Compilation Error while using Hibernate Annotations

[Raj Menon]

hi,

i'm getting the following compilation Error :

[javac] C:\Hibernate\helloworld_JPA\src\persistance\Hiber
nateUtil.java:11: cannot access org.hibernate.cfg.AnnotationConfiguration
[javac] bad class file: C:\Hibernate\helloworld_JPA\lib\hibernate-annotations.jar(org/hibernate/cfg/AnnotationConfiguration.class)
[javac] class file has wrong version 49.0, should be 48.0
[javac] Please remove or make sure it appears in the correct subdirectory of
the classpath.
[javac] sessionFactory=new AnnotationConfiguration().con
figure().buildSessionFactory();
[javac] ^
[javac] 19 errors

There are other errors like :

[javac] C:\Hibernate\helloworld_JPA\src\hello\Message.jav
a:6: illegal character: \64
[javac] @Entity

But I think all these will be resolved once that AnnotationConfiguration class file is read.

Which JDK are you using? It looks like you are trying to compile 1.5 code with a 1.4 compiler.

[Raj Menon]

Yes Paul,
I'm using JDK1.4 only.

I got the point that lines like
@Entity ,@GeneratedValue
using 1.5 coding,right?

Then why is that error with AnnotationConfiguration file?

Is there anything else other than the above that i mentioned.

Thanks for your earlier post and expecting a reply for this one also

Yes. You can't use annotations with a JDK lower than 5.0.

Then why is that error with AnnotationConfiguration file?

hibernate-annotations.jar contains classes compiled by a 5.0 compiler. When you try to use them with a 1.4 compiler the compiler spots that the class version if higher than it supports and compilation fails. So to fix your problem, use JDK 5.0.

Thanks Paul,I got the point.
