Hi

I just want to give the latest Hibernate 3.0 Beta a chance.
Unfortunately I constantly keep getting a UnsupportedClassVersionError.

I created a new Eclipse project, added all *.jars from the lib plus the hibernate3. jar.

My guess is, that there's somehow a hibernate2.jar hanging a round, but I cannot find it.
I already checked the CLASSPATH environment variable.
I'm also sure I'm using org.hibernate instead of net.sf.hibernate.

Any ideas?

Hibernate version:
3.0 beta 3

Mapping documents:





Code between sessionFactory.openSession() and session.close():


Full stack trace of any exception that occurs:


Name and version of the database you are using:
MySql 4

hmm - looks like the last H3 is compiled with jdk 1.5 (bad gavin!)
This is not necessary.

Best advise now is to check it out from cvs and do the build your self with jdk 1.4 (or simply run it with jdk 1.5)

Thanks Max

Just found the same answer myself.
Recompiling with JDSK 1.4.1 helps.

Hi,
Would be great if anyone could post a J2SE 1.4 compatible version of the Hibernate jar.

Thanks in advance...

My symptom is following...



I work with both 1.4 and Java 5 and it works great in Tiger...

Ugh. Me Very Bad.

We will have to re-do this w/e releases, I guess.

Bugger.

Is this the same error ? Looks like my h3 test is on hold ;-)

same error - recompile h3 your self or run with jdk 1.5 or wait for a release that is compiled with 1.4

If I try and compile under 1.4, it turns out the package below is missing form the source code shipped with the latest beta....

org.hibernate.hql.antlr

which means that loads of classes of won't compile as they are missing imports like the following

import org.hibernate.hql.antlr.SqlTokenTypes;

Hi,

I'm using java 1.3. Do I've to recompile too? - cause I'm getting the UnSupportedClassVersionError when I generate code using hbm2javatask.

Thanks,
Ram Juno.

I suddenly get the same exception.
Does anybody know where I can download hibernate3.jar which is compiled under 1.4.2 ?

If you have java 1.3 or java 1.4 you have to download the source form cvs and recompile the jar file yourself using a compatible jvm

Blah!

I was afraid of that. I tried to run build but it didn't quite work. I will have to look more closly at it later.

I created a jar using 1.4.2 with eclipse on hibernate3 and I used this on my project. However I get the same exception. It must be something else?

Any ideas anyone?
