Thanks for your mail, but I really couldn't figure out how to use it.
Just wanna rephrase my requirement :
Out of two pipeline calls, from the main pipeline, first pipeline
serializes into image-jpeg, and the other pipeline renders the html
page. Since I didn't and don't know how to take output from one
pipeline whose mime-type is image/jpeg, into the other pipeline and
append the img tag and display this image in the html output of the
other pipeline.
FYI : I found out that inside setup mthd of Transformer I can get hold
of request and since session object..like
this.request = ObjectModelHelper.getRequest(objectModel);
But as i said I m not very comfortable with this solution and want to
know if there is any well or not very well known approach to it ?
Thanks much ...
