Using a regular expression to remove text which could cause a SQL injection sounds like the SQL statement is being sent to the database via a Statement rather than a PreparedStatement.

One of the easiest ways to prevent an SQL injection in the first place is to use a PreparedStatement, which accepts data to substitute into a SQL statement using placeholders, which does not rely on string concatenations to create an SQL statement to send to the database.

For more information, Using Prepared Statements from The Java Tutorials would be a good place to start.
