Ok, what I can request to you write now is to make a simple HelloWorld
singleton. e.g. a singleton having a function which when called
increments
a counter inside it and return the value. I think we'll need two files
for
this (something like XSentence.idl and an implementation of XSentence)
Together with all the above, make the Build.sh file which will be used to
package & deploy that component. And put all of this on a wiki. If you
need
any kind of help, let me know although I'm pretty new to openoffice
development.
Thanks
