document

Hi.
I did a process which implics fill a form and with these variables do a odt and transform to this to a pdf document, the create the odt document is an automatic task, transform odt to pdf is other automatic task but in this task I did a script this returns a java.lang.object when I tried to assign the result to a document this is incorrect.
I tried to convert the pdf file to a document but when I run the process this shows problems in the begining.
I sue xdocreport to create the odt file and transform this to pdf.
Thanks.
