Hello leo,

Thanks for sorting out some of the issues. Finally
I have been able to run some code of my application:-)

But one more issue still there :-)
I am getting a stack overflow in a particular case.
      [java] got local db
      [java] WARN   [main] Transaction - ta[id=5102,blocker=null]: uncaught 
exception: (java.lang.StackOverflowError)
      [java] java.lang.StackOverflowError
      [java] WARN   [main] Transaction - ta[id=5102,blocker=null]: uncaught

I am creating a LocalDatabase , putting an object and rertieving that 
object.

LocalDatabase db1;
db1.open("/path/db");
ExternalTransaction tr1 = db1.newTransaction();
tr1.begin();
Foo foo1 = (Foo)db1.createObject(FooImpl.class.getName(),0,"foo");
foo1.setName("Foo 1");  // some operation on foo1

tr1.commit();
db1.close();    // step_middle_1

db1.open("/path/db");   // step_middle_2
ExternalTransaction tr2  = db1.newTransaction();
tr2.begin();
foo1 = (Foo)db1.objectForName("foo");  // get an error here..., stack 
overflow
System.out.println(foo1.getName());  // some operation of foo1
tr2.commit();
db1.close();


Now suppose if I  don't close or open the database in between
(step_middle_1 and step_middle_2) and just commit and open another
transaction, then things are fine.

FooImpl and Foo are the classes with the defined Ozone interfaces
for getting proxies.

Am I missing or doing something wrong over here in the
code above? Thanks in advance. This is the last one for the day!!

Regards
Sunil
