JOpera for Eclipse

Dear JOpera team,

I plan to apply JOpera in a project, because of its
outstanding agile composition approach and light-weight
interfaces. Though the data processed is mainly XML and
it relies at least on XML transformations. Currently
XSLTAdapter does not seem to work, its System output is
empty although the task finishes successfully. Is there
a any workaround ?
Thank you
Jaro
