JDK 1.4 and hibernate
by Reza Razavipour
To all,
total newbie to Hibernate. Does hibernate have any limitations running
against KDK 1.4 and JRE 1.4? If so, is there a version that does?
Thanks

Umm, why not have a look at the fix?

if we want to be completely safe then
Thread.currentThread().getContextClassLoader()==null?Environment.class.g
etClassLoader():Thread.currentThread().getContextClassLoader()
would be better since in the case contextclassloader == null then
Connection.class.getClassLoader() is most likely null or point to a
"too-high"
classloader thus using the classloader of Hibernate self would be the
best
fallback.

I committed the fix. Just pointing out that your solution dangerously
looks correct...

But it should then be done in the classloader that loaded hibernate; not
the system classpath loader which Connection.class will be.
You don't get this error at your end ?
At least i'm not the only one

Hi Steve,
After updating from svn I get the following in alot of tests:
java.lang.IllegalArgumentException: interface
org.hibernate.jdbc.ConnectionWrapper is not visible from class loader
at java.lang.reflect.Proxy.getProxyClass(Proxy.java:331)
at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:552)
at
org.hibernate.jdbc.BorrowedConnectionProxy.generateProxy(BorrowedConnect
ionProxy.java:56)

org.hibernate.jdbc.ConnectionManager.borrowConnection(ConnectionManager.
java:163)

org.hibernate.jdbc.JDBCContext.borrowConnection(JDBCContext.java:111)
at
org.hibernate.impl.SessionImpl.connection(SessionImpl.java:359)
at
org.hibernate.test.connections.AggressiveReleaseTest.testBorrowedConnect
ions(AggressiveReleaseTest.java:210)
I fixed it by changing:
public static Connection generateProxy(ConnectionManager
connectionManager) {
BorrowedConnectionProxy handler = new
BorrowedConnectionProxy( connectionManager );
return ( Connection ) Proxy.newProxyInstance(
Connection.class.getClassLoader(),
PROXY_INTERFACES,
handler
);
}
to
public static Connection generateProxy(ConnectionManager
connectionManager) {
BorrowedConnectionProxy handler = new
BorrowedConnectionProxy( connectionManager );
return ( Connection ) Proxy.newProxyInstance(
Thread.currentThread().getContextClassLoader(),
PROXY_INTERFACES,
handler
);
}
Connection.class is always loaded via the boot/system clasloader so I
don't get how using its classloader
when generating the proxy would ever work ?
