Hi, I’ soory I dont know where I shoud ask.

At first time on starting up Myeclipse,when I selected Reports_install, I was told to install [PDE].So perhaps I installed it.
Next time I selected Reports_install,but it happened Dupulicate ERROR.

Now I cannot find [MyEclipse Report Design perspective] in the Windows-menu-[Open
Perspective].

What shall I do ? I wanna try MyEclipse Reports.

auty,
Are you using Eclipse Europa Classic with MyEclipse 6.0.1 ?

Also, can you go to MyEclipse > Installation Summary > Installation Details and paste the information here for me.

auty,
You cannot use WTP with MyEclipse. If you are using the MyEclipse All in one installer, you dont have to install Eclipse separately. Eclipse and MyEclipse are preintegrated in the All in One installer.

Installer MyEclipse to a brand new location using the All in One installer and then check if you can setup reports.

[auty]

Nipun,

I used
MyEclipse_6.0.1GA_E3.3.1_FullStackInstaller.exe
I could get Myeclipse Reports. Thanks a lot !

Now I have another problem [net/sf/ehcache/CacheException].

Acoording to Hibernate Tutorial,I created simple Java Project.
I got next DUMP.

auty,
You got this error when you created a new Java project ?

Can you switch to a new workspace and try creating a new Java project. Do you still get the same error ?

[auty]

Nipun,
Thanks again.

>You got this error when you created a new Java project ?
Yes.

>Can you switch to a new workspace and try creating a new Java project. Do you still get the same error ?
I switched to a new workspace, and everything has gone well.

I ‘m so glad to get out of troubles,but I want to know the reason because I can correct the old workspace if I can.
Do you have any infomation?

————————————-
auty

[Loyal Water]

auty,
You can try using the -clean command to clean your old workspace. Incase that doesn’t fix it, you will have to import your projects into the new workspace and continue working.

It often happens just after I reinstall Myeclipse.

And,sometimes after reinstalling Myeclipse,it seems to go well at first,
but,once I restart Myeclipse,it continues to dump these messages.

What should I do ?

[Loyal Water]

Can you give me some information about you project. Have you added MyEclipse Hibernate capabilities to your project ?

Can you go to Project > Properties and check which icons are lit up on the MyEclipse page ?

[auty]

Nipun,
I see only Hibernate icon checked on the MyEclipse page.

I found [Window>Preferences>Installed JREs] is queer.
I think a change of JRE affects newly created Java Projects.

But the change affects at once.

I hava two JREs there.
1.jdk1.6.0_02
2.MyEclipse 6.0
When I select MyEclipse 6.0, most things go well.
When I select jdk1.6.0_02,those dumps are emitted at once.
… java.lang.NoClassDefFoundError: net/sf/ehcache/CacheException …

I can see Hibernate 3.1 Core Libraries in my Project ,and ehchache-1.1.jar there.

auty

[auty]

Nipun,
I’m sorry I didn’t add *.jars to classpath when jdk1.6.0_02 was running.
Now it’s all right.

Next using MyEclipse Derby,

[Loyal Water]

auty,
Have you tried running the “Introduction to hibernate” demo which i available for download on the Hibernate tutorial page ? Is the exactly similar to that app or have you made changes to this app ?

[auty]

Yes,I’m leaning “Introduction to hibernate” maybe on my way.The above SQL is taken fron Myeclipse Database Explore.
When I was working with other Project using HTML,Myeclipe suddenly got down so I have restarted Myeclipe.

As you suggested the original Sample(IntroductionToHibernateProject.zip),I imported it.
I changed a few items(Mysql database name,catalog,password) and then everything is goot.
When I returned to my old project avove,though I don’t guess why,everything is going well now.

I learned that it is important to go back to the origin stable.

Thanks a lot all the time !

[Loyal Water]

Your Welcome.
