java - an issue with compatibility: old jboss/hibernate vs Oracle 12c -


i'm oracle-dba trying upgrade our oracle-11g databases onto oracle-12c. our web-developers tell me, there big problem work our old applications (a lot of them developed old jboss 4.2.2 , old hibernate 3.4.0/3.1.0) new oracle-database(12c)

our developers send me information:

**application:

seam-version -> 2.2.2.final

hibernate-annotations-version -> 3.4.0.ga

hibernate-validator-version -> 3.1.0.ga

jsf-facelets-version -> 1.1.14

rich-faces-version -> 3.3.3.final

als dependency: hibernate-core version 3.3.0.sp1 compilieren.

oracledialect: org.hibernate.dialect.oracle10gdialect

jboss 4.2.2.ga

hibernate-version: 3.2.4.sp1

hibernate annotations version: 3.2.1.ga

hibernate entitymanager version: 3.2.1.ga

oracle jdbc driver 11g - ojdbc14

oracle jdbc driver 12c - ojdbc6

so, if call procedure xxxxxxxxx (o_res out sys_refcursor, p_yyyyy in number, .... ) throws problem:

.... info | caused by: org.hibernate.hibernateexception: problem while trying load or access oracletypes.cursor value ..................... info | caused by: java.lang.illegalaccessexception: class org.hibernate.dialect.oracle9dialect can not access member of class oracle.jdbc.driver.oracletypes modifiers "" bug: https://hibernate.atlassian.net/browse/hhh-3159

although, according link should had problem oracle-11g, not while trying upgrade 12c! ( "with oracle 11g, deprecated package oracle.jdbc.driver no longer exists , causes issues oracledialect classes making impossible use hibernate."(с) )

here 1 can read: "try use org.hibernate.dialect.oracle10gdialect, seems highest possible version in hibernate 4.3.9. dialect 12c seems present in later versions, see this." (we have older version of hibernate - 3.2.4 ! )

a newer hibernate (> 3.2.4 ), if i've got right, not compatibe old jboss 4.2.2. (is it?! please disagree me (=with colleagues) if can)

what right decision or workaround make 12c-oracle-upgrade?

thank in advance!
