Interaction between Writer and JavaBeans with Oracle Forms

Question

Hi, guys,
I've been facing some difficulties trying to integrate Writer and Oracle Forms Web (10g). I'm able to open a Writer Document by using a JavaBean executed from Eclipse, but I cannot get the same operation working from forms web. Has anyone ever tried to do somenting like that? Is there a solution to communication between Forms 10G and OpenOffice Writer and how to do it?
Thanks in advance.

Answer 1

Hi, François!
Thanks for your prompt answer. But I still have some questions. The Bean I'm using is the OOoBean, provided by OpenOffice and there isn't much documentation around. I have to control the Writer text editor from forms 10G, but I haven't been successful in my goal.
I'll show the code I'm using in eclipse. I need to adapt it to work in Forms 10G.
