Hi Steve,
Even i was looking into the possible use of XML to move JTable-data back
and forth. However we need to consider the following oints :
1 - The XML document has to be created from the database
2 - this XMl document needsto be parsed and sent to the client.
3 - Every-time the data is displayed/changed/manipulated, the XML doc has to
be iterated. this can be done by putting the whole DOM in memory or through
some other way.
What i ultimately did was I kept another array of changed data in memory
and manipulated this along-with the table models data. This means extra-cde.
However, if we have an XML doc, we can simply have an extra tag which would
indicate the status of the node(inserted/updtd/deleted). this can be decoded
on the server side on save.
these are some thoughts. Let me know what you think.
raaj.
NOTE : I am using GZIPOutputstream for moving data. This probably helps in
performance though I hv not checked it out.
