I have had this problem since switching to Geronimo from a "clean"
Tomcat-environment too.
The problem is that Geronimo uses a newer version of CGLIB than iBatis
is
supporting.
I solved the problem by putting the correct version of cglib.jar in my
webapps lib-dir but I think it should also be possible to solve the
problem by using the <hidden-classes>-tag in the geronimo-web.xml to
mask
out the cglib-packages for your application.
Uhm. From what I can see - my geronimo comes with cglib 2.1_3. Also
Spring uses this version. In iBATIS documentation it says that it
supports cglib 2.0, but I can't find this version anywhere (on
cglib.sf.net there are only 2.1_3 and 2.2_beta). Also - are you sure
that when iBATIS is set to useEnchancemnts="false" in sqlMapConfig, it
uses cglib?
Anyway I'll try with different application server in case it's geronimo
problem.
I have tried with useEnhancements="false" as well but it didn't seem to
help. Turning off lazy loading helps but causes other problems in my app
since I depend on the lazy loading of course. :-D
I've tried turning lazy load and enchantments on and off in different
combinations and got problems in all of those configurations. As it
looks like from stack trace logs, cglib gets only used when both lazy
loading and enhancement are enabled. In this case, error messages look
slightly different, because of cglib-generated classes.
Anyway such select scenario that we are talking about SHOULD work
perfectly (even if it's not optimal or smart to use;) without any
magical enhancments and tricks, and it does not, and still it's unclear why.
I found the correct jar by Google but it wasn't easy to find. I can send
it to you tonight when I come home from work if you want it.
Ok. Please send it to my private mail address. Thanks!
I think that <hidden-classes> can be used to mask out the cglib-package
from the classloader for your application though. There was a thread on
the Geronimo-list on hidden-classes just a couple of days ago.
I'll check on that.
Greetings,
-me.
