JAVA Float to int exception

Question

Hi
I am facing a serious problem after migrating application from oracle 9i to oracle 10g.
Application was earlier connected with oracle 9i as database after migration to 10g .
I am facing a problem of float to int exception.
In database,in table where a column's datatype is defined as number() is treated in java as float but
*number(p)[p any integer]* is treated as integer in java.
Earlier when application was on Oracle 9i i never faced this problem but in oracle 10g it is present.
Can some one help me in this issue.
What should i do so that data type number() is also treated as integer in java

You could change your code, or change at table level.
This is not a trivial task, though:
SQL> create table t(x number)
Table created.
SQL> insert into t values (1)
1 row created.
SQL> commit
Commit complete.
SQL> alter table t modify x number(10)
alter table t modify x number(10)
Error at line 8
ORA-01440: column to be modified must be empty to decrease precision or scaleYou need something like:
SQL> alter table t add y number (10)
Table altered.
SQL> update t set y = x, x=null
1 row updated.
SQL> commit
Commit complete.
SQL> alter table t drop column x
Table altered.
SQL> alter table t rename column y to x
Table altered.
SQL> select * from t
         X
         1
1 row selected.Regards
