A Major Transaction Problem!

Question

"A" is a record which has already been inserted into a table(TBL).
"insert(Y)" is a method that inserts a given record -Y- into TBL.
"foo(X)" is a method that takes a record as a parameter and queries it on a view(VIEW). This view is a
huge select statement that selects from TBL.
Here is the problem:
insert(B);
foo( A ); /* returns true */
but
insert(B); /* B does not exist in TBL */
foo(B); /* returns false and catches an exception that "A" is not found! */
insert(Y) method is a CMP EJB method but foo(X) uses JDBC to access DBMS.
so what can cause this transaction problem?
thanks in advance,

Hi,
Maybe foo is running in a different transaction than insert?
Some possible causes:
-you are starting a new transaction for foo, either via the UserTransaction or via REQUIRES_NEW
-you are using a regular JDBC driver for foo instead of an XADataSource.
Did you try to set foo's transaction attribute to REQUIRED?
