Insert CLOB data upto 2 GB data

I need to store huge data (which is a xml data) in a CLOB datatype which is running on JBoss server.Iam successful in writing the code but my code has a big limitation that it can store upto 32523 (approx) characters.But,my application will be receiving the xml's of upto 2 GB (Approximately). But,iam unable to find the alternate for this.



When iam using to create CLOB object directly,it is giving Class Cast exception,thats the reason, i have tried using the above code.

I have tried to create clob in the following way which is giving Class cast exception.




Hence i tried using WrappedConnection of JBoss

But still throwing class cast exception.
Did anyone had this kind of issue/problem of storing more than 2 GB data into CLOB datatype?Is there any another alternate for this?
Please let me know

Thanks in advance.

How about storing the monster data as a file with a unique name and putting the name in the database?

We cant save it in the form of a file as we have many challenges in using it.
Is there any other alternate?

What kinds of challenges? Storing it in the DB will present substantial challenges as well (larger challenges probably than using the file system).

Adding a "Me too!"

We have a similar problem to this and storing a handle to the file and using a file system to store the actual file is definitely the way to go, for all sorts of performance reasons etc.

As I understand it, the underlying mechanism by which DBs store large Blob and Clob objects is in fact by writing a file and only storing the file location in the DB tables.
