Hibernate Mapping:
After I have created the project and added the Hibernate Capabilities, which creates a session manager file and hibernate.cfg.xml file,
1. I select “create Hibernate Mapping” from the table popup menu, which displays “Generate Hibernate Mapping Dialog”
2. I don’t change the settings on the first screen of the dialog. Then I select next
3. The only setting that I change on this next screen is “ID Generator” which I sent to “increment”, then select finish and that is when I get the error message dialog.

I am testing this on one table which has only two columns with type of long and varchar2 respectively.

What am I missing?

[Riyad Kalla]

When you uninstalled MyEclipse, did you go make sure the MyEclipse directory was deleted as well? If you installed ontop of an old install, you may have files lingering around.

Also please restart using the -clean command line argument as outlined here: http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-10280.html

That will help to make sure everything gets cleaned out.

[hkaganda]

I have uninstalled MyEclipse, deleted the directory, re-started the computer, installed MyEclipse again and added to the eclipse the “-clean” option. However, when I tried to generate Hibernate Mapping, I get the same error message.

I believe the main problem starts when “com.genuitec.eclipse.core” fails to locate “.myeclipse.properties file”.

Any idea why this properties file is missing?

Thanks

[Riyad Kalla]

Can you try a clean workspace: File > Switch Worksspace > C:\tempworkspace, hit OK. And a new project and see if it works?

[hkaganda]

I have already tries switching workspace, but I still get the same error!!!

[Brian Fernandes]

Have you tried a clean hibernate project in the new workspace?

Also, have you installed any other plugins in eclipse? It looks like you may have a copy of Hibernate Tools from JBoss installed in the primary eclipse installation – the same eclipse installation you’re using to run MyEclipse. If this is the case, or if you have installed any plugins that might cause this conflict, can you use a clean eclipse install and test? We just released MyEclipse 4.1.1 which has increased compatability with HIbernate Tools, you could try that too.

Finally, is the oracle driver (ojdbc14.jar) which you copied to your project the same as the driver you configured in MyEclipse to connect to your database?

Best,
Brian.

[hkaganda]

I have installed MyEclipse 4.1.1 and it works. Thank you.

[Riyad Kalla]

Thank you for following up, glad it works now.

[lovethief]

i got the same problem .
why the MyEclipse 4.1.1 i just downloaded can not be installed ??
it asks me to change a new disk……

waiting for your reply……thanks

[Riyad Kalla]

love I didn’t follow your report at all… can you give me some more details? follow our posting guidelines? explain what is going on?

[xwkp2008]
