Thread: CLDC implementation of the pgsql driver.

Hi All,

We would like to hookup our embedded devices to a database connected to
the network. In order for this to succeed we need to change the driver
in some places to allow for the use of the CLDC instead of J2ME java.
Looking at the source it doesn't seem to much to do, but i am concerned
about the commercial usage. When we change the implementation to a cldc
implementation, are we allowed to use this driver for commercial usage?
and if so are we allowed to distribute the binary classes as part of our
product free of charge?

Thanks in advance,

Richard Meester

James,

what is a CLDC compatible driver ?

CLDC does not in fact define a JDBC API.  If you take a closer look at the
Mimer javadoc you can see that it does not do things like implement
java.sql.ResultSet or any other kind of standard API.  What they have done
is just named some objects the same as standard JDBC ones so that you can
write programs by importing their package instead of java.sql.* and
pretending it is JDBC.

JSR 169 appears to try to standardize JDBC access for CDC, but CDC
appears to be a level above CLDC.  I don't know anything about the J2ME
technology stack and how these are all related or how one would
compile for a CLDC target, but I can say I don't know of any existing
projects to support such a platform.
