CHS and asm-errors
Hi,
I'm experimenting to move the CHS from Hibernate2 to Hibernate3.
Thanks to the help of this list, I got the CHS with Hibernate2 finally
running on Cocoon 2.1.7.
Now I'm experiencing errors with my Hibernate3 implementation. It compiles
normally.
But on startup I'm always getting this kind of error:
org.springframework.beans.factory.BeanCreationException...
org.objectweb.asm.ClassVisitor.visit(...) does not exist...
java.lang.NoSuchmethodError....
On the CHS-homepage there was a comment:
>Also, CHS would not start in Cocoon 2.1.7, so I backed out asm-1.5.2.jar
>and asm-util-1.5.2.jar to asm-1.4.3.jar and asm-util-1.4.3.jar.
This didn't help for me. But maybe someone knows (the author of this
comment?) about this asm issue.
Other, non-cocoon-relate question:
I'm working on windows and starting cocoon from cmd. If I get errors I want
to copy the stacktrace, so I can post it here. From the command-window it
isn't possible to copy and paste. What could I do? Suggestions welcome.
thanks
jonny

I haven't worked with hibernate 3 yet.

Hi,
I have a default constructor without parameters for Country. But Hibernate
needs an "empty" constructor, doesn't it?
Could you give me a hint what and where to look for. (This is the CHS with
Hibernate3 modifications.). This Exception tells me nothing.
thanks

Hi,
I commented out BSF and used the latest asm-jars. Now I get following
(differnent) errors on startup:
...
CGLIB Enhancement failed: org.apache.cocoon.petstore.model.Country
java.lang.IllegalArgumentException: Superclass has no null constructors but

What does this tell me now?

I read a post some days ago that bsf relies on asm. If you remove bsf
from your cocoon build you are free to put any asm version into cocoon
lib directory and remove the current one.
BSF is the only block that needs asm:

it's even better - in the properties of command line window check the
'quick edit' checkbox. Then you just have to select the area and press
enter.

No. Should I?
Backing out asm-1.5.2.jar and asm-util-1.5.2.jar to asm-1.4.3.jar and
asm-util-1.4.3.jar didn't help for
me (when I had BSF included) for my Hibernate3 solution.
Has someone got Spring-Hibernate3 experiences?
Laszek: Thanks for the copy paste hint. Saves me a lot of time.
