Import utility/mechanism for Oracle in Java

Question

Hi,
Here's my requirement:
I need to upload text(csv) files into Oracle tables through Java code.
The code needs to be generic, so that someone calling it just provides the table name and the file to be uploaded; and the file gets uploaded into the table.
Parsing the file line-by-line is not an option, as:
1. The file/table formats will keep changing during the applications life-cycle.
2. Performance issues, as the file sizes will be huge (>100 MB).
The other option I explored was the sqlldr utility from Oracle. Its quite fast and easy to use but is a command-line utility which would have to be called through the use of Runtime.exec() or similar mechanism, which doesn't seem like a good choice for an enterprise application when seen in the perspective of error/exception handling, code executing outside JVM etc.
Does anyone know of any similar utility written in Java or any other innovative way of handling such a requirement?
Any pointers would be appreciated.

Parsing the file line-by-line is not an option, as:
1. The file/table formats will keep changing during
the applications life-cycle.What's the problem with that? You will always need to specify table name, and columns to insert into. The app will then read the file line by line and insert records into the database (but you should do the inserts in batches, and not line by line)
2. Performance issues, as the file sizes will be huge
(>100 MB).100MB is not huge.
