Hi all,

I have a problem about the hibernate reverse engineering and want your help.

I’ve add hibernate support to a project and reverse engineered a table of DB2 database into a set of codes. But when I want to modify the reverse engineering setting , I right-click the table and select the Hibernate reverse engineering, the wizard does not show at all! Furthermore, the same situation occurs when I want to reverse engineer the other tables in the data base.

But when I close the project, the wizard can display itsself, but at that time , it is useless.

Is here anyone able to help me on this problem? thank you very much!

I have the same problem. I am using Oracle on Fedora 6 and MyEclipse 6M1.
Attached is my installation summary and waht appears in the log.
This works fine on my Windows version.

[bharding23]

Is there any update on what is causing this problem. I have the same issue as the original poster.

I am running on a Linux Fedora Core 7 system. Eclipse 3.3 Europa, MyEclipse 6.0GA. When I first setup the environment (walking through the tutorial) everything work fine. I then go to do my first reverses engineer and again the dialog box pops up and everything is fine.

If I try to do a second reverse engineer the dialog box does not pop up and no matter what I do I can’t get the reverse engineer screen to show.

However, if I go to my project space at the command line and delete everything in the .metadata/.plugin directory (and go through the hassle of re setting everything up) I can then perform another reverse engineer with the dialog box popping up. However, if I try and go back yet again the dialog box will not show up.

Thanks for your reply.

[Loyal Water]

bharding23,
Do you see any error messages in your <workspace>/.metadata/.log file ? Can you try switching to a new workspace and try reverse engineering again. Does it work now ?

[bharding23]

I can reproduce this error consistently.

1) Start a new workspace
2) Create a new Java Project
3) Add my MySQL Connector/J jar file to project
4) Add Hibernate Capabilities to project
5) Switch to MyEclipse Hibernate View
6) Create a new DB Connection using MySQL connector
7) Follow the dialogs to setup Hibernate Session factory, etc..
8) Open DB Profile and navigate to my test database
9) Right click first table and reverse engineer (this works perfectly), and finish the reverse engineering process
10) Right click second table to try another reverse engineer and the dialog box never shows up. You will see the error I get at this point below.

I have reproduced the above steps on the Windows platform and everything works fine. I can reverse engineer over and over with the same project without a problem. It is on my Linux workstation that this error can be found. I have verified I am using the same JDK/JRE on both platforms (1.6_02).

I hope this information helps !! Its killing me that I have to run Windows in a VMWare session in order to use MyEclipse with hibernate. I love this addition to Eclipse

Here is the log output I see when this happens:

[michalzeravik]

I’ve tried to switch to new clean workspace, created java project, run derby, reverse-engineered table; this worked.
But then I tried to rev-engineer another table, wizard didn’t show and found this in log:

Running ubuntu feisty32, sun-java-1.6se, eclipse 3.3 sdk with MyEclipse manually installed.

[Riyad Kalla]

Guys we are testing this across: RH4, FC6, FC7, Ubuntu 7.04 as we speak.

We think we’ve narrowed down the issue to the initialization of a SWT combobox on Linux that is the problem… will keep you informed.

[bharding23]

That’s excellent news! (not for the failure of course but that you guys are narrowing it down) 🙂

MyEclipseIDE has become such an integral part of my development environment, I can’t think of running eclipse without it.

Thanks

[Riyad Kalla]

bharding23,
We appreciate the kind words. We want to be a very valuable addition to all dev environments.

[OlegDuvanayev]

I have now the same problem.
I can’t start second reverce engenieering process. the dialog box never shows up.
I use SuSe10.0

Guys we confirmed the issued on Linux wtih the rev-eng process and should get them fixed in 6.0.1 shortly. We are really sorry about letting this one slip by our QA process.
