In my last post i search for help concerning to the use of the libs

Reportlab in to Zope environment. I make some research in Reportlab mailing list and Osmin Lazo (Canada) suggests my to use the following buffer class

######################## # Buffer Class ######################## class buffer:

def __init__(self): self._buffer = [] self._size = 0

def write(self,line): self._buffer.append(str(line))

def read(self): data = string.join(self._buffer, '') return data

def tell(self): return len(self._buffer)

My fistreportlabinzope.py is:

############################# # firstreportlabinzope.py ##############################

import string from reportlab.pdfgen.canvas import Canvas from reportlab.lib.pagesizes import A3, landscape from reportlab.pdfgen.textobject import PDFTextObject from types import *

class buffer:

def __init__(self): self._buffer = [] self._size = 0

def write(self,line): self._buffer.append(str(line))

def read(self): data = string.join(self._buffer, '') return data

def tell(self): return len(self._buffer)

stream = buffer() c = Canvas(stream, pagesize=landscape(A3), bottomup=0) c.setFont("Times-Roman", 12.0, leading=10.0) c.drawString(100,100, "Hello World") c.showPage() c.save() tempfile=open("helloworld.pdf","wb") tempfile.write(stream.read()) temfile.close()

########################3

My main problem is:

When i tried to add the External method i have the following error

message:

IOERROR: [Errno 13] Permission Denied 'helloworld.pdf'

this seems to be a filesystem problem rather than a Zope one- what OS are you on? Are the permissions for the directory set right (Zope runs as nobody on Unix I think) One more small suggestion - the last line of your method has a typo

temfile.close()

I might want to change it to

tempfile.close()
