Calling webservice to retrieve and open PDF file

Yes, but it's not a straight forard opperation. The read stream has to be placed into a context where Acrobat will recognize it as a file. For example, you could write the stream to an attachment, i.e. a Data Object using the "doc.setDataObjectContents()" function. If necessary you can also create a new DataObject of the correct type for this operation. Then use the "doc.exportDataObject()" fucntion with the "nLaunch" argument to open the file.

This methodology will only work in Acrobat Pro, or with a PDF that has very special Reader Rights Enabling. And the PDFs should be small. It may not work for files over 32k because of object size limits in JavaScript.

Thanks for your detailed answer thomp... the file size limitation looks like a big problem : it will try to investigate a bit more.

Thanks again !
