I ran my sample hibernate programs in JDK142 fine . But When I tried to compile them under JDK131 I get a version problem . Can we use hibernate 3.1 with jdk1.3 . Please help me .I need them to work in JDK131.



Hibernate version:
3.1.3

Hi,

I think the hibernate3.jar was compiled using a JDK1.4 (Verify this in the META-INF/MANIFEST.MF file inside the JAR file).

I think the JDK you use gives the classes a version number, 47 is for JDK13, 48 for JDK14, and as of what I have seen, 49 for JDK15.

I am not sure, but if there actually is support for Hibernate 3 using a JDK1.3, you would have to rebuild the entire framework.

Hi IOC ,
Thanks . I did do the compiling of the hibernate classes and stuck up with the resultsetwrapper class. This class utilizes the updateArray() of the java.sql.ResultSet which is present from version 1.4 . What should I do about this .

Thanks ,

Hi Ma,

I think they have some sort of wrapper classes that provide the functions that are required but not available on JDK1.3.
Download the whole hibernate project, including sources, modify the build.properties (or the buid.xml) to instruct what is the target vm and then compile the entire framework hibernate.

Good luck!

Carlos
