When I startup my application either during unit testing or in tomcat, CGLib initialization is failing with a NoSuchMethodError for ALL of my persistent ojbects. Any ideas on how to resolve this, other than disabling cglib? I have included an example full stack trace below as well as an example mapping. As you can see, it's a pretty trivial case.

I appreciate any help.

for me it looks like you are using another version of cglib than the one that hibernate needs.

Yes, I've been looking into classpath/version issues, but haven't found anything. I am using version 2.0.2, which I believe to be correct. It is the 4th entry in my classpath, behind my application classes directory and antlr.

relooking it might be a problem with your SystemParameter class .... anything "weird" about it ? like being final or having no default constructor ?

Not that I see. It is a pojo that extends a serializable abstract base class. In addition to the javabean attributes, it defines static finders. It has a default, no-arg, public constructor and is not final.

Again, it would be for all of my classes so it might be reasonable to suspect the abstract base class is the problem, but this just defines a convenience reflective toString implementation, a logger and a static utilty method.

i must say i havent seen the error before, so to figure it out i would need you to provide a simple failing testcase and add it to the jira.

"getHibernateLazyInitializer" is this method protected ?

Send me this class to baliuka at yahoo.com if you do not want to make it public, I am not sure, but it looks like problem is related to protected method call in constructor.

I have resolved the problem. In my abstract base class, I had the following line of code:

[code]
public abstract class BaseDataObject implements Serializable {

/**
* The log object used to put messages out to a centralized log.
*/
//protected Logger log = (Logger) Logger.getInstance(Hibernate.getClass(this).getName());
protected Logger log = (Logger) Logger.getInstance(getClass().getName());

[code]

The commented out version throws up the gang signs. The other version works fine. I am not sure which I prefer. Well, I prefer the version that works. [/code]

baliukas?

I will test it, probably there is a way to solve this problem.
BTW "lazy" makes no sence in this case, object will be loaded before construction.

This is side effect caused by proxy factory, it creates template for new instances. This template has simplified interceptor, it delegates persistent class method only and fails on any LazyInitilizer method.

and what does that mean in somewhat plain english ? ,)

anything we can do to fix it ?

One of way is to remove this optimization, but proxy creation will be expensive (constructor lookup and syncronized cache). Alternative is to implement fake interceptor for this special case.

I am not sure it is a good idea, but it avoids this error:
