Prefixing the schema owner to the table name

Question

I have entity objects in my JClient app that were created from tables owned by USER1. When I connect to my JClient app as USER2 the DML fails because the table names are not prefixed by the table owner (USER1). I don't want to use public synonyms and I don't want to customize my view objects just to prefix the table names with the table owner. How could I prefix all of the table names with the table/schema owner by default?

We have been using another approach. We change the "current schema" at the db session level. This avoids having to define public synonyms and having to fully qualify names. It also allows us to have the same application schema defined multiple times in a db instance, which is useful for testing.
While our real code is bit more complicated, basically we implement the afterConnect() and prepareSession() methods on an appication module with a call to our utility method:
protected void afterConnect() {
super.afterConnect();
setupSession('hr');
protected void setupSession(String currentSchema) {
try {
log.debug("Setting current schema to: " + currentSchema +
" via: call alter session set current schema " + currentSchema);
Statement stmt =
getDBTransaction().createStatement(DBTransaction.DEFAULT);
stmt.execute("alter session set current_schema=" + currentSchema);
stmt.close();
} catch (SQLException e) {
if (e.getErrorCode() == 1435) {
log.info("Couldn't set the current_schema to " + currentSchema +
" because it doesn't exist in the target db.");
} else {
log.error("Error setting current_schema in DB context!", e);
} catch (Exception e) {
log.error("Error setting current_schema in DB context!", e);
}
