Hi there,
since there were no responses for on my last post concerning this issue I
tried to debug a bit by myself, hopefully this helps the Torque-Developers
to come up with a solution or further tips.
Again, the issue is: When I try to login I always get "incorrect
username/password" and in the server-log I see the follwing:
---

The error only occurs with oracle (8i), with mysql everything works fine,
but since mysql is no option for the company I'm working for, I have to
solve this somehow.
What I found out so far is:
The original exception that causes the DataBackendException is a
java.util.NoSuchElementException, which occurs in BasePeer in function
CreateQuery(Criteria) line 1110.
---
Iterator it = aliases.keySet().iterator();
while (it.hasNext())
{
1110 String key = (String) it.next();
selectClause.add((String) aliases.get(key) + " AS " + key);
}
Iterator critKeys = criteria.keySet().iterator();
while (critKeys.hasNext())
{
String key = (String) critKeys.next();
Criteria.Criterion criterion = criteria.getCriterion(key);
Criteria.Criterion[] someCriteria =
criterion.getAttachedCriterion();
String table = null;
for (int i = 0; i < someCriteria.length; i++)
{
---
This occurs at the first invokation of CreateQuery during the login
Process. it.hasNext is true, then it enters the while, now it.hasNext is
false and critKeys.next() throws the NoSuchElementException.
What I keep asking me, is: why this only happens with the oracleDB? the
only difference between Oracle and Mysql flow was concerning some limits
settings as far as I could see it.
I only traced this two times so far, there might be other errors.
I also attach the contents of critKeys before and after the while
condition was performed (hasNext()). Interesting to see is, that the
lastReturned value changes, but hasNext() is described as follows:
---
hasNext
public boolean hasNext()
Returns true if the iteration has more elements. (In other words, returns
true if next would return an element rather than throwing an exception.)
Returns:
true if the iterator has more elements.
---
So hasNext() isn't supposed to return an object, but it seems, it does! or
it at least it changes the next-value, because before hasNext() is called,
next() returns the correct element.
I really hope this helps to solve the issue. If you need further
information, please feel free to contact me via email, if you prefer, we
also can speak via Telephone.
Best Regards,
David
