Re: fo:external-graphic problem when using HTTPS - EntityResolver?
I have a weird and crazy idea that may help you
Why don't you install a local apache server with mod_proxy.
You can configure mod_proxy so that it can tunnel into https from your http
connection.
1) It's very fast, all my browsing is through a proxy server
2) You can secure your local apache so that it would only allow requests
from localhost
3) It solves your problem by allowing you to make a request via http to
get your https resource.
I am sorry if you find my suggestion ridiculous, but sometimes ridiculous
ideas such as this one can save a lot of heartache and effort.
I guarantee it will work.

Hi,
I have the following external graphic declaration in a XML file:

I render it to a servlet outputstream using:
Driver driver;
driver = new Driver( new InputSource( reader ), out ); driver.setRenderer(
Driver.RENDER_PDF );
driver.run();
This works just fine when having the server configured for HTTP but when
using HTTPS, it fails with error:
Error while creating area : Error with image URL: unknown certificate and
no base directory is specified
I think this is because I am using a own generated certificate and not a
real certificate from f ex Verisign. I know that I can either create my
own SecurityManager (effectively disabling security), or use a real
certificate. I would however like to circumvent all such hazzles and
retrieve the image in some other means instead, intially I tried to use a
custom EntityResolver, but I doesnt seem like it is used for image url
resolution:
i.e.
driver = new Driver( new InputSource( reader ), out ); driver.setRenderer(
Driver.RENDER_PDF );
XMLReader xmlReader = XMLReaderFactory.createXMLReader();
xmlReader.setEntityResolver( new CustomEntityResolver() );
driver.setXMLReader( xmlReader );
driver.run();
Does anyone have any tips how to get the EntityResolver approach to work,
or know any other way to achieve something similar.

Re: fo:external-graphic problem when using HTTPS - EntityResolver?
Currently there's no possibility to set or use an EntityResolver (or
similar) but it's on the todo list. In the meantime you could try to set
the baseURL in Java code like this:
Configuration.put(baseDir, https://myserver/somedir;);
But please be aware that this currently only works in the CVS version of
FOP (branch 'fop-0_20_2-maintain'). The current release only support
local directories, no URLs. This will be in the upcoming 0.20.5 release.

Re: fo:external-graphic problem when using HTTPS - EntityResolver?
Hi Jeremias,
Thank you for answering,
I am already using urls, i.e
http://host.domain.com/webapp/images/foo.gif works, but
https://host.domain.com/webapp/images/foo.gif does not.
Currently there's no possibility to set or use an EntityResolver (or
similar) but it's on the todo list.
Nice to hear, it would be usefull on occasion.

Re: fo:external-graphic problem when using HTTPS - EntityResolver?
Are your images located on the same server as FOP? If yes, you could
access the files directly by filesystem if you set baseDir to something
like:
Configuration.put(baseDir, C:\tomcat\webapps\webapp);
Surely not a clean solution but faster than going via http/https and it
could work for the moment.

It doesnt do the trick for me since I have no idea where any of our

am using EAR file which means that servletContext.getRealPath( string )
wouldnt do it either. I am currently looking into using the
javax.servlet.context.tempdir directory, and put the file there in
init() for later use. That solution would probably work, but I´m not
sure if I can look at myself in the mirror after such a hack...
You can also consider using kind of proxy servlet in which resolve https
image. I mean:
fo:external-graphics
src=url('http://foo.bar/proxyServlet?url=https://real.url')/
