thanks for your comments. Yes, I plan to continue the work on this
application and really appritiate comments on the application or
requests on extending the application.
see detailed comments below

Yes that is possible and seems to be a good idea. However, storing
passwords in a file in an unencrypted way seems not to be such a good
idea. Another required extension of the current application is to remove
the hard coded user name and password from different places in the code
and keep it in the session information after entering it once.

Sorry, I do not get the point. The "Specify UDDI" was intented to allow
connecting the GUI to all kinds of different UDDI repositories. In
particular, the original aim has been not to be limited to jUDDI. This
aim has been nearly reached except for the hard coded user name and
password in the different scripts right now. That's the reason why the
values can be changed. Maybe you can try to restate your request. Thanks
a lot.

> -Are you going to enhance this application to include the delete functions?
Deletions are really difficult on such dependent data structures as used
in UDDI. The problem is to keep the data base (UDDI repository)
consistent with the delete operations. In particular, a business (in my
opinion) should only be removed if all services, assertions, etc. have
already been removed, because otherwise there exist data structures
pointing to a business record which has been deleted already. To
guarantee this behaviour via the API is quite complicated and requires
quite some time. Therefore I decided so far not to support deletions of
data. But I am open to discuss this issue and willing to realize it if
the concerns have been discussed.
