I read in other post that MyEclipse Installer Team signed the jars on 6.0 but i use 5.5..

Need HELP!!

Thank you,

Alejandro,
This is a known issue and we no longer sign those JARs in our upcoming 6.0 release. In the mean time,what you can do (and might need to do) is download the version of Hibernate you were using from the Hibernate site, and create a User Library with all those JARs in it, and add that to your build path of your project and remove the MyEclipse Hibernate libraries for the time being.

We are really sorry for the trouble.

Hi, I have exactly the same problem – when you say to down load hibernate and create a user with “all those JARs in it” – is that every single jar in the hibernate-3.1.1.zip file, just the hibernate3.jar file? – if all do I have to remove any jars of the same name already in my project?

thanks

harry

[harryajh]

in fact, reading the post again I’m using ME 6 M1 & Eclipse 3.2.2 BUT still get exactly the same error – stopped me completely in my tracks!

any ideas?

[Riyad Kalla]

Harry,
This issue is fixed in 6.0 GA (due out any day now) it wasn’t fixed in 6.0M1, sorry about that.

Also the only JARs you need to replace are hibernate3.jar and the cglib JAR.

[harryajh]

can you please tell me which day? – had to go back to 5.5 which keeps crashing Eclipse under the biggest virus ever release aka Vista!

[Loyal Water]

It was due to be released this weekend. It should be out today or latest by Monday provided we dont run into any last minute issues.

[harryajh]

still no sign – any idea when?

[Riyad Kalla]

Final testing on GA occurring right now. Making sure we didn’t miss anything silly.

I just downloaded and installed 6.0.0GA. Still getting the same error.

[denmills]

I am also getting this error with a new install of 6.0 GA

[lchuenya]

As a workaround, I created my own Hibernate Library as suggested. This didn’t solve the problem until I replace the apache-commons.jar that came with MyEclipse’s Spring Core libraries. Replacing the jar with Hibernate’s copy solved the problem.

[Riyad Kalla]

For the folks still having problems even after 6.0 GA was installed, go to Window > Prefs > Project Caps > Hibernate, and on each Tab, hit “Restore Defaults”

The paths are likely still pointing at the 6.0M1 libraries and not the 6.0 GA ones. Sometimes the project caps do that.

[denmills]

I tried the suggestion to restore the defaults on all of the hibernate libraries with no luck.

The only thing that worked for my project so far (myfaces 1.1 with hibernate 3.1 on Tomcat 6) was to remove the common-collections.jar (version 2.1.1) from the core hibernate 3.1 libraries. There is another more recent version (3.1) of the common-collections.jar file that comes with the myfaces 1.1 libraries. and this seems to work.

Any more ideas on how to resolve this issue or is it just a bug?

[Riyad Kalla]

denmills… so you weren’t having the signed JAR issue that this thread describes, but instead a library conflict?
