JDBC issues for JDK1.4

Hi folks

I'd like to make the JDBC driver comple with JDK1.4. I've got the
following list of errors and potential remedies. Does anyone have any
objections if I start work on this?

The following are the methods defined in JDK1.4 which are not currently
implemented in the JDBC driver:

javax.transaction.RollbackException is not defined in 1.4.
-- this appears to be renamed to TransationRolledbackException

Statement.getMoreResults(int)
-- defines the behaviour of the current ResultSet when the next one is
retrieved. Appears that we need to simply perform appropriate operations
on the result instance field of jdbc2.Statement.

PreparedStatement.setURL(java.net.URL)
-- Presumably convert the URL to a string and set it like everything
else?

CallableStatement.registerOutParameter(String, int)
-- There are a bunch of these actually, javac is only listing one. They
all take parameter names rather than indexes. Should be straightforward
to fix?

Connection.setHoldability(int)
-- Not too sure about this. It defines the "holdability" of result sets
between commits. Need to investigate further (tips?)

DataBaseMetaData.supportsSavepoints()
-- Presumably: "return false;"

ResultSet.getURL(int)
-- Presumably, "return new URL(getParameter...));"

PGblob.setBytes(long, byte[])
PGclob.setString(long, String)
-- This stuff looks harder, there are setBinaryStream() etc methods. Not
sure how to go about this at this stage. Maybe an Unsupported exception?

ClientConnection.setHoldability(int)
-- presumably, pass the call to Connection.setHoldability()?

Feedback/comments welcome.

Cheers
Mark
