JCOM 2004-08-24 - By Ian Vellosa

Hi,
I know a few people including myself who have done projects
using JCom and had nothing but problems! The whole setting up
of the environment appears to be very hit and miss, where
I've not been able to give test and production systems the
same settings and have them both work!! Even the com2java
application generates different proxies depending upon which
machine it is run on! As you can guess from that my personal
opinion would be to avoid it where ever possible. About 2
minutes ago I got an email from a colegue who has just
replpaced JCom access to excel with the POI libraries from
Jakarta and is 1000 times happier with the result. However in
some cases it's not possible to avoid JCom and in my project
I have wrapped JCom access into a JCA which (touch wood) has
been working acceptably well for the last year and a half!
With all the problems we were having the decision was almost
made to write a VB wrapper around the COM application and
expose this via WebServices.
So yes JCom works and does as it says on the tin, but you
will find yourself stumbling through a whole load of
Automation exceptions (some of which I ended up decompiling
JCOM classes to find out what was going on) to get to the
desired result. There is most probably an easier way round
it!
Regards
