Hi Vincent,
 
Attached the error when using the snapshot jar in place of the RC1 jar.
Does this help at all?

A bit... My guess is that the xhtml1-strict.dtd is found locally (our URLResolver resolves it locally by transforming the URL into a file name). That dtd references the xhtml-lat1.ent entity as follows:

<!ENTITY % HTMLlat1 PUBLIC
   "-//W3C//ENTITIES Latin 1 for XHTML//EN"
   "xhtml-lat1.ent">
%HTMLlat1;

Note that there's no URL specified, only the name.

On http://sticklebackplastic.com/Posts/PostsByMonth.aspx?y=2007&m=6, we can read:

"
Now the xhtml1-strict.dtd references other files to pull in the actual entity definitions. The XmlReader follows the same procedure - it calls ResolveUri and then GetEntity. The important part to remember here is that these references might be relative. In other words, the dtd might not have fully qualified http URLs. The base URI passed to ResolveUri is the resolved URI of the DocType - "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd". Resolving "xhtml-lat1.ent" against that URL means we should return "http://www.w3.org/TR/xhtml1/DTD/xhtml-lat1.ent", which is the correct location for the entity file. The reader will just download that file and continue.

Of course, it's entirely possible that the reference is fully qualified, in which case, we could just return it directly.
"

What I don't understand is why does it work here and not for you.

I'm using Java "1.5.0_07-164". Maybe you're using another version that has a different xerces version?

I'm sending you a modified core jar to try out (in another email).

Thanks

Hi, and sorry for the late reply.
 
I'm going to be uploading this jar this morning, will take a little while as it's a live system.
Does the system need to access the internet in order to process pdf's now?  This would be the problem - as we use a proxy config script for access; and outside access is restricted on servers.
 
A current page that has this problem, is an article with content set as plain text "this is a test".

Hi Brandon,

Could you send us a page that has this problem so that I can try to reproduce it?

Thanks

My error was slightly different. In my case it's because we don't have the xhtml1-transitional.dtd file locally.

Brandon, I've sent you a snapshot version of the xwiki jar file from the 1.1 branch with more debug logs.

Let us know what you get. I'll continue debugging here.

Thanks

Hi Brandon,

I was able to get something similar to you by going offline and exporting the Blog.WebHome page in the default XE wiki:

I think you may have a proxy preventing the PDF export to go online to fetch the files.

However we have a local copy of these files so they should be used instead of the online version.

Still trying to pinpoint it.

Thanks

Hi all,

Just upgraded our validation servers to the current version (1.0B4 to 1.1RC1) - the problem is, since upgrading versions the PDF printer always returns a blank web page.

Any idea's on how to get this functional again?  This is using the default Albatross skin at the moment.
